Flash or flashing is one of the most common problems associated with injection molding, the most widely used manufacturing process for plastic parts.

Injection molding flash is when a line of excess material builds up on the outside of a molded part, typically after leaking through the parting line of the mold. A small amount of flash is normal, but too much can affect the cosmetic appearance, surface texture, and assembly of parts.

This article looks at the main strategies for preventing injection molding flash, as well as methods for removing flash (deflashing) after the molding process is finished.

What is injection molding flash?

Flash is excess plastic that forms on the surface of parts made by plastic injection molding (or similar processes like casting). In most cases, flash occurs when material escapes between two mold halves, at the parting line.

Injection molding flash can vary in severity. Molded parts will almost always display witness marks — signs of tooling features like core pins — and product designers should design parts so these marks are as inconspicuous as possible. One type of witness mark is the witness line: a line on the molded part that shows the parting line of the mold halves.

Flash can be considered a more severe case of a witness line. Flash is not only visible on the surface, it physically protrudes from it. This can cause numerous issues: the flash may be sharp, making the part dangerous to handle, or it may prevent the part from mating with other components due to its reduced dimensional accuracy.

Injection mold flash can have several causes, including:

• Poor alignment between mold halves
• Worn, damaged, or dirty molds
• Poor venting
• Unbalanced plastic flow
• Insufficient clamping force
• Low plastic viscosity

In general, up to 0.1 mm of flash is considered acceptable unless the part has unique needs in terms of surface flatness. It is possible to reduce flash below this amount, but the cost of tooling may increase.

Preventing flash

Preventing or minimizing flash can involve steps at both the moldmaking and molding stage. Better molds are less likely to produce flash, but proper handling of the molding process is also essential to minimize flash and other injection molding defects.

Tooling improvements

Most flash occurs at the parting line of the two mold halves, which makes the mold halves themselves obvious culprits. When the mold halves are not properly aligned and do not fit snugly together, they cannot properly close, which allows material to escape. This escaped material then solidifies as flash on the outside of the moldings.

During the toolmaking stage, the process of mold fitting is carried out to ensure that the mold halves fit together properly without gaps that can cause flash. If the mold halves are not properly aligned, it becomes very difficult to eliminate flash.

Toolmakers are also responsible for the venting of a mold. Vents in the tooling allow air to escape, which enables the molten plastic to fill the mold cavity entirely. Proper venting can also minimize flash. How? Poorly vented molds require higher injection pressures, which can end up forcing the two mold halves apart, creating a gap between them which leads to flash.

Another tooling consideration is flow paths. If some flow paths to the mold cavity are longer than others, unbalanced filling can occur, leading to discrepancies and air traps throughout the mold cavity. Unbalanced flow can also cause flash. Flow leaders and deflectors can be used to ensure balance during filling.

Of course, molds are not indestructible, and wear over time can worsen mold alignment and create gaps that lead to flash. Mold maintenance and refitting should be carried out if the two halves do not fit snugly together, in addition to regular cleaning to prevent buildup or dirt and debris that can prevent effective clamping.

The mold’s parting line placement is another important consideration during the initial moldmaking stage. Although this does not prevent flash, it can ensure that flash occurs in a location that minimizes its aesthetic and functional impact on the part.

Molding process improvements

A well fitted mold is less likely to produce flash, but the molding process itself also contains several variables that can affect the extent of flash on molded parts.

One of the most common causes of excessive flashing is insufficient clamping force. Clamping forces — typically applied via hydraulic or mechanical clamping systems — are required to keep a mold closed during injection, and they must counter the pressure of the injection itself. If the clamping force is insufficient, the mold can open slightly, allowing material to escape and flash to form. High-viscosity materials and thin-walled parts require greater clamping forces.

Uneven clamping and molding forces can lead to other issues like mold deflection, which can also lead to increased flash.

The nature of the molding material can also affect flash. Low-viscosity molten plastic is more likely to escape from the mold and cause flash because it flows more freely and can therefore seep through gaps in the parting line. Although some plastics have inherently low viscosity, the viscosity can be increased by using a lower melt temperature in the molding machine.

Removing flash

Injection molding flash cannot always be prevented prior to molding. Fortunately, it is possible to remove flash from molded parts using post-processing techniques. Removing injection molding flash from finished moldings is sometimes called deflashing. Getting rid of flash is easier on soft materials like silicone rubber but is also possible on hard plastics.

One deflashing method is to use manual tools like a knife or file. The benefit of this method is the accuracy: since a human operator is responsible for deflashing, they are able to identify what is waste material (flash) and what isn’t. It is also the most suitable approach for brittle parts that could be damaged by machine-based deflashing methods. But this process is expensive at scale, since the process must be repeated for each individual molding.

Another deflashing option is using a tool and die system. With this approach, the molding is placed within a die shaped like the final part and punched through the opening to quickly remove flash. This option is typically faster than manual trimming for very large batches, though it requires extra machinery and is still slower than batch deflashing processes.

If manual or die punch flash removal is not possible, batch deflashing processes can be employed. These processes are much faster than manual deflashing, but there is a risk that pieces of the component will be broken off accidentally.

One batch deflashing technique involves using blast media, which can remove excess material like flash from the finished moldings. A related method is tumbling, in which the moldings are put in a vibrating chamber along with non-abrasive media like ceramic beads. These techniques can rapidly remove flash from multiple parts but may not be suitable for delicate or brittle components.

Blasting and tumbling can both be assisted by cryogenic freezing of the moldings. By using a cryogen like liquid nitrogen, operators can make the flash extremely brittle, which allows it to be more easily removed via blasting or tumbling. Using cryogenic deflashing and cryogenic deburring techniques can help maintain critical tolerances and consistency between parts.

As a major source of manufacturing revenue, the defense and military industries rely on some very flexible, cost-effective and reliable technologies. With global defense spending expected to grow at a CAGR of about 3 percent over the 2019–2023 period, reaching US$2.1 trillion by 2023, they also invest heavily into modern machining solutions in various different sectors of their workflow.

The general requirements of military equipment can vary immensely, but a few things apply across the board. In general, military-grade equipment needs to be rugged, rigid and work well within harsh terrains. A lot of the large equipment is metal and requires metallic parts, but there is also a place for medical supplies (which must be approved by military authorities, the FDA or whatever government regulations may apply depending on the region).

Since defense applications can cross over with other industries like communication, medical and aerospace etc., this often means that they use all of the machining facilities specific to these industries as well. The machines often have to be large and capable of processing materials like alloys and hard, durable metals.

Here are just some of the ways the defense industry implements CNC machines and how they bring something unique to the table:

Aerospace Applications

One of the major users of CNC manufacturing technologies is Lockheed Martin. Not only is Lockheed Martin arguably the biggest name in defense manufacturing, they are also the third biggest aerospace firm in the world, behind Boeing and Airbus. However, the company has slightly different needs from the other two as it has a much larger focus on defense. This is where precision machining technologies come in, providing major part accuracy, process reliability and cost savings.

While CNC machines have been used in military applications since their inception, modern mills and drills offer something unique that most other manufacturing technologies cannot match. The precision alone allows for far more novel military applications. The composite skins on the F35, for example, are milled and drilled to such close tolerances that the plane’s assembled surface avoids the mismatches that can show up on a radar.

In the case of the F-35, manufacturers use a five-axis milling machine with an overhead gantry, which provides ample power for their precision-machining operations on the composite skins of aircraft. It also manages complex carbon fiber reinforced plastic parts along with the aluminum vacuum fixtures that hold the part during manufacturing. A single machine alone drills numerous types of parts for all sections of the aircraft and for the manufacturing process itself.

Similarly, Northrop Grumman is another aerospace defense contractor that is finding CNC machines to be the best way to achieve their goals. They have a long-standing partnership with world-class manufacturing conglomerate Siemens to use their systems and has invested a ton of money in developing new technologies for their own use. Northrop Grumman’s research has indicated that the main categories a CNC machine needs to fulfill (for defense applications) are robust machine design, machine tool repeatability, machine tool responsiveness, environmental temperature stability and stable machine foundation.

Northrop Grumman’s Hawthorne plant uses two-gantry, 5-axis Cincinnati Vertical CNC Routers with adjustable CNC fixturing to bypass build and setup costs for hard tooling. Three adjustable beds of new POGO Universal Holding Fixtures (UHFs) cut setup times by about two-thirds on trimming and hole drilling operations on more than 100 different fuselage skin parts. These systems are a crucial part of speeding up their operations and work alongside the NC machines in their arsenal.

General Atomics has also been an enthusiastic endorser of CNC machining technology (among many others) in their aircraft development. Their work with the Predator craft is one great example. It serves as an all-composite aircraft hand layed up at one of their fabrication facilities south of Rancho Bernardo, Calif., using primarily carbon/epoxy prepregs, and cured in an autoclave. The prepreg materials are cut on a computerized cutting and kitting machine and core cutting is done on a 5-axis CNC cutting machine.

Weapons Development

4-axis CNC machines were used to develop Tomahawk missiles as far back as the Gulf war. This trend has only gone deeper as the technology advances, bringing in multiple axis machines with large workspaces and volumes that can create the skin of a missile in one workflow. Aside from precision, such systems require a lot of torque so that they can mill tougher materials. Needless to say, missiles like the Tomahawk require large, heavy-duty systems which also need to work with some pretty powerful materials as these weapons often need to withstand ship travel and even submarine conditions.

To develop these, Raytheon uses a FANUC six-axis robot. This allows a single department to manufacture the entire 20-foot cruise missile on its own, with the robot doing most of the heavy lifting. As one may imagine, it is a dangerous task, so having as little manual labor is a massive benefit for the company. Using robot assembly is therefore not just cheaper, faster and more accurate, but also actively safer.

Small components for missiles and vehicles are being developed all the time using multi-axis machining technologies. Helicopter components like rotating and stationary swashplates, main and tail rotor hubs and main rotor sleeves are all being developed with CNC machines at Sikorsky’s facilities for example.

Even vehicles like the Hummer H2 use multiple components that are milled. A good example is the grill in the front, using aluminum and high-tolerance steels. These are much quicker to make and assemble thanks to the unique advantages of CNC machining.

Detection Systems & Radar Tech

Detection systems and communication devices are always necessary for defense and military facilities. As such, providing and maintaining them has always been the remit of the latest in manufacturing technologies. This is another area where CNC machining can excel when used as a bulwark for the military’s operational needs.

Radome and radar dish development requires uniquely laborious shapes and fine finishes. This is so that they can pick up very minute signals, which one would need for weapons detection systems. This often means that the CNC machined components have to be smooth and precisely curved in all the right ways.

Even aside from these detection systems, their casings are also machined and milled. Having high endurance becomes especially necessary as they often have to part of military vehicles that will either go at high speeds or need to withstand a great degree of wear and tear. Radars can consist of multiple metals and alloys, so any CNC machine handling these has to bring a fair deal of versatility to the table.

The toolset is a key step before the CNC turns off parts. Accurate and fast tool-setting methods are an important prerequisite for ensuring the precision and efficiency of CNC turning. Taking the external contour and internal contour tools commonly used in CNC turning as examples, combined with virtual simulation software, the tool setting methods of various turning tools are deeply explored, providing a theoretical basis and simulation reference for tool setting for operators engaged in CNC turning.

The CNC lathe processes parts by formulating the processing plan according to the technical requirements of the part drawing and then compiling the corresponding CNC program in the prescribed program format and code. The CNC program controls the movement of the moving parts of the machine tool to complete the processing of the parts. The CNC program is compiled according to the coordinates of each node on the part drawing, and the coordinate position of each node is determined according to the spatial orientation of the workpiece coordinate system established by the corresponding tool.

Establishing the workpiece coordinate system on the CNC lathe is the process of tool setting, which will directly affect the processing accuracy and efficiency of the parts. This article takes the outer contour tool and inner contour tool commonly used for shaft parts as an example, and explores various commonly used tool setting methods through CNC simulation processing software.

Tool setting method for external contour tools

 

Common tools for machining the external contours of shaft parts include external turning tools, external grooving tools, and external threading tools. Generally, the tool setting is carried out by the trial cutting method, which is convenient and fast and does not require the addition of auxiliary tooling.

1. External turning tool setting

 

There are many types of external turning tools, such as straight external turning tools, 45° elbow external turning tools, 90° elbow external turning tools, etc. Take the 90°elbow external turning tool as an example. Open the Swan CNC simulation software and select the material 08F low-carbon steel of the FANUC0iT system default material for the blank.

The turning tool generally establishes its workpiece coordinate system origin at the center point of the right end face of the workpiece. The workpiece axial direction is the Z direction and the radial direction is the X direction. Before the external turning tool (T01) is set up for trial cutting, first start the spindle, enter “M03S300” in the [MDI] mode, and execute, as shown in Figure 1 (a); then move the tool manually feed to complete the trial cutting of the right end face of the workpiece, as shown in Figure 1 (b).

Open the [OFFSET SETTING] function on the control panel, and in the [TOOL COMPENSATION/GEOMETRY] interface, define the Z coordinate of the current position of the tool as “Z0”, as shown in Figure 2 (a), and click the gray square button under [MEASURE]. The measurement result is shown in Figure 2 (b). The Z-axis tool setting of the external cylindrical turning tool is now completed.

Figure 1 Z-axis tool setting

Figure 2 Z-axis tool setting parameter settings

The tool retracts in the +X direction, and the X-axis trial cutting positioning is completed during the retracting process, as shown in Figure 3 (a); after positioning, the tool advances in the -Z direction to complete the outer circle trial cutting, as shown in Figure 3 (b).

After the outer circle trial cutting has a certain axial distance, the tool retracts an appropriate distance along the +Z direction, as shown in Figure 4 (a); stop the spindle rotation, open the [Workpiece Measurement] command in the main menu, and use a vernier caliper to measure the outer circle diameter after the trial cutting, as shown in Figure 4 (b).

Open the [Tool Compensation/Geometry] interface, define the X coordinate of the current position of the tool as the measured outer diameter as shown in Figure 4 (b), and enter “X79.482”, as shown in Figure 5 (a); click the gray square button under [Measure] to obtain the measurement result as shown in Figure 5 (b).

The external turning tool alignment is completed at this point, and the tool holder performs the [Return to Origin] operation.

Figure 5 X-axis tool setting parameter settings

2. External grooving tool alignment

 

Turn the tool holder clockwise to turn the external grooving tool (T02) to the processing position. The external grooving tool is also aligned by trial cutting the end face and the outer circle.

Start the spindle, move the tool holder, and make the blade of the external grooving tool lightly touch the end face of the workpiece, as shown in Figure 6 (a); keep the tool still, open the parameter setting page, select the [002] position of [Number], and enter “Z0” for [Measurement], as shown in Figure 6 (b).

Figure 6 External grooving tool Z-axis tool setting

Adjust the tool position and let the external grooving tool test cut the outer circle of the workpiece, as shown in Figure 7 (a); then withdraw the tool in the +Z direction, stop the spindle rotation, measure the diameter of the outer circle tested by the external grooving tool, and input the measured data to the corresponding position, as shown in Figure 7 (b) “X79.130”, and click the gray square button under [Measure]. At this point, the external grooving tool is set up and the tool holder performs the [Return to Origin] operation.

Figure 7 External grooving to cool X-axis tool alignment

3. External thread cutter alignment

 

Turn the tool holder clockwise again, turn the external thread cutter (T03) to the processing position, and move the tool holder. When the tool is close to the workpiece, reduce the feed speed until the tip of the external thread cutter is flush with the end face of the workpiece, as shown in Figure 8 (a), and pause the tool holder feed movement; open the parameter setting interface, select the [003] position of [number], and assign the current position of the tool to “Z0” for [measurement].

In manual feed mode, fine-tune the tool position so that the tip of the external thread cutter slightly touches the processed outer cylindrical surface, as shown in Figure 8 (b), and define the current position of the tool as the workpiece diameter measured after those above 1.2 external grooving cutter (T02) tried cutting the outer circle in the parameter setting interface. At this point, the external thread cutter has been aligned and the tool holder needs to [return to origin]

Figure 8 External thread cutter setting

The above is the tool setting process of the external contour machining tools commonly used for shaft parts.

Tool setting method for inner contour tool

 

Common tools for inner contour machining of shaft parts include inner hole turning tools, inner grooving tools, and inner threading tools. The tool setting of these tools is also the process of establishing the origin of the workpiece coordinate system at the center point of the right end face of the workpiece.

1. Internal hole turning tool setting

 

An internal hole-turning tool (T01) is commonly known as a “boring tool”. Before boring tool setting, the drill has completed the center hole drilling process.

Open the [Quick Positioning] function under the [Machine Tool Operation] command in the main menu, select the center point of the workpiece, click the [OK] button, and get the processing window as shown in Figure 9 (a); open the [Tool Correction/Geometry] interface, assign the current position of the boring tool to “X0”, and perform the [Measurement] operation on it. The result is shown in Figure 9 (b).

Figure 9 Boring tool X-axis tool setting

Fine-tune the boring tool position so that it lightly touches the right end face of the workpiece, as shown in Figure 10 (a); open the parameter setting interface, assign the current position of the boring tool to “Z0” and measure, and the operation result is shown in Figure 10 (b). At this point, the internal hole turning tool (boring tool) is set, and the tool holder needs to perform the [return to origin] operation.

Figure 10 Boring cutter Z-axis tool alignment

2. Internal grooving tool alignment

 

Turn the tool holder clockwise to move the internal grooving tool (T02) to the processing position. After starting the spindle, use the [Fast Positioning] command to quickly move it to the center point of the right end face of the workpiece, as shown in Figure 11 (a), and assign the current position to “X0” in [Number] [002] of the [Tool Compensation/Geometry] interface and measure.

Slightly move the internal grooving tool so that its tool position touches the right end face of the workpiece, as shown in Figure 11 (b), and assign the current position to “Z0” and measure. At this point, the internal grooving tool alignment is completed, and the tool holder needs to perform the [Return to Origin] operation.

3. Internal thread cutter tool setting

 

Turn the tool holder clockwise to move the internal thread cutter (T03) to the processing position. After starting the spindle, use the [Quick Positioning] command to quickly move it to the center point of the right end face of the workpiece, as shown in Figure 12 (a). In the [Number] [003] of the [Tool Compensation/Geometry] interface, assign the current position to “X0” and measure it.

Fine-tune the position of the internal thread cutter until the tip of the internal thread cutter is flush with the right end face of the workpiece, as shown in Figure 12 (b). Pause the tool feed movement, assign the current position to “Z0” in [Number] [003] of the [Tool Compensation/Geometry] interface, and perform the measurement. At this point, the internal thread cutter is aligned and the tool holder needs to perform the [Return to Origin] operation.

Not many school kids are comfortable when teachers ask them to prepare presentations. It’s such a daunting task that students just do whatever they can to avoid making them. Unfortunately, quite a number of adults still think writing a presentation as something too mentally taxing.

When it’s been hours since you fired up Microsoft PowerPoint and you find yourself staring and blanks, you need help. Here are the top 5 things you need to keep in mind when preparing any presentation

Tips for Writing Presentations

#1. Always have an introduction, main message, and conclusion

The basic element grouping for essays still applies to presentations. You can’t just jump into the main message without giving the audience any kind of context or background information. You’ll end up with too many interruptions and questions later on.

Use the first slide to introduce the outline of the things you’re about to cover. Be sure to put the conclusion at the end to sum up the major points and concepts that the audience should pick up.

Both the intro and conclusion should only take one slide. If you can’t put everything in a single slide, that’s alright. Some presentations are longer than others, so if you really have to, spread them into two slides.

#2. Put one idea per slide

As you move from one slide to the next, you’ll realize that putting only one idea per slide makes the transition from one slide to the next seems fluid. You are explaining your ideas one bit at a time and it is easier for the audience to grasp them. The audience knows that when you move to the next slide, you’re going to introduce the next concept or major point.

#3. Keep the text sparse and short

Although the basic elements of a presentation are similar to an essay, you should never plaster every slide with text. Writing a wall of text is one of the most common mistakes people make when making presentations.

Whenever possible, dedicate at most 25% of the available space for text. The more text you put on each slide will only make the presentation looks cluttered.

At the same time, be sure to use short sentences. Bullet points work very well for this because you don’t even need to write complete sentences.

#4. Focus on visuals

Since text only occupies a small portion of each slide, you can fill the rest with visual elements.

Visual elements are integral parts of a good presentation. Charts and graphs are excellent tools to simplify a long-winding explanation. It’s so much easier to understand complex data when you’re using images instead of words.

#5. Prepare a note

Since you’re keeping the slides nice and clean, you should prepare a note. It’s like a cheat sheet that you can peek once in a while as you’re explaining the main concepts you put on the slides. After all, not everyone is blessed with excellent an memory. If you need a note, make one.

—

OK, so those are our simple tips on writing presentations. Just remember that you should prepare the presentation way before you need to present them. Use the extra time to clear your mind so when it’s time to proofread and edit the slides, you can see them with fresh eyes.

If you need help with the proofreading, just copy all the text and paste it on the online spelling checker. It can save you plenty of time when trying to find spelling and grammar mistakes.
