Cutting Edge Design: Sharp Edges on Injection Molded Parts

Time to read: 3 min

Sharp edges are beautiful: light glinting off these clean lines as a product rotates through space, music swelling dramatically in the background of a commercial. Edges are precise. Edges are distinct. Edges are horrible for injection molding.

A general rule of injection molding is: Radius all edges. What do you do if your design calls for a sharp line? Fortunately, there are exceptions to this design for manufacture (DFM) rule.

Designing Edges in Injection Molds

Why are edges so difficult? In the injection molding process, plastic is injected into a multi-part mold, cooled, and ejected. For a part to mold well, the plastic must be able to flow easily into the mold, and that’s the first reason that edges should be avoided: Plastic, even melted plastic, doesn’t flow easily, and filling edges requires higher pressure.

Also, when the part is released, edges often stick to the mold, so the defect risk is higher. These both increase cycle time and part cost.

Sharp external edges on a part increase complexity in mold making. Positive and negative space are reversed between the mold and your part: A post on the mold is a hole in the part; a convex hemisphere on the mold is a bowl on the part; and a sharp external edge on your part requires a sharp internal edge on the tool. Why is that a problem?

Think one step back: Before molding occurs, the mold must be made, and is typically machined of high-strength tool steel in two halves. The standard, easiest, fastest, and least expensive, method for making the mold components is to machine the parts using a CNC end mill, where a cutting tool rotating at high speed removes material from the block of steel to form the mold geometry.

Because a sharp corner on a bit wears away almost immediately upon contact with tool steel, endmill bits end up with very slightly radiused corners. Therefore, milling a sharp internal edge in steel is nearly impossible. That means that a sharp external edge on a molded part is also nearly impossible with standard machining. Does that mean there’s no solution?

“Nearly impossible with standard machining”—that’s the key to achieving sharp external edges in molded parts. When the design absolutely calls for a sharp external edge on your part, it can be made with an alternative machining method: electrical discharge machining (EDM).

In the EDM process, an electrically charged electrode comes into contact with an oppositely charged piece of metal (in this case, the steel block to be machined into the mold half), the two charges spark, and a small amount of both the electrode and the metal is removed.

A machined EDM electrode is a mirror opposite of the feature that is being created. This allows sharp edges to be machined into the electrode using conventional cutting tools. These sharp edges can then be recreated by “burning” them into the steel.

That’s the good news. The flip side: An EDM machine is a specialized tool that is more expensive to operate for many parts and is less common in machine shops than CNC mills. So, while sharp external edges can be produced with injection molding, it will increase the cost of initial tooling, as well as potentially increasing the per unit costs.

Contrast that with the sharp edge in the lower-right corner (highlighted above in orange), where the mold tool would require one of the difficult-to-machine sharp internal edges. This edge should be radiused for easier machining with a CNC mill, unless absolutely required. And of course, if it is required, then plan on a slight increase in cost and lead time as the mold is machined on an EDM machine.

Adding Edge to Your Design

Sharp edges are great on knives, scissors, and even MacBooks, but they should be left off your injection molded parts whenever possible. However, when absolutely necessary, the remarkable machining process of EDM will allow your mold tool to be made.

Moussa Dembélé to Celtic, the right move?

After months of uncertainty surrounding Fulham’s Moussa Dembélé’s future, he finally put all rumours to rest this week as he penned a 4-year deal at Scottish champions Celtic, joining newly appointed boss Brendan Rodgers. The 19-year-old youth French international was believed to be one of the most sought after talents in Europe with the likes of Arsenal, Liverpool & even Italian giants Juventus interested in his signature, after scoring an impressive 17 goals in all competitions for Fulham last season in the Championship alongside Ross McCormack.

Dembélé, who was out of contract at Craven Cottage told Celtic TV after sealing the move to Scottish champions:

“I’m happy to be at a massive club like Celtic and I can’t wait to start scoring goals. To be the first signing of Brendan Rodgers is unreal for me. He told me that Celtic is a good team for me. I will have game time. I obviously have to show I can stay in the team.”

Dembélé, who joined Fulham in 2012 from Paris St-Germain, started his career at the family orientated French club US Cergy Clos, which originated as US Cergy, however then merged with Clos Levallois in 1999 to become US Cergy Clos. At the time of merging, the firm was best known for its football school & talented youth, which has now shown to be true after the emergence of Dembélé.

Many have questioned whether Celtic is the correct move for Dembélé, especially after all the big named clubs that were supposedly after him. Why would Dembélé snub the chance to play in the best league in the world, which is arguably the Premier League, or in contrast, move to Italian giants Juventus where Champions League group stage football is available?

The simple answer is, playing time & development. Dembélé who is 19-years of age, turning 20 this July must be playing week-in-week-out as he was at Fulham last season. Dembélé playing in his preferred role as striker almost guarantee’s goals, as everyone saw last season, so why waste it?

In addition to this, if he is playing regularly, he will only improve. Many may argue the case, that playing for the likes of Arsenal, Liverpool or even Juventus is a one in a lifetime opportunity, however what is the use of joining these European elite clubs when one is sat on the bench for what would most likely be 70%-80% of the season?

Another major reason why Dembélé to Celtic makes great sense is because of Brendan Rodgers’s appointment as manager. Rodgers’s spell at Liverpool may not be described as one of the most successful reigns as a manager, however one fact that nobody can dispute is the reputation that he has earned in terms of promoting youth into the first team and developing them into better players.

By placing trust in Dembélé as Celtic’s key striker, Rodgers makes it clear that his philosophy will not change: on the outset, it appears to be a match made in heaven.

This is evident in terms of Rodgers’s past. Just look at the development of names such as Raheem Sterling, Jordon Ibe, Divock Origi, Jon Flanagan, Emre Can & Philippe Coutinho.

Before Rodgers took the reigns at Liverpool in 2012, Kenny Dalglish’s outfit had an average age of 26.4 and was not renowned for playing an attractive style of football.

After the ‘3 years’ in which Rodgers told the media to ‘judge me then’ his team had an average age of 23.2, which demonstrates shows how much trust Rodgers puts into the youth.

In addition to this, Rodgers may have not delivered what every Liverpool fan was hoping for, which was the the Premier League title, however they came ever so close in the 2013/14 Premier League campaign finishing 2nd, two points behind champions Manchester City.

In that particular season, the team was extremely youthful, scoring 101 league goals, the highest number of goals scored by a runner up in Premier League history. Luis Suarez was also top goal-scorer of the Premier League (31) with Steven Gerrard picking up the most assists (13).

One thing every fan that season agreed on was, the football on show could be described as energetic, fast-paced, attractive & enjoyable. These statistics would also most definitely have had a part to play in Dembélé’s choice of signing for Celtic.

Taking this all into consideration, Moussa Dembélé’s move to Celtic is no doubt the right move for his career, as well as his personal development as a player. Working under a manager such as Brendan Rodgers, Dembélé is more than likely to improve and become an even more clinical finisher in front of goal.

Arsenal, Liverpool or Juventus may be in his future plans, however Celtic is the perfect place for Moussa Dembélé right as of now. Under a new manager, playing in a new league, it will most definitely be interesting to see how Moussa Dembélé does at the Scottish champions.

Chappell Roan Is Unrecognizable With Bleached Brows and Blonde Ringlets

Summer 2024 is all about Chappell Roan and we cannot get enough of the musician's ever-changing looks: full green body paint for a Statue of Liberty look one day, an ode to iconic drag queen Divine the next. Roan isn't just packing festivals and dominating streaming services—she's also become a beauty icon for people who want to pile on the blue eye shadow and bright red lipstick and have fun with color.

For a recent appearance on The Tonight Show with Jimmy Fallon, Roan skipped her now-trademark tumbling red curls and bright white face paint in favor of voluminous light blonde ringlets and bleached brows, practically rendering herself unrecognizable from the redheaded singer we've come to love. Hairstylist Dom Forletta was behind the blonde wig, which flowed past the musician's shoulders in small, tight curls, while nail artist Juan Alvear applied extra-, extra-long white stiletto nails painted with a gradient of two Essie Nail Art Studio Gloss shades, Arctic Jelly and Buttercup Jelly. Feathers flow out from each finger to match the feathers on Roan's lashes.

Roan was wearing face makeup, but a subtler shade than her usual chalk white performance color. Makeup artist Andrew Dahling gave Roan's skin a snow queen sheen and applied the aforementioned white feathers to the corners of her lids, painting on a dramatic red shadow underneath the lashline and covering the singer's actual lashes in white mascara for a bird of prey effect. Roan's lips were an antique gold color that mimicked the pale blonde hair.

While she wore a black feathered dress by the Blonds for her convo with Fallon, Roan changed into a white feathered dress with a matching feather crown for her performance, a la the White Swan and Black Swan from the ballet of the same name. “I love looking pretty and scary,” Roan told Fallon of her approach to fashion and beauty, which is inspired by drag, burlesque, horror movies, and theater. “Or pretty and tacky, or just not pretty." According to Roan, she doesn't take her looks too seriously. "I love that fans find such deep meanings to things and I'm just like, ‘I don’t know, I thought I looked hot!'"

HOW TO CHOOSE THE RIGHT TYPE OF GEOMEMBRANE?

How to Choose the Right Type of Geomembrane?

How to Choose the Right Type of Geomembrane?

Geomembranes have become a critical component in modern engineering and environmental projects. These synthetic liners or barriers are widely used to control fluid or gas migration in various industries, including agriculture, mining, construction, and waste management. With their ability to prevent seepage, geomembranes help protect the environment, enhance project efficiency, and meet regulatory requirements. However, selecting the right type of geomembrane can be challenging, given the wide range of materials, designs, and applications available.


Factors to Consider When Choosing the Right Geomembrane

1. Material Type

The material of the geomembrane plays a significant role in its durability, chemical resistance, and flexibility. Common types of geomembranes include:

 

High-Density Polyethylene (HDPE): Known for its high chemical resistance and durability, HDPE is ideal for harsh environments like landfills and mining operations. It’s also one of the most cost-effective options.

Linear Low-Density Polyethylene (LLDPE): More flexible than HDPE, LLDPE is suitable for projects requiring better adaptability to uneven surfaces.

Polyvinyl Chloride (PVC): PVC geomembranes are highly flexible and easy to install, making them popular for smaller-scale projects like agricultural ponds.

Ethylene Propylene Diene Monomer (EPDM): EPDM is an excellent choice for applications requiring high elasticity, such as water reservoirs and decorative ponds.

 

Each material has unique strengths, so understanding your project’s requirements is essential for making the right choice.

2. Thickness

The thickness of a geomembrane affects its strength, puncture resistance, and longevity. Thicker geomembranes are better suited for applications where mechanical stresses, such as heavy loads or sharp objects, are present. For example:

 

Landfills: Typically require a geomembrane with a thickness of 1.5mm to 2.0mm for enhanced durability.

Agricultural Ponds: May use thinner geomembranes (0.5mm to 1.0mm) to reduce costs while still providing adequate waterproofing.

3. UV and Weather Resistance

If your geomembrane will be exposed to sunlight, it’s crucial to choose a material with UV stabilizers. Exposure to UV rays can degrade the polymer, reducing its lifespan. HDPE and LLDPE geomembranes are often treated with UV stabilizers, making them suitable for outdoor applications.

4. Chemical Resistance

Certain applications, such as landfills and mining, expose geomembranes to chemicals that can degrade the material. HDPE geomembranes are highly resistant to acids, alkalis, and hydrocarbons, making them a preferred choice for these environments.

5. Flexibility and Adaptability

For projects with uneven or shifting surfaces, a more flexible geomembrane, such as LLDPE or PVC, is recommended. Their flexibility allows them to conform to the substrate, reducing the risk of tearing or punctures.

6. Cost and Availability

While budget constraints may lead you to consider cheaper options, it’s important to balance cost with performance and longevity. Searching for geomembrane for sale from reputable suppliers can help you find high-quality materials at competitive prices. Investing in a reliable product upfront can save you from costly repairs or replacements down the line.

Choosing the Right Geomembrane for Your Application

Here are some common applications of geomembranes and the recommended types for each:

1. Landfill Liners and Caps

Recommended Geomembrane: HDPE

Reason: High durability, chemical resistance, and impermeability.

Considerations: A thicker geomembrane (1.5mm or more) is ideal for withstanding heavy loads and preventing leaks.

2. Agricultural Ponds and Canals

Recommended Geomembrane: LLDPE or PVC

Reason: Flexibility and ease of installation.

Considerations: Look for UV-stabilized geomembranes for outdoor use.

3. Mining Operations

Recommended Geomembrane: HDPE

Reason: Excellent resistance to chemicals and high durability.

Considerations: Ensure the geomembrane meets regulatory standards for mining applications.

4. Construction Projects

Recommended Geomembrane: PVC or EPDM

Reason: High flexibility and adaptability to complex shapes.

Considerations: Choose a geomembrane with adequate puncture resistance for long-term performance.

Why Quality Matters in Geomembrane Selection

Investing in high-quality geomembranes not only ensures the success of your project but also helps protect the environment. Poor-quality geomembranes may fail prematurely, leading to leaks, contamination, and costly repairs. By prioritizing quality and working with the best geomembrane supplier, you can achieve long-term durability and peace of mind.

Conclusion

Choosing the right type of geomembrane is a critical decision that can significantly impact the success of your project. By considering factors such as material type, thickness, UV resistance, and chemical resistance, you can select a geomembrane that meets your specific needs. Additionally, finding geomembrane for sale from a trusted supplier ensures you get the best value without compromising on quality.

 

Whether you’re lining a landfill, constructing an agricultural pond, or managing a mining operation, the right geomembrane can make all the difference. Partner with the best geomembrane supplier to access high-quality materials, expert advice, and reliable customer support. With the right geomembrane and supplier, you’ll set your project up for long-term success and environmental compliance.
