Industrial and consumer products need to rely on quality parts. Since molds have direct involvement over a part’s outcome, many steps are taken by manufacturers when developing molds to ensure they achieve the best final product. One of the last steps a mold maker employs is polishing. This is a vital process for improving a part’s quality, and it’s a method that every injection molder should understand. Let’s take a deeper look into how manufacturers achieve a smoother finish with injection mold polishing.[Read more…] about Achieve A Smoother Finish with Injection Mold Polishing
Since the late 1940s, polytetrafluoroethylene (PTFE) has grown in popularity throughout the years. PTFE doesn’t behave like any ordinary polymer. It boasts many unique properties that are often difficult to replicate. However, its processing limitations and the fact that it lacks some vital properties for certain applications have companies seeking alternatives to this thermoplastic. Over the years, new polymers have been developed to maintain similar PTFE properties while also filling in performance gaps. Let’s review some of these alternative thermoplastics to PTFE.[Read more…] about Finding Alternative Thermoplastics to PTFE
We’re living in a fast-paced market, resulting in sellers wanting their products to be available to the public as quickly as possible. While companies are eager for on-demand manufacturing, plastic injection molders need to ensure they’re fulfilling orders with quality parts. This has led many manufacturers to adopt low-volume production methods to meet the client’s needs while also achieving consistent characteristics and qualities. Learn whether low-volume injection molding is the right method for your business and why many competitors are jumping aboard this industry trend.[Read more…] about Why Is Low-Volume Injection Molding Gaining Traction in the Industry?
On top of the pandemic, the past two years have witnessed an increase in destructive natural disasters. Hurricane Eta rampaging through Central America, the ice storm knocking out power across Texas, and the deadly wildfires consuming much of the United States’ west coast were just a few of the catastrophes of the past year. These devastating natural disasters not only threaten residents of these areas but also create logistical nightmares for many supply chains. Let’s review the push-pull system in injection molding and how it can prepare your logistics for the natural disasters ahead.[Read more…] about Preparing Your Logistics for Natural Disasters: The Push-Pull System
Mainstream polymers are versatile enough to perform a large number of applications. Still, sometimes custom or specially built molded parts – such as for medical and public safety industries – have requirements that some commodity plastics just can’t meet. If a part needs to stand up to harsh conditions such as chemicals and fire, often engineering-grade plastics are the most viable solution. To understand how the application of these special plastics can minimize failure risk and achieve unique specifications, let’s review engineering-grade resins in plastic injection molding.[Read more…] about The Benefits of Engineering-Grade Resins in Plastic Injection Molding
When plastic parts become stuck in a mold, it can result in part defects, breakage of mold components, manufacturing delays, and increased costs. That is why carefully designing an efficient ejection system is key to achieving optimal output and final quality products. To design a system that ejects parts easily, quickly, and consistently, the engineer should pay considerable attention to the ejection surface area, the location, and the ejection type. Let’s take a closer look at these three considerations when designing a plastic molding ejection system.[Read more…] about 3 Considerations When Designing a Plastic Molding Ejection System
