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.

Finding Alternative Thermoplastics to PTFE
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.
