When it comes to working with a plastic injection molder, there are 10 promises the company should always make before molding any of your parts, particularly mission-critical parts. When it comes to plastic injection molding, temperature plays a vital role in part quality. The most common temperature-induced defects are Warpage, Sink Marks and Jetting. In plastic injection molding, cooling rate is the last section of the molding cycle.

How To Injection Mold Threads

PMC serves a wide range of industries that need to improve an existing product, transition a part from metal to plastic, or bring an entirely new product to market. They are choosing ABS for its enhanced visual appearance, lightweight properties to accommodate color requirements from a variety of end-users.Demand for ABS Plastic Injection Molding Predicted to Continue Seeing Significant Growth Below are the top 5 reasons why manufacturers are now choosing plastic gears over metal. Cause: In plastic injection molding, jetting is most commonly caused because the melt temperature is too low the viscosity of the molten plastic resin becomes too high. This leads to an increased resistance in flow through the mold. When the plastic resin is injected into the mold and makes contact with the mold walls, it’s rapidly cooled viscosity increases. The resin that flows through behind the viscous resin pushes that viscous resin further, which leads to scrape marks on the finished product’s surface. Since the nozzle is the final transfer point from the barrel to the mold, it’s essential to analyze. If the nozzle is too cold, the resin’s travel time can slow which prevents the molecules from getting properly packed. If the molecules don’t pack evenly, they will shrink at different rates which causes mold warping.

How To Reduce Flow Marks In Injection Molding

Unfortunately, burn marks in injection molding are more than just an aesthetic eye sore, they cause degradation within the material and mold properties. This degradation typically results in a compromise of the component’s structural integrity, leading to eventual part failure. Have you ever had an injection molded part that didn’t live
up to its’ use in the environment for which it was intended?  After several attempts to correct the
problems did you give up and choose a metal instead?  These plastic injection molders use what are called commodity resins, such as polyethylene and polypropylene. These are common resins that are not engineered for extreme conditions. If your parts have stress cracks, you should work with a plastic injection molding company that has in-house Master Molders. Plastic Molded Concepts is one of the very few plastic injection molders in the U.S. (and the world) who uniquely specializes in engineering grade resins. PMC provides plastic injection molding services for mission-critical parts that play vital roles in markets like aerospace, military/defense, medical, automotive, electronics and more.
