Most of the plastic products we use are made through injection molding, a process in which molten plastic is injected into a ...

Injection is the process step in injection molding that is most critical. The injection speed profile and its repeatability have a direct influence on the internal and external properties of a part.

First, let’s establish that every process must follow normal scientific molding protocol. With pack and hold at zero, the shot should be 95 to 98% full. Temperatures and pressures should be kept as ...

Machine and process troubleshooting are the most important factors in controlling process and reducing defects. Poorly performing presses lead to process variance and uncontrollable scrap events, and ...

Injection molding is a highly-engineered process that demands careful planning and attention to detail if the finished product is to achieve its full potential. The tips in this article should help ...

In the injection molding of plastics, in-mold sensors, as part of a variety of process control packages, have been around for decades. But comparatively recently, similar technology has begun to make ...

Penn State researchers have developed the first powder injection molding process for pure niobium, a biocompatible material similar to platinum and titanium but cheaper. Penn State researchers have ...

Purging a plastic injection molding machine with resin or regrind for color changes or carbon removal often leads to costly waste and lost production time. Along with the right purging compound, there ...
