Viscosity is a fluid’s resistance to flow, or the amount of friction that exists in the material. The higher the viscosity, the more friction that exists, so the more pressure you need to inject it into a mold.
One of the first decisions that needs to be made when designing a new injection molded part is which...
There are a lot of moving parts when it comes to injection molding part and mold design. Between product design, material selection, mold design, and processing, collaboration is key to ensure a successful project.
Injection molding is a cost-effective way to produce parts, but there is often a significant amount of waste involved, from inefficiencies to user errors, machine damage and downtime, high scrap rates, and more. Here are 7 ways to lower your injection molding costs so you can improve your bottom line.
Short shots are among the most common and visually obvious quality issues most molders face. So what causes them? How can we prevent them? And how do we troubleshoot them when they do occur? A short shot is when a plastic injection molded part does not completely fill out—a portion of it is missing. A few issues can cause short shots, and the fix is not always straight forward.
