Avoiding Injection Molding Pitfalls

June 25, 2018

Before we jump into injection molding pitfalls you should avoid, here’s a quick review of the Injection Molding Process, Injection Molding Basics, and Rapid Injection Molding. What is Injection Molding Plastic resin pellets are loaded into the hopper, where it travels into the barrel of the injection molding machine. Through both heat and pressure, the […]

Undercuts in Your Injection Molded Part

June 20, 2018

What is an Undercut An undercut is any indentation or protrusion that prohibits part ejection from a mold. An undercut is a feature that cannot be capture with the cavity and core alone. It is die-locked which prevents the part from being ejected from the cavity. Undercuts can be used to carry out complex forms […]

Overmolding for Plastic Injection Molding

June 19, 2018

What is Overmolding Overmolding is a two-shot injection molding process that creates a single part by combining two separate but complimentary thermoplastic materials. The first shot, called the substrate, is usually composed of a more rigid plastic and is designed to accept the second shot, called the overmold. The overmold is typically composed of a […]

Threads in Your Injection Molding Project

May 30, 2018

Injection molded threads allow you the ability to fasten your plastic parts to other components securely with relative ease. Adding molded threads to your plastic part design can increase parts functionality but if not carefully designed can add unforeseen costs into the manufacturing process. Threads are created from the geometry of the mold cavity. As the […]
