Injection Molding

In injection molding, material is fed through a hopper into a barrel where a reciprocating screw mixes and melts the material then injects it into a mold.

FAQ: Injection Molding

What is injection molding?

Plastic injection molding is a cyclical manufacturing process that allows for cost-efficient production of a mass number of identical parts made from either thermoplastic or thermoset materials.

How to Improve Consistency in Injection Molding?

Cushion values in injection molding ultimately are an indication of a part’s quality, especially its dimensions. A consistent cushion will create consistent part dimensions.

How to Get Rid of Bubbles in Injection Molding?

It is important to determine which type of bubble your part has, and what the root cause might be. Determining bubble type will allow you to pinpoint the source and determine your next course of action to eliminate the problem.

How can I improve my injection molding quality and productivity?

Most molders are still relying on “general-purpose” screw designs that go back 30 years. With all of the technical improvements that have been made on machines over that time, nothing has been done to improve melt uniformity. We still use “general-purpose” (GP) screws, which well-known screw designer Bob Dray wisely has called “no-purpose” screws. That is they do not melt plastic uniformly. Processing with a uniformly melted plastic would seem like a high priority, but it has seen little if any attention.
