Injection Molding

Overview

Injection molding is a manufacturing process in which plastic material is forced into a mold cavity under pressure. Pelletized resins are fed into the injection molding machine, as well as any colorants required. The resins and colorants are introduced into an injection barrel where they are heated and melted. The material is then forced into the mold cavity where it cools. Once cooled, the part can be removed from the mold cavity.


Our Capabilities

With injection molding machines ranging from 7-500 tons we can provide engineering-grade injection molded parts fast and affordable, reducing your time to market. Our variety of press sizes allow us to meet your plastic injection molding needs from 10 to 100,000+ parts.


Prototype Tooling & Injection Molding

Many rapid prototyping processes are great for testing form and fit, but often times there is simply no substitute for testing with the real injection molded parts and material. When your production tooling won’t be ready for months, prototype injection molding is a great way to receive parts quickly and inexpensively. We can use various materials and techniques to create bridge tooling for prototype testing and evaluation.

How large of a part can you injection mold?

We currently have a shot size range of .152oz – 17oz.

What kind of injection molding machines do you run at Schmit Prototypes?

We currently have mostly Nissei machines with a couple Nestal machines as well.

What is the typical turnaround for injection molded parts?

Lead times for injection molded parts is dependent upon our workload at the time, as well as various factors such as part geometry and quantity needed. Schmit Prototypes has been known to turn parts around within 2 weeks of an order being placed.
