Frequently Asked Questions

Have a question about the Engineering Resource Center? Here are answers to our most frequently asked questions. Feel free to contact us regarding any other questions not answered here.

How much does a plastic prototype cost?

Many variables go into pricing an injection molded plastic prototype part. Use ouinteractive pricing calculator as a guide to get an estimate of how much it will cost to produce your part. 

How do I select the best material for my part?

One of the benefits of working with the ERC is that our expert engineers will guide you through material selection and even select alternate qualified materials for you in order to get the highest quality at the lowest cost. Watch this video for a better understanding of our material selection process.

What is the best process for developing my plastic part?

Our Injection Mold Build Classification Guide will help you determine the necessary requirements to build suitable, cost-effective molds within your guidelines.

What is the max part size the ERC can run?

The max part size we can run is 15" x 15". (Small = smaller than a golf ball; Medium = size of a softball; Large = approximately the size of a football.)

What material are the ERC's molds made from?

All of our molds and inserts are made from steel. Read this article to learn why the Engineering Resource Center sticks with steel instead of aluminum.

What is the ERC's modular tooling system?

When the ERC was formed, our engineers realized that 95% of all parts they reviewed needed the same basic requirements for tooling. From these findings, the idea of a modular tooling system was born. It consists of our proprietary steel mold bases and customer-owned inserts. Since insert molds require less material and time to produce, this system makes it possible for our engineers to create plastic injection molded prototypes from your CAD file faster and at a lower cost than other prototype manufacturers.

Are my designs kept confidential?

Unlike many prototype service providers, concept designs and production specifications are kept the intellectual property of our customers.
