Why RIM?

Why is the RIM process so special?
It gives you the best value for your budget.

The low tooling investment makes it the ideal process for producing complex, 3-dimensional parts in volumes from a few dozen to a few thousand per year.

The RIM process is unique: two liquids are injected into a mold where they cure and become polyurethane.
The resulting liquid has a very low viscosity and easily fills the mold with hardly any pressure.
Alternatively, traditional injection molding requires molten plastic to be injected at a very high viscosity and temperature into very expensive steel tooling. RIM molding requires tooling (molds) which costs only a fraction of Injection Molding steel tools.


This checklist should help determine whether RIM is the right process for your application.

If you answered YES to at least one of these questions you should have us take a closer look at your project and determine if RIM is technically and economically feasible. It costs you nothing but your time to send us your files for review.
