Design Guidelines

Because rapid injection moulding is a true injection moulding process, it shares many of the characteristics of traditional injection moulding. Read on to learn more about general design requirements for injection moulding and specific requirements for rapid injection moulding.

General injection moulding design tips

Since Protomold parts are injection moulded, we desire all the basics of good injection moulded part design. We lay out a few of the important points here:

Recommended wall thicknesses by resin type
Uniform wall thickness
Coring Out

Protomold-specific design tips

There are other things a designer should consider when designing parts for the Protomold manufacturing process:

Size limitations
Simple, straight-pull parts
Side Action Support for simple undercuts
The mould core-cavity approach
CNC milling considerations
Part ejection considerations
Part Radiusing and Draft

Miscellaneous
