Recommended wall thicknesses by resin type
Uniform wall thickness
Coring Out

Protomold Specific Design Guidelines

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
Mold core-cavity approach
CNC milling considerations
Part ejection considerations
Part Radiusing and Draft
ProtoFlow® Fill Analysis

Miscellaneous

Once a part is submitted for a ProtoQuote, there are a few more things that must be chosen to place an order:
