How to choose the right tooling resin for composite molds
Quick answer
Composite tooling selection rests on three criteria: required temperature resistance (HDT), production method (hand lay-up, vacuum, infusion) and target surface quality. For high temperatures use systems like WB-0700 and MEG-2107; for infusion prefer MEI-2500 / MEI-2504.
When selecting a composite tooling resin, first define the cure and service temperature.
Then match viscosity and cure schedule to the process; infusion requires low-viscosity systems.
Frequently asked questions
Which board suits a foundry pattern plate?+
Pattern plates and core boxes typically use modeling boards such as MB-0720 or tooling boards such as WB-1222 / WB-1258; the choice depends on wear resistance and part count.
What is the difference between styling, modeling and working boards?+
Styling (SB) is low-density for form studies; modeling (MB) is medium-density for masters/patterns; working/tooling (WB) is high-density and temperature-resistant.
