TOOLING ENGINEERING
Engineering Considerations for 2K Mold Design
A successful two-shot mold requires more than selecting two resins. Part geometry, the first-shot position and the second-shot interface affect tooling feasibility.
Key reviews include shut-off edges, melt flow, gate placement, venting, shrinkage mismatch, ejection and the order of material injection.
MATERIAL INTERFACES
What Makes Multi-Material Tooling Work
The right tooling decision depends on the part function, resin pairing, surface geometry and expected molding conditions.
Material Compatibility
Check the intended material pairing and adhesion mechanism before relying on a rigid-soft interface.
Shut-Off & Interface Control
Review overlap edges, seal-off surfaces and flash risk where two materials meet.
Dimensional Stability
Consider thermal behavior, shrinkage differences and assembly tolerances across both shots.
