Help choosing a material
Compare materials for the loads, temperature and environment your part will face.

For a TPE grip or cushioning layer, bring the base material, contact surfaces and intended use to Aria. We help you discuss the material pair and joint geometry within the overmolding project. The selected grades and the sample evaluation define suitability more clearly than a generic promise of rubber-like feel.
Single-material injection molding, Insert location and retention, Multi-shot / two-shot (2K) molding: Use an injection-molding grade. Fillers, shrinkage and processing temperatures affect tool and part design. Elastomer over plastic, Plastic over plastic: Substrate and overmold are a grade-specific pair. These materials are candidates, not an all-to-all bonding guarantee; qualify adhesion and mechanical retention. Elastomer over metal, Plastic over metal: Metal is the insert or substrate; polymer is the molded layer. Review grade pairing, surface preparation, thermal movement and retention.

We review tool access, geometry and material choice before manufacturing.
Dimensional checks and inspection reports for the critical features on your drawing.
Mold-transferred appearance depends on the resin and tool surface; gloss and texture do not specify a material-independent roughness.
Upload your CAD files and tell us the material and quantity you need.
