How Huangyan Tooling Supports PU Integral-Skin Foam Development

Tool Design Must Reflect Foam Flow

Integral-skin material flows, expands and forms its surface inside the cavity. Parting and injection position directly affect appearance, so formulation, hardness and processing method should be known before tool design.

Coordinate Texture and Venting

Deep texture improves appearance but increases trapped-air risk. Texture, vent grooves and local geometry should be designed together and refined after mold trials.

Use Clear Mold-Trial Feedback

Issues should be documented with photos, locations, dimensions and process records. Coordination between Huangyan toolmakers and Taizhou foam production helps separate tool changes from process adjustments.
