Demoulding Accessories

Design and functional elements ensuring safe and smooth part release from the mold cavity.

Demolding is the process of separating the plastic part from the cavity and core after cooling. This phase is particularly critical for engineering plastics, deep cavities, thin-wall parts, or parts with negative draft angles.

Proper demolding design minimizes deformation, marks, sticking, and excessive load on the ejection system.

This category includes:

• relief and venting elements
• draft angles and cavity design modifications
• sliding and shaped elements supporting part release
• special surface treatments reducing friction

Key considerations include material shrinkage, plastic type (filled vs. unfilled), surface texture, and temperature conditions. Insufficient demolding design leads to galling, part cracking, or excessive mold wear.
