Aiming at this type of two-color/multi-color soft and hard rubber products, let’s share experience of designing two-color product soft and hard rubber exterior molds. Common defects and problems in appearance of soft and hard rubber of two-color products: Soft rubber of second color product is covered with burrs
- Mould strength: insufficient mould strength, which causes deformation of mold plate during injection molding, which will cause burrs;
- Product shrinkage: Shrinkage creates a gap, which is prone to problem of soft rubber drape, and warpage of hard rubber product after mold is opened is easy to crush when second color product is injected;
- Injection pressure: when soft rubber is injected, injection pressure will squeeze hard rubber product;
- Fixed mold packing force: it is possible that product sticks to fixed mold, deforms product or causes product shell to separate;
- Insufficient avoidance: Second color fixed mold and hard rubber part are insufficiently avoided, and avoidance height is not enough to cause crushing;
- Temperature problems: uneven cooling of hard rubber products causes product deformation;
- Product structure: Product itself has design defects, and designer cannot find problem in the early stage with insufficient experience.
