A culprit in shrinkage and warpage problems

Residual stress is process-induced stress, frozen in molded plastic parts. It can be either flow-induced or thermal-induced. Residual stresses affect a part similarly to externally applied stresses. If they are strong enough to overcome the structural integrity of the part, the part will warp upon ejection, or later crack, when external service load is applied. Residual stresses are the main cause of part shrinkage and warpage. The process conditions and design elements that reduce shear stress during cavity filling will help to reduce flow-induced residual stress. Likewise, those that promote sufficient packing and uniform mold cooling will reduce thermal-induced residual stress. For fibre-filled materials, those process conditions that […]

Welcome to our Plastic Injection Mold & molding manufacturing Company! Here you find information about custom plastic injection mold and molding processes, techniques, and specialised molding technology so that you keep yourself informed with the latest trends and technology.

What is a plastic injection mold?

Plastic injection mould is a metal steel that has been made the hollow base apart sharp you want and later filled with a liquid or any other material that can use to your idea plastic products which will last millions of cycles. Some of the material that can be poured into the hollow space of the steel include plastic, metal, glass and even ceramic materials. The liquid is allowed to solidify and the block is broken […]
