HIPS(High impact polystyrene) is an impact-resistant polystyrene product created by adding butyl rubber particles to polystyrene. This polystyrene product is added with micron-sized rubber particles, and links the polystyrene and the rubber particles together by means of grafting. When subject to an impact, the tip end stress of the crack propagation is released by the … Read more
Steel hardness describes the properties of steels that resist deformation, indentation, penetration, and scratching. steel hardness is important because the inherent resistance of the surface to withstand friction or erosion by oil, steam, and water from injection molding process,there are several harness test method as below: 1.Brinell Hardness (HB) Press a hardened steel ball of a certain … Read more
Thermoplastic Elastomer (TPE) Domestically in China, it is usually known as “TPE”, basically referring to the styrene-based thermoplastic elastomer. The styrene-based TPE (known as TPS in foreign markets) is a copolymer of butadiene or isoprene and styrene block, so its performance is similar to that of SBR. Strengths: High elasticity of rubber and plastic injection … Read more
Warpage as one of the most common defects in a plastic injection molded product, refers to the situation in which the shape of the injection molded part deviates from the shape of the mold cavity. The following is a brief analysis of the factors that affect the warpage of the injection molded products. How the … Read more

Poly phenylene sulfide, abbreviated as PPS, is a new type of engineering plastic, which is mainly divided into two categories: one is a branched thermoplastic polymer with a high viscosity, and the other is a thermosetting polymer which has a linear molecular structure before curing, and can be softened to a certain extent if sufficiently … Read more
Flash, also known as flashing or burrs, mostly occurs between the matching parts of a mold, such as the parting surface of the mold, the sliding part of the slider, the clearance of the insert, and the gap of the ejector, etc. If the flashing is not resolved in a timely manner, it will be … Read more
A plastic injection mold is one of the most important tooling for injection molding, whose quality directly determines the quality of the final product. In the meantime, the mold cost takes up a great proportion in the production cost of an injection molder. If the injection mold life is short and the precision is not … Read more
