Polyvinyl chloride is a polymer formed by the polymerization of vinyl chloride monomer by free radicals, abbreviated as PVC in English. PVC is one of the earliest resin varieties t

Polyethylene plastics Polyethylene refers to the polymer composed of ethylene monomer free poison pumping. The English name is abbreviated as PE. The raw material for the synthesis

Semi-crystalline materials such as POM (acetal), PA (nylon), PBT, and PET (polyester) are easier than amorphous materials. This is especially taken into account when designing mold

Today, parts can be manufactured from engineering plastics using a variety of methods, such as computer-aided design, terminal finite element analysis, and in-mold melt flow calcul

In practice, some injection molding factories often start from their experience with amorphous plastics, adopt a shorter holding time and a longer cooling time, and also often use

The combined working quality of the two parts, the screw and the barrel, has an important impact on the plasticization of materials, the quality of products and the production effi

When using semi-crystalline engineering thermoplastics for injection molding, the correct choice of hot runner determines the function of the mold and the quality of the part. In t

When processing semi-crystalline engineering polymers, choosing the right melting temperature is critical to ensure part quality. Tolerances are typically smaller compared to proce

1. Failure problems and solutions of mold locking: (1): No clamping: Solution: 1):Check the travel switch in front of the safety door, and fix it. 2): Check the 24V5A power supply

The diagnosis of the hydraulic system fault of the injection molding machine is often limited by the on-site conditions, and it is required to eliminate it as soon as possible afte

Both imported and domestic injection molding machines have the following characteristics: 1. The injection molding machine has a large investment in fixed assets, a large productio

Generally, the screw is divided into three sections, namely the feeding section, the compression section, and the homogenization section Feeding section: the bottom warp is small,
