Static electricity generated on the surface of plastic may cause various problems, such as hindering production, sparks that cause explosions and damage to integrated circuits of electronic equipment, and the method of eliminating static electricity should be combined with the actual production, the purpose of the packaging material (what product to pack), and the customer’s […]
According to the statistics of China Mould Industry Association, plastic moulds have become the most important mould products, accounting for 45% of the total domestic mould output value. At present, the operating characteristics of my country’s plastic mold industry mainly include: 1. High regional concentration The development of the mold industry requires certain upstream and […]
PMMA is commonly known as plexiglass, acrylic and so on. The chemical name is polymethyl methacrylate. Due to the disadvantages of low surface hardness, easy rubbing, low impact resistance, and poor molding flow properties of PMMA plastic raw materials, the modification of PMMA has appeared one after another. Such as the copolymerization of methyl methacrylate […]
Output = displacement of last thread +/- pressure flow and leakage. The displacement of the last flight is called positive flow and depends only on screw geometry, screw speed and melt density. It is regulated by the pressure stream, which actually includes the drag effect (indicated by the highest pressure) that reduces the output and […]
Prefabricated cigarette holder processing Prefabricated cigarette holders have a lot of shapes and sizes to meet different needs. Due to the limitation of batch mold injection molding process, there are currently two main materials for cigarette holders: vulcanized rubber and acrylic polymer resin. It is a great boon for customers and maintenance personnel. Most prefabricated […]
