Analysis of the causes of bubbles and warpage deformation of injection molded products The gas bubble (vacuum bubble) is very thin and belongs to the vacuum bubble. Generally speaking, if the bubble is found at the moment of mold opening, it is a gas interference problem. The formation of vacuum bubble is due to insufficient filling into the plastic or low pressure. Under the effect of rapid cooling of the mold, the fuel pulling with

Several trends in the development of automotive mold technology Mould is the basic process equipment of automobile industry, more than 90% of the parts in automobile production need to rely on mould forming. Manufacturing an ordinary car needs about 1500 sets of molds, stamping molds account for about 1000 sets. In the development of new models, 90% of the workload is around the change of body type. In the development cost of new models, about

Considerations, advantages and disadvantages of micro injection molding Micro injection molding refers to the injection molding of products with small volume or very high tolerance requirements and tiny overall feature structure. With the development of technology, it has been applied in various fields such as optical communication, computer data storage, medical technology, biotechnology and watch cameras, high-precision gears, medical sensors, etc. A, micro injection mold design should pay attention to the following. Heat insulation and

Cold glue processing method in tpe injection molding process Stagnation is often encountered in the injection molding process and has to be understood. When the melt enters the filling mold cavity from the gate, the melt flow rate in part of the direction of the melt slows down or stagnation phenomenon. This stagnation can cause many undesirable phenomena as well as many defects. Stagnation is the highest form of melt flow imbalance. The best injection

The causes and solutions of tpe injection molding overmolding glue can not stick tpe injection molding overmolding material is usually the use of soft plastic (TPE, TPR) through secondary injection molding overmolding hard plastic (PP, PS, ABS, PA, PC, PE, etc.), the surface of hard plastic products covered with a layer of soft plastic, improve the beauty of the product, non-slip to improve grip. But in the process of wrapping often appear sticky phenomenon, how
