Stress includes thermal stress and mechanical stress, which are mainly caused by mechanical, chemical, operational shock and heat. Explain several aspects after stress generation. 1. In the process of die casting production 1. A cooling temperature control system should be...

A properly designed plastic part can often replace multiple traditional metal parts, and the application range of developing plastic products is also expanding. The proportion is rapidly increasing. As a general term for molds, classification is essential, and the mold...

Conditions for cooling water for plastic mold processing 1. The water transport margin and product material margin are generally not less than 10MM, and should be designed between 10MM-12MM as much as possible; the alloy mold is generally 25MM; 2,...

According to expert predictions, the overall trend of the mold market is steady and upward. In the future mold market, the development speed of plastic molds will be higher than other molds, and the proportion in the mold industry will...

Before designing a plastic mold, it is necessary to understand the requirements of the required plastic parts and production conditions. The following work needs to be done for this. (1) Accept the mission statement The task book for forming plastic...

The development trend of plastic mold processing technology (1) The increasing size of mold-forming parts and the high productivity of parts require a multi-cavity mold, which leads to the increasing size of molds. Large-tonnage large-scale molds can reach 100 tons,...

Plastic mold rapid prototyping technology is a major breakthrough in manufacturing technology in the past 20 years, but only by forming the rapid production capability of practical parts can it truly exert its advantages. Therefore, the research focus of rapid...

How to deal with the deformation of plastic mold in heat treatment (1) Reasonable selection of materials. For precision and complex molds, choose good-deformation mold steel (such as air-quenched steel), and mold steel with severe carbide segregation should be forged...

1. Thermal fatigue crack damage failure During die-casting production, plastic molds are repeatedly subjected to the effects of cold shock heat, and the molding surface and its interior are deformed, which involves each other and repeatedly cyclic thermal stresses, resulting...

Conditions for design of cooling water for plastic mold processing: The water transportation margin and product material margin are generally not less than 10MM, and should be designed between 10MM-12MM as far as possible; the alloy mold is generally 25MM;the...
