Plastic moulds can be divided into three categories, each of which has its advantages and disadvantages. Which of these three types of plastic moulds is more cost-effective? (1) Large nozzle mould: Runner and gate are demoulded together with the product on the parting line. The design is the simplest, easy to process, and the cost

(1) Mold meets working conditions     Wear resistance     When the billet is plastic denatured in the cavity, it flows and slides along the surface of the cavity, resulting in severe friction between the surface of the cavity and the billet, which leads to the failure of the mold due to wear. So the

Plastic mould is for plastic processing and forming. They are made of 45 steel, P20, 718 and other plastic mould steels. The failure analysis of plastic mould can better guide the research and development of mould steel. The failure modes of plastic mould are as follows: Abrasion and Corrosion of Cavity Surface   1) Plastic melt flows

There are many problems to be paid attention to in mould manufacturing. If you don’t know its process and key points, you should learn more about the following knowledge. 1) What is the most important and decisive factor in choosing die steel for mold manufacturing? Forming method – can be selected from two basic material
