Compression molding, also known as hot press molding, is one of the traditional molding technologies for silicone rubber. First, confirmed the design drawings and raw materials with the customer; second, they are heated and melted in the mold; third, extruded with the mold. After heating and pressurizing, the molded product can be obtained by cooling and solidifying. The compression molding method is very suitable for factories with large-scale demand because of its low manufacturing cost and rapid mass production.

Injection molding is a kind of injection molding and molding method. The general injection molding method is to first put the polymer component particles or powder into the cylinder of the injection molding machine, after heating, compression, shearing, mixing and transportation, so that the material is homogenized and melted, and then apply pressure to the molten polymer banyan body with the help of a plunger or a screw. The high temperature FIG is shot into the pre-closed low temperature mold cavity through the nozzle in front of the barrel and the runner system of the mold. After cooling and shaping, the mold can be opened, the product can be pushed out, and the plastic product can be obtained.

What is the process of powder metallurgy? With the ongoing development of new manufacturing techniques and equipment, powder metallurgy has become a crucial part of modern industry. The production process in powder metallurgy can be broken down into five key stages: powder production, mixing, forming, sintering, and post-processing.

This process involves converting raw materials into metal powders. Common methods for powder production include oxide reduction, atomization, electrolysis, rotating electrode, and mechanical milling.

Heat treatment refers to a metal thermal processing technology that changes the chemical composition and structure of the surface or interior of a material by heating, heat preservation and cooling in a solid state to obtain the desired properties. Heat treatment generally includes three processes: heating, heat preservation and cooling, and sometimes only two processes: heating and cooling.

Whether the design of stamping die is reasonable is the basis of improving the durability of stamping die. Therefore, when designing stamping dies, effective measures should be taken against adverse conditions in product forming, which aims to improve the durability of the stamping die. 

Mold is known as the "mother of industry", and 3D printing directly manufactures products without mold over the mold manufacturing process, it seems to be an alternative relationship between them, but the answer is not.

The development of modern manufacturing industry can’t be separated from the mold, this article will introduce the six basic knowledge points to help you better understand this field.
