A brief discussion on the supply chain of die castings
Aug 13, 2024
Describe the principle of die casting in layman's terms. In fact, the working principle of die casting is the same as that of injection molding, except that the injection molding is made of RESIN as raw material, while the die casting is made of liquid metal as raw material. Under the action of high pressure, it is filled into the mold cavity at a very fast speed in a very short time through the i...

Technical points of cold chamber die casting process
Aug 19, 2024
Technical points of cold chamber die casting process: 1. Alloy smelting and treatment The smelting quality of the alloy directly affects the mechanical properties and surface quality of the casting. During the alloy smelting process, the temperature must be strictly controlled, and refining, degassing and slag treatment must be carried out to reduce the generation of impurities and pores. 2. Injec...

What is the mold retention time?
Aug 27, 2024
What is the mold retention time? Mold retention time: The period from the end of pressure holding to the opening of the mold to eject the casting is called the mold retention time. If the mold retention time is too long, the clamping force will increase, ejection will be difficult, and the ejection will be deformed or cracked. If the mold retention time is too short, the ejection will be easy to d...

How to understand the fluidity of die-casting alloy liquid?
Sep 03, 2024
The ability of liquid metal to flow under its own weight is called "fluidity". The test and performance of fluidity is the ability of the alloy liquid to flow to fill the mold and the distance it can flow. The better the fluidity, the longer the distance it can fill and flow. The fluidity of the alloy liquid is determined by the composition of the liquid metal, the solidification method, the shape...
