What metal materials can be used for die casting?
Oct 10, 2024
There are several metals commonly used for die casting, the most common of which are zinc, aluminum, magnesium, copper, lead and tin. Each metal has its own advantages and disadvantages, and each meets the corresponding industry requirements. Aluminum · Low density/lightweight · High corrosion resistance · High casting temperature · Very stable in nature · High electrical conductivity, which makes...

Why aluminum foil and aluminum profiles cannot be produced directly through the die-casting process
Sep 24, 2024
First, the material properties of aluminum foil and aluminum profiles are not suitable for direct production through the die-casting process. This is because during the die-casting process, the molten aluminum alloy metal liquid contains a large amount of hydrogen, which is difficult to remove during the filling process, resulting in defects such as pores in the produced aluminum alloy die-casting...

How to choose die-casting mold materials?
Sep 19, 2024
Commonly used die-casting mold materials include tool steel, alloy steel and cast steel. Tool steel has high hardness, strength and wear resistance, and is suitable for producing large quantities of products. Alloy steel has high heat resistance and fatigue resistance, and has good stability in high temperature environments. Copper alloy is also an excellent die-casting mold material with good the...

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...

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...

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...

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...
