Planning About the Quality of Die Casting Molds
Jun 18, 2021
The influence of mold pouring system. The pouring system determines the planning quality of a die-casting mold, and it also determines the primary element of the quality of die-casting parts in the later production. As a system, it has many elements. Its attempt is to make the alloy liquid enter the cavity in a suitable fluid state and to fill the cavity to maximize the exhaust of the gas i...

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...

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...

Why copper alloy molds have a shorter lifespan than aluminum alloy molds
Dec 17, 2024
The main reasons why copper alloy moldshave a shorter lifespan than aluminum alloy molds include the following: High temperature and high pressure impact: During the die casting process, copper alloys have a high melting point, fast filling speed, and high filling pressure. Under the impact of high-temperature copper liquid, the mold cavity surface is subjected to great mechanical stress, result...
