How to identify the characteristics of inferior aluminum profiles
Apr 20, 2021
Aluminum is divided into raw aluminum cold chamber die casting machine and cooked aluminum. Raw aluminum is less than 98% aluminum, which is relatively brittle and hard, and can only be foundry casting products; cooked aluminum is more than 98% aluminum, which is soft in nature and can be rolled or punched in a variety of utensils. Bengbu Longhua Die-casting Machine Co., Ltd. is a professiona...

What is the effect of induction hardening on aluminum alloy die casting？
May 17, 2021
1.Improve the abrasion resistance of aluminum alloy die-casting Induction hardening was first applied to the surface of the crankshaft journal, and its purpose was to improve the abrasion resistance of the crankshaft. In the past, the crankshaft was quenched and tempered, and induction hardening greatly improved the wear resistance of the crankshaft journal.Die casting machine. 2. Improve the fati...

Common faults and treatment methods of die casting machines
Jul 27, 2021
We will encounter various problems during the die-casting operation. In this editor, we will sort out some common faults in die-casting machines and the corresponding treatment methods. Let’s take the cold-chamber die-casting machine as an example: 1. There is no response to the input operation signal Exclude from the following reasons: 1. The signal input line is not tightly pressed; 2. The fuse ...

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 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...
