Advantages and disadvantages of aluminum and steel pressure casting methods

Aluminum and steel casting method is applied when it is necessary to produce complex metal materials, after pouring liquid metal into the pressure mold, the flow will be hardened under the effect of pressure. High force or low pressure.

Casting low pressure by vacuum in the mold will increase the hardening time to harden the metal. German high pressure is to use pressure by pressing from the plunger force to compress.

Pressure casting processes include metallurgical furnaces, casting materials, pressure casting machines and molds.

Advantages and disadvantages of pressure casting process

 What are the advantages of pressure casting?

- Pressure casting creates products with smooth, smooth and smooth casting surfaces and very high precision.

- Easy to adjust the thickness of the material into cast material, can make casting materials up to 1.5 mm thin.

- Casting all kinds of detailed holes with small size.

• Good casting material, minimizing the possibility of pitting or poor bearing due to high material density.

What are the disadvantages of casting pressure?

• Due to pressure during the solidification process, this method cannot be used to make the shape of the holes uneven and accurate.
• Under high pressure, the mold is quickly abraded.

For the case of making liquid metal solid by high pressure, the process takes place as follows: When pouring liquid alloy into the mold, the plunger performs the pressing of liquid alloy, the liquid alloy will follow the pressure that Go to the detailed parts of the template.

The design of the mold has two mechanisms: static and dynamic structure, and when the casting is finished, the movable structure will support taking out the mold. The static structure will assist in removing the excess alloy part from the cylinder mouth of the tong. Then the casting process pressures again and continues.
