Low Pressure Die Casting Services

What is Low Pressure Die Casting?

Low pressure die casting is a die casting process that uses pressure in the range of 20-100kPa (2.9-14.5 psi) to inject molten alloy into the mold. It is generally used for high precision parts casting and is suitable for metal alloys with low melting points, such as lead alloys and tin alloys.

Advantages and Disadvantages of Low Pressure Casting

Advantages

High quality castings

Due to the slow metal flow rate in the low pressure die casting process, the generation of air bubbles and defects can be effectively reduced, and the quality of castings can be improved.

Uniform filling

It(LPDC) can fill the metal into the mold at a lower pressure, which helps to achieve more uniform and complete filling and reduces filling defects.

High precision

The low pressure die casting metal injection process is slow and controllable, and thin walls and tiny places can be filled evenly, so the manufactured parts are of high precision.

Disadvantages

Long production cycle

Compared with other rapid casting processes, low pressure die casting has a relatively long production cycle due to the slower metal injection rate and longer solidification and cooling time.

Applicable to specific metal alloys

This casting process is mainly suitable for some metal alloys with lower melting points, such as lead alloys, tin alloys, etc., and is not suitable for metal alloys with higher melting points.

Complex mold manufacturing

LPDC molds usually require high manufacturing processes and precision requirements. Because the mold is affected by injection pressure and high temperature, the mold manufacturing complexity is relatively high.
