High Pressure Die-casting With more than 20 years of experience in high pressure die casting, we manufacture high volume, innovative and lightweight die castings to serve customers in automotive, aerospace, bicycle, electric tools, AI, medical devices industry.

Zhongmei Technology owns large workshop equiped with 30 die casting machines ranging from 300 to 3,000 tons, enable us to provide a large range of light metal casting sizes and weights.

A molten charge (which is more material actually needed to fill the casting) is ladled from the crucible into a shot sleeve. From here, a plunger, hydraulically operated, is used to push the molten metal into the die.

The extra material from the molten charge serves to force extra material into the cavity, supplementing the shrinkage that takes place during the solidification process. Machinery used in this type of die casting process can obtain pressures of over 10 000 psi (or 70 000 KPa).

The cold-chamber casting process:

First, the die is closed after which the molten material is ladled into the shot sleeve.
The hydraulic plunger is now used to push the molten material into the cavity of the die. The plunger is held under pressure until the solidification is complete.
The die is now opened. The hydraulic plunger advances in order to ensure the castings stays in the ejector die. If there are any cores present, they will react at this stage.
In the final stage, the ejector pins will expel (or eject) the casting from the ejector die. After this has been successfully completed, the hydraulic plunger will return to its original position

Advantages of Die Casting
Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. When you cast a part, you can create complex net shapes, including external threads and complex internal features with minimal draft angles—minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.

In competing with aluminium alloys as structural materials, magnesium alloys have the advantages of low density, high strength ratio, better electromagnetic shielding properties and castability. These result in the preferential use of magnesium alloys in 3C components(Computer, Communication and Consumer product) where lightweight , heat dissipation, electromagnetic shielding is critical.also have extremely broad applications in the fields of automotive, aerospace,outdoor sports and so on.

With the high integration in 3C , removing the excessive heat produced during the operation of electronic components and heat exchangers, which causes the components to fail as a result of overheating or deformation, becomes more urgent. The demand for materials with both excellent heat dissipation and mechanical properties is increasing rapidly. Selecting materials with appropriate thermal conductivity is very important for achieving the best performance of components.

Mg alloys exhibit great potential as heat dissipation materials owing to their smaller heat capacity and better heat dissipation effects than those of Al alloys. Over the past decades, there have been some efforts devoting to enhancing the thermal conductivity of Mg alloys with a clear understanding of the fundamental heat transfer at the micro, nano and even molecular scales.

Aiming to develop a Mg alloys that can provide significantly improved thermal conductivity in comparison to the commonly used AZ91D magnesium alloys, Zhongmei built Research Institute of Magnesium Alloy Materials jointly with the global leading expert, Prof. Pan Fusheng of Chongqing University and his team.

The Research Instittue keep doing experiments & testing , has made considerable achievements
