What is Pressure Die Casting?

Custom Pressure die casting is the process of injecting molten metal into a mold cavity under high-pressure circumstances. The process is similar to injection molding and is a guaranteed method of making average to substantial volumes of metal parts.

Xin Pin supplies a great variety of high-grade die casting services for small batch production and a big volume of metal parts with excellent surface and tight tolerance parts. We can use our die casting services to reduce the cost per unit part to accommodate budgetary limitations which is the cost-effective solution to high volumes of metal parts production.

What are the advantages of pressure die casting?

  1. Suitable for mass production, with high levels of accuracy

  2. Cost-effective solution for the mass production of castings

  3. Molten metal solidifies in a matter of seconds, or even milliseconds, for faster production

  4. Ideal for a wide range of applications

  5. Great for highly complex and precise components 

  6. Suited to long production runs or where large volumes are needed

  7. Close dimensional control and very smooth surface finish

  8. Castings with thin walls, and so lighter in weight

  9. Most pressure diecasting’s can be discreetly electroplated without any further processing

Different Types of Pressure Die Casting

1. Rapid Tooling

The most choice for the low volume production, using the aluminum inserts with a lifetime of up to 20,000 runs, typically 1-2 weeks, can reduce lead time.

2. High-Pressure Die Casting

In which a hydraulic ram is used to inject the molten metal into the die at extremely high pressures.

3. Low-Pressure Die Casting

The metal is forced into the mold with air pressure machined in typically 3-4 weeks with a lifetime up to 100,000.

4. Gravity Permanent Mold Casting

This process is combined with a gravity-fed metal delivery system.

The Process of Custom Pressure Die Casting

Our pressure dies casting process consists of 6 steps. It can be summarized as follows:

1. Fixation

Here, the dies are cleaned and lubricated. The die halves are then closed and clamped under high pressure.

2. Infusion

The molten metal is injected and forced into the clamped die under extremely high pressure. The molten metal is kept in the die until it solidifies.

3. Cooling

This process is essential to allow the solidification of the metal. The cooled metal fully forms the part.

4. Ejection

Once the metal has cooled, the ejection process begins. The solidified part is pushed out of the die.

FAQs of Custom Pressure Die Casting

1 What is the minimum pressure for die casting?

100+ will be available. It is flexible, but we always break down the cost as the MOQs which is an economical solution for volume production.

2 What is the difference between high pressure die casting and low pressure die casting?

Low pressure dies casting is similar to sand casting. Gravity is used to fill the molten metal into the mold. This process is much slower, about five minutes or more per part (less than 100 parts per day) than high pressure die casting (more than 500 parts per day), about a part every minute.

3 Which materials do you offer in Die Casting?

We offer casting components built from aluminum, zinc, and zamak which are subject to our customer's requirements.

4 Which types of customers to you supplying?

We are supplying to automobile companies, textile companies, valve, and actuator companies, compressor manufacturing companies, electric and servo motor manufacturing companies, toy manufacturing companies, etc.

5 Can I export my tooling?

Yes, but please let us know before quoting or manufacturing.
