Overview of the High Pressure Die Casting Process

High-Pressure Die Casting (HPDC) is a popular metal forming method, especially for light metals such as aluminum and zinc alloys, but also for copper, magnesium and other alloys. As the name suggests, the process involves injecting metal into a mold under high pressure.

• Mold Preparation: In the first stage, a two-part mold is prepared for the metal to be cast. These molds are usually made of steel that is resistant to high temperatures and abrasion.
• Melting and Holding: The selected metal is melted at a temperature above its melting point and the molten metal is kept liquid in a "holding vessel".
• Injection and Cooling: The molten metal is rapidly injected into the mold at high pressure. The metal entering the mold solidifies rapidly thanks to cooling systems.
• Demolding and Cleaning: The solidified part is removed from the mold and the remaining material is cleaned and made ready for surface treatment.
• Post-Processing: Post-processing activities such as cutting, drilling and roughening of the cast part are carried out.

High pressure die casting machines have the advantage of offering excellent surface quality and dimensional accuracy. It also allows the production of complex shaped parts with thin wall thicknesses. This method is preferred in many fields, especially in the automotive industry, as it is suitable for large batch production.

The HPDC process is a highly competitive method in terms of cost effectiveness and fast production times. However, considering the mold costs and set-up processes, it may not be suitable for low-volume production. Factors such as process control, correct machine selection and mold design are vital to increase the efficiency of high pressure die casting and maintain quality.

High Pressure Casting Parameters to Optimize Casting Quality

Optimizing casting parameters is one of the most important ways to increase productivity with high pressure die casting (HPC) machines while maintaining the highest level of material quality. There are a number of important parameters that must be followed to ensure the perfection of the machined parts and reduce production costs:

• Mold Temperature: Optimizing the mold temperature ensures that the metal reaches every point of the mold, preventing premature freezing. In addition, the mold temperature needs to be regulated to prevent thermal stress on the manufactured part.
• Casting Pressure and Speed: The pressure applied and the metal injection rate affect the perfection of the casting. High pressure can reduce the formation of air pockets, but too much pressure can lead to material defects. Correctly adjusting the speed ensures proper spreading of the metal in the mold.
• Mold Design: The internal design and ventilation of the mold improves the quality of the casting by ensuring the efficient removal of gases during the casting process.
• Mold Release Agent and Amount to be sprayed: The type and amount of mold release agent is important to maintain the mold temperature and to ensure that the material is easily separated from the mold.
• Casting Cycle: Careful planning of casting time, cooling time and inter-cycle times is critical to increase production rate while maintaining quality.

Optimization of these parameters requires a detailed engineering study of the high-pressure casting process and continuous improvements. For a perfect casting, it is essential that each of these factors is adjusted specifically to the parts to be produced and the machine used. Because even a small adjustment of each parameter can make a big difference in the quality of the final product.
