The Power of High-Pressure Die Casting

High-Pressure Die Casting is a highly efficient and versatile manufacturing process used for producing metal parts by forcing molten metal under high pressure into a steel mold cavity (die). This method is particularly well-suited for non-ferrous metals like aluminium, zinc, and magnesium, and is a cornerstone of modern mass production.

The HPDC process, a core offering at Sejasmi, typically involves:

1. Die Preparation: The steel dies (molds) are precisely machined to the desired part shape, preheated, and lubricated.
2. Molten Metal Injection: Molten aluminium is rapidly injected into the die cavity under extreme pressure (ranging from 10 to 175 MPa or more). This high pressure ensures that the metal completely fills even the most intricate features of the die.
3. Solidification: The metal quickly solidifies under pressure, ensuring a dense microstructure and excellent surface integrity.
4. Ejection: Once solidified, the die opens, and the cast part is automatically ejected.
5. Trimming & Finishing: Excess metal (flash, gates, runners) is trimmed, and parts may undergo further processes like shot blasting, machining, or heat treatment of aluminium alloy to achieve final specifications.
