Die Casting Expertise

Explore the versatility of die casting processes and equipment to meet diverse project requirements.

Hot Chamber Casting
Suitable for low - melting alloys (zinc, magnesium). The injection system immerses directly in molten metal, enabling high - speed injection/cycling. Ideal for high - volume small precision parts: electronic enclosures, lock cylinders, hardware fittings.
Cold Chamber Casting
For high - melting metals (aluminum, copper). Molten metal injects into the chamber externally, with better temperature control. Suits medium - large structural components: automotive parts, motor casings, industrial hardware.
Vacuum Die Casting
Extracts air before mold injection, reducing pores and boosting density/mechanical properties. Fits structural parts needing welding/heat treatment: automotive brackets, machined components, precision hardware.
Precision Die Casting
Focuses on tight dimensional tolerances and surface finish. Ideal for industries demanding high precision, assemblability, and aesthetics: medical devices, consumer electronics, high - end industrial fittings.

What is die Casting?

Die casting is a precision manufacturing process where molten metal is forced under high pressure into a reusable steel mold (die). This creates detailed, dimensionally accurate parts with high strength. Ideal for high – volume production, it excels at producing complex geometries and tight – tolerance components efficiently and cost – effectively.


At Keywin, we use advanced die casting machines and high-quality casting molds to produce parts from materials like aluminum, zinc, magnesium, and more—ensuring optimal results for your project.
