Our Precision Die Casting Services
If you have needs of custom metal parts, Qijia is a die casting service manufacturer that can help. Since 2009, we've hold our engineering team and equipment to a high standard to continually deliver strong and durable parts and prototypes. To ensure legendary quality, we operate strict die casting process that ensures that your custom requirements are being met. These are two types of die casting capabilities we provide.
Hot Chamber Die Casting
Hot chamber die casting, also known as gooseneck casting, is a considerably quick process with a typical casting cycle only 15 to 20 minutes. It allows for high volume manufacturing of comparatively complex parts.
The process is ideal for zinc alloy, lean alloys, copper and other alloys with low melting point.
Cold Chamber Die Casting
Cold chamber die casting process is an very important procedure which helps reduce the amount of heat and solve the corrosion problem in machine's plunder and related components.
The process is primarily used for alloys with high melting points, like aluminum, magnesium, some copper, and ferrous alloys.
