What Is Cold Chamber Die Casting

Cold Chamber Die Casting

Cold chamber die casting is the preferred manufacturing process for metals that maintain high melting points. Typically, these metals include aluminum alloys, zinc alloys, brass, and copper. The requirements for cold chamber die casting include an outside furnace and a ladle to pour the molten metal. Cold chamber die casting methods are known for producing denser metal castings.

The Cold Chamber Die Casting Process

Cold chamber die casting is ideal for metals with high melting points and corrosive properties. Compared to hot chamber die casting, cold chamber die casting solves the corrosion problem by separating the melt pot from the injector components. The process begins when molten metal is ladled from the furnace into the shot chamber through a pouring hole. Next, the plunger forces metal through the shot chamber into the die at pressures ranging from 2,000 and 20,000 psi.

Cold Chamber vs Hot Chamber Die Casting

With cold-chamber die casting, metal is first heated to achieve a molten state in a separate furnace. The molten metal is then transported to the casting machine and fed into the machine’s chamber. The machine uses a pressurized plunger to force the molten metal into the mold cavity. This separated process directly differentiates cold chamber die casting from hot chamber casting.

Cold Chamber Die Casting Advantages

Cold chamber die casting is a practical, cost-effective process that can create a broad range of shapes and components compared to other manufacturing processes. The cold chamber die casting process can create parts with long service life and may be designed to complement the visual appeal of the surrounding part. Some of the direct benefits that the cold chamber die casting process provides include:

Increased Strength & Weight – Cold chamber die-cast parts are more substantial than plastic injection moldings having the exact dimensions. Thin wall castings are more robust and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.
Dimensional Accuracy & Stability – This process produces durable and dimensionally stable parts while maintaining close tolerances and heat resistance.
High-Speed Production – The cold chamber process provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required, and thousands of identical castings can be produced before additional tooling is required.
Simplified Assembly – Cold chamber die castings provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.
Multiple Finishing Techniques – Cold chambered parts can be produced with smooth or textured surface finishes, easily plated or finished with a minimum of surface preparation.

ALUMINUM DIE CASTING

Why can the die castings produced by our company be treated with black oxide?

There are multiple reasons to use black oxide treatment for die castings, and it can provide a variety of benefits to the final product. Black oxide treatment, also known as blackening or blackening treatment, is a chemically converted coating that can be applied to a variety of metal surfaces, including die castings. Some of the reasons

Thin Wall Die Casting

What Is Thin Wall Die Casting？

Aluminum thin wall die casting is a manufacturing process that generates parts that provide superior strength-to-weight ratios when compared to parts produced through other manufacturing methods. Aluminum die thin wall casting is also an efficient and economical process that can create a nearly unlimited amount of unique product shapes and sizes for industries throughout the world. Aluminum thin walled casts are also commonly used to supplement the aesthetic appeal of its surrounding part.
