Cold Chamber Die Casting | Precision Aluminum

1.Cold Chamber Die Casting Services | Welleshaft

Cold chamber die casting is ideal for shaping large and complex metal parts, particularly with high-melting alloys like aluminum die casting alloys, magnesium castingund zinc die cast metals. Welleshaft brings years of expertise in delivering die casting solutions for industries such as automotive diecasting, aerospace, electronics, and medical fields. With our cutting-edge technology and deep industry knowledge, we ensure precise and high-quality results.

2.What Is Cold Chamber Die Casting?

Cold chamber die casting works by injecting molten metal into a separate shot chamber before forcing it into the mold under high pressure. Unlike other methods, this technique is perfect for diecast metal components like aluminum die castings und magnesium die casting. Furthermore, the die casting machine uses an external furnace, which helps regulate the temperature more effectively, reducing defects like porosity.

This process works best for:

• Die cast aluminum alloys such as A380 und ADC12.
• Magnesium casting for aerospace components.
• Zinc die casting components for precise electronic parts.

By separating the melting stage, Welleshaft ensures that the casting surface is controlled, thus extending die life and minimizing defects in the final product.

3.Why Choose Cold Chamber Die Casting from Welleshaft?

Cold chamber die casting makes sense when you need high precision and reliability. For instance, we provide:

• High-volume aluminum die castings such as aluminum casting die for automotive parts.
• Custom aluminum components for EV platforms, using A380 aluminum oder ADC12 material.
• Slide casting for creating complex shapes und thin-walled structures.
