Die Casting


Die casting is a manufacturing process in which molten metal is poured or forced into steel molds. The molds—also known as tools or dies—are created using steel and are specially designed for each project. This allows each component to be created with accuracy and repeatability. Aluminum, zinc, and magnesium are the most commonly used die casting alloys.

Die Casting Advantages

Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. When you cast a part, you can create complex net shapes, including external threads and complex internal features with minimal draft angles—minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.

Other benefits include:

  • • Variable wall thicknesses
  • Tighter tolerances
  • Fewer steps from raw material to finished part
  • Fast production cycle times
  • Reduction in material scrap
  • Long tool life, especially for zinc and magnesium


The die casting process can be further divided into two different categories:

  • Hot Chamber Die Casting
  • Cold Chamber Die Casting


Unison Tek is very good at manufacturing turning parts and milling parts, we still cooperates with some sister companies, some one die casting factory, there are much experienced engineers to work to meet high quality metal parts for customers.

Principle of Die Casting

The principle of die-casting:

Casting molten metal such as aluminum, zinc, magnesium, copper, etc. with good condensing property, into the mold of high-temperature resistant steel with high-speed mechanical properties, using the casting method of rapid solidification of steel mold at lower temperature.

The characteristics of the die casting method are:

high productivity, excellent dimensional accuracy, low post-processing, smooth casting surface, high mechanical strength, and excellent properties such as thin-walled castings.
