What is Die Casting

Die casting involves using pressure to push the molten metal into the cavity of a mold made of metal. Then the metal fills the cavity, cools down, and forms a duplicate of this cavity, which is made according to the final part that is desired. This manufacturing process creates highly accurate, detailed metal parts with excellent surface finishes and dimensional consistency.

Types of Die Casting

Die casting can be categorized based on two aspects. The first aspect is how the metal is injected into the mold:

  • Hot Chamber Die Casting(Gooseneck Casting): Dip the gooseneck tube directly into the molten metal, and direct injection through hydraulic cylinders.
  • Cold Chamber Die Casting: The molten metal is scooped into the injection chamber by a manual/robotic arm, and the piston pushes the metal horizontally for injection

The second aspect is the metal injection pressure:

  • Low Pressure Die Casting (LPDC): 0.01~0.1 MPa
  • High Pressure Die Casting (HPDC): 40~150 MPa

How to Choose Die Casting 

If you’re not a die casting professional, choosing the right casting method can be confusing. As a professional die casting factory, we know what is holding you back, and it’s our responsibility to offer assistance.

The main consideration when choosing the right die casting methods lies in three points:

  1. Material Type
  2. Parts Size and Weight
  3. Structure Requirements

Here’s a clear selection flow we made, and you can quickly figure out the best process for your custom die casting project by following it.
