What is the difference between stamping and die casting?

There are significant differences between stamping and die casting in many aspects, including:

Principle:

Stamping is to place metal plates, strips, pipes, or profiles in a mold, and apply external force to them through a press and mold to cause plastic deformation or separation, thereby obtaining workpieces of the required shape and size.
Die casting involves injecting molten metal into a mold and forming it under high pressure.

Processing methods:

Stamping is mainly processed through pressing, cutting, bending, and other steps.
Die casting requires melting, injection, compaction, and other steps.

Scope of application:

Stamping is mainly used to produce simple parts and is commonly used in the electronics industry, automobile manufacturing, kitchen appliances, and other fields.
Die casting can produce more complex and precise parts, and is mainly used in mechanical engineering, aerospace, energy equipment, and other fields.

Materials used:

Stamping parts usually use metal materials such as plates and strips as raw materials.
Die castings mostly use non-ferrous metals such as aluminum alloys and magnesium alloys or metal materials such as steel.

Product performance:

Stamping parts have high strength and hardness, high surface finish, and high dimensional accuracy and shape accuracy.
Die castings have good toughness and plasticity, but have high surface roughness and relatively low dimensional accuracy and shape accuracy.

Productivity:

Stamping parts have high production efficiency and are suitable for mass production.
The production cycle of die castings is relatively long and the production efficiency is low.

Molds and Equipment:

The mold used for stamping is called a stamping die and needs to be used with stamping equipment.
Die casting requires the use of a die-casting machine that can withstand high pressure and a specialized die-casting mold.

When choosing stamping or die-casting as a manufacturing process, comprehensive considerations need to be made based on specific product requirements and production processes to achieve product results.
