Our box for circuit board is made of galvanized sheet and the surface is not treated. the production process throughout wear gloves to ensure that the surface of the product is flawless and free of stains. The middle molding is a simple molding mold making, which saves costs, reduces mold costs, and reduces production costs. For all products, we will consider reducing the production cost for our customers, while ensuring the quality of our products and meeting every detail of our customers.

There are two type of stamping

The stamping process can be roughly divided into two categories: separation process and forming process (also divided into bending, deep drawing, and forming).

The separation process is to separate the stamping parts and the blanks along a certain contour line in the stamping process, and the quality of the separated sections of the stamping parts also meets certain requirements;

The forming process is to plastically deform the stamped blank without breaking, and convert it into the desired finished shape, and also meet the dimensional tolerance requirements.

According to the temperature conditions at the time of stamping, there are two methods of cold stamping and hot stamping. This depends on the strength, plasticity, thickness, degree of deformation, and equipment capabilities of the material, as well as the original heat treatment state and end-use conditions of the material.

Classification of precision metal stamping:

Auto parts: mainly include automobile structural parts, automobile functional parts, automobile lathe parts, automobile relays, etc.
