Punching, Blanking, Trimming, Cutting

- Jun 15, 2018 -

(1) Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of part products, facilitates mechanization and automation, and has higher production efficiency. At the same time, stamping production can not only strive to produce less scrap and no waste, but even under certain circumstances The remaining material can also be fully utilized.

(2) The operation process is convenient and does not require the operator to have a higher level of skill.

(3) Stamped parts generally do not need to be machined again and have a high dimensional accuracy.

(4) stamping parts have better interchangeability. Stamping process stability is better, the same batch of stampings. Can be used interchangeably without affecting assembly and product performance.

(5) Since the sheet material used for stampings is made of a material, its surface quality is good, providing convenient conditions for subsequent surface treatment processes (such as electroplating and painting).

(6) Stamping can obtain high-strength, high-rigidity, and light-weight parts.

(7) Stampings produced in batch with molds are inexpensive.

(8) Stamping can produce complex parts that are difficult to machine with other metal processing methods.
Stamping process


The stamping process can be divided into four basic processes:

Punching: The stamping process (including punching, blanking, trimming, cutting, etc.) to separate sheets.
Bending: A stamping process that bends the sheet material along a bending line to a certain angle and shape.

Deep drawing: The punching process in which the flat sheet material is changed into various open hollow parts or the shape and size of the hollow part are further changed.

Partial Forming: The stamping process (including flanging, bulging, leveling and shaping processes, etc.) to change the shape of blanks or stampings using various localized deformations of different properties.
