The difference between sheet metal parts and stamping parts?

The technological process is as follows:

Sheet metal parts are mainly bent with sheet metal, the use of the machine is mainly bending machine, parts are relatively large, the process is generally: plate cutting (blanking) - bending - welding.

The machine used for stamping parts is the punch press. The precision of the parts should be high. Generally, the punching mold should be used to ensure the punching mold. Process: cutting plate (blanking) - punching - deburring.

The differences between sheet metal parts and stamping parts are as follows:

1. Different quantities

Sheet metal is hand plate or small batch production. Accurately speaking, it is proofing, and then the quantity is relatively small, if the mold is opened, the cost of the mold can not earn back. Stamping, is the mass production and precision requirements of things, the output is larger, it is sure to open the mold stamping.

2. Different processes

Sheet metal parts are metal sheet parts that are manually beaten by workers with simple equipment such as hammers. Characteristic is low efficiency, parts quality through manual control, not stable, but low cost, used for small batch life, or trial production stage.

Stamping parts are metal sheet parts that are stamped by die and press. It is characterized by high efficiency, parts quality controlled by mold, strong stability, but high cost, used for mass production.

3. Different procedure

Stamping parts rely on press and mold to impose external force on plate, strip, pipe and profile, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece forming processing method. Stamping and forging belong to plastic processing, collectively known as forging. The blanks for stamping are mainly hot and cold rolled steel plates and strips.

Sheet metal is a comprehensive cold working process for sheet metal, including cutting, punching/cutting/compounding, folding, welding, riveting, splicing, forming, etc. Its remarkable feature is the same thickness of the same parts. The products processed by the sheet metal process are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly.
