Sheet metal parts are mainly bent with thin plates, and the machines used are mainly laser cutting machines and bending machines. The parts are also relatively large. The general process is: shearing (blanking)-bending-welding-surface treatment.
The machine used for stamping parts is a punching machine, and of course the precision of the parts is very much higher. Generally, a punching die is used to ensure it. Process involved are shearing (blanking)-punching-deburring.
But how do we decide whether to use stamping or sheet metal, and what is their difference?
1. The quantity is different
Sheet metal is a prototype or small batch production. To be precise, it is proofing, and the quantity is relatively small. If the mold is opened, the cost of the mold will not be earned. Stamping refers to mass production and precision requirements. If the output is relatively large, it must be stamped on the mold.
2. Different processes
Sheet metal parts are metal sheet parts that are manually beaten by workers with simple equipment such as hammers. It is characterized by low efficiency. The quality of parts is controlled manually, which is not stable enough, but the cost is low. It is used for small batch production or trial production stage.
Stamping parts are sheet metal parts stamped by die and press. It is characterized by high efficiency, the quality of the parts is controlled by the mold, the stability is strong, but the cost is high, and it is used for mass production.
For regular brackets or frames, they can be done by either sheet metal and stamping, mostly up tp the potential quantity.
