Seven Steps in Precision Sheet Metal Fabrication
1. Punching
Punching involves punching out the product’s pre-formed shape according to the drawing using a press brake to create the desired hole locations and dimensions.
2. Bending
Bending involves bending the unformed product to the desired shape and dimensions using a press brake, ensuring the product meets the customer’s functional requirements.
3. Stamping
Stamping involves using the force of a punch to press a nail-shaped part onto a workpiece, securing it and facilitating installation.
4. Welding
Welding involves using heat treatment to firmly fuse two parts or corners together, creating the illusion that the two parts were originally joined.
5. Polishing
Polishing involves removing any sharp edges or weld slag from punching or welding, using a high-speed grinding wheel to smooth the surface and achieve the desired appearance. 6. Spraying
The spraying process involves placing the product in an acid bath to remove the surface acid, creating a chemical reaction. A colored powder is then sprayed on the surface to create a new finish.
7. Packaging
Packaging involves placing the finished product into bags or cartons to prevent surface damage and defects during transportation.
