What are the common fabrication methods of automotive sheet metal parts?
The process of changing the shape of metal sheets using various equipment is called sheet metal fabrication. The main processes are shearing, bending, welding, riveting, etc. Auto parts can also be processed by stamping, bending, stretching and other means, and we can use it to perform a series of treatments on metals.
Common handling:
1. Metal marking
Direct part marking is a range of techniques for permanent marking on metal for traceability of parts, industrial part labeling, decoration or any other purpose. Marking can be achieved by a variety of techniques including engraving, embossing, die casting, stamping, etching and grinding.
2. Metal engraving
Engraving is a technique mainly used to engrave patterns, words, drawings or codes on metal surfaces to obtain products with permanent markings, or to use engraved metal to print engravings on paper. Engraving mainly uses two technical means: laser and mechanical engraving. Mechanical engraving can be done by hand, or by more reliable pantograph or sheet metal machining.
Metal engraving technology can be used for: personalized jewelry, fine art, photopolymer laser imaging, industrial marking technology, engraving sports competition trophies, printing plate making, etc.
3. Metal Stamping
Metal stamping is not a subtractive machining process. It is the use of molds to fold metal sheets into various shapes. Household utensils that we come into contact with, such as pans, spoons, cooking pots and plates, are stamped. Punch presses are also used to make ceiling materials, medical equipment, machine parts and even coins. Its products are widely used in medical, electronic, electrical, automotive, military, HVAC, pharmaceutical, commercial and machinery manufacturing industries.
4. Metal Grinding
Grinding is the physical grinding of a workpiece with a cutting tool (abrasive), typically for trimming rough edges, deburring, grinding welds, removing chips, producing sharp edges, or giving metal parts a unique finished appearance. Typically, grinding is a subsequent operation after a part has been engraved, stamped, etched or any other form of automotive sheet metal fabrication.
