What are the differences between Sheet Metal Processing and hardware processing? Let‘s briefly understand:

Metal is ubiquitous in existence, such as common knives, fixtures, general hardware accessories, bearings, locks, molds, machinery and equipment, fasteners, screwdrivers, plumbing hardware, etc. are all called finished metal products. Metal manufacturing is a process of processing metal materials (gold, silver, copper, iron, tin) into items, parts, and components, including large parts such as bridges and ships. It is used to define the boundaries of science, industry, art, crafts, and other differences.

Sheet metal processing is for sheet metal, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is parts with a fixed thickness during processing. Sheet metal processing usually involves exciting, punching, folding, welding and splicing (such as car bodies). Among them, sheet metal processing technology should be supported by related equipment such as bending machines, welding processing, grinding processes, etc., so that sheet metal processing can be completed through different processes and forming processes to meet customer needs.
