Characteristics of metal manufacturing

Metal fabrication (metal technology), is a metal material processing into goods, parts, components, technology, and includes bridges, ferries and other large parts, and even the tiny components of engines, jewelry, watches. It is widely used in science, industry, arts, crafts and other fields.

Some of the specialized metal fabrication methods include brazing, shearing, forming, extrusion, forging, heat treatment, powder coating, punching, casting, spinning, and chipping to name a few. Some of the higher level specializations include electrical, prototyping, machine design, and hydraulics.

Characteristics of metal manufacturing

(1) on the adaptability of casting shapes and sizes. It can produce a variety of shapes and sizes of rough, especially suitable for the manufacture of parts with complex inner cavity.

(2) the adaptability of the material. Can be adapted to most metal forming, not suitable for forging and welding materials, casting has its unique advantages.

(3) low casting cost. This is due to the casting material is abundant, casting shapes close to the parts, reduces the amount of machining to reduce casting cost.

Casting is a blank one of the most important ways, such as by weight, 60%~80%, car 50%~60% used in the machine tool castings. But as casting process links, easy to produce a variety of casting defects, and General casting of coarse grain size, mechanical properties than forging. Castings are generally not suitable for making the important parts of the complex forces and force, and is mainly used by force or by simple static loading (particularly suited to compression stress) parts, such as cabinet, bed, frame, frame, etc.

Fabricated metal products industry-wide

Metal products including: tools, fixtures, General hardware, bearings, locks, tooling, machinery and equipment, fasteners, metal, screw driver, instruments, plumbing hardware, hardware.
