For the processing of small metal parts, it is more difficult to process than the large parts. Because the current industry pays more attention to the accuracy of the parts themselves, and the energy of small metal parts processing itself should be more focused, especially some small parts need to be drilled on the edge, which may form waste products if not paid attention to, so it is based on the high difficulty. Today, Asset metal will talk about the main formation process of small metal parts processing.
The metal stamping process is generally adopted for the processing of small metal parts. Some adopt casting process, and then cut the blank. The products are generally assembled after surface treatment, and the hardware products made of plastic are extruded, injected, blown, and finished or surface treatment.
By metal punching machine and die on the plate, strip, pipe and profile to apply external force, so that the plastic deformation or separation, so as to obtain the shape and size of the workpiece (stamping parts) forming process.
stamping technology characteristics of metal:
1, can get light weight, high rigidity products.
2, good production, suitable for mass production, low cost.
3, can get the quality of uniform products.
4, high material utilization rate, shear and recovery of good.
small metal parts processing, mainly common carbon steel cold rolled steel strip, cold drawn low carbon steel wire, various specifications of copper, aluminum, light metal alloy and malleable cast iron, etc. Surface treatment materials are copper, nickel, chromium, silver and so on. In recent years, developed with all kinds of non-metallic materials made of hardware, such as ceramics, glass, rubber, plastic.
In particular, a variety of plastic hardware made using polyamides, polypropylene and other engineering plastics, such as bathroom hardware and plumbing hardware. These plastic products are not only of high quality, beautiful appearance, color and lustre, good decorative effect, and high production efficiency, low cost, can save a large number of non-ferrous metals, the application has been increasingly widespread.
Scope of application:
In the world's steel, 60 ~ 70% are sheet metal, most of which are made of small metal parts by metal stamping. Automobile body, chassis, oil tank, radiator piece, boiler drum, container shell, motor, electrical appliances of the iron core silicon steel sheet and so on are metal stamping processing. Instruments, household appliances, bicycles, office machinery, household utensils and other products, there are also a large number of stamping parts.
For small metal parts custom pieces, Asset metal has the following manufacturing processes: turning, CNC milling, cold forming, hot forming, metal stamping and stamping bending, pressing.
