Dongguan precision electronics co. , LTD. After more than 30 years of study in the field of stamping processing, now has become many fortune 500 companies to reach a long-term cooperation, the company all production equipment, testing equipment are imported from Japan, mainly providing precision stamping parts, terminal stamping, metal shrapnel processing, etc.
Metal shell has a very wide range of applications, especially in using the most mechanical and electrical industry, mainly related to the industry, including electronics, electrical appliances, advertising, IT, communication, automobile, construction, furniture, bags, craft gifts, sports equipment, clothing, daily, outdoor, etc.
Shrapnel making use of materials generally have: stainless steel, copper, aluminum, carbon steel, manganese, etc.
Go through heat treatment.
You know what is the effect of heat treatment?
Heat treatment can improve the surface hardness, abrasion resistance and contact fatigue strength, improve the core of strong toughness.
Metal shrapnel heat treatment can be divided into surface quenching tempering heat treatment and chemical heat treatment of the two.
Surface quenching tempering heat treatment usually use induction heating or heating of the flame.
And chemical heat treatment is to make the workpiece surface infiltration of one or more of the following elements of atoms, which changes the surface chemical composition, microstructure and mechanical properties.
Is the main technical parameters of surface hardness, local hardness and effective hardening layer depth.
So the metal shrapnel processing to heat treatment.
Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public.
