Equipment Sheet Metal Enclosures

What is the production and processing material of sheet metal case shells?

General cold-rolled sheet SPCC

SPCC refers to the continuous cold rolling of steel castings into hot-rolled strips or thick steel plates of the desired thickness by a cold rolling mill. SPCC has no surface maintenance. When exposed to the air, it is very easily oxidized, especially in cold and wet conditions, the air oxidation rate is accelerated and deep red rust occurs. Metal plate car chassis shell surface in the production process should carry out spraying, electroplating process, or other maintenance.

Two, stainless steel plate SUS301

Chromium content is less than SUS304, with poor corrosion resistance. But after cold drawing, better tensile strength and strength can be obtained in the whole process of die casting, and it has better ductility. Suitable for spring plate torsion spring and interference signal maintenance.

Hot-dip galvanized coil steel is a kind of semi-finished coil steel processed by hot drawing, pickling passivation, or hot rolling. After cleaning and quenching, the thick steel plate was permeated into a zinc solution at 460℃ and coated with a zinc layer, followed by heat treatment, quenching, and correction of organic chemistry solution. SGCC material is harder than SECCO material, has less plastic (prevents deep drawing design scheme), thick zinc layer, and poor malleability.

Four, stainless steel plate SUS304

Stainless steel plate is the most commonly used kind of steel, because of its nickel content, corrosion resistance and temperature resistance are better than manganese steel. With good physical properties, no heat treatment process hardbase, inelastic.

Five, galvanized sheet

After deoiling, pickling passivation, electroplating, and various post-processing processes are carried out on the continuous electric galvanizing production line, the high precision sheet metal chassis shell becomes phosphating products. SECC not only has the physical properties and similar production characteristics of ordinary cold-rolled sheets but also has good corrosion resistance and art Deco appearance. Sheet metal case processing in electronic equipment, electrical products, and the home furnishing market has extreme competitiveness and substitutability.
