What does a sheet metal factory do?

The sheet metal factory processes sheet metal parts, and the salary depends on the ability. Sheet metal processing includes traditional cutting, blanking, bending and forming methods and process parameters, as well as various cold stamping mold structures and process parameters, various equipment working principles and control methods, and also includes new stamping technology and new processes. Part metal sheet processing is called sheet metal processing.

Metal sheet processing is called sheet metal processing. Specifically, for example, plates are used to make chimneys, iron barrels, fuel tanks, ventilation ducts, elbows and big and small heads, round heavens and squares, funnel shapes, etc. The main processes include shearing, bending and buckling, bending, welding, riveting, etc., which require Certain knowledge of geometry.

Sheet metal parts are thin plate hardware, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is parts whose thickness does not change during processing. The corresponding ones are casting parts, forging parts, machined parts, etc.

Commonly used materials:

1. Galvanized steel plate SECC

The base material of SECC is ordinary cold-rolled steel coils, which are degreased in the continuous electro-galvanizing production line , pickling, electroplating and various post-processing processes, it becomes an electroplated zinc product. SECC not only has the mechanical properties and similar processability of general cold-rolled steel sheets, but also has superior corrosion resistance and decorative appearance. It is highly competitive and substitutable in the markets of electronic products, home appliances and furniture. For example, SECC is commonly used in computer cases.

2. Ordinary cold-rolled plate SPCC

SPCC refers to steel ingots that are continuously rolled by a cold rolling mill into steel plate coils or sheets of required thickness. There is no protection on the surface of SPCC. It is easily oxidized when exposed to the air. Especially in humid environments, the oxidation rate accelerates and dark red rust appears. The surface must be painted, electroplated or otherwise protected during use.

3. Hot-dip galvanized steel plate SGCC

Hot-dip galvanized steel coil refers to the semi-finished product that is hot-rolled, pickled or cold-rolled. After cleaning and annealing, the immersion temperature is about The steel sheets are coated with zinc in a molten zinc bath at 460°C, and then undergo tempering, leveling and chemical treatment. SGCC material is harder than SECC material, has poorer ductility (avoid deep drawing design), thicker zinc layer, and poorer weldability.

4. Stainless steel SUS304

One of the most widely used stainless steels. Because it contains Ni (nickel), it is more corrosion-resistant and heat-resistant than steel containing Cr (chromium). , has very good mechanical properties, no heat treatment hardening phenomenon, and no elasticity.

5. Stainless steel SUS301

The content of Cr (chromium) is lower than that of SUS304, and its corrosion resistance is poor. However, it can obtain good tensile strength and hardness in stamping processing after cold working. It has good elasticity and is mostly used for springs and EMI prevention.
