Product Description:
Sheet metal, a kind of processing technology, sheet metal has yet
to have a more complete definition. According to a definition in a
foreign professional journal, it can be defined as follows: Sheet
metal is for sheet metal (usually below 6mm) a comprehensive cold
working process, including shearing, punching/cutting/compounding,
folding, riveting, splicing, moulding (e.g., automobile bodywork)
and so on. Its distinctive feature is the consistent thickness of
the same part.
Sheet metal is characterised by light weight, high strength,
conductivity (able to be used for electromagnetic shielding), low
cost and good performance in mass production, and is widely used in
the fields of electronics and electrical appliances,
communications, automotive industry, medical devices, etc. For
example, sheet metal is an essential component in computer cases,
mobile phones and MP3s. As the application of sheet metal becomes
more and more widespread, the design of sheet metal parts has
become a very important part of the product development process.
Mechanical engineers must be proficient in the design of sheet
metal parts, so that the design of sheet metal meets the
functionality and appearance of the product and other requirements,
but also to make the stamping mould manufacturing simple and
low-cost.
Applications:
Sheet metal materials suitable for stamping processing are very
many, widely used in the electronic and electrical industry sheet
metal materials include:
⒈ Ordinary Cold Rolled Plate SPCC SPCC refers to the ingot through
the cold rolling mill continuous rolling into the required
thickness of steel coil or sheet. SPCC surface without any
protection, exposed to the air is very susceptible to oxidation,
especially in the humid environment oxidation speed up, the
emergence of dark red rust, the surface should be sprayed, plated,
or other protection when in use.
2,PEAK Zinc plated steel SECC SECC substrate for the general cold
rolled steel coils, in the continuous zinc plating production line
after degreasing, pickling, plating and a variety of post-treatment
processes, that is, become zinc plated products. SECC not only has
the general cold rolled steel sheet mechanical properties and
similar processability, but also has a superior corrosion
resistance and decorative appearance. In the market of electronic
products, home appliances and furniture, SECC has great
competitiveness and substitutability. For example, SECC is commonly
used in computer cases.
3,Singed stainless steel SUS301 Cr (chromium) content is lower than
SUS304, corrosion resistance is poor, but after cold working can
get very good tensile strength and hardness, elasticity is better,
more used in leaf springs and anti-EMI.
Be careful with Stainless Steel SUS304, one of the most widely used
stainless steel, because it contains Ni (nickel), so it is richer
in corrosion resistance and heat resistance than the steel
containing Cr (chromium), it has very good mechanical properties,
no hardening phenomenon of heat treatment, and it is not elastic.
