Sheet metal fabrication services can be used in a variety of fields including the aerospace, automobile, shipbuilding, machinery, and chemical industry.
The sheet metal parts are commonly seen in the following applications:
Metal stamping parts are widely used in electrical appliances such as televisions, air conditioners, washing machines, and other home appliances.
Other common applications include small household appliances such as rice cookers and kettles.
The metal stamping parts specialized for such use cases are generally made of cold-rolled steel and galvanized steel.
Automotive metal stamping parts are also popular on the market. Precision stamping parts are often used on vehicle accessories.
Most of the automotive body panels and structures are made by sheet metal stamping where common operations include shearing, punching, cutting, and folding.
The metal sheet will be shaped to the desired specifications after human or mechanical stamping.
Welding or progressive stamping can be applied afterward to produce more complex and durable sheet metal parts.
Having a good understanding of geometric knowledge is essential to process metal stamping sheets.
A proper machining process can standardize different sheet metal processes (stretching, bending, buttoning, stamping, etc.) and ensure that the sheet remains with the same specifications from the beginning to the end.

Sheet metal products are usually used to create pots and pans in our daily life, which is realized through either stamping or spinning.
Stamping uses a specialized mold to form the desired shape directly.
Spinning requires the metal plate to be fixed on a lathe and rotated while a mold is applied to bend the metal.
While spinning can be used to produce round pots, it’s better for making axisymmetric hollow revolving bodies such as circles and cones.
The sheet metal stamping parts for kitchen utensils should be produced with selected materials that can meet the strict standards for sanitation and fire protection.
At YIJIN Hardware, our custom sheet metal parts for freezers, refrigerators, wine cabinets, and beverage cabinets are made of Q235 cold plates (0.6mm – 1.0 mm) and powered after forming.
The rear plates and bottom plates are galvanized (0.6mm – 0.8mm) and the inner tank is made of 0.5 mm embossed aluminum stamping materials.
The pure water machine, ice machine, water boiler, and coffee machine are mostly within 0.8 mm – 1.0 mm with powder sprayed after forming.
The special parts in contact with water vapor or experiencing large temperature differences are made of galvanized sheets (or 201 stainless steel) and powder sprayed after forming.
The stainless steel sheet metal plate is used for the touchable front part to avoid any fingerprints.
In terms of the ice machines, the water heater table is made of 202 stainless steel, the decoration is made of a 6063-T5 aluminum alloy strip, and the water tank and pipes are made of 304 food-grade stainless steel.
Some special-purpose custom sheet metal parts are used in the aerospace industry.
Those aerospace sheet metal parts are used on rockets and space shuttles.
The shell of modern aircraft is mainly a custom sheet metal stamping part with a riveted structure.
The sheet metal parts account for about 50% of all aircraft components, while custom sheet metal stamping operation accounts for 65% of the entire aircraft manufacturing process.
Sheet metal technology is important for the aerospace industry since it helps achieve the strict structural standards of aircraft components with higher efficiency and reliability.
Sheet metal aviation parts are difficult to produce due to their various sizes, complex shapes, special materials, and service life requirements.
