What Is Stamping & Types of Metal Stamping

Metal stamping is a manufacturing process used to shape flat sheet metal with special dies and punches. The metal stamping techniques generally include blanking, bending, flanging, piercing, punching, embossing, coining, and stretching.

Yijin provides various types of metal stamping services for your custom needs, including four-slide metal stamping, in-die tapping, and press monitoring.

Progressive stamping is required to produce metal parts with complex geometries. Send us a quick message to discuss with us your metal stamping part design and get professional manufacturing advice.

Metal Stamping Parts Applications

Metal stamping parts can be used in a variety of fields including the aerospace, automobile, shipbuilding, machinery, and chemical industry. The metal-stamped parts are commonly seen in the following applications:

Electrical Appliances

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.

Vehicle Accessories

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 desired specifications after human or mechanical stamping. Welding or progressive stamping can be applied afterward to produce more complex and durable metal stamping machine parts.

Having a good understanding of geometric knowledge is essential to process metal stamping sheets. A proper machining process can standardize different metal stamping operations (stretching, bending, buttoning, stamping, etc.) and ensure that the sheet remains with the same specifications from the beginning to the end.

Kitchen Utensils

Metal stamping parts 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 rotates 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, our metal stamping 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 stamping 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.

Aerospace Components

Some special-purpose custom metal stamping parts are used in the aerospace industry. Those aerospace stamping parts are used on rockets and space shuttles.

The shell of modern aircraft is mainly a custom sheet metal stamping part with 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.

Metal stamping technology is important for the aerospace industry since it helps achieve the strict structural standards of aircraft components with higher efficiency and reliability. Metal stamping aviation parts are difficult to produce due to their various sizes, complex shapes, special materials, and service life requirements.

Common Custom Metal Stamping Parts Materials

Metal stamping processes can be performed on a variety of materials, whether ferrous (steel, carbon steel, etc.) or non-ferrous (aluminum, copper, etc.). Find the proper materials from the list to build your custom metal stamping parts.

1. SPCC

SPCC (Cold Rolled Carbon Steel Sheets and Strips in full form) is a material grade that refers to commercial quality cold rolled steel. The surface of SPCC steel is exposed to the air and therefore easily oxidized. The humid environment will speed up the oxidation process and produce red rust. It’s suggested to use paint, electroplating, or other protective materials to protect the surface in use.

2. SECC

SECC is a galvanized stamping material that is electrolytically coated with a zinc layer on the surface of the cold-rolled sheet. SECC features mechanical properties and similar processability as ordinary cold-rolled steel sheets with superior corrosion resistance and decorative appearance.

This type of material is very popular on the market since it can make durable metal stamping parts for furniture, home appliances, and electronic products. The computer case is a typical application.

3. SGCC

SGCC refers to hot dip galvanized steel material. It’s semi-finished material after hot pickling or cold rolling. After cleaning, annealing, and immersion in the melted zinc tank (at a temperature of about 460°C), the steel sheet is plated with a zinc layer. Quenching, leveling, and special chemical treatment are applied afterward to produce SGCC materials.

SGCC material is harder than SECC material with poor ductility (avoiding deep pumping design), thicker zinc layer, and poor weldability.

4. SUS 304

SUS 304 is one of the most widely used stainless steel. It’s more corrosion and heat-resistant since it contains Ni (nickel) elements. It has good mechanical properties with no hardening phenomenon in heat treatments and no elasticity.

5. SUS 301

SUS 301 is less corrosion resistant due to its lower composition of the Cr (chromium) element. However, this material can obtain good tensile force and hardness in stamping processing with good elasticity after the cold working process. It is usually used for shrapnel springs and anti-EMI.
