What is Metal Stamping?
Metal stamping involves placing a metal blank or coil into a stamping machine, and then tools and die surfaces form the metal into a net shape. Metal stamping includes a series of metal sheet forming processes, such as punching, blanking, embossing, bending, flanging, stamping, etc. using a machine or punch.Metal stamping is a cost-effective method of forming metal partswith a variety of properties, including strength, durability, wear resistance, excellent electrical conductivity and stability.
How Does the Metal Stamping Process Work?
The metal stamping process is a process that applies force to the metal material through a mold to cause plastic deformation to obtain the desired shape and size.Here are the seven steps of the metal stamping process:
Step 1: Design the mold and make a prototype
First, based on the size, shape, material and other factors of the product, the structure and size of the mold are determined through calculation and simulation. The design of the mold is the basis of the stamping process, which determines the shape and quality of the final product. Then based on the designed mold drawings, the actual mold prototype is produced for subsequent stamping production.
Step 2: Cut the Metal Blank
Firstselect metal materials suitable for stamping, such as steel plates, aluminum plates, etc. Next, the raw metal sheets or strips are cut to the required size for subsequent processing. This step is usually done using a tool such as a cutter or scissors
Step 3: Press the metal into desired shape
Put the cut metal blank into the feeding device of the stamping machine, and feed the metal into the mold through the feeding device. The pressure of the punch then causes the metal to be shaped by punches and dies on the mold. This step is the core of the stamping process. Through the precise design of the mold and the precise control of thestamping machine, metal parts of the required shape and size can be obtained.
Step 4: Trim excess material
Stamped parts usually need to be trimmedand shaped to remove burrs, cracks and other defects generated during the stamping process. This step can be done using equipment such as dressing tools or grinders.
Step 5: Heat Treat Parts (If Needed)
Depending on the material and performance requirements of the part, heat treatment, such as quenching, tempering, etc., may be required. Heat treatment can improve the hardness, wear resistance and corrosion resistance of parts to meet specific usage requirements.
Step 6: Surface Preparation or Coating
In order to improve the anti-corrosion performance or aesthetics of parts,surface treatment may be required, such as electroplating, spray painting, coating, etc.
Step 7: Quality Control and Inspection
After the stamping production is completed, the quality of the parts is comprehensively inspected to ensure that the size, surface quality and physical properties of the parts meet the design requirements. According to different quality conditions, corresponding improvement measures are taken toimprove the efficiency and quality of the stamping process.

What Are the Different Types of Stamping Processes?
1.Blanking
A basic metal stamped process that uses a mold to separate materials, which can be directly made into flat parts or prepare blanks for other stamping processes such as bending, drawing, etc. Blanking is widely used in industrial sectors such as automobiles, household appliances, electronics, instrumentation, machinery, railways, communications, chemicals, light industry, textiles, and aerospace.
2.Punching
Punching is the application of pressure to a metal plate through a specially designed mold to form a hole of the desired shape. It is often used to manufacture through holes or specific functional holes on parts to produce parts with various hole shapes, such as ventilation holes. , bracket or panel. Metals with low brittleness and moderate hardness are suitable for stamping metal to avoid cracks during the stamping process.
3.Bending
Bending refers to the process of bending a metal plate into a desired shape or angle through a mold. This process applies bending force to the metal plate, causing the metal plate to bend and deform under the action of the mold. Bending is one of the common processes in metal stamping. It is widely used to manufacture various parts and products, such as boxes, shells, brackets, etc., to provide the required shape and structure for metal products.
4.Stretch
Also called drawing or calendering, it is a stamping processing method that uses a die to turn the flat blank obtained after punching into an open hollow part. Can be made into cylindrical, stepped, conical, spherical, box-shaped and other irregular-shaped thin-walled parts.
5.Imprint
Imprinting is the creation of metallic stamp, patterns, or textures on the surface of hardware. For example, add decorative features, logos, metal stamps,or textures to components commonly found in coins and jewelry.
6.Perforation
One of the most basic forms ofmetal stamping, a machining tool is used to punch holes in a metal plate to create multiple small hollow areas. The punched material produced during the entire machining process is discarded.
7.Flange
It is a plastic processing method that bends the edge of a thin plate blank or the material in the narrow area of the edge of a pre-made hole on the blank into a vertical edge along a curve or straight line. It is mainly used to strengthen the edges of parts, remove trimmed edges, and make them for assembly with other parts. The connecting part.
8.Grooving
The main feature of grooving is cutting a small V-shaped notch or groove out of themetal stamper. Typically used where two pieces of metal need to interlock or join, such as creating tabs and notches for assembly.

4.How does metal stamping compare to other metal forming techniques?
Compared with metal stamping, other metal forming technologies such as forming (compression molding) have different characteristics and application scope: ①Application scope: Stamping is suitable for punching small and medium-sized or simple linear parts, while forming has a wider application range and can be manufactured Large parts such as braking systems, body structures, engine blocks and wheels. ② Advantages and Disadvantages: Stamping has the characteristics of high efficiency, high precision, and smooth surface, but it may be limited by the complexity of the parts and the selection of materials. Although molding has lower production efficiency, it can produce more complex products with special properties, such as three-dimensional curved parts and high-strength materials. ③ Process differences: Stamping uses a stamping machine as the main equipment, and uses molds to punch sheet metal or strip materials into the required shape. Molding is based on a mold, which extrudes molten liquid metal or semi-solid metal into the required shape under a certain pressure.
