Products processed through the sheet metal process are called sheet metal parts. Sheet metal is a comprehensive cold working process for metal sheets, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing, and forming. This article will tell you some information about the manufacturing process of sheet metal parts.

You will know:

Sheet metal parts manufacturing process description


l  Flat rolling a piece of metal

Flat rolling reduces the thickness of the metal as it passes through a roller. Manufacturers can make a wide variety of thicknesses for larger sheet metal. In order to achieve the desired thickness, the metal may need to pass several different rollers. The rollers are mechanically driven because they require a lot of pressure to remove the thickness from the metal. This also helps to create a piece that is consistent on the plane.


l  Deep drawing

The most popular sheet processing method is the deep drawing process. This process involves extruding the metal to reduce the thickness. A punch was used in the process. It pulls the metal radially from the punch with a certain pressure. The punch compresses the metal to a specific size, so there are many different sizes of punches. The punch will have an adjustable pressure that will change the thickness of the sheet. As the thickness of the metal decreases, the other dimensions of the metal increase. This will create a sheet metal part without losing any material.


l  Sheet forming

Sheet metal part processing also includes forming. There are two ways to form the sheet. Two common ways are to rotate and press the brakes. In the pressure braking method, the metal is run through a press. The press compresses the sheet into a V-shaped groove for bending. It can be used to bend the sheet metal part sheet to a more defined angle. This process is very close to deep drawing. When the metal is fixed, the force is applied to the metal. To properly bend the metal, the metal must be perfectly machined and can be mated with the v-groove.


l  Spinning is the manufacture of cones from sheet metal parts. The metal sheet is pressed and spun into an axisymmetric member. High-speed rotation creates a centrifugal force that helps thin and expand its radius at the same time. In order to maintain the shape of the metal, a mandrel is used. This function is very similar to the role of the V-groove in the pressure braking process.




l  Aluminum alloy castings cannot be anodized with sulfuric acid;

l  Spot welded parts can be chemically treated, but cannot be electrochemically treated ;

l  Parts with deep grooves or fine holes will not completely cover the inner surface of the parts after plating

l  All electrochemical treatments should be carried out under the condition of the part, because the chemical solution during the treatment will be trapped in the gap of the assembly and cause corrosion;

l  Thin and long tubular shapes are generally not suitable for electrochemical treatment because there will be no membrane layer on the inner surface;

l  Spraying two kinds of spray paint and powder spray, after the material is pre-treated, spray the paint onto the surface of the sheet metal workpiece with a spray gun, and the paint forms a coating on the surface of the workpiece. After drying, it plays a protective role.


In conclusion


Sheet metal part processing can produce different thicknesses and shapes through any of these processes. Knowing these processes, you can create what you need. With the right tools at the same time, you can do this better.
