Custom-cut sheet metal parts are the core of many industries such as automobiles, aerospace, electronics, and medical devices. Such components are usually customized to meet the needs of the industry. Therefore, they provide accurate sizes, show specific designs, and provide high performance. This guide will introduce the custom-cut sheet metal process in detail.

What are the ways to custom-cut sheet metal?
1· Flame cutting:
Flame cutting is mainly used to process a thick metal plate when cutting metal plates. This processing method has a large thermal deformation and width of the seams, which will cause a certain degree of material waste, and it will not be processed too fast. It can be roughly processed by sheet metal.
2· Plasma cutting:
Plasma cutting is a processing method of molting and evaporating the local metal locally in the metal gap at the workpiece gap, and the melting metal is removed through the momentum of the high-speed plasma to form a gap. In fact, the use of plasma machinery and flame processing have some similarities. Although they are heated, they have great advantages in accuracy.
3· Line cutting:
The full name of the wire cutting is cutting and processing, which belongs to the category of electricity. Depending on the speed of the wire, it can be divided into fast-moving wire cutting, cutting the wire wire cut, and slowly walking the wire cutting. The cutting speed of the wire wire is 6 ~ 12m/s. The cutting of the Silk Electric Spark is a new technology that has been developed in recent years. It has realized frequency conversion and multiple cutting functions on the basis of online cutting. The speed of the wire when cutting is 0.2m/s, and the electrode wire movement is low-speed, so the cutting accuracy is very high.
4· High-pressure water cutting:
High-pressure water cutting is also a common method for sheet metal processing. It uses a high-speed water-based silicon carbide to machine the metal plate, which can have many processing materials and high processing thickness. It also has a good effect on explosive materials such as ceramics and glass. There are also advantages to cutting copper and aluminum materials. The disadvantage is that the water cutting is slow and not environmentally friendly.
5· Laser cutting:
Laser cutting is the use of a high-power density focused laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates, or reaches the ignition point, while being blown off the melted material by the high-speed airflow coaxial with the beam, thus cutting the workpiece, which is a thermal cutting.
There is no deformation during laser cutting, non-knife-free wear, and good material adaptability. The use of laser processing boards can complete a precision cutting, the quality is good, the operation is simple, and the pollution is small, which can improve the material utilization rate during cutting.
Merchants can choose the appropriate cutting method according to the product requirements.
Custom-cut sheet metal operation steps
Step 1: Measurement and mark
1.1 Use a pencil or marking tool to measure and mark on the sheet metal surface. According to the size and shape of the need, make a clear marking line on the sheet metal to facilitate subsequent cutting.
1.2 Make sure the measurement is accurate and use a ruler or tool for assistance. A proper edge is left around the area where you need to cut to avoid accidental cutting.
Step 2: Select the right cutting tool
Select the appropriate cutting tool according to the thickness and shape of the sheet metal. Common rice cutting tools include shear, cutting knife, and electric cutting tools. Make sure the selected tools can meet the cutting requirements and have a small degree of wear, so as not to affect the cutting quality.
Step 3: cutting operation
3.1 Place the sheet metal on a flat workbench and keep it stable. Make sure that no debris, dust, etc. are interfered with cutting work.
3.2 According to the direction of the line, the cutting tools are aimed at the rice and ensure that the cutting tool and the surface of the rice net are kept vertical.
3.3 Cut the cut operation with appropriate strength and speed to maintain a stable push-pull action to avoid being too rapid or slow. According to the thickness of the rice and the characteristics of the cutting tool, adjust the cutting strength and speed to achieve a better cutting effect.
3.4 During the cutting process, especially when cutting long rice, pay attention to maintaining stable support and a smooth operation rhythm to ensure that the cut lines are straight and accurate.
Precautions for custom-cut sheet metal
- When performing sheet metal cutting operations, be sure to wear safety protection equipment, such as gloves, goggles, etc. to avoid accidental damage during cutting.
- Pay attention to the sharpness of the knife when cutting sheet metals. The blunt knife will increase the difficulty and strength of the cutting, and it will also reduce the cutting quality.
- If you need to perform subsequent processing operations such as bending on the sheet metal, the straightness and accuracy of cutting lines are particularly important, so you need to carefully measure and mark thembefore cutting.
