Sheet metal fabrication pays an important role in electronic industry. From big parts like metal cabinet, chassis, housing, brackets to small parts like terminal, USB connectors, contact chip etc, we can see sheet metal parts everywhere. The consumer electronics industry has witnessed tremendous growth in recent years and precision sheet metal fabrication has provided a guarantee for the updating and replacement of electronic industry products.
Consumers are now pursuing smaller, thinner, and lower energy consuming electronic devices, which can be achieved through precision sheet metal production. As a professional sheet metal fabrication factory, we uses advanced materials, machines, and processes to manufacture micro electronic products and also big electronic parts shell, which not only ensure the firmness, accuracy, and precision of the products, but also enhance the aesthetics of electronic products through powder coating, anodizing, electroplating, and other surface treatment.
At Shanghai Yixing Technology, we have complete range of equipment like flat laser cutting machine, 3D laser cutting machine, hydraulic press, deep drawing machine, punching machine, shearing machine, CNC bending and welding machines to combine all the sheet metal fabrications like metal bending, metal stamping, progressive die stamping, welding and also surface treatment for one stop sourcing.
Some electronic components can be very small in size but complex in structure. Our facility has been very professional in progressive die stamping for these small components. Progressive die stamping is ideal for big volume production and at the same time ensures cost effective and great accuracy.
First of all, we select the correct material grade based on the drawing materials. We will strictly control the inspection of incoming materials and material storage. We will require the mill factory to provide raw material certificates and ask a third party to test the chemical composition of the materials. Our own inspectors will conduct visual inspection (mainly looking for surface defects, scratches and rust), thickness and size inspection of raw materials.
We will then evaluate the production process based on the design of the customer's drawings, which is generally divided into the following steps:
1. Cutting
We can use laser cutting, plasma cutting, flame cutting and water cutting, etc. for blanking. Cutting is usually the first step in sheet metal production.
2. Punching
According to the design requirements, punch holes in the cut metal plate to facilitate subsequent bending and forming.
3. Bending and forming
Bending and forming the punched metal plate, we usually use equipment such as bending machines and stamping machines.
4. Welding
For sheet metal parts that need to be joined together, welding is most common assembly method. Commonly used welding methods include argon arc welding, laser welding, etc.
5. Surface treatment
The surface of sheet metal parts needs to be treated to enhance its corrosion resistance, wear resistance and aesthetics, such as powder coating, chrome plating, anodization, electroplating and other treatments.
