Stainless steel sheet metal processing refers to the processing of stainless steel and other metal sheets, such as cutting, bending, and grooving. Whether we are in life or in industrial applications, we can often see stainless steel sheet metal processing products, so Its field of use is very broad. However, although many friends are no strangers to stainless steel sheet metal processing products, they know very little about its processing procedures. So what is the process of stainless steel sheet metal processing?
Process of stainless steel sheet metal processing:
Sheet metal processing drawing planning –> laser processing or (NC stamping) –> bending –> welding forming –> electrostatic powder spraying or (liquid paint) –> packaging and shipping
- Sheet metal processing drawing planning
In the early stage of stainless steel sheet metal processing, it is necessary to understand the needs of customers. When receiving the order information and product requirements of the product, it is necessary to first form an idea in the brain, especially the appearance and molding of the product, and then make drawings, combined with the product requirements, and intuitively reflect On the drawings, and indicate various parameters, if there are uncertain or uncertain parts of the demand to communicate with the customer in a timely manner, when the drawings are confirmed, they will be delivered to the engineering department, and then the engineering department will delegate the requirements to the construction workers and become technicians. After the review is over, it can be signed and sent to the workshop.
- Laser processing or (CNC stamping)
Laser processing has no tool restrictions and has a flat cross-section, which is suitable for the processing of special-shaped workpieces, but it takes a long time to process small workpieces. A workbench is placed next to the CNC and laser, which is convenient for the sheet material to be placed on the machine for processing and reduces the workload of lifting the sheet.
When the stainless steel sheet metal is processed and bent, the bending direction and standard should be confirmed by samples. If there is too much material or lack of material, it should be adjusted in time. After the sample is confirmed, mass production can be carried out, and then the molds can be replaced during production. And workmanship to be re-inspected. The quality inspection of the processed stainless steel sheet metal parts is carried out, the standard of the sheet metal parts is checked by sampling, and then the appearance is checked, the unqualified products are returned to the furnace, and the inspection report form is filled out.
- Welding and forming
In order to ensure the firmness of stainless steel sheet metal processing during welding, it is necessary to make bumps on the workpiece. The bumps are evenly contacted with the plate before electric welding to ensure that each welding point is heated uniformly.
- Electrostatic powder or (liquid paint)
The surface treatment of stainless steel sheet metal processing generally includes phosphating film, electroplating colorful zinc, chromate, baking paint, oxidation, etc. The phosphating film is generally used for cold-rolled sheets and electrolytic sheets, and its function is mainly to plated on the material surface. A protective film is applied to prevent oxidation. The selection of specific surface treatment methods is determined according to customer requirements.
- Packing and shipping
Before assembly, tear off the protective sticker used in the original spraying to make sure that no paint or powder has been spilled into the threaded holes of the parts. If there is debris or dust on it, it needs to be blown clean before entering the packaging process.
