Sheet Metal Fabrication Aluminium Stainless Steel

Stainless steel sheet metal processing technology:

1. Blanking:

Select blanking, and after completion, enter the following process, according to the requirements of stainless steel sheet metal processing into the corresponding function.

2. Spraying treatment:

Stainless steel sheet metal parts in bending, riveting and other processes after the completion of surface treatment, different plate surface treatment is different, cold plate processing after the general surface plating, plating after the end of the need for spraying treatment, and the other is usually the use of vulcanization treatment, after phosphating to spray treatment. Electroplated plates require surface cleaning, degreasing, and then spraying.

3. Bending:

Stainless steel sheet metal processing in bending, according to the size of the drawings, and material thickness to determine the bending tool and slot. In order to avoid deformation caused by the collision between the product and the tool the key to the selection of the upper die, and the selection of the lower die is determined according to the thickness of the plate. In order to weld firmly, the convex point is made on the workpiece to be welded, and the convex point is in uniform contact with the plate before electric welding, to ensure that the heating of each point is consistent.

4. Assembly:

After bending and spraying to carry out the assembly process, before assembly, to tear off the protective stickers used in the original spraying, to determine the parts of the internal thread hole were not sprayed into the paint or powder, during the whole process, wear gloves, to avoid the hand dust attached to the workpiece, if found on the workpiece debris or dust, need to blow clean, in order to enter the packaging link.

5. Surface treatment:

Surface treatment is generally phosphating skin film, electroplating colorful zinc, chromate, paint, and oxidation, phosphating skin film is generally used for cold-rolled plate and electrolytic plate class, its role is mainly in the material surface on a layer of protective film, preventing oxidation. Another is to enhance the adhesion of the paint, electroplating colorful zinc is generally cold rolled plate surface treatment; Chromate and oxidation are generally used for surface treatment of aluminum plate and aluminum profile; The selection of its specific surface treatment is based on customer requirements.

6. Assembly:

Assembly is the last step in the completion of a material. If the material can not be used due to scratches, it needs to be reworked, which will waste a lot of processing hours and increase the cost of the material. Therefore, special attention should be paid to the protection of materials.

In summary, it is stainless steel sheet metal processing technology. It is worth noting that stainless steel sheet metal processing workpieces in folding, riveting, and other production and processing processes to carry out surface treatment, due to the difference in materials, the surface treatment method is also different. Under normal circumstances, the surface plating process should be carried out after the production and processing of the cold plate, and there is no need to carry out spray painting after the plating process.
