Applicability of common materials for precision sheet metal processing

Precision sheet metal processing generally selects suitable materials according to the characteristics of the products to be processed. Most of the products processed by sheet metal processing are qualitative, so the materials and products are also easy to correspond. Sheet metal generally uses a lot of materials. It is precisely because of the variety of metal materials and processing procedures of sheet metal that there is no accurate definition of sheet metal.


The materials commonly used in precision sheet metal processing are cold-rolled sheet, hot-rolled sheet, galvanized sheet, stainless steel, etc. The applicability is as follows:

1. Cold-rolled sheet, cold-rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet. Cold-rolled sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled sheet steel. , In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel.

2. There are many types of hot-rolled steel plates, which are used in many fields. Because of their low cost and difficulty in forming, they are mainly used for flat parts in the sheet metal processing industry.


3. Primer, epoxy zinc-rich primer used in precision sheet metal processing. The purpose of this layer of primer is to protect steel structures and steel products and prevent rust. Its coating film has good physical and chemical properties, is easy to construct, and has good matching performance. The main components are: epoxy resin, epoxy curing agent, zinc powder, anti-rust pigment, auxiliary agent and organic solvent, etc.


4. Intermediate paint, sheet metal processing products use epoxy micaceous iron intermediate paint, which is used together with epoxy zinc-rich primer as a transition layer of long-term anti-corrosion coating, and its function is to enhance the sealing and anti-corrosion of composite coating. It can also be used as an anti-corrosion and anti-rust primer. The coating film is strong and tough, has good adhesion and sealing, and is well matched with the front and rear coatings. Its components are: epoxy resin and curing agent, iron oxide and anti-rust pigment, etc.
