According to the design requirements of the drawings, steel with high strength, wear resistance and corrosion resistance is selected as the raw material.
According to the design requirements of the drawings, steel with high strength, wear resistance and corrosion resistance is selected as the raw material.
The chemical composition and mechanical properties of the raw materials are strictly inspected to ensure that they meet the technical requirements, and the materials are required to be tested to obtain relevant test reports such as MSDS and SGS.
The material clerk receives the materials and inspects whether the materials meet the requirements of the drawings. The technical supervisor formulates the processing procedures according to the drawings and designs and manufactures suitable fixtures.
After the above preparations, the technical supervisor begins to adjust the machine. After the parts are processed, the first piece is inspected. The quality supervisor confirms that the first piece is qualified before mass production. During the mass production process, random inspections should be carried out to avoid quality problems of parts due to other factors such as the wear of the knife particles and the failure to replace them in time.
The first is the preparation work, which requires the preparation of the required tools and materials, including spare spray guns and nozzles, paint pigments, sandpaper, cleaners, primers, etc.
The second is the surface treatment of the parts. First, use sandpaper to polish the surface of the parts to remove the oxide layer and dirt on the surface and make the surface smooth. Then clean the surface with a detergent to remove residual dirt and oil stains.
The third step is primer treatment, which is to apply the primer to the surface of the parts to form a protective film. The choice of primer should be determined according to actual needs. Generally, a primer with good adhesion and corrosion resistance can be selected.
The fourth step is drying treatment, which is to put the parts coated with primer into the drying room for drying, so that the primer is cured and a solid primer film is formed. The temperature and time of drying should be adjusted according to the requirements of the primer to ensure that the primer is completely cured.
The fifth step is to spray the topcoat, which is to apply the topcoat to the surface of the primer to form a beautiful color. The choice of topcoat should be determined according to actual needs, and a topcoat with good weather resistance and corrosion resistance can be selected.
The last step is drying and curing, which is to put the parts coated with topcoat into the drying room for drying and curing, so that the topcoat can be firmly attached to the surface of the parts and have good weather resistance and corrosion resistance.
The quality inspection process should start with raw materials, then the mechanical production process, and finally the final inspection of the finished product. Inspection is required at every stage of the production process to ensure that there are no quality problems with the product during the production process.
