Material selection:
According to the design requirements of the drawings, select aluminum alloy with low density and high strength as the raw material.
Material inspection:
Strict inspections have been conducted on the chemical composition and mechanical properties of raw materials to ensure compliance with technical requirements, and materials are required to undergo testing to obtain MSDS, SGS, and other relevant testing reports.
Hair embryo production:
Aluminum bars are melted and extruded to obtain aluminum profiles with the desired cross-sectional shape. And inspect the produced profiles.
machining:
The material handler receives materials and inspects whether they meet the requirements of the drawings. The technical supervisor develops processing procedures based on the drawings and designs and manufactures suitable fixtures. After the above preparations are made, the technical supervisor begins to adjust the machine. After the parts are processed, the first piece is inspected, and the quality supervisor confirms that the first piece is qualified before mass production can be carried out. Sampling inspection should be conducted during the mass production process to avoid quality problems caused by factors such as tool wear and failure to replace parts in a timely manner.
Polishing:
Use polishing tools to modify and process the surface of parts to achieve the desired glossiness. When polishing, the high-speed rotating polishing wheel is pressed against the workpiece, causing the abrasive to roll and micro cut the surface of the workpiece, thereby obtaining a bright machined surface.
Sandblasting oxidation:
Impact the small particles sprayed at high speed onto the surface of the processed object to achieve the purpose of removing dirt and processing the surface. High temperature oxidation treatment is carried out after sandblasting to increase the corrosion resistance and aesthetics of the material.
1. Cleaning:
Firstly, immerse the metal parts to be processed in cleaning solution for a period of time to remove oil stains and impurities, and rinse them clean in the sink.
2. Sandblasting:
Put the cleaned metal parts into the sandblasting machine for sandblasting treatment to achieve the required surface roughness.
3. Oxidation:
Place the sandblasted metal parts into an oxidizing solution for oxidation treatment, with the time and temperature depending on the different oxidants used. During the oxidation process, attention should be paid to controlling the liquid level and stirring speed to ensure uniform oxidation effect.
4. Rinse:
After oxidation is complete, remove the metal parts from the oxidation solution and rinse them in a water tank to remove any residual oxidants on the surface.
5. Curing:
Put the cleaned metal parts into the oven for curing treatment, with the time and temperature depending on the different materials and oxidants. After solidification, a hard protective film will form on the surface of the metal parts.
quality restriction:
The quality inspection process should start with raw materials, then proceed to 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 issues with the product.
