The manufacturing process of sandblasted stainless steel plates

1. Material preparation
The first step in making sandblasted stainless steel plates is to select the appropriate stainless steel base material. Commonly used stainless steel materials include grades such as 304 and 316. Select the corresponding material based on the actual application requirements. After selection, the stainless steel plate needs to be preliminarily cleaned to remove dust, oil stains and oxide layers on the surface to ensure the effect of the subsequent sandblasting process.
2. Surface treatment
Before sandblasting, stainless steel plates need to be pre-treated. It usually includes the following steps:
- Degreasing cleaning: Use chemical cleaning agents or alkaline cleaning solutions to remove grease and dirt from the surface of stainless steel.
- Pickling and passivation: By using pickling solution to remove the oxide scale on the surface, the corrosion resistance of stainless steel is simultaneously enhanced.
- Drying treatment: Thoroughly dry the cleaned stainless steel plates to prevent moisture residue from affecting the quality of sandblasting.
3. Sandblasting process
Sandblasting is the core step in the entire production process. Its main purpose is to grind the surface of stainless steel by spraying abrasive particles at high speed, thereby achieving a uniform matte or glossy effect. The sandblasting process usually includes the following points:
- Select abrasives: Commonly used abrasives include quartz sand, glass beads, alumina, etc. Different abrasives will affect the final surface effect.
- Adjust equipment parameters: According to the required surface roughness and texture effect, adjust the air pressure, spraying speed and nozzle distance of the sandblasting machine.
- Uniform spraying: During the operation, it is necessary to ensure that the abrasive evenly covers the surface of the stainless steel plate to avoid color differences or uneven textures.
4. Follow-up processing
After sandblasting is completed, there may be residual abrasive particles or dust on the surface of the stainless steel plate, so cleaning treatment is required. The specific steps are as follows:
- Clean up residues: Use high-pressure gas or clean water to rinse off the residues on the surface.
- Anti-fingerprint treatment (optional) : To enhance the product's stain resistance and ease of cleaning, an anti-fingerprint coating treatment can be applied after sandblasting.
- Surface protection: To prevent scratches during transportation or storage, a protective film can be applied to the surface of the stainless steel plate.
5. Quality Inspection
After all the process flows are completed, quality inspection of the sandblasted stainless steel plates is required to ensure that their appearance effect and performance meet the requirements. The detection contents include:
- Surface uniformity: Check for color differences, streaks or spots.
- Roughness measurement: Use professional instruments to measure the roughness parameters of the surface.
- Corrosion resistance testing: The corrosion resistance of materials is detected through methods such as salt spray tests.
