How to produce high-quality aluminum plate?
What quality inspection process does aluminum plate go through before leaving the factory?
According to current aluminum plate industry standards, manufacturers should conduct a necessary quality inspection. The inspected items include gloss deviation, film thickness, acid resistance, sealing quality, etc.
1. The factory inspection rules for the aluminum plate.
The factory inspection of products usually consists of the same variety, color, production batch, and actual delivery quantity.
2. The quality sampling methods of aluminum plate.
The appearance of the aluminum plate and the connection of welding nails should be inspected piece by piece.
It would help if you carried out the size, gloss deviation, and film thickness according to regulations.
Take two pieces of aluminum plate from each batch to test adhesion, sealing quality, and acid, mortar, solvent, and impact resistance.
3. The quality judgment and re-inspection rules of aluminum plate.
If one or more properties are unqualified in the inspection results, take a double sampling from the batch for re-inspection.
If one or more properties are still unqualified in the re-inspection results, it is determined that the batch of products is unqualified.
When the appearance quality of an aluminum plate is unqualified, it is a single piece unqualified.
When the film thickness, size, and gloss deviation results exceed the upper limit of unqualified products, it is determined that the batch is unqualified. However, suppliers can inspect individually and deliver qualified products.
