Adopting electrochemical grinding and magnetic grinding processes, the punching gap is precisely controlled during the mold design stage, and negative gap punching is used to reduce burrs from the source; After stamping, deburring treatment is carried out to ensure that there are no sharp edges. Then, a 100% full inspection of the workpiece surface is carried out to screen out scratches, burrs, and products with substandard smoothness, ensuring that the delivered parts meet medical or optical surface standards.

Prev：Establish standard color palette, lock materials, pre-treatment and oxidation coloring process parameters. Select high-purity aluminum materials from the same batch, strictly control degreasing and chemical polishing parameters; The oxidation tank is automatically refilled with liquid, with precise temperature control and stable flow. The oxidation time is controlled in seconds to ensure consistent coloring conditions for each batch.
