Now our many parts for die casting/investment casting&cnc has chosen the powder coated as their surface treatment.
As a metal surface treatment technology, there are some advantages as following:
1. The production process has no pollution to the environment and no harm to the human body
2. Lower cost than painting
3. Strong adhesion, high corrosion resistance and drop resistance
Progress for powder coated
In order for the plastic powder to be adsorbed on the metal surface, the surface must be treated first: degreasing- washing-acid washing-water washing-meter adjustment-phosphating-washing and drying.
Test procedure for powder coated
After the temperature drops, the parts shall be inspected according to the regulations when packing. According to the product characteristics, the inspection requirements are as follows:
1. Conventional products or newly modified powder coated products must meet the requirements of the order swatch without obvious color difference
2. The powder coated color should meet the requirements of the order swatch and be basically consistent with it. The surface of the powder coated product has uniform color and no obvious color difference by visual inspection
3. The surface is not allowed to fall off, expose the bottom, sag, pinholes, orange peel, bumps, scrapes, deformation and rust, etc., and should be flat, without corners and corners, and should be maintained. Clean, no stains, oil stains, etc. that affect the appearance, and no leftover white marks are allowed
