What is the reference production capacity?
The reference elevator coating line is designed for about 500 elevator sets per month, depending on workpiece size, operator quantity, curing time, hanging method, and line schedule.
Why is the coating not shiny enough?
Low gloss may be caused by incorrect curing temperature, insufficient curing time, poor powder quality, surface contamination, or uneven oven temperature. Check powder formula, actual part temperature, and curing oven balance.
Why does the coating change color?
Color change can come from over-curing, excessive oven temperature, powder contamination, mixed colors, or unstable heat control. Clean the powder system and verify the curing profile.
Why is the coating surface orange peel?
Orange peel may be related to excessive film thickness, powder formulation, poor leveling, wrong curing profile, or uneven heating. Adjust spray thickness and confirm curing temperature and time.
Why do concave holes or pinholes appear in elevator coating?
Concave holes and pinholes may be caused by oil, water, dust, poor polishing, surface residue, moisture, substrate outgassing, or compressed air contamination. Improve pretreatment and drying.
Why do bubbles appear in the coating?
Bubbles may come from moisture, trapped air, insufficient surface preparation, substrate outgassing, or too-rapid oven heating. Make sure the workpiece is clean and dry before coating.
Why is the coating uneven?
Uneven coating can be caused by poor grounding, unstable powder supply, wrong spray gun distance, uneven operator technique, difficult part geometry, or excessive line speed.
Why are impact strength and adhesion poor?
Poor adhesion or impact strength is usually linked to weak pretreatment, oil residue, under-curing, wrong powder choice, or insufficient actual workpiece temperature during curing.
Why does a small amount of sand appear on the coating surface?
Sand-like particles may come from dust, dirty booth environment, contaminated powder, poor workpiece cleaning, or unclean compressed air. Improve booth cleaning and powder screening.
Why does the coating fall off?
Coating peel-off is usually caused by poor surface preparation, oil residue, weak polishing or cleaning, poor grounding, under-curing, or powder unsuitable for the substrate.
