04
Equipment Quality and Brand
Choose a reputable supplier to ensure equipment reliability, powder room performance, curing stability, and long-term technical support.
05
Energy Saving and Environmental Protection
Evaluate energy consumption, powder recovery, exhaust treatment, dust collection, and compliance with national or local environmental standards.
06
Technical Support and Service
Confirm installation, commissioning, operator training, maintenance support, spare parts, and remote service before purchase.
07
Flexibilité
Select a coating line that can quickly change powder colors and types when your electronic products require different colors or finishes.

Can powder coating be used for PCB coating?
This line is mainly for metal parts used around PCB products, such as PCB-related metal frames, enclosures, chassis, brackets, covers, and component housings. Actual PCB boards normally require specialized electronic protective coating processes, so the substrate and application must be confirmed before quotation.
Which pretreatment method should I choose?
Manual polishing is suitable for navigation radiator surface preparation. Spray pretreatment fits high-volume smart door lock housings. Immersion pretreatment suits speaker parts and components with high grease content or complex shapes.
Why choose PP large cyclone automatic spray room?
A PP large cyclone automatic spray room supports higher output, better powder recovery, and stable coating for repeated products such as smart door lock housings and speaker bodies.
What is the reference production capacity?
Reference outputs include about 180,000 navigation radiators per month, 200,000 electronic door lock housings per month, and 150,000 speaker/audio accessory pieces per month.
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 bubbles, pinholes, or concave holes appear?
These defects may be caused by oil, water, dust, poor pretreatment, surface residue, moisture, substrate outgassing, or compressed air contamination. Improve pretreatment, drying, and compressed air filtration.
Why is the coating uneven?
Uneven coating can be caused by poor grounding, unstable powder supply, wrong spray gun distance, difficult part geometry, poor booth airflow, 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.
Why is powder supply uneven?
Uneven powder supply may be caused by poor powder fluidization, blocked hoses, unstable compressed air, worn pump parts, or damp powder. Check powder supply system and air quality.
Why is powder flying and adsorption poor?
Poor adsorption can be caused by weak grounding, wrong electrostatic voltage, high humidity, poor powder quality, incorrect spray distance, or excessive booth airflow.
What information should I send for a custom electronics coating line quote?
Send product photos or drawings, maximum passing size, workpiece weight, material thickness, monthly output, coating color and finish standard, pretreatment method, factory layout, energy source, and target installation time.
Need an Electronic Products Powder Coating Line Layout?
Send your product drawings, maximum passing size, monthly output target, coating standard, factory layout, energy source, and automation plan. KETU can prepare a suitable electronics coating and electronic component coating configuration.
