02 Electrostatic Spraying Equipment
Electrostatic generator and spray guns charge powder particles and apply them evenly to grounded machinery workpieces.
03 Spray Room System
Backpack, walk-in, PP large cyclone, or hybrid powder rooms can be selected according to workpiece size and output target.
04 Conveying System
Conveyor, hooks, hanging fixtures, and loading pitch are designed for large shells, heavy frames, and mixed mechanical parts.
05 Curing Furnace
Natural gas curing, hot air circulation, and variable temperature control help powder form a durable, smooth, and protective coating film.
06 Control and Environmental System
PLC control, powder recovery, dust collection, exhaust, alarm system, and operator safety devices support stable and eco-friendly production.Process Flow
Complete Machinery Powder Coating Process
The process can be adjusted according to product type. CNC shells use grinding and manual polishing pretreatment, while furniture machinery parts can use spray pre-treatment and drying furnace.Stage 1: Workpiece Pretreatment
CNC shells may be manually polished or ground. Furniture machinery parts may use spray pre-treatment to clean oil, dust, and surface contamination.Stage 2: Hanging Workpiece
Machinery shells and parts are hung on fixtures. Correct hanging improves grounding, spray access, operator safety, and line balance.Stage 3: Drying Furnace
For spray pre-treatment lines, the drying furnace removes moisture before powder coating to avoid bubbles, pinholes, and adhesion defects.Stage 4: Powder Coating
Powder is charged through electrostatic spraying equipment and evenly adsorbed onto grounded mechanical workpieces.Stage 5: Curing Furnace
The coated workpiece exits the powder coating room and enters the natural gas curing furnace. Powder melts, levels, and forms a durable film.Stage 6: Cooling and Removing Workpiece
After curing is completed, the workpiece is cooled, removed, inspected, and prepared for assembly, packaging, or shipment.Features

What machinery products can this powder coating line handle?
It can be configured for CNC machine shells, furniture machinery, woodworking machinery, industrial equipment housings, machine frames, protective covers, cabinets, structural components, and mechanical parts.
Why is powder coating suitable for machinery?
Electrostatic powder coating forms a smooth, uniform, highly adhesive coating. It is eco-friendly, efficient, energy-saving, and can improve weather resistance, wear resistance, insulation, appearance, and service life.
What is the reference CNC machinery coating capacity?

Which spray room should I choose?
Backpack and walk-in powder rooms are suitable for large CNC machine shells and custom equipment housings. PP large cyclone powder room is suitable for repeated furniture machinery parts and higher-output production.
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, insufficient drying, moisture, substrate outgassing, or compressed air contamination. Improve pretreatment, drying, and booth cleanliness.
Why is the coating uneven on large machine shells?
Uneven coating can be caused by poor grounding, wrong spray angle, unstable powder supply, difficult shell geometry, operator inconsistency, or workpiece swing. Hanging and grounding should be checked first.
Why does the coating fall off?
Coating peel-off is usually caused by poor surface preparation, oil residue, weak pretreatment, under-curing, poor grounding, or powder unsuitable for the substrate and use environment.
How should I choose oven size for machinery coating?
Oven size should be based on maximum passing size, workpiece weight, metal thickness, curing time, loading spacing, and production output. Large machine shells need enough heat absorption time and stable hot air circulation.
What information should I send for a custom machinery 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.
