Powder Coating Application Equipment @Xintu
What are powder coatings?
Powder coatings are 100% solvent-free coatings in solid, dry powder form. Unlike liquid paints, they contain no water or solvents and release zero volatile organic compounds (VOCs) or hazardous air pollutants (HAPs).
Key characteristics of powder coatings:
Solvent-free, water-free, sustainable and eco-friendly
Lowest carbon footprint in the paint industry
High material utilization rate of >90% (overspray can be recycled)
High durability, corrosion resistance, and mechanical strength
Applied electrostatically and cured by heat (melting & chemical crosslinking)
One-layer coating capable of achieving high film thicknesses
Available in a wide range of resin chemistries (epoxy, polyester, hybrid, polyurethane, etc.)
More cost-efficient than liquid coatings over the long term
Mainly applied on heat-stable metal substrates, but also on wood, MDF, and plastics with low-temperature curing systems
✅ Why this matters for your production line:
The efficiency of powder coating application—especially overspray recovery and consistent film thickness—depends directly on your spray booth, powder recovery system, and curing oven. Xintu designs and manufactures all these core components.
What are powder coatings made of?
Powder coatings consist of finely ground, solid, dry components:
| Component | Function |
| Resin (binder) | Forms the continuous film; determines mechanical and chemical properties (epoxy, polyester, etc.) |
| Pigments | Provide color and hiding power |
| Fillers (extenders) | Improve mechanical properties, reduce cost, control gloss |
| Additives | Control flow, leveling, degassing, texture, UV resistance, etc. |
| Curing agents (crosslinkers) | React with resin during oven curing to form a durable thermoset film |
🔧 Xintu’s role:
Xintu does not manufacture the powder itself. We provide the application equipment that applies these coatings onto your products. You purchase powder from coating suppliers (e.g., AkzoNobel, PPG, Sherwin-Williams); Xintu ensures it is applied efficiently, uniformly, and with minimal waste.
How are powder coatings applied?
Xintu focuses entirely on the application side—taking the finished powder and applying it to your metal parts with high efficiency and consistency.
| Step | Who does it | Xintu’s involvement |
| Powder storage & handling | End user | Xintu fluidized hoppers, powder feed centers |
| Electrostatic application | End user | Xintu spray guns, automatic reciprocators |
| Overspray recovery & recycling | End user | Xintu cyclone + cartridge filter systems |
| Curing | End user | Xintu curing ovens (gas, diesel, electric) |
| Conveying & line integration | End user | Xintu conveyor systems, PLC controls |
🏭 For industrial finishers:
You need a reliable system to apply it. That is exactly what Xintu provides.
Which materials can be powder-coated?
Substrates that can be powder-coated
| Substrate Type | Typical Applications | Requires Low‑Temperature Cure? |
| Metals (most common) | Steel, aluminum, galvanized, stainless steel – auto parts, furniture, fences, appliances, facade panels | No (standard 180–220°C) |
| Glass & ceramics | Decorative panels, bottles, sanitary ware | Yes (special low-temp powder) |
| Wood, MDF, plastics | Furniture, electronics housings, automotive interiors | Yes (cure below 130°C) |
🌡️ Xintu’s advantage:
We manufacture standard curing ovens (for metal) and low-temperature curing ovens (for heat-sensitive substrates). Our ovens feature uniform air-circulation tunnels to minimize energy consumption while ensuring precise cure.
Typical application examples (industries we serve)
Metal furniture & shelving – Office cabinets, racks, lockers
Appliances – Refrigerator panels, washing machine drums, microwave cavities
Facade & architectural elements – Aluminum window frames, curtain walls, railings
Agricultural & construction machinery – Tractor parts, scaffoldings, guardrails
Automotive parts – Wheels, chassis components, under‑hood brackets
Bicycle frames – Both metal and carbon frames with low‑temp powder
General metal fabrication – Enclosures, control boxes, stamped parts
How do Xintu coating systems contribute to powder coating success?
Xintu provides the application and curing equipment that makes the entire process work reliably in a production environment.
Xintu’s systems directly address the four biggest challenges in powder coating:
| Challenge | Xintu Solution | Benefit to Customer |
| Inconsistent film thickness | PLC‑controlled reciprocators & multi-axis robots with frequency‑controlled movement | Uniform coating, less rework |
| Low powder transfer efficiency | High-performance electrostatic spray guns + efficient booth airflow design | Powder savings >30%, lower material cost |
| Overspray waste | Multi-cyclone + cartridge filter recovery system (up to 98% recovery) | Nearly all overspray is reusable, minimal disposal cost |
| High energy consumption | Energy‑efficient curing ovens with uniform air circulation and insulation | Lower utility bills, faster ROI |
