Deqing Leixin Coating Equipment Co., Ltd., a manufacturer with over a decade of expertise since 2011, proudly presents the Manual Assisted Automatic Powder Coating Line — a versatile solution meticulously engineered for irregular metal parts. Combining automated efficiency with the flexibility of manual intervention, this production line addresses the unique challenges posed by complex geometries, mixed batches, and delicate surfaces. Backed by our ISO9001-certified quality management system and a factory spanning 1,000–3,000 square meters with 51–100 skilled employees, we deliver robust equipment that enhances throughput while maintaining precise coating control. Whether you are serving automotive, furniture, or heavy equipment sectors, this line provides the adaptability needed to achieve consistent, high-quality finishes on parts that defy traditional automation.
At the heart of this system lies a PLC-controlled automatic spraying unit paired with a carefully designed manual assistance workstation. The automatic section handles high-volume, repetitive coating of simpler surfaces, while the manual station enables operators to focus on recessed areas, edges, and irregular contours that require extra attention. This hybrid approach significantly reduces powder waste — typically achieving coating efficiency of ≥95% — and minimizes rework. The conveyor speed is adjustable from 0.5 to 5 meters per minute, allowing you to fine‑tune the line for different part sizes and coating thickness requirements.

Product Highlights & Customer Benefits
Adaptive coating solution: The manual assistance feature allows precise coating of irregular shapes such as castings, forgings, welded assemblies, and parts with deep cavities. This dramatically reduces the need for rework compared to fully automatic lines.
High powder utilization: With an integrated recovery system that recaptures up to 98% of overspray powder, you minimize material waste and lower operating costs. The efficient cyclone and cartridge filter ensure consistent powder quality for reuse.
User‑friendly operation: The PLC touch screen interface stores dozens of coating recipes. Switching between different part types takes just minutes. Manual stations are ergonomically designed to reduce operator fatigue.
Consistent quality output: Automatic guns provide uniform film thickness on accessible surfaces, while manual stations handle detail work. The result is a flawless finish free of orange peel, pinholes, or thin spots.
Flexible scalability: The modular design allows you to add pre‑treatment zones, additional spray booths, or extended curing ovens as your production grows. Conveyor layout can be configured as straight or L‑shaped to fit your floor space.
Global compatibility: All electrical components comply with CE and IEC standards. Voltage options (380V/220V) and frequency (50/60 Hz) are adjustable per request. We also provide multilingual manuals and remote support.

Frequently Asked Questions
Q: What is the maximum part weight the conveyor can handle?
A: The standard conveyor is rated for parts up to 50 kg per hanger. For heavier parts, we can reinforce the chain and trolley system — please contact us for custom design.Q: Does the line include pre‑treatment? Can it be added?
A: The basic configuration does not include pre‑treatment, but we offer optional spray washing or immersion tanks as modules. The modular design allows easy integration before the coating booth.Q: How long does it take to switch between different part shapes?
A: With recipe storage on the HMI, switching takes approximately 5–10 minutes. Manual adjustments (e.g., changing gun positions) may add 2–3 minutes.Q: What powder types are compatible?
A: The system works with thermoset powders (polyester, epoxy, hybrid, polyurethane) and some thermoplastic powders. For specialized powders, we can adjust gun parameters and recovery settings.Q: Do you offer installation and training?
A: Yes, we provide on‑site installation guidance and operator training for 3–5 days (travel expenses separate). Remote video support is also available during commissioning.Q: What is the typical delivery time?
A: For standard configurations, delivery is 30–45 days after deposit. Customized lines may require 60–90 days depending on complexity.Q: Is spare parts support available?
A: Yes, we maintain a stock of common spare parts (guns, nozzles, filters, motors). We can supply within 7–15 working days for urgent needs.Q: How is the powder recovery system maintained?
A: The cartridge filters can be cleaned by reverse pulse jet; replacement filters are available every 1–2 years depending on usage. The cyclone separator requires minimal maintenance — just periodic inspection for wear.
