Custom Spray Gun Configuration Spray Coating Machine with Uniform 3D Coverage and Adjustable Conveyor Speed

This automatic spray coating machine is designed for applying waterproof, oil-proof, and functional coatings onto molded pulp products such as food trays, bowls, cups, clamshells, and industrial packaging. The multi-gun spray system, combined with a rotating fixture conveyor, delivers uniform coverage across complex 3D shapes — including sidewalls, corners, and deep cavities that roller coating cannot reach reliably.

The spray booth features adjustable gun angle, distance, and flow rate, allowing precise control of coating thickness and consumption. The integrated drying tunnel sets the coating quickly, while the exhaust system captures overspray and VOCs for a cleaner working environment. The PLC/touchscreen control system stores recipes for different product shapes, reducing changeover time.

Key customizable elements include spray gun quantity and configuration, conveyor type and speed, drying tunnel length and heating method, and full integration with existing pulp molding lines.

All specifications are reference values. Final parameters are fully customizable based on your pulp product shape, coating chemistry, and production speed.

• Food Packaging — Waterproof and oil-proof coating for molded pulp food trays, bowls, plates, cups, and clamshells.
• Tableware & Foodservice — Coating for disposable and reusable pulp tableware requiring grease and moisture resistance.
• Industrial Packaging — Protective coatings for pulp-based electronics packaging, cushioning inserts, and shipping trays.
• Agricultural & Nursery — Functional coatings for pulp seedling trays and agricultural containers.
• Consumer Goods — Decorative or protective coating for pulp-based cosmetic packaging and display items.

Share your pulp product shape, coating requirement, and target throughput, and we will recommend the optimal custom spray configuration.

Every molded pulp product has a different shape and coating requirement. Our spray coating machines are highly customizable:

• Spray Gun Configuration — Quantity, type (air spray / airless / HVLP), nozzle size, and spray angle matched to your product geometry.
• Conveyor & Fixture Design — Chain, belt, or fixture conveyor with custom fixtures for trays, bowls, cups, or irregular shapes; rotation for 360° coverage.
• Drying Tunnel — Length, heating method (hot air / IR / UV), and temperature profile customized to your coating chemistry.
• Exhaust & Filtration — Sized and configured to meet local VOC and environmental regulations.
• Control System — PLC or touchscreen HMI with recipe storage; remote monitoring optional.
• Line Integration — Infeed and outfeed matched to your existing pulp molding machines or packaging lines.

Customization is available from single-unit orders. Share your product samples and requirements for a tailored solution.

• Uniform 3D Coverage — Multi-gun spray system with rotating fixtures reaches sidewalls, corners, and deep cavities that roller coating cannot.
• Adjustable Spray Parameters — Gun angle, distance, and flow rate adjustable for precise coating thickness and minimal overspray.
• Low Coating Consumption — Optimized spray pattern and overspray recovery reduce coating waste.
• Recipe Storage — PLC/touchscreen stores recipes for different product shapes, reducing changeover time.
• Quick Drying — Integrated hot air, IR, or UV tunnel sets the coating fast for high line speeds.
• Clean Working Environment — Enclosed spray booth with exhaust and VOC filtration captures overspray and fumes.
• Stable Conveyor Tracking — Anti-offset guide system prevents product drift during spraying.
• Safety Design — Interlocked booth doors, flame detection, and external status indicators for safe operation.
• Easy Maintenance — Access panels for gun cleaning and booth maintenance; consumables available for fast replacement.

• Pre-Sales Consultation — Engineers review your pulp product shape, coating chemistry, and layout to recommend the optimal custom spray configuration.
• Sample Testing — Send your pulp samples and coating material; we test them on our equipment and confirm coverage and adhesion before you order.
• Layout Design — 2D/3D line layout and utility requirements provided with the proposal.
• Installation Support — Remote guidance or on-site assistance depending on destination.
• Training — Operation, gun adjustment, and maintenance training via video, documentation, or on-site sessions.
• Warranty — 1-year warranty on non-consumable parts; extended options available.
• After-Sales Support — Lifetime technical support; spare guns, nozzles, and consumables with fast turnaround.
• Documentation — Operation manual, electrical schematics, and maintenance schedule provided.

• Packing — Export wooden case with moisture barrier and shock-absorbing padding; spray guns and fragile components packed separately. Custom crating for oversized lines.
• Shipping Methods — Sea freight (FCL/LCL), air freight, or land transport.
• Lead Time — Standard models ship within 15–25 working days. Customized configurations typically require 35–50 working days after specification and sample confirmation.
• Shipping Terms — FOB, CIF, or EXW available. We coordinate with your freight forwarder or arrange door-to-door delivery.
• Documentation — Commercial invoice, packing list, bill of lading, and certificate of origin provided.
