High-Efficiency Automatic Spray Coating Line for Wine Trays & Cosmetic Packaging (External Surface)

High-Efficiency Automatic Spray Coating Line for Wine Trays & Cosmetic Packaging (External Surface)

1. Composition of Production Line

This fully automatic spray coating line consists of the following integrated modules:

1. Automatic Infeed Conveyor – Belt or roller conveyor with product alignment guides

2. Pre-Treatment Station (Optional) – Plasma, flame, or corona treatment for better adhesion

3. Spray Coating Booth – Enclosed stainless steel booth with exhaust and filtration system

4. Multi-Nozzle Spraying System – Programmable reciprocating spray guns or robotic arms

5. Conveyorized Drying/Curing Tunnel – IR lamps or hot air convection heating

6. Cooling Zone – Forced ambient air cooling before handling

7. Unloading/Stacking Conveyor

8. Central Control Cabinet with HMI – PLC control, recipe storage, and real-time monitoring

2. Product Description

Our High-Efficiency Automatic Spray Coating Line is specially designed for applying protective and decorative coatings to the external surfaces of industrial packaging items, including wooden/plastic wine trays, glass or plastic cosmetic bottles, compacts, jars, and caps. The line combines precision spraying with fast drying, delivering a smooth, even, and high-gloss finish that enhances product appearance and durability. With programmable spray parameters and customizable conveyor configurations, it ensures consistent quality and high throughput for medium-to-large scale production.

3. Technical Parameters

4. Application

• Wine trays (wooden, plastic, or foam) – decorative and protective coating

• Cosmetic packaging – bottles (glass/plastic), caps, jars, compacts, and palettes

• Other industrial packaging – luxury boxes, electronic accessories, perfume caps

• Coating types: Primer, base coat, topcoat, anti-scratch, anti-fingerprint, matte/gloss finishes

5. Customization

This spray coating line is designed to be highly customizable for your specific product shapes and production volume:

• Conveyor width and type – belt, chain-on-edge, or rotating fixture plates

• Spray gun arrangement – top, side, tilt, or orbital patterns for complex 3D surfaces

• Masking / fixture design – custom product holders to avoid coating on non-target areas

• Drying tunnel length and temperature zoning – to match your coating chemistry

• Control integration – Can be customized to communicate with upstream/downstream equipment via industrial protocols (Profibus, Ethernet/IP)

6. Key Features

• High coating uniformity – Programmable spray overlap and speed control eliminate streaks and unevenness

• Fast changeover – Quick-release gun mounts and recipe-based settings reduce downtime

• High transfer efficiency – HVLP nozzles reduce overspray and material waste

• Robust construction – Stainless steel interior, easy to clean and maintain

• User-friendly HMI – Real-time monitoring of speed, temperature, and spray parameters with fault diagnostics

7. Support and Services

• Pre-sale consultation – Free layout and capacity simulation

• Installation & commissioning – On-site or remote guidance by senior engineers

• Operator training – Comprehensive training on spray parameter setting, cleaning, and safety

• After-sales – 12-month warranty, lifetime remote support, spare parts stock

8. Packing and Shipping

• Packing – Each major module (booth, tunnel, conveyor, control cabinet) is securely packed in export-grade wooden crates with moisture-proof film and shock-absorbing foam.

• Shipping – Shipped via sea freight (FOB, CIF, EXW terms). Air freight available for urgent orders. All customs documents included. Lead time: 8–12 weeks for customized configurations

9. FAQ

Q1: Can this line coat irregularly shaped items like wine trays with deep cavities?
A: Yes. By using customizable spray gun angles (e.g., tilt, rotary, or robot arm) and product fixtures, we can achieve full external coverage even for complex 3D shapes.

Q2: How do you prevent overspray on non-target areas (e.g., inside of a container)?
A: We offer customizable masking fixtures and shielding jigs to protect internal surfaces. The spray system can also be programmed to apply coating only where needed.

Q3: What is the typical curing time for water-based coatings on glass bottles?
A: Drying time depends on coating thickness and temperature. With our 6m IR + hot air tunnel at 80–120°C, typical curing takes 3–5 minutes. We can customize tunnel length accordingly.

Q4: Can the line be upgraded from manual to automatic loading later?
A: Absolutely. The conveyor interface is designed for future integration with robotic loaders or automatic tray feeders as a customization option.

Q5: Do you provide sample coating trials?
A: Yes. We offer a sample testing service at our facility. Send us your products and coating material; we will run trials and provide a process parameter report and coated samples for your approval.
