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

Customization Options
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)
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
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
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
Frequently Asked Questions
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.
