High-Temperature Spray Coating Solution for Glass Bottles

Integrated Circular Ground-Rail Spraying & High-Temperature Tunnel Oven Curing — engineered for superior adhesion, abrasion resistance, and mirror-like gloss on glass substrates.

I

Overview

Engineered for small-to-medium batch production of glass substrate coating with exceptional quality and consistency.

Developed by Geetech (Dongguan Juting Electromechanical Equipment Co., Ltd.), this solution addresses persistent coating challenges on glass substrates—specifically poor adhesion, low abrasion resistance, and inconsistent gloss. By integrating Circular Ground-Rail Spraying with a High-Temperature Tunnel Curing Oven, the system is optimized for small-to-medium batch production (1,000–5,000 pcs/day). Its versatility makes it a strategic asset for manufacturers in the cosmetics, food & beverage, pharmaceutical, and household goods sectors seeking to enhance product aesthetics and market competitiveness.

Process Flow

Streamlined eight-stage process from loading to unloading ensures optimal coating quality.

Loading → Static Dust Removal → Preheating → Auto Spraying (Circular Line) → Leveling → High-Temp Curing (Tunnel Oven) → Cooling → Unloading

Key Highlight: Precision Thermal Curing

Post-spraying, workpieces enter the High-Temperature Tunnel Oven. Within precisely controlled zones (standard 180°C–250°C; up to 600°C for specialty glazes), the coating undergoes complete cross-linking. Unlike air-drying, thermal curing significantly boosts film hardness, chemical resistance, and aging stability. It effectively eliminates "orange peel" textures, guaranteeing a consistent, mirror-like high-gloss finish.

Core Configuration

Three integrated subsystems working in harmony for precision glass bottle coating.

Circular Ground-Rail Spraying System

Space-saving compact design. Equipped with high-precision reciprocating spray guns for multi-angle profiling, effectively handling round, irregular, and handled bottles while maximizing transfer efficiency and minimizing paint waste.

High-Temperature Tunnel Oven

Positioned downstream with zoned temperature control and high-density rock wool insulation. A proprietary hot air circulation system ensures uniform heat distribution, mitigating thermal stress to prevent bottle deformation or breakage.

Smart PLC Control System

Centralized PLC control with HMI touchscreen. Supports multiple recipe storage for various bottle types, allowing operators to switch spraying parameters and curing curves with one click, facilitating rapid changeovers and reducing manual dependency.
