Glass Spray Coating Line

Glass spray coating lines are ideal for industrial painting of tempered and annealed glass using solvent-based paints. They feature online cleaning, precise coating control, back-side contamination prevention, and quick drying.

High Performance Glass Spray Coating Line

The glass spray coating line is a fully automated, multifunctional, and high-performance glass deep-processing production line. It is compatible with various coatings, including solid organic, metallic, glass enamel, and water-based paints, and can uniformly spray coatings onto float and tempered glass, drying them within minutes. These glasses can be rectangular, square, round, or even triangular.

Equipped with premier components, including the GRACO painting system sourced from the United States, the glass spray coating line incorporates advanced technologies such as automatic comprehensive glass cleaning, a user-friendly color-changing spraying system, a maintenance-free conveying system, high-temperature drying, automatic marking, and a Manufacturing Execution System (MES). This offers glass manufacturers a dependable, high-quality solution to enhance coating quality, minimize production costs, and ensure manufacturing safety.

The Workflow of Glass Spray Coating Lines is as Follows:

  • Glass Loading from L-rack: The glass automatic loading machine can perform this task very well.
  • Glass Washing and Drying: The horizontal glass washing and drying machine can remove stubborn dust and impurities from glass, leaving it clean and flawless.
  • Primer Spray Coating: The electrostatic spraying system evenly coats the glass surface with a water-based primer and then uses air knives to dry it, improving the adhesion of the subsequent topcoat.
  • IR Preheating Oven: Infrared heating glass to approximately 55-60 degrees Celsius.
  • Reciprocating Spray Coating: Four GRACO spray guns mounted on a single axis reciprocate to evenly coat glass, and the kraft paper conveying system ensures the back of the glass is absolutely clean and free of contamination.
  • Drying and Curing: Infrared gold-plated lamps raise the oven temperature to 150 degrees Celsius, allowing the coating on the glass surfaces to dry completely within 5 minutes.
  • Cooling: High-powered blowers cool glass to below 45 degrees Celsius.
  • Branding: A spray-print printer prints the brand logo on the glass surface.
  • Class Unloading: The automatic glass unloading machine safely places the glass from the spraying line onto the L-rack.

Thin Glass Roller Coating Line

This thin glass roller coating line integrates precision roller coating, drying, and paint circulation functions, enabling uniform application of nano-coatings to the glass surface for use in display glass and cover glass.

Standard Configurations

Glass Washing and Drying Machine

The glass washing and drying machine features a horizontal structure and integrates a high-pressure spray pipe, three sets of nylon soft-and-hard composite brushes, and aluminum alloy air knives to thoroughly clean and dry the glass. The water tank can be pulled out and moved as a whole for easy cleaning and maintenance.

Paper Belt Spray Painting Machine

This advanced glass spraying machine features a spacious spray booth, a high-flow, positive-pressure air system, and a reciprocating spray arm, delivering superior coating results and meeting the requirements of high-end topcoat applications. The Kraft paper conveyor ensures absolute cleanliness on the back of the glass.

High Temperature Drying Oven

This drying oven is densely packed with gold-plated medium- to long-wave infrared lamps, which quickly and evenly heat the interior to 100-250℃, allowing the glass coating to dry within minutes. Its stainless-steel conveying rollers are tightly wrapped with heat-resistant ropes to prevent the glass from slipping or shifting.

Manufacturing Execution System

The spray coating line supports the Manufacturing Execution System, which can monitor line operations in real time and collect production data. After generating reports, the data is automatically uploaded to the company headquarters to achieve centralized digital management and control of the workshop.
