How to Choose roller coating line of composite sheet?

With competitive price and timely delivery, Litong sincerely hope to be your supplier and partner.

This fully automatic coating line is a great flat glass coating solution incorporating a combination of roller coating and IR drying technologies. Thanks to the expertise and know-how gained in the glass coating field, verified during years of activity, the glass roller coating and drying line is highly configured to enable the coating process to be carried out reliably and precisely.

Reasonably integrating glass sheet loading, roller coating, transfer conveying, IR drying, cooling and unloading, this automatic glass roller coating line not only meets rigid standards of the industry, but also offers high level of automation and flexibility.

Integrated Glass Coating Solution Designed for Your Needs

We know that different glass manufacturers have different needs for glass coating. With that in mind, the design of this glass roller coating line allows users to select the equipment width with modified configurations to suit their demands and budget. In addition, our glass coating line can be provided in either straight line layout or configured with transfer conveyors to accommodate the routing in the glass processing plant.

Beneficial Features of Glass Roller Coating Line

• Premium Quality
  The coated glass sheet features a smooth surface and an even coating layer, without color difference. The colored painted can be coated on glass to achieve no light transmission.
• High Efficiency
  A single glass coating line can achieve a daily output capacity in range of 800 to meters (8 hours/day)
• Reduced Labor Intensity
  Roller coating process assures faultlessness of four edges without coating defects and oil stains, so that the need for manual grinding and polishing is eliminated therefore enabling the coated glass sheets to be directly packaged.
• Low Cost
  Paints and coatings are recycled, reducing waste and removing the need to frequently replace damaged screens, which would save both cost and time.
• Environmental Sustainability
  Roller coating is considered as an ideal alternative to spray coating and screen printing or other conventional coating methods in terms of environmental concerns. Roller coating helps reduce the environmental impact since it can prevent paints from spattering, it is in full compliance with the requirements of environmental regulations.

• 2. Double Roller Coater for Glass

     Model: SR-R2PL Series

     This double roller coater is specifically designed for applying coatings on flat glass sheets. It utilizes two application rollers to transfer coatings on flat workpiece surface evenly, with less paint consumption and higher productivity.
     HMI interface control system enables parameters to be input manually according to the working conditions.

• 2. IR Dryer

     Model: IR Series

     This IR dryer is a glass drying tunnel primarily used in glass coating line for drying and curing flat glass after coating. There are two standard sections in the infrared drying tunnel, i.e. IR heating zone and observation zone. Variable speed drive is adopted in conveyor for stepless speed adjustment, and drying temperature can be freely set within a range of room temperature to 250'.

     Specifications of IR- Glass Drying Tunnel (as an example)
     Drying Tunnel Width: mm
     Feeding Width: mm
     Drying Tunnel Length: mm
     Feeding Speed: 1-12m/min
     Temperature Adjustment Range: Room temperature to 250'
     Medium-Wave Infrared Tube: 0.8×54=43.2kW
     Motor Power: 4.5kW
     Total Power: Approx. 47.7kW
     Dimensions: Approx. ××mm

Our roller coating technology allows for a wide array of finishes. You can choose from transparent to various colored coatings, and select the desired level of sheen, from transparent to colored, matte, semi-gloss, or glossy. What's more, these lines can apply specialized coatings like aluminum oxide or corundum-based ones, which are excellent for creating surfaces that stand up well to wear and tear, a crucial factor in high-traffic areas or in products that face regular use.
