Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. As a trusted provider, Leo Surface Coatings engineers industrial powder coating line solutions specifically for this process. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer, processed through our automatic powder coating line and CED coating line manufacturer systems for clients across India and worldwide.
-
Pre-treatment: The metal surface is cleaned and prepared using our spray and dip pre-treatment systems to ensure optimal adhesion of the powder coating.
Application: Powder is applied to the metal part using an electrostatic spray gun as part of our automatic powder coating line. The powder particles are charged and attracted to the grounded metal part.
Curing: The coated part is placed in an industrial oven, where the powder melts and fuses to form a smooth, durable coating — supported by our automated paint drying chambers and dry-off and baking ovens.
-
Durability: Powder coatings offer excellent resistance to scratches, chips, fading, and corrosion ideal for heavy engineering and industrial applications.
Environmental friendliness: Powder coating is a solvent-free process, resulting in less waste and air pollution, supported by our paint shop effluent treatment plants (ETP)
Thickness: Powder coatings can create thicker coatings without runs or sags.
Finish quality: Consistent and uniform finish with a wide range of colours and textures, delivered through our industrial powder coating line manufacturer expertise.
Cost-effective: Less material waste compared to liquid paint, reducing operational costs for automotive and manufacturing sectors.

Frequently Asked Questions
Everything you need to know about our best industrial powder coating line solutions, automatic powder coating plant configurations, and custom engineering.
A dry, electrostatically charged powder is applied to the metal part, then cured under heat until it melts and fuses into a hard, uniform coating. Because there's no solvent to evaporate, the process produces far less waste than liquid painting.
Generally, yes powder coatings resist chipping, scratching, and fading better than most liquid paints, and they can be applied thicker without running or sagging, which is why they're common on parts exposed to heavy handling or outdoor weathering.
In most cases. The two processes need separate booths and curing setups, but Leo Surface Coatings has integrated powder lines into existing facilities without requiring a full shutdown or rebuild the pre-treatment stage can often be shared between both.
Automotive parts, industrial machinery, appliances, and structural steel components see the heaviest use, mainly because these products need to survive years of wear, weather, or repeated handling without the finish degrading.
Line length, oven size, automation level (manual spray guns vs. robotic application), and throughput requirements all factor in. A smaller manual line for low-volume parts costs a fraction of a fully automated high-throughput system.
