Automatic powder coating line for yacht manufacturing
Project Background
With the development of the high-end yacht market, customers have put forward strict requirements for the decoration, weather resistance, and environmental standards of yacht appearance A well-known yacht manufacturing enterprise has decided to upgrade its surface treatment workshop and introduce an automated powder coating production line for small and medium-sized yacht hull and deck structural components in order to replace the traditional high pollution liquid paint process and solve the problem of low efficiency of manual spraying.
Process Flow
Pre processing stage:
Automatic powder coating spraying stage:
Powder recovery system:
High temperature curing stage:
The workpiece enters the immersion treatment tank through a suspended conveyor chain, and undergoes oil removal, rust removal, and phosphating treatment in sequence. Then it enters a hot air circulating oven for thorough drying to ensure that the substrate surface is free of water and oil, providing the best foundation for powder adhesion.
This is the core of the production line. Equipped with automatic elevators and reciprocating automatic spray gun units. The system controls the spray gun to perform multi angle and multi-level reciprocating scanning spraying based on preset yacht component contour parameters. Significantly reduced the frequency of manual powder supplementation.
Unadsorbed overspray powder is collected through the cyclone recovery device at the bottom and the secondary recovery system of the filter element. After screening, it is sent back to the powder supply center for recycling, achieving high utilization rate of the powder
The sprayed yacht components enter the gas heating curing oven. Bake at a constant temperature of 180 ℃ to 200 ℃ for about 20 minutes to melt and level the powder coating, forming a high hardness and high gloss protective coating.
Project Results
Significant environmental benefits: It completely solves the problems of exhaust gas and wastewater pollution caused by traditional spray painting, fully complying with national and local environmental regulations.
Excellent coating performance: Compared with traditional paints, powder coatings perform excellently in terms of UV resistance, seawater corrosion resistance, and impact resistance, greatly extending the service life of yachts in marine environments
Production efficiency improvement: Automated continuous operations have replaced tedious manual operations, shortened production cycles, and made color changing and cleaning convenient and fast, adapting to the production mode of yacht manufacturing with multiple varieties and small batches.
Cost savings: High powder utilization rate and no need for primer, significantly reducing material costs.
Summary
The successful production of the automatic powder coating line for the yacht not only enhances the overall quality and market competitiveness of yacht products, but also provides a replicable benchmark case for the green transformation of the yacht manufacturing industry.
