Application of new powder coating production line

recently, AmericanDesk in the United States introduced a new coating line, increasing productivity by 50%any paint coating manufacturer must consider such important issues as coating costs, the quality of coating products, and the productivity of the coating process when replacing oily coatings with powder coatingsThe most fundamental problem for AmericanDesk is finding a good coating systemAmericanDesk is a major manufacturer of office furniture and utilitiesIts products include in-house facilities such as classrooms, concert halls, gymnasiums, dormitories and laboratoriesAmerican Desk's original two high-solid oil-based coating lines have been in operation for 30 yearsThe driving force that prompted the company to replace the oil-based coating line with the powder coating line was the increased cost of waste disposal and the limitation of solvent emissions from the coating processAt the same time, the cost of operating oil-based coating lines is growing faster than the increase in the profit of coating productsThe new powder coating line enables AmericanDesk to produce high-quality products at a lower cost in a cleaner environmentNot to mention its ability to adapt to new environmental regulations in the futurecoating system was designed
in January 1993, AmericanDesk removed an oil-based coating line and built a new powder coating lineThe powder coating line took about 6 months to build, during which time all products were coated on the retained oily coating lineAfter the powder coating line began to operate, the company removed another oil-based coating line in September 1993powder coating system includes:, five-segment sink, 6min drying furnace , two powder paint booths, each with 14 powder spray guns , two oil-based paint booths
25min ovens , three drive units of the 1,700-foot long closed-circuit conveyor belt it is very difficult to place all of these equipment in a place of only 9,500 square feet In addition to having two powder jets, the coating line also retains two oil-based paint booths, which AmericanDesk hopes will be designed to meet the customer's small batch special color coating processing needs Nordson is the contractor for the coating line and is responsible for the design, construction and installation of equipment including conveyor belts, ovens, powder coating booths, etc Milbank Systems provided the coating line's washing tanks and ovens This five-segment sink has a stainless steel top cover The first paragraph has an alkali washes, the third with an acid washing device and a phosphating device There is a chemical concentration detection control on the sink Pre-treatment devices are also specially designed for aluminum or steel products on the coating line the drying and baking ovens are insulated on all sides, allowing heat to be recycled efficiently, thereby reducing energy consumption increasing waste disposal costs and solvent emission limits have led to the conversion of high solid oil-based coatings to powder coatings Nordson Versa-Screen system can control many coating process parameters, including starting an automatic spray gun Powder coating equipment includes two sets of Nordson Excel2000 (R) spray rooms, which can be used on the same coating line for different color powder coating switching When coating complex workpieces, they need to be sprayed by hand The manual spray equipment is installed in front of the automatic spray device This effectively prevents the Faraday cage shielding effect of the powder and ensures that the amount of powder used for manual operation is not excessive safety is also important when choosing powder coating equipment, and insurance companies need equipment safety documents Paul Kerr, chairman of AmericanDesk, explains: "Nordson provides the operating manual for the entire production line." increased productivity
by increasing line speed and improving the suspension technology of the workpiece, the production efficiency of the powder coating system has been increased by 50% to 100%, and proper shelf design and workpiece suspension technology are critical "From liquid coatings to powder coatings, we redesigned the shelves and increased the density of the shelves," says Kerr use of this new shelf, resulting in a significant reduction in the demand for labor, it is estimated that the powder coating line two shifts a day than the original liquid coating line three shifts a day production volume is greater The scrap rate of the product has been significantly reduced, from approximately 10 per cent of total production to 2 per cent AmericanDesk reduces costs by increasing productivity and reducing scrap, Kerr said, "You can't judge the system based on cost and productivity alone." In addition, the quality of product coating is not possible by traditional means Our customers immediately noticed that today's coating products not only have a ceramic sheen, but also have better durability "the new powder coating system brings us environmental benefits and improves the working environment for our employees." Kerr went on to say that "the paint coating line used to be the dirtiest place in the factory, and now our powder coating line is available for people to visit"
