Powder coating processing price, sand hung hardware appliances spraying (certified), spraying processing provided by the Dongguan City, Sha Hong Hardware Appliance Co., Ltd.. Dongguan Sha Hong Hardware Appliance Co., Ltd. (www.dgshahong.com) is specialized in the "spray processing, electrical spraying, metal spraying, lampshades spraying, roller coating, ceramic coating" of the enterprise, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Sha. Powder coating is dusting equipment (electrostatic spray machine) to the powder coating to the surface of the workpiece, in electrostatic powder evenly adsorbed on the surface, forming a powder coating; powdery coating baked at high temperatures Grilled leveling cured into varying results (effect of different types of powder coatings) of the final coating; powder spray coating results in mechanical strength, adhesion, corrosion resistance, anti-aging spray painting process is superior processing costs Also under the same effect paint. Pretreatment process before quality directly affects the quality of the powder coating, pre-treatment is not good low friction powder coating process, resulting in the coating easy to fall off, bubbling phenomenon. Therefore, the first task must be paid. For sheet metal stamping by chemical pre-treatment method. Namely: to oil → to rust → cleaning → phosphide (or purified), etc. Most surface rust or thicker workpieces, using sand blasting, shot blasting and other mechanical methods to rust, but the mechanical descaling should ensure that the workpiece surface is clean, you can not scale. Putty. Scraping the workpiece defect extent conductive putty, smoothed electrostatic spray drying process engineering with sandpaper, you can be the next step. Protection (also known as shield cover). If some parts of the workpiece does not require a coating, can be used before the warm-up protection, such as plastic covered up to avoid spray paint. Preheat. Generally without preheating. If a thicker coating layer is required, the workpiece can be preheated to 100 ~ 160 ℃, which can increase the coating thickness.
