Design principles
1. Production line design, selection process equipment to ensure achieving technology and various technical parameters;
2. The overall layout design, production of complete production process to consider the rationality; Equipment layout coordination, neat, beautiful, operation, maintenance;
3. The scheme determination of production line to consider the technical sophistication, fully meet the product quality requirements;
4. All devices ensure the production line advanced, practical, reliable and safe; Main equipments and components choose domestic well-known manufacturers, parts are imported products;
5. Line all homemade equipment in structural design by using common standard spare and standard as far as possible, in order to improve the standardization level, and fully considering the improvement production work environment and labor health conditions, implement state and industry related standards and safety measures;
6. To meet the buyer based on the various technical requirements, minimizing the one-time investment to reduce energy consumption to reduce the production cost.
Powder coating line technological process:
| 1. According to the characteristics of the products, spraying production line adopts continuous type, can not only enhance the production efficiency and lower investment. |
| 2. Powder spraying as high-grade surface coating process means, coatings manufacturers and coatings manufacturers, device manufacturers, every link all need to have strict quality control to ensure quality of coating work pieces. |
| 3. Powder curing oven uses gas heating and hot air circulation to guarantee the even temperature, while also ensuring curing quality. |
| 4. Work piece hangs way: according to different size, adopting secondary work piece overall double point hanging fixture, choose different spacing to pack hanging. |
