Abstract
The invention relates to an automatic powder injection line production process. Workpieces after electrophoresis and cleaning are hung for water blowing and baking, and then the cleaned workpieces are placed in an automatic powder injection line for powder coating, wherein the chain speed of the automatic powder injection line is 24 revolutions per minute, the power injection quantity is 0.2 MPa, powder injection weighing ranges from 1.2kg to 1.6 kg, baking time is 30-40 minutes, and the baking temperature is between 215 DEG C and 225 DEG C; finished product inspection, hardness testing and smog testing are sequentially carried out on the workpieces to obtain products which meet production requirements. According to the automatic powder injection line production process, drying and baking for the workpieces can be automatically completed before powder injection processing, powder injection is automatically conducted on the workpieces during powder injection coating, quality of products is improved, and the production effectiveness of the products is improved.
