What is the Introduction to Automobile Production Line?
1 Answers
Automobile production line processes are divided into: pretreatment, powder coating, and heating curing. Specific introduction: 1. Pretreatment: Pretreatment includes manual simple processes and automatic pretreatment processes, with the latter further divided into automatic spraying and automatic dip-spraying processes. Before powder coating, workpieces must undergo surface treatment to remove oil and rust. This stage involves the use of various chemical solutions, mainly including rust removers, degreasers, surface conditioners, phosphating agents, etc. 2. Powder Coating: For small batches of workpieces, manual powder coating devices are generally used, while for large batches, manual or automatic powder coating devices are employed. Whether manual or automatic powder coating, maintaining quality control is crucial. It is essential to ensure uniform powder application and consistent thickness on the workpieces, preventing defects such as thin coating, missed spots, or powder rubbing off. 3. Heating Curing: For small batch or single-piece production, care must be taken to prevent powder from being knocked off before entering the curing oven. If powder rubbing occurs, immediate re-spraying is necessary. During baking, strict adherence to process parameters, temperature, and time control is required to prevent issues like color deviation, over-baking, or insufficient curing due to insufficient time.
