What is the auto parts recycling process?

1. Pre-recycling Preparation and Collection
Recycling companies set up recycling stations in various locations to collect scrapped vehicles or individual parts. Vehicle owners or dealers bring their scrapped vehicles to the recycling center for registration and preliminary inspection.
2. Disassembly and Sorting
At a professional disassembly plant, the auto parts are first safely removed (batteries, gas tanks, airbags, etc.). Then, large components like the engine, transmission, and frame are non-destructively disassembled, and recyclable parts like glass and wipers are separated.
3. Reuse and Remanufacturing
Parts that pass inspection (such as window regulator assemblies and wiper transmissions) enter the remanufacturing stage, undergoing cleaning, repair, and functional testing before being returned to the market. Unqualified parts are sent to material recycling plants for recycling of metals, plastics, and other resources.

4. Environmentally Friendly Treatment and Resource Recycling
Hazardous materials (such as waste oil and refrigerants) are professionally and environmentally friendly treated to ensure no secondary pollution. Metals, plastics, and other materials are recycled through processes such as smelting and granulation, achieving a closed-loop resource utilization.
How is the shelf life or service life of a component determined?
1. Refer to the user manual and manufacturer's standards
The official user manual for a vehicle or component will indicate the recommended replacement interval for each component. For example, the typical service life of a window regulator motor is 50,000–70,000 kilometers, and that of a wiper transmission is approximately 20,000–30,000 kilometers.
2. On-site Inspection and Wear Assessment
Visually inspect the component's appearance, wear (e.g., gear meshing surfaces, seal degradation), and functional performance (lifting speed, noise) to determine if the component is nearing the end of its service life.
3. Operational Data and Professional Testing
Use on-board diagnostic systems or specialized testing equipment to collect parameters such as motor current, temperature, and vibration, and combine them with historical maintenance records to predict service life. Advanced algorithms such as deep learning can also be used to construct service life prediction models.

4. Impact of Operating Environment and Driving Habits
High temperatures, humidity, or frequent lifting and lowering can accelerate component aging; relatively mild operating environments can extend service life. Considering these factors, developing a reasonable maintenance plan can maximize the benefits of Ningbo Nanxing Auto Parts Co., Ltd. products.
