Our car seat frame production adopts standardized, fully automated and semi-automated manufacturing processes from raw material incoming inspection to finished product packaging. Every production step is strictly controlled to ensure high precision, stable structure, excellent durability and perfect consistency for each automotive seat frame. The complete production flow is as follows:
1. Raw Material Inspection & Cutting We use high-quality national standard cold-rolled steel sheets and high-strength steel pipes as raw materials. Before production, all steel materials are strictly inspected for thickness, hardness, flatness and surface quality to ensure no rust, deformation or cracks. Qualified steel materials are precisely cut into required sizes by professional CNC cutting machines and shearing equipment, ensuring uniform material specifications for subsequent processing.
2. Precision Stamping & Forming The cut steel plates and steel tubes are sent to large stamping machines for one-time stamping and bending forming. According to the seat frame design drawings, multiple precision stamping procedures are carried out to complete the bending, grooving, hole punching and shaping of frame parts. This process ensures uniform stress distribution, accurate hole position size and smooth overall radian of the seat frame, avoiding structural deviation and assembly errors.
3. Component Welding & Reinforcement All stamped frame parts, side brackets, mounting feet, slide rail fixing seats and reinforcing ribs are assembled and positioned manually and mechanically. Then we adopt spot welding, projection welding and full welding processes for overall welding. The welding points are dense, uniform and firm without missing welding, virtual welding or welding bubbles. Key stress-bearing positions are reinforced with multi-layer welding to greatly improve the impact resistance and load-bearing capacity of the entire seat skeleton.
4. Deburring & Polishing Treatment After welding is completed, all welding seams, cutting edges and hole positions are finely polished and deburred. We remove welding slag, sharp edges and surface blemishes to make the entire frame surface smooth and flat. This procedure effectively prevents scratching during assembly and use, and lays a good foundation for subsequent surface anti-rust treatment.
5. Surface Anti-rust & Finishing Process To solve the rust and oxidation problem of metal frames, all finished semi-finished seat frames undergo strict surface treatment, including degreasing, pickling, phosphating, rust removal and cleaning. Finally, electrostatic spraying, black electrophoresis or zinc plating is applied. The treated surface is anti-corrosion, anti-oxidation, wear-resistant and not easy to peel off, greatly extending the service life of the car seat frame in various harsh environments.
6. Assembly of Accessories We install supporting accessories according to product types, including seat slide rails, manual recliners, electric adjustment motors, fixed brackets, spring parts and limit devices. All accessories are precisely matched and installed firmly to ensure flexible sliding, smooth angle adjustment and stable locking function of the seat frame, meeting the functional requirements of manual and electric seat frames.
7. Strict Quality Testing & Inspection All finished products undergo full quality inspection before leaving the factory. Including overall size tolerance detection, welding firmness test, load-bearing pressure test, vibration resistance test, opening and closing durability test and surface quality inspection. Unqualified products will be reworked directly. Only products that fully meet automotive industry standards can enter the packaging process.
8. Professional Packaging & Shipment Qualified car seat frames are cleaned and dried firstly. Then they are wrapped with anti-wear foam, pearl cotton and waterproof plastic film, and packed in standard export cartons or wooden boxes. Strict packaging can effectively prevent extrusion deformation, surface wear and moisture rust during long-distance sea and land transportation, ensuring customers receive intact products.
