II. Product Features
(I) Core Performance
1. High strength and toughness: The ferrous metal substrate gives the product excellent tensile and compressive properties. After stamping and cold working hardening, the strength is further improved, and it can withstand heavy loads and impacts, ensuring stable operation of the equipment.
2. Precision molding: The mold accuracy is controlled at ±0.05mm, the dimensional tolerance of the stamping parts is small, and it is suitable for automated assembly to ensure product consistency and interchangeability.
3. Cost advantage: Ferrous metal raw materials are easy to obtain and the stamping process is mature. Compared with other processing methods, the production cost is reduced by 20% - 30%, which is both cost-effective and practical.

(II) Feature comparison table

Features Dimension	Ferrous metal stamping parts	Other materials/process parts	Application Value
strength	Tensile strength ≥400MPa	Most are lower than this value	Heavy-duty equipment operates stably
Molding accuracy	Tolerance ±0.05mm	Difficult to achieve accuracy	Adapt to automated production lines
cost	Low raw material + process cost	Cost 15% - 25% higher	Reduce costs and increase efficiency, adapt to mass production
Weather resistance	Excellent corrosion resistance after surface treatment	Some materials are susceptible to corrosion	Outdoor / long-term service in harsh working conditions

After surface galvanizing, painting and other treatments, the weather resistance can also be improved, and it is suitable for harsh working conditions such as outdoor and high humidity.
III. Product Details
(I) Process Flow
1. Mold Design: Use CAD software to design the mold, including the punch and die, and after CNC processing and heat treatment, ensure the hardness of HRC58-62 and the service life of more than 500,000 times.
2. Plate Pretreatment: Flatten and level the black metal plate, remove oil and rust, and ensure the quality of stamping.
3. Stamping Forming: On a 100-500T press, complete the blanking, punching, bending and other processes, and monitor the pressure in real time to avoid cracking and deformation of the plate.
4. Post-processing: Deburring, grinding, optional galvanizing (anti-corrosion), spraying (beautiful + protection) and other surface processes to improve product performance and appearance.
(II) Applicable scenarios
Automobile manufacturing: production of chassis brackets and body reinforcements, using high strength to ensure vehicle safety, and precise dimensions to fit the whole vehicle assembly.
Mechanical equipment: manufacturing gearbox housings and hydraulic valve plates, relying on toughness and precision to ensure the stability of equipment transmission and control functions.
Electrical industrial control: processing control cabinet housings and busbar accessories, and ensuring the safe operation of electrical systems through protection and connection structures.
(III) Quality control
Adopt the "three inspections" system: first piece inspection (confirming mold and process parameters), patrol inspection (sampling size and appearance every 2 hours), and finished product inspection (full inspection of key dimensions and random inspection of mechanical properties). The tensile strength is verified by a tensile testing machine, and the dimensional accuracy is controlled by a three-coordinate measuring instrument to ensure that the product meets standards such as GB/T 13914, laying a solid quality foundation for industrial equipment and helping enterprises to produce efficiently.
