Precision Sheet Metal Fabrication Diversified Processing Technologies

2025-07-31

Precision Sheet Metal Fabrication's diverse processing technology system is revolutionizing industry standards through intelligent and hybrid processes. The following are key technology categories and innovation directions:

1. Intelligent Cutting and Forming Technology

Laser Cutting: A 12kW fiber laser can process 40mm thick steel plates with a contour cutting accuracy of ±0.01mm, supporting the processing of multiple materials such as stainless steel and aluminum alloys.
AI Bend Compensation: A deep learning algorithm predicts material springback in real time, controlling bend angle errors within ±0.1°, making it suitable for multi-pass forming of special-shaped parts.
Deep Drawing: Aluminum alloy drawing technology with a depth ratio of 2.5:1 is used in the manufacture of EV battery cases, combined with hydroforming to improve material flowability.

2. Hybrid Processing System

Laser Punching and Welding Machine: Integrating stamping and laser welding functions, this machine reduces machine footprint by 67%, enabling efficient production of components such as door hinges.
Electromagnetic Assisted Drawing: Using electromagnetic fields to reduce the friction coefficient by 40%, addressing cracking during forming in high-strength steel.
Metal Spinning: Suitable for seamless forming of axisymmetric parts such as turbine casings, with a surface roughness of Ra ≤ 0.8μm.

3. Surface Treatment and Inspection

Super-Mirror Polishing: Stainless steel treated with glass bead blasting achieves a surface finish of Ra ≤ 0.05μm, meeting medical device-grade finish requirements.
Intelligent Welding Error Correction: Laser welding systems automatically identify and correct weld deviations, reducing spatter by 90%, making them suitable for precision electronic housings.
Digital Twin Quality Inspection: Real-time simulation of production line energy consumption and defect prediction reduces rework rates by 40%.

4. Flexible Manufacturing Trends

Single-Part Customized Production: Through modular molds and rapid changeover technology, small-batch orders can be made at the same cost as large-scale production.
3D Printing Hybrid Process: Combining topology optimization design with metal additive manufacturing reduces the development cycle of complex structural parts by 50%.

Current technological evolution is driving sheet metal processing towards high integration and low energy consumption, with particular application in new energy and high-end equipment.
