Sheet Metal Processing Technology and Process for Automated Equipment Housings：
1. Core Processing Technology
--Laser Cutting: Utilizes a 3kW fiber laser for precise cutting, achieving a cutting accuracy of ±0.1mm, suitable for materials such as stainless steel and aluminum alloys.
--CNC Bending: 200-ton press brakes support bends up to 4 meters long, enabling multi-pass custom-shaped forming of 6mm steel plates.
--Pressure Riveting: Automated pressure riveting ensures strong connections, suitable for load-bearing structures such as cabinet frames.
2. Typical Process Flow
--Material Pretreatment: Fully automatic deburring machines provide brushed polishing to enhance the surface quality of stainless steel.
--Precision Forming: CNC press brakes achieve complex angle control (±0.5° accuracy).
--Automated Welding: Robotic welding systems ensure weld strength, with a flatness tolerance of ≤0.05mm.
--Surface Treatment: Powder coating enhances weather resistance of equipment housings, maintaining a long-lasting, like-new finish.
3. Industry Application Cases
--Energy Storage Device Housing: Vertical Machining Center Enables Processing of Ultra-Large Components (6m x 3m x 2m)
--Automated Cabinet: Laser Cutting and Riveting Combine to Achieve High-Precision Housing Manufacturing
--Medical Device Housing: 304 Stainless Steel Laser Cutting, Bending, and Welding to Meet Medical-Grade Cleanroom Requirements
4. Quality Inspection Standards
--Coordinate Measurement: Verifies Mounting Surface Flatness to 0.05mm
--Film Thickness Testing: Post-Spray Coating Thickness Controlled to 30-80μm
--Pore Detection: Permanent Magnet Contact with a Magnetic Switch Determines the Acceptability of Sheet Metal Holes

Sheet Metal Fabrication is a comprehensive cold processing process for metal sheets (usually less than 6mm), including shearing, punching/cutting/compositing, folding, riveting, splicing, forming (such as automobile bodies), etc. Its distinctive feature is that the thickness of the same part is consistent.
MoreSheet metal components are light in weight, small in processing volume, easy to cut and weld, and can manufacture large and complex components with standardized shapes for easy automatic processing.
MoreSheet metal processing has been widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones, and MP3 players, sheet metal components is an essential component.
