What is non-standard sheet metal processing and customization? One-sentence definition: Based on specific customer requirements, cold processing such as cutting, bending, and welding is performed on thin metal sheets (typically ≤6mm) to produce customized metal components or finished products without uniform standard specifications.

Keyword    Definition
non-standard

There is no unified size standard for countries or industries, and the approach is tailor-made without following the rules
sheet metal

For the comprehensive cold working process of metal sheets, the plate thickness remains unchanged during processing
Processing & Customization

The customer provides drawings or samples, and the factory produces according to demand, allowing small batches and multiple production runs
Typical Process Flow
Drawing Conversion → Engineers transform 3D drawings into engineering drawings, selecting materials such as SPCC cold-rolled steel, 304 stainless steel, 5052 aluminum alloy, etc
Numerical Control Cutting → Laser Cutting / Punching, with precision controllable within ±0.1mm
Numerical Control Bending → Bending Angle Tolerance ≤1°, Transforming Flat Sheets into L-Shaped, U-Shaped, Box Structures, and Other Three-Dimensional Forms
Stamping and forming → Functional details such as punching, snap-fit, and slats
Welding and Assembly → Integration of multiple components into a whole, requiring deformation control
Grinding + Surface Treatment → Powder Coating/Electroplating/Passivation, Balancing Rust Protection and Aesthetics
The difference from standard sheet metal
 Standard sheet metal  
Custom non-standard sheet metal
Specifications: Uniform dimensions, interchangeable  
No fixed specifications, one version per order
Usage: General-purpose parts (e.g., standard chassis)  Specialized parts (e.g., exclusive enclosures for specific equipment)
Production Volume: Large Batch, Small Batch/Single Piece/Multiple Batches All Accepted
Core Competence: Efficiency First, Rapid Design Response + Flexible Process Adaptation
Typical application scenarios
Automotive Manufacturing: Non-standard metal components, charging pile enclosures (This single category alone is projected to open up a market exceeding 10 billion yuan in 2024)
Electronic equipment: AI server chassis, industrial control cabinets, power distribution boxes
Medical Equipment: Customized Enclosures with Dustproof, Anti-Static, and Easy-to-Disinfect Properties
Industrial Equipment: Non-standard equipment racks, protective covers, and energy storage cabinets
Commercial Scenarios: Stainless Steel Cabinet Parts, Irregular Display Racks, etc
