Technical Capabilities
The term “sheet metal China” typically refers to sheet metal fabrication services offered by manufacturers in China, known for high-volume, cost-effective production with competitive technical capabilities. Below are the typical technical specifications for sheet metal fabrication processes—laser cutting, bending, and welding—commonly available from Chinese manufacturing partners. The materials listed include Aluminum, Steel, ABS, and Nylon, though note that ABS and Nylon are not metals and are generally processed using different methods such as CNC routing or plastic laser cutting, not traditional sheet metal techniques.
| Process | Material Compatibility | Thickness Range | Tolerance | Max Part Size | Notes |
|---|---|---|---|---|---|
| Laser Cutting | Aluminum, Steel | 0.5 – 25 mm | ±0.1 – ±0.2 mm | 1500 x 3000 mm | High-precision cutting; fiber lasers used for metals; not ideal for ABS/Nylon due to thermal deformation |
| ABS, Nylon (plastic sheets) | 1 – 10 mm | ±0.2 mm | 1200 x 2400 mm | CO2 laser recommended; risk of melting or burring; not classified as sheet metal processing | |
| Bending | Aluminum, Steel | 0.8 – 16 mm | ±0.2° angular, ±0.1 mm | Up to 3000 mm length | Performed on CNC press brakes; minimum flange ≥ 2× material thickness + 1 mm |
| ABS, Nylon | Not typically bent | N/A | N/A | Thermoplastics like ABS/Nylon are formed via heating, not V-bending; not standard in sheet metal shops | |
| Welding | Aluminum, Steel | 0.8 mm and above | ±0.5 mm positional | No hard limit | TIG, MIG, spot welding available; cosmetic grinding optional; full weld penetration typical for structural parts |
| ABS, Nylon | Not applicable | N/A | N/A | Joined via adhesive bonding, ultrasonic welding, or solvent welding; not compatible with metal welding techniques |
Notes on Material Use:
Aluminum (e.g., 5052, 6061, 7075): Lightweight, corrosion-resistant; excellent for laser cutting and welding with proper shielding gas.
Steel (e.g., SPCC, Q235, SS304): Common in carbon and stainless forms; highly weldable and bendable; mild steel responds well to all three processes.
ABS & Nylon: These are thermoplastic polymers. While they can be cut with lasers (CO2), they are not suitable for bending on standard press brakes or arc welding. They fall outside traditional sheet metal fabrication and require separate plastic processing workflows.
Manufacturers in China often integrate both metal and plastic processing, but it is critical to differentiate between sheet metal and plastic fabrication lines to ensure process accuracy and part quality.
From CAD to Part: The Process
Honyo Prototype delivers precision sheet metal fabrication from China through an integrated digital workflow designed for speed, accuracy, and manufacturability. Our end-to-end process eliminates traditional quoting bottlenecks while ensuring rigorous quality control. Below is the technical sequence:
CAD Upload
Clients initiate the process by uploading native CAD files (STEP, IGES, DWG, or native formats like SolidWorks) via our secure portal. The system validates file integrity, extracts critical geometric data—including material type, thickness, bend radii, hole patterns, and surface finish requirements—and auto-populates metadata for downstream systems. This eliminates manual data entry errors common in legacy quoting processes.
AI-Powered Instant Quoting
Our proprietary AI engine analyzes the CAD geometry against real-time production parameters from our Shenzhen and Dongguan facilities. It calculates material utilization, machine time (turret punching, laser cutting, press brake operations), secondary processes (welding, tapping, finishing), and logistics costs. The AI cross-references historical production data for similar geometries to predict potential DFM issues, generating a preliminary quote within 90 seconds. This quote includes baseline lead times and cost drivers but is flagged for mandatory engineering review.
Engineer-Validated DFM Analysis
All AI quotes undergo human validation by our APQP-certified manufacturing engineers. They perform a formal Design for Manufacturability review using Siemens NX software, checking:
Bend sequence feasibility and tooling clearance
Minimum flange lengths relative to material thickness
Hole-to-edge distances to prevent deformation
Weld accessibility and distortion risks
Surface finish compatibility with material grade
The engineer provides actionable feedback via annotated PDFs within 4 business hours, suggesting geometric optimizations that reduce cost without compromising function. Client approval of the DFM report is required before production release.
Production Execution
Approved designs move to our ISO 9001-certified facilities where digital work orders sync directly to machines:
Laser cutting on Bystronic 10kW fiber systems (±0.1mm tolerance)
Turret punching on Amada EMK 360 (0.5–6mm thickness range)
CNC press braking with automatic angle correction (±0.5° accuracy)
In-process CMM verification at critical stages (e.g., post-bending, pre-welding)
All material certifications (RoHS, MTRs) and process documentation are digitally tracked in our MES platform.
Quality-Controlled Delivery
Final inspection includes:
Full-spectrum dimensional reporting against GD&T callouts
Coating thickness validation (e.g., 25–35μm for powder coat)
Salt spray testing for corrosion-resistant finishes (per ASTM B117)
First-article inspection reports (FAIR) packaged with shipments
Orders ship via DHL/FedEx with real-time tracking; standard lead time is 7–10 business days from DFM approval. Every shipment includes a digital quality dossier accessible via client portal.
Process Efficiency Comparison
| Stage | Traditional Vendor | Honyo Prototype |
|———————-|——————-|—————-|
| Quote Turnaround | 3–5 business days | <2 hours (AI) + 4h DFM review |
| DFM Revision Cycles | 2–3 iterations | ≤1 iteration (92% first-pass yield) |
| Production Lead Time | 12–15 days | 7–10 days |
