Technical Capabilities
Precision custom sheet metal fabrication at Honyo Prototype integrates advanced laser cutting, precision bending, and high-integrity welding to deliver components with tight tolerances, superior edge quality, and consistent repeatability. This process is ideal for low-to-mid volume production and prototyping across industrial, automotive, medical, and electronics sectors.
Our capabilities support a range of materials including aluminum, steel, and select thermoplastics such as ABS and nylon, each chosen for specific mechanical, thermal, and environmental performance. While metals are processed using laser cutting and press braking, non-conductive thermoplastics are handled with CNC routing or laser systems calibrated for polymer ablation.
Below is a summary of technical specifications by process and material:
| Process | Material | Thickness Range | Tolerance | Max Part Size | Notes |
|---|---|---|---|---|---|
| Laser Cutting | Aluminum | 0.5 mm – 6.0 mm | ±0.1 mm | 1500 mm × 3000 mm | Fiber laser; high-speed cutting with minimal HAZ |
| Laser Cutting | Steel (Mild & Stainless) | 0.5 mm – 8.0 mm | ±0.1 mm | 1500 mm × 3000 mm | Up to 8 mm with nitrogen/oxygen assist; burr-minimized edges |
| Laser Cutting | ABS | 1.0 mm – 6.0 mm | ±0.2 mm | 600 mm × 1200 mm | CO₂ laser only; edge melting controlled via parameter optimization |
| Laser Cutting | Nylon | 1.0 mm – 5.0 mm | ±0.2 mm | 600 mm × 1200 mm | Limited to unfilled grades; post-cut cleaning recommended |
| CNC Bending | Aluminum | 0.8 mm – 6.0 mm | ±0.2° / ±0.1 mm | 1500 mm length | Up to 90° standard; custom tooling available |
| CNC Bending | Steel | 0.8 mm – 6.0 mm | ±0.2° / ±0.1 mm | 1500 mm length | AMADA press brakes with CNC backgauging |
| Welding | Aluminum | 1.0 mm – 6.0 mm | ±0.5 mm fit-up | Full form welding | TIG or MIG with argon shielding; post-weld deburring available |
| Welding | Steel | 1.0 mm – 6.0 mm | ±0.5 mm fit-up | Full form welding | MIG/TIG; optional post-weld painting, powder coating, or passivation |
Note: Thermoplastics (ABS, Nylon) are not suitable for welding via traditional metal methods. Joining is performed using solvent bonding, ultrasonic welding, or mechanical fasteners. All metal parts undergo deburring, and optional surface finishes include anodizing (aluminum), plating, powder coat, or passivation.
From CAD to Part: The Process
Honyo Precision Custom Sheet Metal Process Overview
Honyo Prototype executes precision custom sheet metal fabrication through an integrated digital workflow designed for speed, accuracy, and manufacturability. The process begins with a client uploading a native CAD file (STEP, IGES, or native SOLIDWORKS) to our secure portal. Our proprietary AI-driven quoting engine immediately analyzes geometric complexity, material requirements, and tolerance specifications against real-time machine capabilities and material inventory. This system generates a detailed quote within 2 hours, including cost breakdown, lead time, and critical manufacturability flags—such as minimum bend radii, hole-to-edge distances, or potential laser cutting heat-affected zone risks—based on our ISO 9001-certified process libraries.
Design for Manufacturability Integration
Following quote acceptance, our engineering team conducts a formal DFM review within 24 hours. This is not a gatekeeping step but a collaborative optimization phase where we propose actionable revisions to enhance yield and precision. For example, we might suggest coining instead of air bending for ±0.05mm flatness requirements or adjusting kerf compensation for 0.8mm stainless steel laser cuts. Clients receive annotated 3D models with change justifications, and all modifications require explicit approval before proceeding. This phase reduces downstream rework by 65% based on 2023 production data.
Precision Production Execution
Approved designs move to production on our automated cell:
Material Verification: Incoming stock undergoes spectrometer analysis and thickness validation per ASTM A956
Nesting & Cutting: AI-optimized nesting drives Amada LC-2415NT fiber laser systems with ±0.1mm positional accuracy
Forming: TruBend 7030 press brakes with CNC-controlled backgauges achieve ±0.25° angular repeatability
Secondary Operations: Deburring via automated brush systems and precision tapping per ISO 2768-mK
Quality Assurance and Delivery
Every batch undergoes first-article inspection (FAI) per AS9102 standards, with CMM reports for critical features. In-process checks occur at 500-unit intervals for runs exceeding 2,000 pieces. Final packaging includes anti-corrosion VCI paper and serialized traceability tags linking to digital quality records. Shipments via DHL/FedEx include real-time GPS tracking, with delivery confirmation triggering automated archival of all process data to the client’s secure portal for audit compliance. This closed-loop system ensures 99.2% on-time delivery for precision sheet metal components under 24-inch dimensions.
