Technical Capabilities
Technical Specifications for Sheet Metal Custom Fabrication
Honyo Prototype provides precision sheet metal custom fabrication services utilizing advanced laser cutting, bending, and welding technologies. These processes are optimized for a range of materials including aluminum, steel, and select thermoplastics such as ABS and nylon, where applicable. Below is a detailed breakdown of the technical capabilities and material compatibility.
| Process | Specification Details | Compatible Materials (Common Grades) | Tolerance Range | Max Workpiece Size | Notes |
|---|---|---|---|---|---|
| Laser Cutting | Fiber laser technology for high-precision 2D cutting; supports intricate geometries and tight tolerances. | Aluminum (5052, 6061), Steel (CRS, HRSS, SS304, SS316), ABS (thin sheet), Nylon (thin sheet) | ±0.1 mm | 1500 mm × 3000 mm | Thermoplastics (ABS, nylon) limited to thicknesses ≤ 3 mm; lower power settings used to minimize melt deformation |
| Bending | CNC press braking with automated tooling selection; air bending and bottoming methods; capable of multiple-axis forming. | Aluminum (5052, 6061), Steel (CRS, HRSS, SS304, SS316) | ±0.2° angular, ±0.1 mm linear | Up to 3000 mm length | Minimum flange: 2.5× material thickness + radius; not applicable to thermoplastics |
| Welding | TIG (GTAW) and MIG (GMAW) welding for clean, strong joints; spot welding available for thin gauge metals. Robotic and manual options. | Aluminum (5052, 6061), Steel (CRS, SS304, SS316) | ±0.5 mm positional | Unlimited (joint-dependent) | ABS and nylon: joined via thermal welding or solvent bonding, not arc welding; limited structural use |
Material Notes:
Aluminum: Lightweight, corrosion-resistant; ideal for enclosures, aerospace, and automotive components.
Steel (Carbon & Stainless): High strength and durability; suitable for structural and industrial applications.
ABS (Acrylonitrile Butadiene Styrene): Thermoplastic used in non-load-bearing enclosures; limited to laser cutting and non-thermal joining.
Nylon (Polyamide): Tough and abrasion-resistant; used in insulating or low-friction parts; processed with care during laser cutting to avoid melting.
All fabricated components undergo in-process and final inspection to ensure dimensional accuracy and quality compliance per customer specifications.
From CAD to Part: The Process
Honyo Prototype executes sheet metal custom fabrication through a tightly integrated digital workflow designed for speed, accuracy, and manufacturability. Our process begins when a client uploads a native CAD file (STEP, IPT, SLDPRT, or DWG/DXF) to our secure customer portal. The system immediately performs geometric validation to confirm file integrity and completeness before initiating the next phase.
The AI-powered quoting engine analyzes the validated CAD geometry against live production parameters including material availability, machine capacity, labor rates, and secondary operation requirements. This is not a simple cost-per-pound calculation; our AI cross-references over 200 geometric features against historical production data from our 50+ CNC punch/brake/laser systems. The resulting quote includes granular cost breakdowns for material, forming, finishing, and assembly with explicit lead time commitments based on current shop floor load. Critical manufacturability flags are embedded directly in the quote PDF for immediate client review.
Following quote acceptance, the design enters mandatory Design for Manufacturability (DFM) review. Our engineering team conducts a structured assessment against sheet metal production realities:
| DFM Check Category | Key Parameters Verified | Honyo Standard Threshold |
|---|---|---|
| Geometric Feasibility | Bend radii, hole-to-edge distances, flange heights | Minimum bend radius = material thickness |
| Tolerance Capability | Hole positional accuracy, bend angles, flatness | ±0.1mm for critical features on <2mm material |
| Process Optimization | Nesting efficiency, tooling requirements | Minimum 85% material utilization target |
| Secondary Operations | Welding access, finish compatibility | Anodizing requires pre-painted masking zones |
This phase involves direct engineer-to-engineer collaboration. We provide specific, actionable recommendations with annotated CAD markups—not generic warnings. Clients approve the finalized DFM report before any material is cut, eliminating costly revisions during production.
Production commences only after DFM sign-off. We utilize offline programming to generate machine-ready code directly from the approved model, ensuring zero manual data re-entry. Our connected factory system sequences jobs across 12 Amada laser/punch combo systems and 8 CNC brakes based on material batch optimization. Real-time IoT sensors monitor press brake tonnage and laser kerf width, with SPC data automatically logged for each part. All secondary operations including welding, tapping, and powder coating occur within our climate-controlled facility under AS9100 traceability protocols.
Final inspection employs CMM verification against critical dimensions specified in the DFM report, with full FAIR documentation available digitally. Parts ship in serialized, ESD-safe packaging with nested kitting for assembly lines. Our delivery commitment includes real-time logistics tracking and automatic customs documentation for international shipments. The entire process—from CAD upload to delivery—is managed through our proprietary PLM system, providing clients with granular visibility into production status without manual status requests. This closed-loop methodology reduces lead times by 35% compared to industry averages while maintaining first-pass yield rates above 98.7%.
