Technical Capabilities
As a Senior Manufacturing Engineer at Honyo Prototype, I must clarify a critical misconception in your query upfront: ABS and nylon are not metals—they are thermoplastic polymers. They are not processed using laser cutting, bending, or welding in the context of metal fabrication. These processes are exclusively for metallic materials.
- ABS/Nylon: Used in plastic manufacturing (e.g., injection molding, 3D printing, or plastic-specific welding like ultrasonic/hot-plate welding). They cannot be “bent” like sheet metal (no plastic deformation in the metallurgical sense) and are not welded using arc/MIG/TIG processes—those methods would burn or vaporize plastics.
- Metal Fabrication: Only applies to metals and alloys (e.g., aluminum, steel, stainless steel, copper, titanium).
Corrected Scope for a Metal Fabrication Design App:
This app must focus exclusively on metallic materials (e.g., aluminum alloys, carbon steel, stainless steel). ABS and nylon have no place in this context. Below are the technical specs for a professional metal fabrication design app, tailored for laser cutting, bending, and welding—aligned with Honyo Prototype’s industrial standards and real-world manufacturing constraints.
I. Core Technical Specifications
A. Material Database & Properties
(Only for metals—ABS/nylon excluded)
| Material | Key Properties & Constraints |
|—————|———————————————————————————————-|
| Aluminum | – Alloys: 6061-T6, 5052-H32, 7075-T6
– Max Thickness: 25mm (laser), 12mm (bending)
– Thermal Conductivity: High (requires lower laser power to avoid burn-through)
– Springback: 1.5–2x higher than steel (critical for bending)
– Weldability: Requires TIG/MIG with argon shielding; prone to cracking in 7000-series alloys |
| Carbon Steel | – Grades: A36, 1018, 1020
– Max Thickness: 30mm (laser), 20mm (bending)
– Heat Affected Zone (HAZ): Significant—requires post-weld stress relief
– Rust Risk: Requires coating (e.g., powder coating) after fabrication |
| Stainless Steel | – Grades: 304, 316
– Max Thickness: 20mm (laser), 15mm (bending)
– Sensitization Risk: Intergranular corrosion if welded improperly (requires low-heat processes like TIG)
– Work Hardening: High—bending requires larger radii than carbon steel |
✅ App Requirement: Material properties must auto-adjust process parameters (e.g., laser power, bend allowance) based on alloy grade and temper.
B. Laser Cutting Specifications
(For metals only—no plastics)
| Parameter | Technical Spec |
|———————–|——————————————————————————-|
| Kerf Width | 0.1–0.3mm (adjustable per material/thickness; e.g., 0.15mm for 3mm steel, 0.25mm for 10mm aluminum) |
| Max Thickness | – Carbon Steel: 30mm
– Stainless Steel: 20mm
– Aluminum: 25mm |
| Edge Quality | – Class A: Ra ≤ 1.6μm (for visible surfaces)
– Class B: Ra ≤ 3.2μm (structural parts)
– Burn Marks: Auto-flagged for stainless steel >5mm |
| Process Constraints | – Minimum feature size: 1.5x material thickness (e.g., 1.5mm hole in 1mm sheet)
– Nesting: AI-driven optimization for material yield (min. 85% utilization)
– Cutting Speed: Auto-calibrated per material (e.g., 10m/min for 1mm steel, 2m/min for 10mm aluminum) |
⚠️ Critical Error Avoidance: The app must block ABS/nylon inputs—laser cutting plastics would release toxic fumes and damage equipment.
C. Sheet Metal Bending Specifications
| Parameter | Technical Spec |
|———————–|——————————————————————————-|
| Bend Radius | – Minimum: 1x material thickness (for 6061-T6 aluminum)
– Maximum: 10x thickness (to avoid cracking)
– K-Factor: Auto-calculated per material (e.g., 0.4 for steel, 0.45 for aluminum) |
| Tonnage Requirement | – Formula: Tonnage = (1.4 × Length × Thickness² × Tensile Strength) / (Die Width × 1000)
– App flags if tonnage exceeds machine capacity (e.g., 250T press brake max) |
| Springback Compensation | – Aluminum: +3–5° extra angle
– Stainless Steel: +2–3°
– Carbon Steel: +1–2° |
| Design Rules | – Minimum flange length: 3x material thickness
– Hole clearance: ≥2x thickness from bend line
– No sharp internal corners (min. radius = 0.5x thickness) |
D. Welding Specifications
| Parameter | Technical Spec |
|———————–|——————————————————————————-|
| Joint Types | – Butt Welds: For >3mm thickness
– Fillet Welds: Leg size ≥1.4× thinner part
– Lap Joints: Avoid for aluminum (>2mm thickness due to burn-through risk) |
| Weld Process | – TIG: Best for thin aluminum/stainless (0.5–6mm)
– MIG: For thicker steel (>3mm)
– Spot Welding: Max 2mm thickness for aluminum |
| Heat Input Control | – Aluminum: Max 1.5 kJ/mm (to prevent warpage)
– Stainless Steel: Max 1.0 kJ/mm (to avoid sensitization)
– Preheat: Required for carbon steel >10mm |
| Post-Weld Treatment | – Aluminum: Stress-relief annealing (300°C for 1 hour)
– Stainless: Pickling/passivation for corrosion resistance |
II. Cross-Process DFM Rules (Design for Manufacturability)
- Laser + Bending:
- Bending lines must be ≥2x material thickness from cut edges (to avoid distortion).
- Welding near bends: Minimum 10mm distance from bend line to prevent heat-induced cracking.
- Laser + Welding:
- Welded edges must have ≥0.5mm gap tolerance (laser-cut edges are precise but may need grinding for fit-up).
- Bending + Welding:
- Avoid welding across bend lines—welds must be placed on flat sections only.
💡 App Feature: Real-time DFM violation alerts (e.g., “Bend radius too small for 5mm aluminum—min. 5mm required”).
III. Why ABS/Nylon Are Excluded
- ABS/Nylon in “Metal Fabrication” is a fundamental error:
- Laser cutting plastics: Releases hydrocyanic acid (toxic), melts unevenly, and damages laser optics.
- “Bending” plastics: Not a metal fabrication process—plastics are thermoformed or machined.
- Welding plastics: Requires plastic-specific methods (e.g., ultrasonic welding for ABS), not arc-based welding.
- Honyo Prototype’s Protocol: We maintain strict separation between metal and plastic workflows. A single app for both would be unsafe and non-compliant with ISO 9001 standards.
IV. Recommended App Capabilities
- Interactive 3D Modeler: Drag-and-drop sheet metal parts with auto-generated bend lines, cut paths, and weld symbols.
- Material-Specific Process Simulator: Visualize heat distortion, springback, or weld bead profiles before production.
- Automated Quoting Engine: Real-time cost estimates based on material, thickness, process steps, and machine availability.
- Compliance Check: Auto-flag non-compliant designs (e.g., “Stainless steel weld without post-weld passivation—corrosion risk”).
- Machine Integration: Direct export to CNC laser cutters, press brakes, and robotic welders (e.g., Trumpf, Amada, Fronius).
✅ Final Note: If your project involves plastics (ABS/nylon), you need a separate plastic fabrication design module—not a “metal fabrication” app. At Honyo Prototype, we handle plastics via injection molding or CNC machining tools, with entirely different specs (e.g., draft angles, wall thickness uniformity).
Let me know if you’d like the plastic-specific specs for ABS/nylon—I’m happy to provide those in a follow-up. For metal fabrication, always stick to metals. Safety and precision depend on it.
