Technical Capabilities

Custom sheet metal bending involves a series of precision fabrication processes including laser cutting, bending, and welding. These operations are performed to transform flat sheet materials into complex structural components according to engineering specifications. The process begins with laser cutting for accurate profile definition, followed by CNC press braking for precise angular bends, and completed with welding when assemblies require permanent joints. Below are the technical specifications for each process, including compatible materials such as aluminum, steel, ABS, and nylon.

Welding Process	TIG (preferred for aluminum and stainless), MIG (for carbon steel), Spot Welding
Joint Types	Butt, fillet, edge, corner, and lap joints
Penetration Control	Adjustable current and pulse settings for thin to thick materials
Heat Input	Minimized to reduce warping; back purging used for critical stainless joints
Post-Weld Treatment	Grinding, polishing, or passivation (for stainless); inspection per ISO 5817
Filler Materials	ER4043/ER5356 (Aluminum), ER70S-2 (Steel), no filler for resistance welding
Materials Supported	Aluminum, Mild Steel, Stainless Steel (weldable grades); ABS and Nylon – not weldable via arc processes; may use ultrasonic or hot plate welding separately

Material Compatibility Summary

Material	Laser Cuttable	Bendable	Weldable (Arc)	Notes
Aluminum	Yes	Yes	Yes	Excellent for TIG welding; reflective, requires high-power fiber laser
Steel (Mild/Stainless)	Yes	Yes	Yes	Mild steel easily welded; stainless requires proper shielding gas
ABS	Yes (CO₂)	Yes (limited)	No (arc)	Thermoplastic; can be glued or ultrasonically welded; prone to melting
Nylon	Yes (CO₂)	Yes (limited, with preheating)	No (arc)	Hygroscopic; requires drying; welding via hot gas or ultrasonic methods only

These technical parameters ensure high repeatability, dimensional accuracy, and structural integrity in custom sheet metal fabrication projects at Honyo Prototype. Process selection is optimized based on material type, part geometry, and end-use requirements.

From CAD to Part: The Process

Honyo Prototype Custom Sheet Metal Bending Process Overview

Honyo Prototype delivers precision custom sheet metal bending through a streamlined, technology-driven workflow designed for speed, accuracy, and manufacturability. Our process begins with seamless digital integration and concludes with certified delivery, ensuring client requirements are met without compromise.

Upload CAD
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, DXF, DWG, SLDPRT) via our secure online portal. Our system performs immediate automated validation checks for file integrity, unit consistency, and geometric completeness. Invalid or ambiguous submissions trigger an instant notification with specific error details, minimizing initial delays. Validated files proceed directly into the quoting engine without manual intervention.

AI-Powered Instant Quote
Leveraging proprietary AI algorithms trained on 15+ years of production data, our system analyzes the CAD geometry, material specifications, and tolerances to generate a comprehensive quote within 90 seconds. The AI evaluates bend sequences, tooling requirements, secondary operations, and material utilization to calculate accurate material costs, machine time, and labor. Critical parameters like minimum flange lengths, internal radii, and proximity to edges are cross-referenced against machine capabilities. The output includes a detailed cost breakdown, lead time estimate, and preliminary feasibility flag.

Engineered DFM Analysis
All quotes undergo mandatory Design for Manufacturability (DFM) review by our senior manufacturing engineering team. Unlike automated-only systems, this phase combines AI insights with human expertise to identify potential issues such as:
Excessive bend counts requiring secondary operations
Non-standard tooling needs impacting cost
Critical dimension conflicts with achievable tolerances (±0.1mm typical for bends)
Material grain direction implications for strength
Our engineers provide specific, actionable recommendations via annotated 3D models and written reports. Clients receive alternative solutions—not just problem notifications—to maintain design intent while optimizing cost and lead time. Client approval of the DFM report is required before production release.

Precision Production Execution
Approved designs move to our CNC press brake cells featuring Amada HG and Bystronic machines with 100-300 ton capacity and 0.05mm repeatability. Each job includes:
First-article inspection against all critical dimensions using calibrated CMMs
In-process checks at 50% and 100% completion for multi-part runs
Real-time machine monitoring for tonnage, angle consistency, and backgauge positioning
Material traceability maintained via barcoded work orders from raw stock to finished part
Secondary operations like deburring, tapping, or welding are sequenced within the same workflow to prevent handling damage.

Certified Delivery
Final parts undergo full dimensional verification against the approved drawing. Components are cleaned, passivated (if stainless), and packaged using anti-static materials with custom foam cradling to prevent deformation during transit. Every shipment includes:
Certificate of Conformance with material mill test reports
FAI report documenting all inspected characteristics
As-built dimensional data package
Traceable job documentation for audit compliance
Standard lead time is 5-7 business days from DFM approval, with expedited options available.

Process Efficiency Comparison
Our integrated workflow eliminates traditional handoffs between quoting, engineering, and production teams. This reduces typical industry quoting-to-approval cycles by 65% while maintaining rigorous quality control.

Phase	Traditional Manual Process	Honyo Prototype Process
Quote Generation	2-5 business days	<90 seconds
DFM Resolution	3-7 days (multiple iterations)	24 hours (single iteration)
First-Article Approval	Post-production	Pre-series production
Tolerance Adherence Risk	High (reactive correction)	Low (proactive DFM mitigation)
