Technical Specifications for Unique Sheet Metal Fabrication

The term “unique sheet metal” refers to custom-engineered sheet metal components that require precision processing through laser cutting, bending, and welding. These parts often involve complex geometries, tight tolerances, and multi-material integration. Below are the technical specifications for key fabrication processes with emphasis on compatible materials including Aluminum, Steel, ABS, and Nylon.

Parameter	Laser Cutting	Bending	Welding
Material Compatibility	Aluminum (5052, 6061), Steel (Mild, Stainless 304/316), ABS (limited), Nylon (limited)	Aluminum, Steel (Mild, Stainless) — ABS and Nylon not suitable for bending	Aluminum (TIG/MIG), Steel (MIG/Stick/TIG) — ABS and Nylon not weldable via traditional methods
Thickness Range	0.5 mm – 12 mm (Aluminum & Steel); ABS/Nylon: up to 6 mm (with CO₂ laser)	0.8 mm – 6 mm (Aluminum & Steel); excludes thermoplastics	1.0 mm – 10 mm (Aluminum & Steel); thermoplastics require specialty joining
Tolerance	±0.1 mm (precision cut with fiber laser)	±0.2° angular tolerance; ±0.1 mm linear bend placement	±0.5 mm positional tolerance; post-weld distortion ≤ 0.5 mm per 100 mm
Edge Quality	Burr-free edges with minimal heat-affected zone (HAZ)	Smooth, crack-free bends with controlled grain direction	Smooth, spatter-controlled weld beads; post-clean acceptable
Process Notes	Fiber laser preferred for metals; CO₂ laser used for thicker non-metals	Requires tool-specific punch/die sets; minimum bend radius = 1× material thickness	Gas shielding (Ar for Al, CO₂/Mixed for Steel); fixturing critical
Surface Finish	Matte finish; optional deburring or passivation for corrosion resistance	Can retain mill finish; anodizing/painting post-forming	Requires grinding/polishing; post-weld coating often applied
Joining Alternatives for ABS/Nylon	Cut via CO₂ laser; no post-laser welding	Not applicable — thermoforming preferred for shaping	Ultrasonic welding, solvent bonding, or mechanical fasteners required

Notes:
Aluminum and Steel are primary materials for full-process fabrication (cut, bend, weld).
ABS and Nylon are thermoplastics typically not classified as sheet metal but may be included in hybrid assemblies. They are process-limited: laser cutting possible with CO₂ systems, but bending and traditional welding are not feasible.
For mixed-material designs, mechanical fastening or adhesive bonding is recommended to integrate thermoplastics with metal components.

From CAD to Part: The Process

Honyo Prototype Unique Sheet Metal Manufacturing Process

Honyo Prototype specializes in low-volume, high-complexity sheet metal fabrication where conventional quoting systems fail. Our “unique sheet metal” designation applies to parts featuring extreme geometries, tight tolerances, unconventional materials, or integrated secondary processes. The end-to-end workflow is engineered for precision and speed without sacrificing manufacturability.

CAD Upload
Customers submit native 3D CAD files (STEP, IPT, SLDPRT) via our secure portal. Unlike generic platforms, our system immediately parses geometric complexity, material specifications, and critical features such as micro-perforations, deep draws exceeding 3x material thickness, or compound bends below 0.5mm radii. File validation checks for non-manifold edges and ensures tolerance callouts align with ASME Y14.5 standards before progression.

AI-Powered Quoting Engine
Uploaded CAD data feeds our proprietary AI quoting system, trained on 12,000+ historical builds. The engine dynamically calculates costs by analyzing:
Material utilization efficiency considering laser kerf and nest collision risks
Secondary operation sequencing (e.g., welding before or after anodizing)
Geometric complexity penalties for features like embedded threads in thin-gauge aluminum
Real-time material market fluctuations for exotics (e.g., Inconel 625, beryllium copper)
Quotes include granular cost breakdowns and highlight high-risk features requiring DFM intervention, typically generated within 90 minutes.

Engineer-Led DFM Analysis
All unique parts undergo mandatory DFM review by senior sheet metal engineers. This phase identifies and resolves non-manufacturable features through collaborative iteration. Critical focus areas include:

Feature Type	Common Issue	Honyo Resolution Path
Bend Geometry	Interference in multi-bend sequences	Redesign bend order or add relief cuts
Thin Features	Buckling in <0.8mm sections	Recommend stiffening ribs or material upgrade
Tight Tolerances	±0.05mm on formed edges	Propose post-form CNC milling step
Material Constraints	Springback in high-strength alloys	Adjust bend allowance via FEA simulation

Engineers provide annotated 3D models with actionable suggestions, maintaining design intent while ensuring producibility. Approval requires explicit sign-off from both Honyo and the customer.

Precision Production
Approved designs move to our dedicated unique-parts cell featuring:
Hybrid laser-turret systems (Amada LC-3015 with 6kW fiber laser + 36-station turret) for mixed-technology optimization
In-process CMM validation at critical stages (e.g., after primary forming, pre-finishing)
Material traceability via barcode tracking from coil to shipment
Environmental controls for sensitive finishes (e.g., humidity-stable anodizing for aerospace alloys)
All welds undergo 100% visual inspection with AWS D17.1 compliance documentation; critical structural welds receive ultrasonic testing.

Certified Delivery
Final inspection packages include:
First-article inspection report (FAIR) with 32-point dimensional verification
Material test certificates (MTRs) with full chemical and mechanical properties
Process validation records for secondary operations (e.g., torque values for captive nuts)
Packaging engineered for part geometry (e.g., custom foam cradles for warped assemblies)
Shipments include serialized tracking with real-time logistics updates and meet ITAR/EAR compliance requirements where applicable. Average lead time from DFM approval to delivery is 12–18 business days, contingent on feature complexity.

This integrated process ensures technically challenging sheet metal components achieve first-pass yield rates exceeding 92% while maintaining full traceability from digital model to certified physical part.
