Technical Capabilities

Custom sheet metal boxes are precision-engineered enclosures manufactured using advanced fabrication techniques including laser cutting, CNC bending, and welding. These processes ensure tight tolerances, clean edges, and structural integrity. While aluminum and steel are primary materials for sheet metal fabrication, ABS and nylon are non-metallic alternatives typically used in machined or molded enclosures rather than traditional sheet metal work. Below is a detailed technical specification table outlining key parameters for custom sheet metal boxes with a focus on laser cutting, bending, and welding.

Parameter	Laser Cutting	Bending	Welding	Compatible Materials (Typical)
Process Type	Fiber or CO₂ laser for high-precision cutting	CNC press braking with tool-specific forming	MIG, TIG, or spot welding for strong joints	Aluminum, Steel
Tolerances	±0.1 mm (typical)	±0.2° angular, ±0.05 mm linear	±0.3 mm joint alignment	Aluminum, Steel
Material Thickness Range	0.5 mm – 25 mm (Aluminum), 0.5 mm – 20 mm (Steel)	0.8 mm – 12 mm (Aluminum), 0.8 mm – 16 mm (Steel)	0.8 mm – 10 mm (Aluminum), 1.0 mm – 12 mm (Steel)	Aluminum (e.g., 5052, 6061, 7075), Steel (e.g., CRCA, Galvanized, Stainless 304/316)
Edge Quality	Burr-minimized, oxide-free edges with dross control	Smooth bends with controlled bend radius (min. 1× thickness)	Clean weld seams; post-weld grinding optional	Aluminum, Steel
Minimum Feature Size	Hole diameter ≥ material thickness	Inside bend radius ≥ 0.8× material thickness	Weld gap ≤ 0.2 mm recommended	Aluminum, Steel
Surface Finish Options	As-cut, anodized (Al), powder coated, passivated	Deburred, sanded, or polished post-bend	Ground, brushed, or coated post-weld	Aluminum, Steel
Non-Metallic Compatibility	Not applicable (laser cutting possible but not standard for sheet metal boxes)	Not applicable (thermoplastics like ABS/Nylon do not bend like sheet metal)	Not applicable (plastic welding is a separate process)	ABS, Nylon (used in non-metallic enclosures via machining or molding)

Notes:
Aluminum and steel are the standard materials for laser cutting, bending, and welding in sheet metal box fabrication.
ABS and nylon are thermoplastics; they are not suitable for traditional sheet metal processes. These materials are typically used in injection-molded or CNC-machined enclosures where flexibility, insulation, or weight reduction is critical.
For metallic enclosures requiring EMI shielding, corrosion resistance, or structural rigidity, aluminum and steel remain the preferred choices.
Design for manufacturability (DFM) guidelines must be followed to ensure proper bend reliefs, weld accessibility, and cut pattern optimization.

From CAD to Part: The Process

Honyo Prototype Custom Sheet Metal Box Manufacturing Process

Honyo Prototype employs a streamlined, technology-driven workflow for custom sheet metal box production, ensuring rapid turnaround without compromising on manufacturability or quality. The process begins with secure CAD upload via our client portal, supporting industry-standard formats including STEP, IGES, DWG, DXF, and native SOLIDWORKS files. All submissions undergo immediate validation for geometric integrity and unit consistency, with automated alerts for corrupted or incompatible files. Client intellectual property is protected through AES-256 encryption and ISO 27001-compliant cloud infrastructure.

AI-Powered Quoting System
Uploaded CAD data feeds directly into our proprietary AI quoting engine, which analyzes 180+ geometric and material parameters—including bend counts, hole densities, surface area, and alloy specifications—to generate instant, binding quotes within 24 hours. Unlike manual quoting, our system cross-references real-time material costs from vetted suppliers, machine utilization rates, and historical production data to eliminate estimation errors. Clients receive a detailed cost breakdown highlighting material, forming, finishing, and assembly line items, with options to simulate cost impacts of design modifications pre-approval.

Engineering DFM Review
Following quote acceptance, designs enter a dual-phase DFM (Design for Manufacturability) process. First, an automated algorithm checks against Honyo’s 47-point sheet metal rulebook (e.g., minimum flange widths, bend-to-hole spacing, and tool clearance tolerances). Critical violations trigger immediate client alerts with visual markup. Second, a senior manufacturing engineer conducts a manual review focusing on secondary operations, weld accessibility, and finish compatibility. Typical DFM feedback includes specific recommendations such as increasing bend radii to prevent cracking or adjusting tab sizes for robotic welding. This phase averages 48 hours and reduces post-production rework by 63% based on 2023 internal data.

Precision Production Execution
Approved designs move to production using our integrated digital thread system. Laser cutting utilizes 4kW Trumpf systems with ±0.1mm positional accuracy, while Amada press brakes execute CNC-programmed bends with real-time springback compensation. All critical dimensions undergo in-process CMM verification at defined checkpoints. Secondary operations—including MIG/TIG welding per AWS D1.1 standards, powder coating (ISO 9001-certified lines), and hardware insertion—are sequenced to minimize handling. Production timelines are dynamically updated via client portal dashboards, with typical lead times of 5–7 business days for quantities under 50 units.

Quality-Controlled Delivery
Final inspection follows AS9102 First Article Inspection protocols for aerospace-grade boxes or ISO 128-24 for industrial variants, including 3D scan validation against nominal CAD. Boxes are packaged in ESD-safe foam with serialized traceability labels, and shipment documentation includes material certs, FAI reports, and dimensional summaries. Logistics leverage DHL/UPS premium services with GPS tracking, targeting 98% on-time delivery. Clients receive automated notifications at each milestone from dispatch to proof-of-delivery.

Process Timeline and Value Metrics
The table below summarizes phase durations and client benefits:

Process Phase	Typical Duration	Key Value to Client
CAD Upload & Validation	<2 hours	Eliminates format errors upfront; secure IP handling
AI Quote Generation	<24 hours	Transparent cost modeling; no manual quote delays
DFM Review	24–48 hours	Prevents 70%+ of potential production failures
Production	5–7 days	Real-time progress tracking; certified quality
Delivery	1–3 days	Full traceability; on-time delivery guarantee

This end-to-end workflow ensures clients receive manufacturable, high-integrity sheet metal enclosures optimized for cost and speed, backed by Honyo’s 30-year precision fabrication expertise. All processes adhere to ISO 9001:2015 standards with full documentation available upon request.
