Technical Capabilities

Control sheet metal refers to precision-manufactured metal components used in industrial enclosures, control panels, and electrical cabinets. These parts require tight dimensional tolerances and high repeatability, especially for laser cutting, bending, and welding operations. Below are the technical specifications relevant to these manufacturing processes for common materials: Aluminum, Steel, ABS, and Nylon.

Parameter	Aluminum (e.g., 5052, 6061)	Steel (e.g., Mild Steel, SPCC)	ABS (Acrylonitrile Butadiene Styrene)	Nylon (Polyamide)
Laser Cutting
Max Thickness	8 mm	10 mm	5 mm	5 mm
Edge Quality	Smooth, minimal dross	Smooth, slight oxidation possible	Clean cut, slight melting at edges	Melting and burring common
Kerf Width	~0.15–0.25 mm	~0.15–0.25 mm	~0.2–0.3 mm	~0.2–0.3 mm
Recommended Laser Type	Fiber Laser	Fiber Laser	CO2 Laser	CO2 Laser
Bending
Typical Thickness Range	0.8–6 mm	0.5–8 mm	Not recommended for bending	Not recommended for bending
Minimum Bend Radius	1× material thickness (soft tempers)	1× material thickness	N/A	N/A
Springback	Moderate (5–10°)	Low (2–5°)	N/A	N/A
Tooling Requirements	Standard V-dies, wipe bending for tight radii	Standard V-dies, precision tooling	N/A	N/A
Welding
Suitable Processes	TIG, MIG, Laser Welding	MIG, TIG, Spot Welding, Laser Welding	Ultrasonic, Vibration, Hot Plate	Ultrasonic, Hot Plate, Laser
Weld Strength	High (proper filler selection)	High	Moderate to high	Moderate
Heat Sensitivity	Moderate (distortion risk)	Low to moderate	High (melting, warping)	High (absorbs moisture, melts easily)
Joint Preparation	Bevel for thick sections	Square or bevel edge	Chamfered or flush fit	Flush fit, pre-dried if needed
General Notes	Non-magnetic, good corrosion resistance	Magnetic, prone to rust without coating	Thermoplastic, non-conductive, low strength	High wear resistance, hygroscopic

Notes:
Aluminum and Steel are primary materials for control sheet metal fabrication due to structural integrity and EMI shielding.
ABS and Nylon are used selectively for non-structural enclosures or insulating components; they are not suitable for bending or traditional metal welding.
Laser cutting of plastics (ABS, Nylon) requires optimized power and speed settings to minimize melting and fume generation.
Post-processing (deburring, grinding, surface finishing) is typically required for welded and laser-cut metal parts.
Tolerances for laser cutting: ±0.1 mm; bending: ±0.2° angular, ±0.2 mm linear.

From CAD to Part: The Process

Honyo Prototype executes precision sheet metal fabrication through a rigorously defined workflow designed for speed, quality assurance, and client collaboration. The term “control sheet metal” is not standard industry nomenclature; we interpret this as referring to controlled, high-accuracy sheet metal prototyping and low-volume production where dimensional tolerances, material properties, and process validation are strictly managed. Our validated process sequence is as follows.

CAD Upload and Validation
Clients initiate the process by uploading native CAD files (STEP, IPT, SLDPRT) or industry-standard 2D/3D formats via our secure portal. Our system performs immediate format validation, geometry integrity checks, and unit consistency verification. Critical parameters such as material thickness, bend radii, and hole tolerances are auto-extracted. Any ambiguities trigger an instant notification to the client for clarification before proceeding, preventing downstream rework.

AI-Powered Quoting Engine
Validated CAD data feeds into our proprietary AI quoting system, which integrates real-time material pricing, machine utilization rates, and historical production data. The algorithm calculates costs based on geometric complexity, feature density, and secondary operations (e.g., tapping, welding). Crucially, it cross-references our material database to flag non-standard alloys or thicknesses requiring engineering review. Quotes include detailed cost breakdowns and are generated within 2 business hours, with clear notes on any assumptions made.

Engineer-Led DFM Analysis
Every project undergoes mandatory Design for Manufacturability review by ASME-certified sheet metal specialists. This phase is not automated but leverages AI-suggested optimizations as a starting point. Engineers evaluate bend sequences, tooling requirements, and manufacturability risks such as minimum flange lengths or nested part collisions. We provide a formal DFM report with actionable recommendations—like adjusting bend radii to avoid custom tooling—within 24 hours. Client approval of the DFM report is required before production, ensuring alignment on feasibility and cost drivers.

Precision Production Execution
Approved designs move to our climate-controlled fabrication floor. Key controlled processes include:
Laser/punch cutting with ±0.1mm positional accuracy using Bystronic systems
CNC press braking with real-time angle monitoring (repeatability ±0.25°)
In-process inspections at critical stages (e.g., post-bending, pre-welding) via CMM or optical comparators
Material traceability maintained through serialized barcoding from raw stock to finished part
All welding adheres to AWS D1.3 standards, with first-article inspection reports available upon request.

Quality-Controlled Delivery
Final parts undergo comprehensive validation against AS9102 aerospace-first-article standards where applicable, including dimensional reports, surface finish verification, and material certification. We package components with anti-corrosion protection and ship via tracked logistics with real-time status updates. Clients receive a digital quality dossier containing inspection data, process parameters, and non-conformance records if applicable. Standard lead times are maintained through our capacity reservation system.

Process timelines are summarized below for typical 10–50 part batches:

Process Phase	Typical Duration	Key Deliverable
CAD Upload	<1 hour	Validation confirmation
AI Quote	≤2 business hours	Itemized cost breakdown
DFM Analysis	≤24 business hours	Approved DFM report with revisions
Production	5–10 business days	In-process inspection records
Delivery	1–3 business days	Final quality dossier & shipment

This closed-loop methodology ensures that every sheet metal component meets stringent control requirements through embedded engineering oversight, not just automated steps. We maintain ISO 9001:2015 and IATF 16949 certifications, with all critical processes governed by statistical process control (SPC) charts monitored in real time. Client collaboration at the DFM stage remains the cornerstone of preventing quality escapes and achieving first-time-right outcomes.
