Technical Capabilities

Honyo Prototype provides precision metal fabrication services in China with advanced capabilities in laser cutting, bending, and welding. Our processes are optimized for high accuracy, repeatability, and structural integrity across a range of materials including aluminum, steel, and select engineering plastics such as ABS and nylon for compatible secondary operations. Below are the technical specifications for each core fabrication process.

Process	Material Compatibility	Thickness Range	Tolerance	Equipment Type	Notes
Laser Cutting	Aluminum, Steel, Stainless Steel	0.5 mm – 25 mm	±0.1 mm	Fiber Laser Cutting Machines (up to 6 kW)	Nitrogen or oxygen assist; kerf compensation applied; not recommended for ABS or nylon due to thermal deformation
Bending	Aluminum, Steel, Stainless Steel	0.8 mm – 12 mm	±0.2° angular, ±0.5 mm linear	CNC Press Brakes (up to 200 tons)	Standard V-die tooling; minimum flange 3× material thickness; not applicable for ABS or nylon
MIG/TIG Welding	Aluminum, Steel, Stainless Steel	1.0 mm – 20 mm	±1.0 mm alignment	Pulsed MIG, DC TIG with Argon shield	Full penetration welds; post-weld grinding/filing available; certified welders (ISO 9606)
Spot Welding	Steel, Stainless Steel	0.5 mm – 3 mm (per sheet)	±0.5 mm electrode placement	Servo-driven Spot Welders	Up to 10 kA capacity; not suitable for aluminum or plastics
Secondary Handling	ABS, Nylon (limited)	Machined or bonded only	±0.1 mm (machined)	CNC Milling, Adhesive Bonding	ABS and nylon are non-weldable and non-bendable; processed separately and integrated via fastening or bonding

Notes on Material Use:
Aluminum: Grade 5052, 6061-T6 commonly used; excellent weldability with TIG; reflective properties managed via high-brightness fiber lasers.
Steel: Mild steel (Q235, Q345) and stainless steel (304, 316) supported; laser-cut with minimal dross using oxygen assist for thick sections.
ABS & Nylon: Not processed via laser cutting (risk of melting), bending, or welding. Used only for hybrid assemblies where mechanical fastening or adhesive bonding is employed.

All fabrication workflows follow ISO 9001 quality standards with in-process inspection and first-article reporting available upon request.

From CAD to Part: The Process

Honyo Prototype Metal Fabrication Process: China Operations

Honyo Prototype executes a streamlined, technology-driven metal fabrication workflow for clients requiring precision components manufactured in China. This integrated process ensures technical accuracy, cost efficiency, and supply chain transparency from initial design to final delivery. The sequence begins with secure digital submission of client CAD files through our proprietary online portal. This platform validates file formats (STEP, IGES, native CAD), confirms geometric integrity, and automatically assigns a unique project ID for traceability. All data transmission adheres to ISO 27001 standards, ensuring intellectual property protection throughout the engagement.

AI-Powered Quoting System
Upon CAD validation, our machine learning engine initiates the quotation phase. This system analyzes over 200 geometric and material parameters—including sheet thickness, bend counts, tolerance stacks, surface finish requirements, and alloy specifications—against real-time data from our certified Chinese manufacturing partners. The algorithm factors in current raw material pricing (e.g., SS304, 6061-T6), machine hourly rates, secondary operation costs, and logistics variables to generate a technically validated quote within 2 business hours. Crucially, the AI flags potential manufacturability risks at this stage, such as non-standard tooling requirements or ambiguous GD&T callouts, providing immediate feedback before formal commitment.

Engineering-Driven DFM Analysis
Following quote acceptance, our China-based engineering team conducts a rigorous Design for Manufacturability review. This phase leverages both automated simulation and human expertise to optimize the design for Chinese production realities. Key focus areas include:

Potential Issue Category	Resolution Protocol	Chinese Facility Impact
Tight tolerances on complex bends	Propose geometric simplifications or alternative tooling	Avoids costly CNC press brake recalibration delays
Non-standard hole patterns	Recommend ISO metric fastener compatibility	Ensures access to local tooling inventory
Unspecified weld prep	Define groove geometry per AWS D1.1	Prevents rework at Shenzhen welding stations
Surface finish conflicts	Substitute equivalent Chinese GB standards	Maintains quality while using local resources

This DFM stage typically reduces production lead times by 15-25% through preemptive issue resolution and generates formal documentation including revised flat patterns, bend sequences, and process-specific tolerance maps approved by the client.

Certified Production Execution
Approved designs move to Honyo-vetted facilities in Dongguan and Ningbo, all holding ISO 9001, IATF 16949, and NADCAP accreditations. Production utilizes Japanese Amada laser cutters (±0.1mm accuracy), TruBend 7000 series press brakes, and robotic welding cells. Each batch undergoes in-process verification at three critical control points: post-cutting dimensional checks via CMM, mid-bend angle validation, and final assembly first-article inspection. Material certifications (MTRs) and process validation records are digitally logged in our cloud-based quality management system, accessible to clients via secure dashboard.

Global-Ready Delivery Logistics
Completed components undergo final packaging per international shipping standards—vapor-corrosion inhibitors for marine transport, ESD-safe materials for electronics clients, and custom crating for oversized assemblies. Honyo manages all export documentation including Chinese customs declarations, FDA 2877 forms for medical devices, and HS code classification. Shipments consolidate through our Shenzhen bonded warehouse with options for DDP (Delivered Duty Paid) terms to North America, EU, or APAC destinations. Real-time tracking integrates with client ERP systems, providing end-to-end visibility from factory gate to receiving dock with guaranteed on-time delivery performance exceeding 98.5%.
