Technical Capabilities
Technical specifications for custom metal parts manufactured in China typically involve precision processes such as laser cutting, bending, and welding. These processes are primarily applied to metal materials like aluminum and steel. While ABS and nylon are not metals and therefore not suitable for laser cutting and welding in the same context as metals, they are included here for comparison in hybrid or multi-material fabrication environments.
Below is a summary of the technical capabilities and material compatibility for each process:
| Process | Material Compatibility | Thickness Range | Tolerance | Equipment Type | Notes |
|---|---|---|---|---|---|
| Laser Cutting | Aluminum, Steel | 0.5 mm – 25 mm | ±0.1 mm – ±0.2 mm | Fiber Laser / CO₂ Laser | High precision; clean edges; not suitable for ABS/nylon due to melting and fume hazards |
| Bending | Aluminum, Steel | 0.8 mm – 12 mm | ±0.2° angular, ±0.1 mm linear | CNC Press Brake | Limited by material ductility; tooling varies by bend radius and angle; ABS/nylon not typically bent using industrial press brakes |
| Welding | Aluminum, Steel | 1 mm – 20 mm | ±0.5 mm positional | MIG, TIG, Spot Welding | Full fusion joints; requires skilled operation; ABS and nylon may be joined via ultrasonic or adhesive methods but not arc welding |
| Alternative Processing (for ABS/Nylon) | ABS, Nylon | 1 mm – 10 mm | ±0.1 mm | CNC Machining, 3D Printing | Used for non-metal components; laser cutting possible with ventilation but not recommended for structural welding applications |
Additional Notes:
Laser cutting is highly effective for aluminum and steel due to precise control and minimal heat-affected zones when optimized. Bending operations rely on material formability, with aluminum alloys (e.g., 5052, 6061) and mild steel (e.g., Q235, SPCC) being most common. Welding requires proper shielding gas and parameter settings—TIG for aluminum, MIG for steel—to ensure strong, clean joints.
ABS and nylon are thermoplastics and are generally processed using non-metal fabrication methods such as CNC machining, injection molding, or 3D printing. While CO₂ lasers can cut these plastics, they are not compatible with welding techniques used for metals and require alternative joining methods like solvent bonding, ultrasonic welding, or mechanical fastening.
For hybrid assemblies, metal and plastic components are often fabricated separately and integrated during assembly.
From CAD to Part: The Process
Honyo Prototype Custom Metal Parts Manufacturing Process
Honyo Prototype executes a streamlined, technology-driven workflow for custom metal parts production, ensuring precision, speed, and cost efficiency from initial design to final delivery. The process begins with secure CAD file submission through our encrypted client portal, supporting industry-standard formats including STEP, IGES, and native SolidWorks files. Upon upload, our proprietary AI quoting engine analyzes geometric complexity, material requirements, tolerances, and surface finish specifications to generate an instant preliminary quote within minutes. This AI system cross-references real-time data on raw material costs, machine utilization rates, and labor variables specific to metal fabrication, eliminating manual estimation delays while maintaining technical accuracy for alloys such as aluminum 6061, stainless steel 304/316, and titanium Ti-6Al-4V.
Following client acceptance of the AI-generated quote, the project enters Design for Manufacturability (DFM) review. Honyo’s engineering team conducts a rigorous technical assessment focused on metal-specific constraints, including but not limited to: minimizing secondary operations, optimizing tool path efficiency, addressing thermal distortion risks in welding, and ensuring feature feasibility for CNC milling or turning. Critical DFM considerations for metal parts are systematically evaluated as shown below.
| DFM Parameter | Metal-Specific Focus Areas | Typical Resolution Time |
|---|---|---|
| Wall Thickness | Avoidance of thin-wall deformation during machining | <24 hours |
| Tolerance Stack-Ups | Compensation for thermal expansion in multi-axis setups | <24 hours |
| Undercut Features | Feasibility assessment for 5-axis vs. wire EDM solutions | <48 hours |
| Material Utilization | Nesting optimization to reduce scrap in sheet metal fabrications | <24 hours |
Client collaboration is integral during DFM; engineers provide actionable recommendations via annotated 3D models or formal reports, with 95% of revisions resolved within 72 hours. Upon DFM sign-off, production commences in our Shenzhen facility using certified ISO 9001:2015 processes. Metal parts undergo precision machining via HAAS CNC mills, DMG MORI lathes, and AMADA laser cutters, with in-process inspections at critical stages using Zeiss CMMs and optical comparators. All components adhere to specified ASTM or ISO material certifications, with full traceability maintained through serialized batch records.
Final quality validation includes first-article inspection reports (FAIR) per AS9102 standards for aerospace clients or PPAP Level 3 documentation for automotive sectors, accompanied by material test certificates. Parts are packaged in anti-corrosion VCI film with custom foam cradling for transit security. Delivery leverages DHL/FedEx priority logistics with real-time shipment tracking, typically achieving 10–15 business day turnaround from CAD approval to doorstep delivery for standard orders. Honyo’s integrated workflow reduces traditional metal prototyping lead times by 40% while maintaining ±0.005mm dimensional accuracy, ensuring clients receive production-ready components without iterative redesign cycles.
