Honyo Prototype supports rapid prototyping and low-to-mid volume production runs, with integrated design for manufacturability (DFM) feedback and secondary services including anodizing, plating, painting, and heat treatment.
From CAD to Part: The Process
Honyo Prototype executes a streamlined, technology-driven workflow for steel alloy component manufacturing and related services. The process begins when a client uploads a CAD file to our secure platform. This initiates our integrated system designed for precision engineering and rapid turnaround in the steel fabrication sector.
Upload CAD
Clients submit 3D models in standard formats including STEP IGES and Parasolid. The platform automatically validates file integrity and geometry completeness specific to steel alloy processing requirements. Critical parameters such as material specifications surface finish requests and tolerance classes are captured during this ingestion phase. For steel alloys this includes explicit declaration of required grades such as 4140 17-4PH or 316L along with any secondary operation needs like heat treatment or plating.
AI Quote Generation
Our proprietary AI engine analyzes the CAD geometry against real-time data from our manufacturing network. The system evaluates steel-specific factors including raw material costs machining complexity and thermal processing requirements. Within minutes the client receives a comprehensive quote detailing itemized costs lead time and material certification options. Key variables driving the quotation are summarized below.
| Parameter | Steel Alloy Consideration | Impact on Quote |
|---|---|---|
| Material Grade | 4140 vs 15-5PH cost differential | Raw material cost multiplier |
| Tolerance Class | ISO 2768-mK vs tighter geometric tolerances | Machining time adjustment |
| Secondary Operations | Heat treatment plating or stress relieving | Process chain duration |
| Annual Volume Commitment | Tiered pricing for recurring orders | Unit cost reduction |
Design for Manufacturing DFM Analysis
Honyo’s engineering team conducts a rigorous DFM review focused on steel alloy manufacturability. This phase identifies potential issues such as inadequate draft angles for cast steel insufficient wall thickness for machined parts or non-optimal grain flow orientation. Our engineers collaborate directly with clients to suggest modifications that maintain functional requirements while reducing cost and lead time. Typical steel-specific recommendations include adjusting fillet radii to prevent stress concentrations modifying features to minimize deep cavity machining or selecting alternative alloys with better machinability.
Production Execution
Approved designs move to our partnered network of ISO 9001-certified steel fabrication facilities. Production encompasses precision CNC machining turning milling and grinding alongside specialized steel processes including vacuum heat treatment shot peening and non-destructive testing. Every steel lot undergoes material traceability verification with full mill test reports provided. In-process inspections using CMM and optical comparators ensure adherence to specified tolerances with real-time data fed back to our production dashboard.
Delivery and Documentation
Finished components undergo final QA including dimensional verification and surface finish checks per client specifications. Steel parts are packaged with anti-corrosion protection appropriate for the alloy type and shipped via client-preferred logistics channels. Comprehensive documentation accompanies each delivery including first article inspection reports material certifications heat treat records and dimensional reports. Honyo maintains a digital twin of every order enabling full traceability from raw material to end delivery with post-delivery technical support available for assembly or integration queries.
