From CAD to Part: The Process
Honyo Prototype Steel Alloys & Services Process Overview
Our end-to-end workflow for steel alloy components integrates advanced digital tools with precision manufacturing rigor, ensuring technical compliance and accelerated time-to-part. The process begins with structured client input and concludes with certified delivery, optimized for complex steel alloys including 4140, 17-4PH, A286, and custom formulations.
CAD Upload & Validation
Clients submit native CAD files (STEP, Parasolid, or native MCAD formats) via our secure portal. Our system performs immediate geometric validation against ASME Y14.5 standards, checking for non-manufacturable features, undercuts, or tolerance conflicts specific to steel’s thermal and machining behavior. Files failing validation trigger automated feedback within 2 business hours, detailing required adjustments to prevent downstream delays.
AI-Powered Quoting with Material Intelligence
Proprietary AI algorithms analyze validated CAD geometry, material specifications, and requested alloys to generate preliminary quotes in under 15 minutes. The system cross-references real-time steel alloy pricing from tier-1 mills, calculates material waste factors for high-value alloys like 15-5PH, and factors in secondary process costs (e.g., stress relieving for 4340). Critical parameters such as hardenability curves and machinability ratings for the selected alloy are embedded in the quote. A senior applications engineer reviews all AI outputs before client delivery to ensure technical feasibility.
DFM Engineering with Alloy-Specific Optimization
Our cross-functional DFM team conducts a 72-hour deep analysis focused on steel-specific challenges. This includes:
Thermal distortion mitigation strategies for heat treatment cycles
Toolpath optimization for abrasive alloys (e.g., tool coatings for 17-4PH H900)
Grain flow alignment recommendations for forged blanks
Residual stress management protocols
We return actionable DFM reports with annotated CAD markups, alternative alloy suggestions (e.g., substituting 303 for 304 in high-machinability scenarios), and cost-impact analysis. Client approval requires formal signoff on all metallurgical recommendations.
Precision Production & In-Process Verification
Manufacturing occurs in our AS9100-certified facility using:
CNC machining centers with rigid tapping and through-spindle coolant for stainless alloys
In-house vacuum heat treatment with quench monitoring per AMS 2750
Coordinate measuring machines running ISO 10360-8 certified inspections
Every steel lot undergoes material traceability via MTRs (Mill Test Reports), with hardness testing at critical stages. Complex geometries receive pre- and post-heat-treatment CMM scans to validate dimensional stability. Secondary services including passivation (ASTM A967), non-destructive testing (MT/PT per ASTM E1417), and precision grinding are sequenced to minimize handling-induced stresses.
Certified Delivery & Technical Documentation
Final shipment includes:
Dimensional inspection reports with GD&T verification
Full material traceability from mill to finished part
Heat treat process documentation (soak time, quench rate, temper curves)
Certificates of Conformance to ASTM/AMS standards
All steel components undergo final visual inspection per ASTM E3022 before packaging in anti-corrosion VCI materials. Typical lead times range from 10–25 days depending on alloy complexity and secondary processes, with real-time logistics tracking via client portal.
