Technical Capabilities
Custom Stainless Steel Tube Bending – Technical Specifications Overview
Custom stainless steel tube bending is a precision manufacturing process that integrates advanced CNC tube bending technology with multi-axis milling and turning operations to achieve complex geometries and tight tolerances. While the core process focuses on stainless steel, compatible secondary operations support a range of materials including aluminum, steel, ABS, and nylon for hybrid assemblies or fixturing components. The integration of 3, 4, and 5-axis CNC milling and turning enables secondary feature machining such as porting, drilling, threading, and contouring directly on bent tube assemblies.

| Compatible Materials | Aluminum (6061-T6, 7075), Carbon Steel (1018, 4140), ABS, Nylon (6, 6/6) – for fittings, brackets, or enclosures |
| Tube Diameter Range | 0.25” (6.35 mm) to 2.0” (50.8 mm) OD |
| Wall Thickness Range | 0.028” (0.71 mm) to 0.156” (3.96 mm) – dependent on material and bend radius |
| Bend Radius (CLR) | As low as 1.5x OD (close radius bending with mandrel support) |
| Bending Method | CNC-controlled rotary draw bending, compression bending, or mandrel-assisted |
| Machining Integration | 3-axis, 4-axis (indexed), and 5-axis (continuous) CNC milling and turning |
| Secondary Machining | Drilling, tapping, milling flats, slotting, hole piercing, facing, threading |

| Machining Tolerance | ±0.0005” (0.0127 mm) for critical features; ±0.001” (0.0254 mm) standard |
| Surface Finish (Machined) | 32–125 μin Ra; optional polishing, passivation, or coating (e.g., anodizing, powder coat) |
| Max Part Envelope | 48” x 32” x 24” (1219 x 813 x 610 mm) – varies by machine capacity |
| Quality Control | CMM inspection, laser scanning, first article inspection (FAI), GD&T reporting |

This integrated approach ensures high repeatability, structural integrity, and dimensional accuracy for mission-critical components across industries requiring tight tolerance assemblies with complex 3D geometries.
From CAD to Part: The Process
Honyo Prototype Custom Stainless Steel Tube Bending Process Overview
Honyo Prototype executes custom stainless steel tube bending through a rigorously defined workflow designed for precision, efficiency, and seamless client integration. This process begins with digital file submission and culminates in certified delivery, leveraging proprietary technology and engineering expertise at each phase.
CAD Upload and Validation
Clients initiate the process by uploading native or neutral-format CAD files (STEP, IGES, or Parasolid) via Honyo’s secure client portal. Our system automatically validates geometric integrity, confirming critical parameters including tube diameter, wall thickness, material grade (e.g., 304/316 SS), bend radii, and angular tolerances per ASME B31.3 standards. Incomplete or non-compliant files trigger immediate feedback loops requesting clarification, ensuring downstream accuracy.
AI-Powered Quoting and Feasibility Assessment
Validated CAD data feeds into Honyo’s proprietary AI quoting engine, trained on 15,000+ historical tube bending projects. The engine performs real-time manufacturability analysis, calculating machine setup complexity, cycle times, and material yield while cross-referencing live inventory for stainless steel tube stock. Within 2 business hours, clients receive a detailed quote including cost breakdown, lead time projection, and preliminary bend sequence visualization. Crucially, the AI flags high-risk geometries (e.g., tight bend radii relative to wall thickness causing ovality) for immediate engineering review.
Collaborative DFM Engineering
Quotes involving flagged geometries or client-specified tolerances ≤ ±0.5° enter a mandatory Design for Manufacturability (DFM) phase. Honyo’s senior bending engineers conduct virtual or in-person reviews with the client, proposing optimized solutions such as adjusted bend sequences, mandrel selection, or minor radius modifications to prevent wall thinning or kinking. All DFM iterations are documented in a shared digital work package, with final sign-off required before production release. This phase reduces rework by 73% based on 2023 internal metrics.
Precision Production Execution
Approved designs move to production using CNC-controlled mandrel benders (e.g., Unison B Series) with real-time springback compensation algorithms calibrated for stainless steel’s unique properties. Each tube undergoes in-process verification:
Laser micrometry checks at critical bends for dimensional compliance
CMM validation of complex 3D bend paths against original CAD
Surface integrity inspections to prevent scratching or oxidation
All stainless components receive passivation per ASTM A967 post-bending to enhance corrosion resistance, with material traceability maintained via serialized barcoding.
Certified Delivery and Documentation
Completed orders ship with comprehensive documentation including:
First-article inspection reports (FAIR) with dimensional data
Material test certificates (MTRs) traceable to mill lots
Passivation and cleaning validation records
AS9100-compliant packing lists with protective end-caps for stainless tubes
Shipments are coordinated via client-preferred logistics partners, with real-time tracking and guaranteed on-time delivery adherence per contractual SLAs.
This integrated workflow ensures Honyo delivers custom stainless steel tube assemblies with ≤0.05″ positional accuracy and 99.2% first-pass yield, directly addressing the structural and regulatory demands of aerospace, medical, and semiconductor clients. Technical queries regarding specific alloy behaviors or bend allowances are resolved through Honyo’s dedicated engineering support channel within 4 business hours.
