Custom-engineered industrial automation requires strict mechanical integrity, tight tolerances, and streamlined assembly. This project highlights our full-scope contract manufacturing capability—delivering precision CNC-machined components and complete, functional mechanical sub-assemblies ready for factory-floor integration.
Industry: Industrial Automation & Precision Machinery
Core Capabilities: Multi-axis CNC milling, CNC turning, surface treatment, precision hardware integration, and mechanical bench assembly
Materials: High-grade 6061-T6 / 7075 Aluminum alloy, structural steel fasteners, and custom linkage hardware
Surface Finishing: Matte black anodizing, gold contrast anodizing, and corrosion-resistant hardware coatings
Building multi-component modular assemblies involves challenges beyond simple part machining:
Tolerance Stacking: Assembling structural chassis plates with rotating linkages, cable/spool guides, and structural pedestals meant individual part tolerances had to be held within ±0.01 mm to prevent binding or misalignment across the assembly run.
Surface Quality & Aesthetic Consistency: Combining large-format structural plates with contrasting functional components (gold anodized handles and linkage arms) required uniform surface prep, bead-blasting, and consistent bath control across multiple production lots.
Turnkey Integration: The client required a complete mechanical sub-assembly delivered directly to their production line to minimize their internal assembly lead times and reduce inventory overhead.
| Phase | Execution Details |
|---|---|
| DFM Review | Conducted Design for Manufacturability analysis on tool access, standardized tapped hole patterns, and optimized wall thicknesses to prevent warping during long-bed milling. |
| Multi-Axis CNC Machining | Milled chassis plates, spool wheels, linkage brackets, and mounting discs using high-speed multi-axis machining centers. |
| Surface Treatment | Applied uniform bead-blast finish followed by Type II anodizing (matte black for primary structural bodies, gold for handles and interface points). |
| Mechanical Sub-Assembly | Installed pressed dowels, precision bearings, linkage arms, guide pulleys, and stainless steel fasteners with torque-controlled assembly protocols. |
| Quality Control (QC) | Complete CMM verification for critical dimensions, hole locations, flatness verification, and dynamic clearance testing for rotating linkages. |
100% Turnkey Delivery: Delivered batch units fully assembled and inspected, allowing the client to bolt the modules directly into their master automated system without extra bench work.
Flawless Motion & Fit: Tight GD&T controls eliminated backlash and binding across all articulating links and wheel mechanisms.
Shortened Lead Times: Parallel manufacturing of plate stock and turned hardware alongside in-house assembly reduced overall time-to-market by over 25%.
