Fabrication Equipment and Tolerances

Precision robotics require repeatable execution, not guesswork. Below are the exact hardware specs and tolerances ShincoFab utilizes to bring your CAD files from prototype to production.

High-Speed Fiber Laser Cutting

  • The Equipment: Trumpf & Amada 10kW+ fiber lasers.
  • The Specs: Utilizing advanced sheet metal cutting techniques, we perform laser cutting on robotic components up to 20mm (Steel) and 10mm (Aluminum/Stainless) with clean, dross-free edges. Minimal Heat-Affected Zone (HAZ) to prevent material warping on thin-gauge sensor housings.
Multi-axis CNC press brake for precision bending

Multi-Axis CNC Bending & Forming

  • The Equipment: Multi-axis CNC press brakes with 6-axis precision backgauges.
  • The Specs: Our precise sheet metal forming and bending for robotics maintains angle tolerances strictly to +/- 0.5° and dimensional tolerances to +/- 0.1mm. Ensuring absolute repeatable alignment for complex, multi-part robotics frames, eliminating fit-up issues during final assembly.

Structural & Cosmetic Welding

  • The Equipment: TIG, MIG, and robotic spot welding stations.
  • The Specs: Executed by AWS-certified welders providing robust robotic welding and assembly services. Achieving deep penetration for chassis structural integrity under high dynamic/torsional automation loads. Clean, spatter-free TIG welds for visible external enclosures.

Precision Hardware Insertion

  • The Equipment: Automated Haeger hardware insertion machines.
  • The Specs: In-house insertion of PEM nuts, studs, and flush-head standoffs. Strictly depth-calibrated to guarantee instantaneous, thread-perfect mounting for PCBs, servos, and lithium battery packs.

Engineered Materials for Robotics

In robotics, over-engineering adds dead weight, and under-engineering risks catastrophic failure. We stock and process raw materials specifically chosen for kinetic mobility and static structural demands.

High-grade 5052 and 6061 aluminum alloy sheet metal

Aluminum Alloys: 5052-H32 & 6061-T6

  • Optimal Robotics Use: End-of-arm tooling, AGV external covers, and low-inertia brackets.
  • Material Advantage: We use 5052-H32 for complex enclosures because its superior formability allows for tight structural bends without cracking. We utilize 6061-T6 for rigid mounting plates where high yield strength and machinability are critical to keeping payloads light.
Precision 316L stainless steel components for medical robotics

Stainless Steel: 304 & 316L

  • Optimal Robotics Use: Medical/Surgical robots, food-handling automation, and washdown environments.
  • Performance Advantage: Standard 304 offers robust overall corrosion resistance for lab automation. For harsh environments (repeated chemical washdowns), we utilize 316L; the lower carbon content prevents weld-decay and chloride pitting, ensuring your IP ratings hold true.
Heavy-duty welded steel chassis for high-payload AMRs

Cold Rolled Steel (CRS) & Galvanized

  • Optimal Robotics Use: High-payload AMR base frames, static industrial control cabinets, and heavy counterweights.
  • Structural Advantage: When supreme structural rigidity vs. cost is the primary metric, CRS delivers. Welded into torsion-resistant box frames and finished with tight in-house powder coating, it handles massive dynamic shifts in center-of-gravity (CoG) without failing.

From Prototype to Volume Production

Hardware development is gated by prototype speed. Hardware profitability is gated by manufacturing scalability. We built a continuous workflow that seamlessly handles both, offering complete robotic sheet metal prototyping and production solutions.

Phase 1: Rapid Prototyping & Iteration

  • 1 to 5 Day Turnaround: As experts in rapid prototyping for robotic sheet metal components, we help you validate your robotic assemblies faster. Because we keep sheet metal cutting, bending, and welding strictly in-house, we eliminate outsourcing delays.
  • Strictly ZERO MOQ : R&D requires trial and error. Whether you need a single proof-of-concept chassis or a 5-piece beta run, we process it with the same engineering rigor as a volume order.

Phase 2: Volume Production & Contract Manufacturing

  • Seamless Translation to Scale: Never lose your tribal knowledge. The same CAM programs, tooling setups, and FAIs (First Article Inspections) used for your prototype are instantly optimized for medium to high-volume runs.
  • Predictable Landed Costs: When it is time to scale robotic sheet metal production, we implement dedicated fixturing and robotic welding to drive your per-unit costs down, delivering strictly on budget and on your exact MRP schedule.

DFM Engineering and CMM Inspection

CAD software allows you to draw physical impossibilities. We ensure they actually work in the real world. Our process is designed to protect your project timeline and guarantee a frictionless fit during final assembly.

Optimized sheet metal nesting for maximum material yield

Proactive DFM Reviews

Before our lasers ever pierce a sheet of metal, our in-house manufacturing engineers optimize design for manufacturability (DFM), running a ruthless diagnostic on your STEP/IGES files. We don’t just blindly cut what you send. We optimize it to prevent costly failures:

  • Bend Radius & K-Factor Checks: Identifying impossibly tight radii that will cause aluminum to crack or tear during CNC forming, saving you from receiving compromised brackets.
  • Warping & Weld-Distortion Prevention: We evaluate thin-gauge layouts to ensure they won’t warp under laser heat or heavy TIG welding, guaranteeing your enclosures remain perfectly flat.
  • Nesting Inefficiencies: We digitally nest your flat patterns to maximize material yield. Less wasted material equals a lower per-part cost on your invoice.

CMM Inspection and Material Traceability

Quality isn’t an adjective here. It is a documented metric. We strictly inspect and control quality for robotics fabrication, providing the hard paperwork your supply chain and QA departments demand.

  • 100% CMM Verified FAI. We measure your initial prototypes using advanced Coordinate Measuring Machines. You receive a comprehensive First Article Inspection report detailing exact dimensional compliance before we initiate volume production.
  • Full Material Traceability. Essential for medical and high-stakes robotics. Every shipment can be accompanied by Mill Test Reports (MTRs), proving the exact chemical composition of the steel or aluminum housing your IP.

Assembly-Ready Surface Finishing

A robotic chassis isn’t finished until it’s shielded against its operating environment. We provide comprehensive robotic sheet metal part surface finishing options, managing the final coatings and enforcing strict hardware masking protocols to ensure your parts arrive functional and flawlessly finished under a single PO.

Anodizing (Type II & Type III Hardcoat)

  • Application: Aluminum robotic arms, sensor mounts, and kinetic joints.
  • Engineering Rationale: Type II provides essential corrosion resistance, while Type III Hardcoat drastically increases surface hardness. This minimizes friction and wear on continuously moving aluminum assemblies, ensuring longer service life for your final product.

Industrial Powder Coating & Masking

  • Application: Heavy-duty AGV/AMR chassis, outer skins, and control cabinets.
  • Engineering Rationale: A high-durability, baked-on finish engineered to survive industrial impacts and chemical spills. Crucially, we utilize dedicated silicone plugging and masking techniques to ensure PEM threads and precision mounting holes remain completely free of overspray. It arrives ready to bolt.

Passivation (ASTM A967 Standards)

  • Application: Medical, surgical, and food-handling robotics (304/316 Stainless).
  • Engineering Rationale: Machining and welding leave behind microscopic “free iron” particles on the surface, which will eventually rust. Chemical passivation removes these contaminants and accelerates the formation of a pure chromium-oxide protective layer, securing your strict cleanroom compliance.
