Custom Design & Engineering Support

Working from concepts, sketches, or existing designs, our engineering team evaluates CAD drawings for load-bearing requirements, sensor integration feasibility, and motion-control optimization.

Through Design-for-Manufacturing reviews and material selection guidance, we transform robotics concepts into manufacturable, high-performance platforms that balance strength, weight, and cost-effectiveness.

Precision Tube Fabrication & Welding Expertise

Behind every smooth curve and strong weld is a process you can measure. We integrate CNC mandrel bending, laser cutting, and TIG/MIG welding into a seamless production workflow.

CNC Tube Bending

Mandrel bending for load-bearing frames with minimal wall thinning. Typical tolerances ±0.3–0.8 mm depending on diameter and CLR.

Laser Tube Cutting

Precision cutting with mounting holes, cable routes, and sensor pockets prepared in one setup. Tolerances ±0.05–0.1 mm for alignment interfaces.

TIG/MIG Welding

Fixture-controlled welding for dimensional consistency across structural joints. 100% visual inspection with sample NDT available.

Materials & Platform Integration

Material Options

Robotics platforms demand reliable materials and integration strategies. We specialize in aluminum and steel with optimized weight-to-strength ratios and environmental durability.

6061-T6 Aluminum — Lightweight, high strength-to-weight for weight-sensitive AMR
Mild Steel Tube — Cost-effective, excellent rigidity for heavy-duty AGV
HSLA Steel — Superior strength with reduced weight compared to mild steel
Stainless 304/316 — Corrosion resistance for outdoor or washdown environments

Material selection guidance provided during DFM review based on payload capacity, platform size, and environmental conditions.

Platform Integration Features

Motor mount fabrication and alignment
Sensor bracket and cable routing integration
Wheel bearing support and axle integration
Battery pack mounting and thermal management

Every integration point is designed for repeatability and ease of assembly, reducing commissioning time and improving platform reliability.

Integrated Sensor & Component Features

Beyond basic frame structures, we design platforms with built-in features for sensor mounting, power management, and modular expansion.

Sensor Mounting Integration

Built-in fixture points and cable routing channels for LiDAR, camera, and encoder mounting without secondary fabrication.

We act as an extension of your design team, not just a fabricator. DFM feedback within 48h helps optimize designs before production starts.

End-to-End Integration

Tube bending, laser cutting, welding, assembly, and quality inspection under one roof. Fewer handoffs mean faster delivery and consistent quality.

Robotics & Automation Expertise

Proven experience with AMR/AGV platforms, collaborative robots, and automated systems. We understand load requirements, precision needs, and integration constraints.

Frequently Asked Questions

What materials are recommended for mobile robot chassis?

Aluminum 6061-T6 is ideal for weight-sensitive applications (AMR platforms). Steel tube (mild steel or HSLA) is preferred for heavy-duty AGV structures requiring maximum rigidity. Material selection depends on payload capacity, environmental exposure, and weight constraints — guidance provided during DFM review.

Can you integrate motor mounts and sensor attachment points?

Yes. Every chassis is custom-built from your CAD drawings with integrated motor mounting brackets, wheel bearing supports, sensor fixture points, and cable routing channels. Our engineering team validates load paths and alignment during the DFM process.

Do you fabricate complete assemblies or just frame structures?

Both. We can deliver bare frame structures or fully assembled platforms including motor mounts, wheel assemblies, cabling, and sensor brackets. Assembly scope and logistics coordination are discussed during quote phase.

What are typical lead times for AMR/AGV chassis?

From 5–10 business days after design approval, depending on complexity and surface finishing requirements. This includes fabrication, welding, assembly, and final inspection. Expedited timelines available on request for urgent projects.

What quality records can you provide for robotics applications?

We provide First Article Inspection (FAI) reports, in-process inspection logs, dimensional verification records, and Certificates of Conformance (CoC). Material certifications and full traceability available. All records follow ISO 9001 quality management protocols.

Can you work with legacy designs or help optimize existing platforms?

Both. We can fabricate from your complete CAD models or collaboratively develop designs from sketches and concepts. Our engineering team provides DFM feedback to optimize manufacturability, reduce weight, or improve assembly regardless of design maturity.
