Why teams choose us

Prototype parts that are ready for real testing

Robotics components must do more than look correct. They need to fit, move, align, and survive functional testing. Our engineering workflow focuses on the parameters that affect your build.

01

Tight tolerance fits

Bearing seats, precision bores, and shaft fits are machined to ±0.01 mm, or ±0.005 mm where specified.

02

Practical DFM feedback

Our engineers review thin walls, deep cavities, and inaccessible features before machining and suggest actionable improvements.

03

Materials on hand

Common choices include 6061-T6 and 7075-T6 aluminum, 303/304 stainless steel, POM, and PEEK.

04

Ready-to-assemble delivery

Coordinate anodizing, bead blasting, heat treatment, and laser marking so parts arrive ready for the assembly bench.

Technical capability

CNC machining for complex robotics geometry

Our Shenzhen facility supports multi-axis machining for robot arm links, actuator housings, and other complex components. Fewer setups help improve accuracy while reducing lead times.

Minimum quantity 1 piece
Standard tolerance ±0.01 mm
Tight tolerance Down to ±0.005 mm
Surface roughness Ra 0.4–3.2 μm
Prototype lead time 3–7 working days
File formats STEP, STP, IGES, X_T, DWG, DXF, PDF

Applications

Common robotics components we prototype

High structural integrity and precise alignment for robotic systems, automation equipment, and mobile platforms.

Joint and actuator housings

Complex internal geometry for motors, gearboxes, and encoders.

End-effector and EOAT

Custom gripper fingers, tool changer adapters, and mounting plates.

Structural components

Robot arm segments, base plates, and chassis parts.

Motion control

Precision shafts, motor mounts, and wheel hubs for AGVs and AMRs.

Sensor integration

Custom brackets and housings for LiDAR, cameras, and proximity sensors.

Built for continuity

From prototype to low-volume production

Once your prototype passes functional testing, move into pilot runs without restarting the manufacturing process. We maintain project data and optimized machining programs to support quantities of 50, 100, or 500 units.

1

CAD review

Review manufacturability, critical features, materials, and finishing requirements.

2

Functional prototype

Validate fit, motion, alignment, and assembly with production-relevant parts.

3

Pilot production

Optimize fixtures and tool paths for repeatability and consistent batch performance.

Quality assurance

Inspection focused on fit and function

For robotics, a part that does not fit is a failed part. We use CMM equipment, optical measuring tools, and precision gauges to verify the features that influence your motion system.

GD&T

True position, flatness, parallelism, and concentricity.

Critical fits

Clearance and interference requirements for bearings and shafts.

Documentation

FAI reports, dimensional reports, and material certifications as needed.
