Modern robotics requires materials that mimic the strength of metal but with the agility of advanced polymers. The critical challenges include high torque-to-weight ratios, zero-backlash motion, and seamless sensor integration.

At Jucheng, we don’t just mold; we engineer the structural integrity of the robot. Our ISO 13485 & IATF 16949 certified facility is equipped to handle the extreme requirements of autonomous systems.

Robotics-First Manufacturing

Specialized molding technologies designed for high-frequency motion and extreme durability.

Metal Replacement

Utilizing carbon-filled PEEK and high-flow PA66 to replace heavy aluminum castings, reducing overall robot weight by up to 45% while maintaining structural rigidity.

Sensor Encapsulation

Advanced Insert Molding to encapsulate delicate electronic pins and LIDAR sensors directly into housings, ensuring IP68 waterproof protection for outdoor robots.

Zero-Backlash Gears

Manufacturing ultra-precise transmission components with sub-micron accuracy using our in-house Sinker EDM and 5-axis CNC capabilities.

Specialized Medical Molding

A robot's agility is limited by the precision of its components. Jucheng’s in-house tooling room ensures that every structural joint and gear fits perfectly every time.

25+ 5-Axis CNC Machines: We machine hardened steel molds in-house to achieve parting lines so precise they require zero manual deburring.

Zeiss CMM Metrology: We verify the concentricity of robotic bores and gear tooth profiles to micron levels, ensuring smooth, efficient movement.

Rapid Tooling (10 Days): Our fast-turn mold making allows robotics startups to iterate designs and perform field tests in production-grade resins within weeks.

Robotics Manufacturing FAQ

Yes. By utilizing advanced 5-axis CNC mold making and complex sliding cores, we can create integrated internal pathways for wiring and sensors within a single molded robotic frame.

We use high-wear tool steels (S136 or H13) polished to SPI A-1 standards to ensure the smoothest possible surface finish on gear teeth, reducing friction and extending the life of the component.
