Engineered for heavy-duty plastic injection molding, insert loading, high-speed extraction, and tough industrial environment tasks.
In today's rapidly accelerating industrial automation landscape, Zhejiang Zhiyi Intelligent Robot Co., Ltd. has established itself as an authoritative leader and premier OEM/ODM exporter of heavy-duty robotic arms, servo manipulators, and automated end-of-arm tooling systems. Established in 2017, the company aligns its core engineering capabilities with Global Industry 4.0 standards to drive comprehensive digital and mechanical transformation across manufacturing ecosystems worldwide.
Rooted in rigorous mechanical engineering, advanced drive-control integration, and continuous material science innovation, Zhiyi specialized initially in high-precision truss manipulators. Over the years, the organization expanded into high-payload 3-axis and 5-axis bullhead servo robots, 6-axis articulated robot arms, and turnkey packaging automation lines tailored for complex production workflows.
"Our commitment goes beyond assembling robots; we build robust, high-rigidity kinematic platforms capable of maintaining sub-millimeter precision under heavy dynamic loads across continuous 24/7 operating cycles."
Leveraging Zhejiang's world-class robotics manufacturing cluster to provide global enterprises with unmatched lead times, structural reliability, and operational return on investment.
Situated at the heart of China’s advanced machinery hardware corridor, Zhiyi integrates component sourcing—from high-rigidity structural steel castings and precision planetary gearboxes to AC servo motor drivers. This localized integration guarantees rapid prototyping, strict raw material control, and zero supply-chain friction.
By automating labor-intensive extraction, insert placing, and packaging, Zhiyi’s heavy-duty robotic systems help global small-to-medium enterprises (SMEs) and Tier-1 manufacturing plants reduce operating expenses by up to 30%. High speed, continuous duty cycles eliminate bottleneck human errors and scrap rates.
Every robot arm undergoes multi-stage structural analysis (FEA), laser interferometer calibration, and 72-hour continuous burn-in load testing prior to shipment. Fully compliant with CE safety directives and ISO9001 quality management benchmarks, our machines deliver peace of mind for international buyers.

Zhiyi’s proprietary control architecture utilizes real-time Ethernet bus communication protocols to drive absolute encoder AC servo motors. With 11 utility patents and practical inventions covering drive algorithms and hardware design, our robots eliminate mechanical vibration during high-speed take-out operations.
Delivering specialized end-of-arm tooling (EOAT), automated extraction, and downstream packaging systems tailored to distinct manufacturing sectors.
From extraction of massive front/rear bumpers to precision insert placement for electrical connectors. Zhiyi heavy-duty 3-axis bullhead robots handle payloads up to 50kg with micro-metric precision, ensuring scratch-free handling of high-gloss interior components.
Zhiyi’s foundational strength: custom multi-station truss manipulators and articulated arms engineered for stretching, trimming, thermal insulation welding, and automatic boxing of stainless steel thermos cups, lunch boxes, and cookware.
Engineered for high-speed cycle times in ISO Class 7/8 cleanroom environments. Silicone servo-controlled robot arms deliver grease-free vacuum gripping, high-speed take-out, and precise cavity separation for syringe barrels, petri dishes, and blood tubes.
Ultra-fast 5-axis double-arm servo robots integrated with high-precision electro-static label chargers and vision alignment sensors. Achieves sub-second take-out times for thin-wall packaging containers and consumer electronic casings.
Zhiyi actively re-invests a substantial portion of annual revenue into forward-looking R&D. In alignment with global smart factory trends, our technical roadmap focuses on four primary architectural pillars:
Integrating AI edge computing modules directly into servo controllers to enable autonomous obstacle avoidance, dynamic payload mass compensation, and self-tuning motion trajectories.
Deploying vibration, temperature, and current feedback sensors across robot joints to feed cloud telemetry, enabling proactive maintenance alerts before mechanical downtime occurs.
Adopting regenerative braking drives that capture kinetic energy during downward axis deceleration, feeding electricity back to the factory grid to lower overall carbon footprints.
When selecting an OEM heavy-duty robot arm factory, procurement directors and automation engineers evaluate several critical metrics to guarantee minimum Total Cost of Ownership (TCO).
Ensure the robotic arm dynamic payload capacity accounts for EOAT gripper weight, part mass, and acceleration G-forces. Zhiyi engineers conduct comprehensive 3D CAD stress simulations to ensure arm beam rigidity during maximum extension take-out.
Verification of controller communication standards (Euromap 67, Euromap 12, SPI, Ethernet/IP, Profinet) to guarantee seamless handshake signals between the primary machine controller and the robotic arm, avoiding costly field retrofitting.
Every industrial cell presents unique factory ceiling heights, crane clearances, and safety fencing bounds. Zhiyi provides complete OEM dimensional modifications, customizable stroke lengths (traverse, vertical, crosswise), and bespoke gripper design.
