Industrial grade robotic manipulators engineered for high-cycle injection molding extraction, insert loading, and precision automation.
Understanding kinematic synchronization, multi-axis interpolation, and precision extraction in modern smart manufacturing.
In the domain of high-speed industrial plastics manufacturing, precision electronics, and automotive OEM part production, the transition from conventional 3-axis pneumatic/servo hybrid manipulators to fully synchronized 5-Axis AC Servo Robotic Systems represents a paradigm shift in operational efficiency. As global manufacturing environments demand tighter tolerances, reduced cycle times, and dynamic flexible production lines, OEM factory integrators require robotic architectures that deliver sub-millimeter repeat precision combined with dynamic trajectory planning.
A true 5-Axis Servo manipulator system operates across five degrees of freedom: main horizontal traverse axis (X), vertical kick-stroke main/sub arm axes (Y1/Y2), reach transverse movement (Z), and full rotational servo control on the wrist axes (C-axis rotation and A-axis tilting). Unlike pneumatic flip wrist mechanisms that offer only fixed 90-degree indexing with mechanical shock, integrated servo wrists permit infinitely variable angle positioning, soft-touch part extraction from complex mold cavities, and complex trajectory insert placement without interrupting high-tonnage press cycles.
By substituting pneumatic wrist rotations with high-torque absolute AC servo drives, energy consumption is reduced by up to 35% while mechanical vibration is virtually eliminated. Dynamic acceleration curves (up to 12m/s²) enable total part takeout cycles within 0.8 to 1.5 seconds, directly boosting overall equipment effectiveness (OEE) in 24/7 continuous operations.
Equipped with high-resolution absolute encoders on all 5 axes. Eliminates the requirement for manual zero-point homing after power interruptions, reducing startup downtime to zero.
High-speed EtherCAT fieldbus architecture delivers microsecond control loop updates, enabling seamless synchronization between the manipulator, injection molding machine (Euromap 67/73), and downstream automation.
Advanced S-curve acceleration and Jerk-limiting control algorithms minimize structural sway on extended dual-section telescopic arms during high-payload traverse movements.

In-depth technical breakdown of mechanical design, structural kinematics, and OEM/ODM engineering customization.
Zhiyi’s flagship models—such as the WKG-1000 and WKFI-950 series—incorporate high-rigidity extruded aluminum alloy beams and high-strength linear guideways imported from premier global suppliers. The dynamic design features dual-arm, dual-section telescopic vertical structures engineered specifically for low overhead clearance plants. By splitting vertical displacement across two telescopic segments driven by a continuous timing belt loop, maximum vertical stroke is achieved while reducing the overall height footprint by 30-40% compared to single-stage vertical arms.

Trusted by industry leaders across global manufacturing hubs.
Expert insights regarding technical specifications, installation, OEM customization, and global support.
A 3-axis servo robot controls motion along the X (traverse), Y (vertical), and Z (crosswise) axes via servo motors, but uses fixed pneumatic cylinders for wrist flips (0° or 90°). A 5-axis servo robot replaces pneumatics with absolute AC servo drives on the wrist axes (C-rotation and A-tilting). This enables dynamic continuous positioning, micro-angle adjustments, soft part release, complex insert placement, and significantly lower vibration levels.
Zhiyi provides standard Euromap 67 and Euromap 73 electrical interfaces as well as customized hardwired adapter modules for legacy injection press controllers. Our engineering team supplies customized base mounting plates and customized beam extensions to fit presses ranging from 250T to 2,300T regardless of machinery manufacturer.
