Modern plastics manufacturing demands high-speed take-out, precise orientation, and fail-safe operation within clamping force windows ranging from 250 Tons to 2300 Tons. Midsize traverse servo robots bridge the crucial operational gap between lightweight 3-axis sprue pickers and heavy-duty 6-axis articulated arms.
By leveraging overhead Cartesian beam structures (traverse setup), these manipulators maintain zero floor-space consumption while optimizing horizontal travel speeds up to 3.0 m/s. Precision servo motor integration across 3 to 5 axes ensures positioning repeatability within ±0.02mm, eliminating part damage and minimizing dry-cycle duration.
Selecting the appropriate drive architecture depends heavily on part complexity, in-mold labeling (IML) needs, and downstream automation integration:
| Model Series | Suitable IMM Clamping Force | Driven Axes | Structure Configuration | Max Payload (kg) | Traverse Stroke (mm) | Positioning Accuracy |
|---|---|---|---|---|---|---|
| WKG-1000 Series | 250T – 450T | 5-Axis AC Servo | Double-Arm Dual-Section | 5.0 – 8.0 kg | 1400 – 1800 mm | ±0.02 mm |
| WKG-1500 Bullhead | 450T – 850T | 3-Axis / 5-Axis Servo | Bullhead Heavy Structure | 10.0 – 15.0 kg | 1800 – 2200 mm | ±0.03 mm |
| WKFI-950 Smart Line | 300T – 600T | 5-Axis Servo | Dual-Arm Telescopic | 7.0 kg | 1600 mm | ±0.02 mm |
| Silicone Special Series | 250T – 400T | 3-Axis Servo | High Rigidity Single Arm | 3.0 – 5.0 kg | 1200 – 1500 mm | ±0.015 mm |
| Heavy Duty 2000T Series | 1500T – 2300T | 3-Axis / 5-Axis Servo | Reinforced Bullhead Traverse | 25.0 – 50.0 kg | 2500 – 3500 mm | ±0.05 mm |

Operating with over 50 dedicated R&D experts and engineers, Zhiyi manufactures up to 2,500 intelligent units annually.
Established with deep insights into Industry 4.0 intelligent manufacturing, focusing on upgrading standard injection factories with automated Cartesian truss systems.
Achieved early dominance in specialized high-speed production sectors, including stainless steel thermos cups, insulated containers, and food container packaging.
Expanded core R&D to multi-axis articulated robots, silicone-molding servo pickers, and automated inline packaging. Secured 13 utility and invention patents covering motion control and mechanical design.
Established localized sales, support, and engineering service centers across Southeast Asia and global industrial hubs, supporting over 25 key global enterprise accounts.
For midsize injection molding operations (450T–850T), standard single-beam structures can exhibit vibration at high arm acceleration. Zhiyi’s proprietary Bullhead (Niutou) traverse frame incorporates high-tensile extruded aluminum profiles backed by dual linear guide rails. This eliminates mechanical deflection during emergency stops and high-speed traverse movements.
Equipped with absolute encoder AC servo motors across all motion axes, Zhiyi robots maintain home position memory even after sudden power shutdowns. Communication via high-speed Bus-control system guarantees microsecond synchronization between vertical stroke extraction and mold opening signals, safeguarding expensive mold cavities.
Featuring a multi-language handheld teaching pendant with intuitive visual touchscreens, operators can sequence custom pick-and-place routines, set multi-point stacking arrangements, and monitor real-time I/O diagnostic signals. Deep learning motion algorithms optimize acceleration curves dynamically based on payload weight.
Midsize molding machines (600T–1300T) producing door panels, instrument clusters, engine covers, and HVAC ducts require high-payload stability. Zhiyi Bullhead traverse robots provide stable extraction of heavy parts up to 15kg, integrating secondary operations like ultrasonic welding, automated trimming, and barcode labeling.
Building on Zhiyi’s foundational expertise, our specialized double-arm servo pickers automate the loading of stainless steel liners and extraction of molded handles or lids. Integrated vision inspection ensures defect-free manufacturing for high-volume consumer goods.
Liquid silicone rubber (LSR) molding demands ultra-clean extraction and minimal tear-off stress. Zhiyi 3-Axis Silicone Servo Robotic Arms offer smooth acceleration profiles, pneumatic gripper control, and ISO Class 7 cleanroom compatibility for syringe barrels, valves, and medical connectors.
For high-cavity fast food boxes, storage containers, and bucket lids (250T–350T IMMs), overall cycle time is critical. Zhiyi dual-section high-speed servo robots achieve in-mold take-out times down to 0.8 seconds, maximizing hourly output and reducing power consumption.
