Engineered for high-tonnage injection molding automation, precision extraction, and automated downstream processing.
A comprehensive engineering guide to selecting high-precision 3-axis and 5-axis servo manipulators for modern smart factories.
Modern plastics manufacturing demands absolute precision, minimized dry cycle times, and zero-defect quality control. As global OEMs transition toward Industry 4.0 architecture, the integration of high-performance servo robotic arms has evolved from an operational option to a baseline necessity. Industrial automation in injection molding presses ranging from 250T to 2300T requires structural rigidity, high dynamic response, and seamless communication between the injection press controller and the robotic manipulator.
At Zhejiang Zhiyi Intelligent Robot Co., Ltd., we engineer tailored robotic systems designed to eliminate bottleneck operations during component extraction, insert molding, in-mold labeling (IML), and automated degating. By adopting high-torque AC servo drives across all linear and rotational axes, our machines deliver positional repeatability down to ±0.02mm, maintaining operational stability across 24/7 continuous production cycles.
Selecting the optimal robot architecture depends heavily on part complexity, mold layout, and post-processing requirements. Our engineering portfolio spans two primary mechanical topologies:
The table below summarizes standard baseline parameters across our OEM manufacturing lines. Custom payload capacities, stroke lengths, and drive configurations are tailored per factory specification.

| WKG-1500 Bullhead | 400T - 800T | 3-Axis Bull Head Heavy Duty | 15.0 kg / 20.0 kg | 1.5 - 2.2 s | ±0.04 mm | Automotive interior panels, home appliance housings, crates |
| WKG-2000 Ultra-Large | 2000T - 2300T | 3-Axis / 5-Axis Double Arm | 30.0 kg / 50.0 kg | 2.5 - 3.8 s | ±0.05 mm | Automotive bumpers, logistics pallets, large agricultural tanks |
| Silicone Special Series | 250T - 400T (LSR) | 3-Axis Dedicated Servo | 3.0 kg / 5.0 kg | 0.6 - 1.0 s | ±0.01 mm | Liquid silicone rubber seals, baby products, medical devices |
Proven quantitative results backed by rigorous manufacturing quality, extensive patent portfolios, and worldwide client deployment.
Capitalizing on Zhejiang's world-class robotics hardware cluster to provide high-efficiency, cost-effective automation.
Operating in Zhejiang's advanced industrial hub allows Zhejiang Zhiyi to integrate world-class sub-tier suppliers. We source premium-grade linear guide rails, low-backlash planetary gearboxes, and Japanese/European AC servo motors directly. Coupled with in-house CNC machining of structural aluminum beams and steel weldments, our supply chain guarantees exceptional mechanical integrity and short turnaround times.
Every manufacturing plant exhibits unique ceiling heights, mold dimensions, and downstream handling needs. Our technical team works alongside global buyers to engineer custom End-of-Arm Tooling (EOAT), tailored stroke extensions, specialized dual-arm configurations, and modified mounting adapter plates for seamless retrofitting onto existing injection molding presses.
Through streamlined assembly processes, standardized modular structural components, and high volume production scaling, Zhejiang Zhiyi offers a market-leading price-to-performance dynamic. Capital investments in our robotic systems generally achieve full payback within 8 to 14 months through labor savings, cycle optimization, and reduced scrap rates.
Ensuring operational reliability, regulatory compliance, and seamless multi-national deployment.
Safety and regulatory compliance are paramount for tier-1 automotive and global medical device manufacturers. All Zhejiang Zhiyi robotic arms are manufactured under ISO9001:2015 Quality Management Systems and hold formal CE Certification in accordance with EU Machinery Directive 2006/42/EC and EN ISO 10218-1 industrial robot safety standards.

Clear answers to critical technical questions asked by global procurement teams and automation engineers.
A 3-axis servo robot is suitable for standard, fast-cycle extraction operations where the molded part is extracted vertically and dropped or stacked onto a conveyor. A 5-axis servo robot adds rotational axes (wrist movements), making it necessary for complex mold geometries with under-cuts, insert molding (placing metal parts into the mold), in-mold labeling (IML), or when high-precision part orientation is required downstream.
Zhiyi robots support standardized international communication interfaces including EUROMAP 12, EUROMAP 67, and SPI interfaces. This ensures plug-and-play safety interlock signals (mold open, mold closed, ejector enable, safety gate) across major molding machine brands worldwide (e.g., Haitian, Engel, KraussMaffei, Sumitomo, Yizumi).
Standard 3-axis and 5-axis robot configurations are produced and shipped within 2 to 3 weeks. Custom OEM designs—such as specialized high-load beam modifications, extended vertical strokes for deep-cavity molds, or customized pneumatic/vacuum End-of-Arm Tooling—typically require 4 to 6 weeks from initial design approval.
Quality assurance includes strict 100% component inspection (ISO9001:2015), laser tracker dynamic calibration, and a mandatory 72-hour continuous dynamic burn-in test at maximum payload before factory clearance. Additionally, key structural components utilize stress-relieved high-strength alloy extrusions.
Yes. Our heavy-duty Bullhead and dual-arm heavy-load series (e.g., WKG-2000 and WKG-1500) are engineered specifically for press tonnages from 1000T up to 2300T, handling total payloads up to 50 kg with dual-section vertical arms for low overhead clearance rooms.
