High-performance servo manipulators designed for precision plastic injection molding machines, automated extraction, and smart factory optimization.
In the era of smart manufacturing and global supply chain re-alignment, industrial automation has transitioned from a competitive advantage to an operational imperative. Among the key architectural pillars of modern plastic injection molding and automated material extraction, the Vertical-Propelled Robot (commonly known in advanced manufacturing as the top-entry or overhead traverse servo robot arm) stands out as a critical asset for high-speed, high-precision, and continuous multi-shift production environments.
Global procurement metrics show a rapidly rising demand for vertical-propelled robotic arms, propelled by escalating labor costs, stringent safety mandates, and the relentless drive for tighter part-to-part tolerances. Factories across North America, Europe, and Asia-Pacific are modernizing their floor operations by replacing manual demolding and legacy pneumatic pickers with full AC servo vertical-propelled systems. These robots operate above the clamping units of injection molding machines (ranging from 250T to 2300T clamping forces), delivering rapid vertical descent, sub-millimeter part extraction, in-mold label (IML) insertion, and downstream conveyor stacking.
Reduces floor labor requirements by up to 30% while eliminating human fatigue variables in high-heat injection molding environments.
Achieves dry cycle extraction times down to 0.6 seconds, maximizing overall equipment effectiveness (OEE) and plastic throughput.
Integrated vacuum monitoring and optical sensor arrays prevent accidental mold closures on un-extracted workpieces, protecting multi-million dollar molds.
Established in 2017, Zhejiang Zhiyi Intelligent Robot Co., Ltd. has established itself as an authoritative leader in China's industrial automation landscape. As an officially certified National High-Tech Enterprise, Zhiyi integrates cutting-edge robotic R&D, heavy mechanical engineering, precision software control, and international export expertise.
The company’s growth trajectory stems from a deep insight into modern manufacturing challenges. Originating with specialized truss manipulators for thermos cup and stainless-steel lunch box manufacturing, Zhiyi quickly expanded into multi-axis servo vertical-propelled robots, articulated arm robots, and automated downstream packaging machinery.
Adhering to strict international standardizations, all systems manufactured by Zhiyi carry full ISO9001 quality system certification and European CE safety compliance, providing global enterprise clients with absolute peace of mind.
Zhejiang Zhiyi Intelligent Robot Co., Ltd. was established during the crest of the Industry 4.0 evolution. The founders identified a critical market gap: manufacturing plants needed robust, modular, and cost-effective vertical extraction robotics to replace unpredictable manual labor.
Focusing initially on specialized truss manipulators, Zhiyi dominated niche automated extraction lines for thermos cups and metal container manufacturing, setting industry standards for speed and durability.
Zhejiang Zhiyi scaled its portfolio to include 3-axis and 5-axis full servo vertical-propelled robots, articulated multi-joint robots, and intelligent automatic packaging machines across household goods, automotive components, and medical plastic sectors.
Awarded the prestigious title of "National High-Tech Enterprise", Zhiyi aggressively launched its global distribution strategy, building export channels into Southeast Asia, Europe, and the Americas under China's "Belt and Road" trade framework.
Empirical performance metrics driving transformation across global factory floors.
Zhiyi manufactures a complete technological matrix of vertical-propelled and automated robotic systems engineered to handle payloads from light packaging to heavy auto-body components.
Our core product lineup incorporates high-torque AC servo motors on all primary axes (Traverse, Vertical, Cross-wise). Featuring ultra-rigid structural aluminum extrusions and high-precision linear guide rails, these vertical-propelled manipulators guarantee fast acceleration, vibration-free stopping, and dynamic position control for complex part extraction.
For operations requiring multi-degree-of-freedom flexibilities—such as post-mold trimming, ultra-complex insert loading, or 3D trajectory degating—Zhiyi articulated robots deliver industry-leading wrist torque, high repeatability (+/-0.02mm), and versatile mounting options.
Seamlessly integrated at the discharge side of our vertical-propelled extraction robots, Zhiyi automatic packaging equipment executes secondary operations including automated stacking, boxing, bag-sealing, and labeling, forming a 100% lights-out production cell.

Expert answers to common engineering, procurement, and deployment questions regarding vertical-propelled injection molding robots.
Selection depends on three primary variables: your injection molding machine’s clamping force (tonnage), the combined mass of the plastic product and runner system (payload capacity), and the daylight opening height above your machine. For example, machines between 250T and 350T typically use our 3-axis WKG-1500 series, whereas large-tonnage machines (2000T-2300T) require our heavy-duty dual-arm, multi-axis servo systems.
A 3-axis servo robot controls motion along the X (traverse), Y (vertical), and Z (cross-wise) cartesian axes. It is ideal for standard part extraction, runner separation, and simple conveyor placement. A 5-axis servo robot adds full servo rotation to the wrist/end-of-arm tooling (C-axis and A-axis), allowing complex part manipulation, precise insertion into angled mold cavities, or intricate post-extraction orientation for secondary processing.
