Medium Bull Head 3 Axis Double Stage And Single Arm Injection Robot
Equipment Details
In injection molding production, as product dimensions and weight increase and mold structures grow more complex, light-duty robots suffer from insufficient rigidity and limited load-bearing capacity, failing to sustain long-term stable operation. Targeting core pain points in mass production on medium-tonnage injection molding machines, this robot features purpose-optimized design beyond basic part-removal functions, focusing on equipment stability, mold compatibility and long-duration operational endurance. Supported by precise 3-axis servo control and double-stage single-arm mechanical structure, it achieves high motion accuracy and strong adaptability. After mold opening and part forming, the robot automatically completes full-sequence workflows including mold-entry gripping, mold-exit conveying and positional discharging under fully programmed automatic operation. It supports continuous production of diversified, heavy-weight molded parts and resolves common drawbacks of conventional equipment such as narrow compatibility, unstable running and difficult product change-over.
Product Advantages
Adopting separate main-unit design, the robot delivers intuitive control and easy operation, reliably performing take-out and stacking tasks for 10-30 kg injection-molded parts.
Key transmission components are fitted with high-rigidity precision linear guides and high-strength steel wire belts, paired with optimized servo control system to realize high-speed motion, low-noise performance and millimeter-level positioning accuracy, greatly extending overall service life.
It is also equipped with a 3S full-guide-rail centralized lubrication system for simplified maintenance without complex servicing procedures.
Its core strengths lie in versatility and stability. By swapping grippers or suction cups and adjusting air circuits and programs, it adapts to plastic parts of different geometries. One single machine covers production of multiple product types, perfectly suited for long-hour continuous mass production on medium-tonnage injection molding machines with ample room for further automation upgrades.
Equipment Parameters
Built around 3-axis servo drive and double-stage single-arm configuration, this robot is optimized for medium-load working conditions. Coordinated motion of traverse, vertical and pull-out axes fully automates mold entry, part picking, mold retraction and part discharging. It can be configured for injection molding machines and molds of varied tonnages and sizes, flexibly tuned according to part weight, take-out distance and production cycle, and compatible with diverse end-of-arm tooling. Versus light-duty models, it features upgraded load-bearing structure, motion system and adaptation modules, substantially boosting part-handling capacity, structural rigidity, mold compatibility and product versatility to match diverse operational requirements of medium-scale injection molding.

Applicable Products
It is widely applied to medium-tonnage injection molding for medium-to-large-size, heavy-weight and structurally complex plastic articles, including household plastic wares such as plastic crates, large plastic buckets and storage containers, automotive interior & exterior trims, home-appliance plastic components and assorted industrial plastic parts. Supporting production of differentiated molded products in multiple sizes, it effectively solves automation challenges for removing large-size and heavy-duty plastic parts.
Core Components
All core components are sourced from globally reputable brands, precisely matched according to injection machine tonnage, mold geometry, product parameters and part-removal modes. Premium-grade servo systems, transmission assemblies and control modules combine with high-precision mechanical construction to deliver high overall stability, low failure rate and outstanding wear resistance. Well-suited for high-intensity continuous production, it drastically cuts unplanned downtime and secures production continuity.
Field Application & Customer Feedback
The robot performs excellently in production environments with frequently changing product specifications. Product change-over is fast with minor adjustments to fixtures and programs only, breaking the costly traditional mode of “one dedicated machine for one single product”. One robot handles multiple product lines. It replaces manual labor for strenuous, repetitive part-removal tasks, reducing labor intensity and on-site manpower costs. Operators can focus on machine patrolling, quality inspection, mold change-over, fault handling and production management, lifting overall workshop operational efficiency, and earning wide recognition from injection-molding manufacturers.
Why Choose KOWEY?
Instead of simply scaling up light-duty robot designs, KOWEY addresses key pain points of medium-tonnage injection molding, resolving industry-wide challenges including difficult gripping of large parts, unstable operation for heavy-weight components, poor change-over adaptability and unreliable continuous running. Leveraging proven 3-axis servo drive, double-stage single-arm architecture and modular adaptation design, the robot achieves comprehensive improvements in load capacity, versatility and stability. While light-duty robots focus on “small-size & high-speed” small-part production, KOWEY medium-duty robots excel in “large-coverage general-purpose” manufacturing, covering automated handling for medium-to-large-size multi-category plastic products. It accommodates enterprises’ product iteration and diversified order demands, providing injection-molding factories with high-compatibility, heavy-duty and cost-effective automation upgrade solutions.
