ALFA ROBOT REDSTONE SERIES 50T-800T INJECTION MOLDING ROBOT ARM
Full Servo Traverse Beam Robot Systems
The Alfa Robot Redstone Series is a full servo-driven traverse beam robot arm series specifically developed for plastic injection molding machines ranging from 50 tons to 800 tons. Combining high precision, short cycle times, and industrial-grade durability, the Redstone series is positioned as a core automation component for modern injection molding production facilities.
Redstone series robots significantly improve production efficiency by delivering high speed and repeatability in operations such as part removal, sprue separation, product stacking, transfer, and integration with secondary processes. Thanks to their full servo structure, they offer a much more stable, quiet, and energy-efficient operation compared to pneumatic systems.
GENERAL TECHNICAL STRUCTURE AND DESIGN
Redstone series robots feature a high-rigidity main body and traverse beam constructed from aluminum alloy. This structure ensures minimal vibration and maximum positioning accuracy even at high operating speeds. Precision linear guides and rail systems used on all axes are designed to minimize wear and maintain long-term accuracy during continuous industrial operation.
The standard robot configuration is available with 3-axis servo control, while an optional 5-axis servo motor configuration is offered for more complex applications. All axes are driven by AC servo motors, and movements are controlled via a fully closed-loop control system.
Servo motor system features include:
- High acceleration and deceleration capability
- ±0.1 mm repeatability
- Low vibration and high positioning accuracy
- Long service life with low maintenance requirements
COMPATIBLE INJECTION MOLDING MACHINE RANGE
Redstone Series robots are available in multiple models designed to match injection molding machines from 50T to 800T. This wide tonnage compatibility allows the same automation platform to be used in both small, high-precision part production and large technical component manufacturing.
Compatible machine tonnage range:
- Minimum: 50 tons
- Maximum: 800 tons
PAYLOAD AND LOAD CAPACITY
Depending on the application and robot configuration, Redstone series robot arms offer payload capacities ranging from 3 kg to 10 kg. Payload values are optimized according to reach distance and arm structure.
Maximum payload capacity:
- Standard configuration: 3 - 10 kg
These values include EOAT (End of Arm Tooling), vacuum systems, and auxiliary components.
AXIS STROKES AND MOTION RANGES
To adapt to various injection molding machine sizes, Redstone series robots provide a wide range of axis stroke options.
Typical axis stroke values:
- Traverse (X-axis): 800 - 1600 mm
- Vertical (Z-axis): 700 - 1100 mm
- Cross / extraction (Y-axis): 150 - 250 mm
This stroke flexibility enables safe and fast part removal even from deep molds and machines with large mold opening distances.
SPEED AND CYCLE PERFORMANCE
One of the key advantages of the full servo drive system is high speed combined with reduced cycle time. The Redstone series is particularly effective in high-volume mass production environments.
Typical performance values:
- Minimum single cycle time: 1.2 seconds
- Dry cycle time: approximately 4.7 seconds
Actual cycle times may vary depending on payload, stroke length, and programmed motion profiles.
CONTROL SYSTEM AND OPERATOR INTERFACE
Redstone series robots are equipped with a user-friendly industrial control system. A large touchscreen HMI allows operators to easily manage all robot functions.
Control system features include:
- 7-inch or 10-inch touchscreen options
- Multilingual user interface
- Full synchronization with the injection molding machine
- Product memory and recipe storage
- Fast teaching (teach-in) function
- Alarm history and fault diagnostics
The control system supports flexible I/O configurations and communication interfaces, ensuring compatibility with various injection molding machine brands.
OPTIONAL FUNCTIONS AND CONFIGURATIONS
Beyond the standard configuration, Redstone series robots can be expanded with a wide range of optional features:
- 5-axis full servo configuration
- Servo-driven wrist rotation
- Dual gripper applications
- Vision systems for part detection and orientation control
- Air pressure sensors
- Sprue separation and breaking systems
- IML (In-Mold Labeling) compatibility
- IoT connectivity and remote monitoring
With these options, the robot can function not only as a part removal unit but also as the central element of a fully automated production cell.
SAFETY AND COMPLIANCE
Redstone series robots are designed in compliance with international safety standards. Both software and hardware safety layers prioritize operator protection and system reliability.
- CE compliance
- ISO 9001 quality management system
- Emergency stop and safety interlocks
- Collision detection and overload protection
