Industry Challenges and Pain Points Analysis:
The injection molding automation industry, particularly multi-axis positioning mechanisms in robotic systems, is experiencing rapid development driven by the demand for higher production efficiency, product quality, and process consistency. Typical equipment in this field includes robotic arms, multi-axis linear actuators, and rotating joints, all of which rely heavily on precision and stability in motion control. As the industry advances toward fully automated, high-speed, and modular production lines, the following challenges become increasingly prominent:
- High load and low back drive requirement for precise and repeatable movements;
- Compact and modular system design to accommodate flexible production layouts;
- Energy efficiency in response to rising energy costs and green manufacturing initiatives;
- Environmental adaptability due to exposure to high temperatures, dust, and chemical environments;
- High system reliability and long service life to minimize downtime and maintenance costs.
The Key Role and Technical Requirements of Gearboxes in This Industry:
In multi-axis robotic positioning systems, gearboxes are essential components for achieving accurate and stable motion. They are required to handle high torque density while maintaining low backlash, high positioning accuracy, and fast dynamic response. Additionally, the following implicit design requirements are critical:
- High torque-to-size ratio to fit within constrained mechanical spaces;
- Long operational life with minimal wear and degradation under continuous operation;
- Low maintenance frequency to reduce system downtime and lifecycle costs;
- Environmental resistance including high-temperature tolerance and IP65 or higher sealing levels for harsh conditions;
- Compatibility with existing motor brands and control systems to support flexible integration.

Typical Application and Customer Feedback:
A major European injection molding equipment manufacturer required a high-precision and compact gearbox solution for a six-axis robotic arm used in high-speed mold clamping applications. The system needed to operate continuously in a high-temperature environment with minimal maintenance. Waimica's technical team conducted an on-site evaluation, analyzed the motion profiles, and proposed a custom hollow rotary table gearbox configuration that matched the customer's torque and accuracy requirements.
The project involved the integration of three Waimica hollow rotary table gearboxes into the robot's rotational joints. Post-implementation testing demonstrated the following performance improvements:
| Metric | Before Waimica | After Waimica |
|---|---|---|
| System Stability Rate | 87% | 98% |
| Positioning Accuracy | ±1.5 arcmin | ±0.5 arcmin |
| Mean Time Between Failures (MTBF) | 20,000 hrs | 30,000 hrs |
| Maintenance Interval | 3,000 hrs | 5,000 hrs |
| Overall Energy Efficiency | 83% | 89% |
