In injection molding, the injection molding machine is the leading equipment, and the injection robot is the equipment that assists it in grasping plastic parts. Different injection molding machines have different tonnages, so other types of robots and maximum load capacities will exist. Maximum load capacity is also one of the most important factors when choosing an injection robot. This blog post will explore the maximum load capacity of several injection molding robot models and when they are suitable.

Load capacity of injection robot

Load capacity refers to the maximum weight an injection robot can bear during operation. This includes the weight of the part being processed, the EOAT, and other accessories connected to the robot arm. Multiple factors affect their load capacity, including their design, the materials used, the technology integrated into their system, and the applications they are suitable for. Load capacity directly affects their performance and the quality of molded products. Robots with insufficient load capacity may need help handling heavier components, resulting in mechanical strain and reduced precision. In contrast, robots with appropriate or higher load capacity can handle tasks more efficiently and reliably.

Different types of injection robots

EU series:

The EU series of injection robots can be divided into EU-50s, EU-80S lll, and EU-120S ll, with maximum load capacities of 3kg, 6kg, and 8kg, respectively. Lightweight aluminum alloy arms are used throughout the EU series, and the design reduces 20 structural components of the entire machine, reducing the weight by 20% compared to other materials. The main arm’s lightweight and high-strength A6061 material improves overall operating performance. At the same time, it is equipped with fixed and open operating systems. In addition, branded AC servo motors are used on each of their axes, with precision-grade planetary reducers, faster speeds, more accurate positioning, and an accuracy of up to ±0.1mm. Make them suitable for rapid prototyping industries such as 3C electronics, etc. Suitable for injection molding machines with 150-450T.

MBW series:

The MBW series can be divided into MBW-130, MBW-170, and MBW-200 lll, with maximum load capacities of 10kg, 20kg, and 50kg, respectively. Compared with the EU series, it has a larger load capacity and uses large-bore cylinders and high-power servo drive motors throughout the posture. At the same time, it maintains a compact structure to ensure the removal of large products under the moving mold. Thickened square steel is also used to provide high load and stability. In each model, a gas tank is standard to ensure a stable gas source and more stable product adsorption. They are suitable for quick disassembly or various applications such as car bumpers, large household appliance housings, etc. Suitable for injection molding machines with 550-4000T clamping force.

Technical progress in injection robot load capacity

From the load capacity of the above two injection robot series, their load capacity depends mainly on materials and structural design. The development of high-strength and lightweight materials, such as various advanced alloys, has improved their load capacity. These materials have an excellent strength-to-weight ratio, allowing the robot to handle heavier loads without affecting flexibility and speed. The structure was designed using FEA to optimize weight distribution and stress handling. This ensures the robot can support higher loads while maintaining structural integrity and precision during operation.

Practical tips for selecting an injection robot

Back to our daily production, we need to choose the right injection molding robot and the corresponding load capacity according to the products we produce and the clamping force of the injection molding machine. In your understanding and procurement process, you must carefully evaluate the specifications of different injection molding robot models, including their maximum load capacity, range, speed, and accuracy. Compare these specifications with your requirements to determine the most suitable option. Finally, budget considerations are also important. While it may be tempting to choose the best-performing model, it is crucial to balance the associated costs.

Improve your injection molding efficiency

Integrating the right injection robot, machine, and other equipment can improve overall efficiency. The incompatibility of one of them will affect work efficiency, so it is still necessary to emphasize in the end that only the right one is the most critical.
