The injection robot in the injection molding machine is used to put product parts into the injection molding machine in the early stage of product molding. After molding, through the multi-angle expansion and contraction of the robotic arm, different products are taken out and placed on the automated conveyor belt to achieve high positioning accuracy. Fully automated injection molding process with faster speed and safer performance.

What is the injection molding process of the injection robot?

Manufacturers use injection robots in the production phase of the injection molding process to increase overall productivity by automating repetitive tasks. Injection molding robots can handle raw materials such as plastic pellets or pellets by loading them into the hopper of an injection molding machine. They can assist in setting up injection molds by accurately positioning them in the molding machine and holding them in place. After the injection molding, the injection robot can remove the newly formed parts from the mold cavity and place them on a conveyor belt or designated location for further processing or packaging.

Topstar’s injection molding robot series

Topstar’s main injection robot series is EURO Cross-walking three-axis/five-axis servo robots. Unlike traditional robots, they use our “5-in-1 servo-driven robot” technology to achieve customer goals. There are demands for precision, energy saving, and intelligence. By upgrading core component technologies such as self-developed control systems and servo drives, we have achieved precise energy saving in hardware, integrated software communication, and a more comprehensive range of application scenarios.

  2. Adopt high-rigidity precision slide rails, high-strength steel belt drive, high speed, low noise, and long life.

3.32-bit CPU, complete functions, switchable multi-language operation interface, separate host design, easy to control

  1. Posture part combination design, 90-degree rotation to match different product removal; double-arm structure suitable for simultaneous use or separate use
  2. Each axis is driven by a brand-name AC servo motor and precision-grade reducer for variable speed, fast speed, and accurate positioning, and the accuracy can reach ±0.1mm.

injection robot realizes equipment management interconnection

When traditional device management realizes cross-system interconnection through network protocols, there will be factors such as signal delay, poor compatibility, and low stability. Through the open architecture of the underlying control system, Topstar enables injection molding peripheral auxiliary machines and injection molding machines to have a native language for system integration, making equipment interconnection an extension of the system. Topstar’s injection manipulator can support the host’s call signal to achieve integrated operation, and the control system automatically optimizes the removal process, thereby improving the injection molding efficiency of the production line. It solves problems such as failure to take out and equipment alarm shutdown due to ejection position deviation and uncoordinated suction time.

Benefits of using injection robots

Unlike in the past, injection robots on injection molding machines can perform repetitive automated plastic part-picking tasks with high speed and precision, thereby reducing downtime and optimizing production throughput. Unlike manual labor, they do not suffer from fatigue or performance changes, resulting in more predictable and reliable results. Consistent part quality is critical to meeting customer specifications and minimizing defects during production. They also offer more flexibility than humans and can perform various tasks, from simple pick-and-place operations to complex assembly tasks, by programming them using servo-driven control systems. This flexibility allows them to adapt to different industries’ production requirements quickly.

Implementation considerations

Don’t forget that there are several things to pay attention to when implementing an injection robot in an injection molding machine. First, one must consider factors such as machine size, configuration, and control interface compatibility to ensure integration and compatibility between the injection molding machine and the injection robot. Secondly, we must conduct a thorough risk assessment of the injection molding process. We need to consider safety during the implementation of the injection molding robot and improve safety measures such as machine protection, interlocking, and emergency stop systems. Third, when integrating the injection robot with the injection molding machine control system, one must coordinate the communication between the two systems to ensure compatibility between the robot and machine controller, facilitating data exchange and operation synchronization.
