Robots in injection moulding machines

Today, the moulding landscape is changing significantly. Automation and robotics have brought major changes in manufacturing processes. Injection moulding is probably one of the manufacturing sectors that have undergone quite a transformation. By automating the injection moulding machines through communicating robots, manufacturers can achieve better precision, efficiency, and cost-effectiveness in global terms. This blog post is devoted to discussing the importance of robots in injection moulding by examining categories and advantages and how they enhance overall manufacturing productivity.

Types of Robots Used in Injection moulding Machines

The robots utilized in injection moulding machines are indispensable in automating activities, from raw material loading through the extraction of finished parts. The most common types of robots found in these applications are as follows:

1. Cartesian Robots:
Commonly referred to as linear robots, Cartesian robots are the most widely used in injection-moulding machines, thanks to their basic configuration and linear movement along three axes, making them suitable for removal and stacking tasks.

2. Articulated Robots:
Robots that are articulated and have multiple joints provide much greater flexibility and more range of motion within a workcell. The robots are ideal for more advanced functions like part assembly and part inspection in injection-moulding applications.

3. SCARA Robots:
SCARA robots are best known for their speed and precision. They excel in pick-and-place and assembly jobs.

4. Robots with Six Degrees of Freedom:
This versatile robot class is used for the most intricate operations, such as trimming, welding, and polishing of injection-moulded parts.

5. Collaborative Robots:
Cobots are designed for safe cooperation between human operators. Their ability to alleviate repetitive tasks while ensuring worker safety has increased their popularity within injection moulding.

Factors to Consider While Choosing the Robots

Selecting the correct robot for mounting on an injection moulding machine requires careful consideration of many factors to give optimum performance at an economical price:

  • Payload Applicable: The robot must be able to handle the weight of moulded parts without compromising on speed or accuracy.
  • Speed and Accuracy: Different processes of injection moulding will require different levels of precision and cycle times. See to it that the robot meets these parameters.
  • Programming Simplicity: User-friendly interfaces and programming options in robots reduce set-up time and operator training costs.
  • Space Drawings: Always look at the footprint of the robot and ascertain its seamlessness into your production setup.
  • Integration Compatibility: The robot must integrate easily with your injection moulding machine and any other equipment in the production line.

How Robots Enhance Efficiency in Injection Moulding

The integration of robots in injection moulding machines significantly boosts operational efficiency by automating repetitive tasks and minimizing human error. Here are some ways robots enhance efficiency:

  • Reduced Cycle Times: Robots perform tasks like material loading, part removal, and secondary operations faster than manual labor, reducing overall cycle times.
  • Consistent Quality: Robots ensure precise and repeatable actions, leading to consistent part quality and fewer defects.
  • Increased Throughput: By working continuously without breaks, robots maximize production output and minimize downtime.
  • Enhanced Safety: Robots take over potentially hazardous tasks, reducing the risk of workplace injuries and ensuring a safer manufacturing environment.

Benefits of Using Robots in Injection Moulding

The benefits that robots bring into various types of injection moulding machines are numerous and are not limited to efficiency.

1. Savings:
Though they are initially considered expensive, robots lead to savings over the long term through the reduction of labour, decrease in waste of materials, and increased speed in production.

2. More Flexibility:
Reprogramming robots is relatively easy so they can be installed into production for a variety of tasks, making them ideal for the manufacturers with diversified product lines.

3. Greater Precision:
It carries out work with accuracy beyond compare. This becomes important for industries like automotive and medical devices, where precision is non-negotiable.

4. Scalability:
Robots help manufacturers to rise and drop production in accordance with market demands.

5. Data Integration:
Modern robots have sensors and software, which collect important information related to the manufacturing process, hence enabling their usage for predictive maintenance and optimization of the process.

Conclusion

The incorporation of robots with different types of injection moulding machines is transforming the state of manufacturing today. Be it boosting efficiency or maintaining quality, robots have played a critical role in the entire process of injection moulding. For a manufacturer, what needs to be considered while choosing one is the most significant advantages they carry as this can help them to make informed decisions and optimize their business. Embracing this type of manufacturing not only leaves the business competitive but also fast-tracks innovation.
