Automation in Injection Moulding: Transforming Production Efficiency
Automation, the use of control systems and technology to manage manufacturing processes, has significantly transformed injection moulding operations. Automation in injection moulding streamlines repetitive tasks, increases production throughput, and reduces labour costs, making it essential for businesses aiming to stay competitive in today’s market. By automating processes like loading, unloading, part removal, and inspection, manufacturers can achieve higher consistency, reduce errors, and enhance operational efficiency.

The Role of Robotics in Injection Moulding
Robotics takes automation in injection moulding a step further, improving precision, product quality, and repeatability. Robots are commonly integrated into injection moulding to handle specific tasks such as part extraction, sprue removal, assembly, and packaging.
- Sprue Pickers: These robots remove waste material (sprue) from the mould, maintaining cleanliness and efficiency.
- Full Servo Robots: These versatile robots handle complex tasks such as part extraction, assembly, and quality control, ensuring consistent product quality with minimal human intervention.
By integrating robots, manufacturers can achieve greater accuracy and control, reducing the chances of defects in the final products. Learn more about automation and robotics in our rapid prototyping services.

Types of Robots in Injection Moulding
Robots used in injection moulding vary in design and functionality, each suited for different tasks. Here are the most commonly used types:
Cartesian Robots
Cartesian robots, also known as linear or gantry robots, operate on a three-axis system (X, Y, Z) and are known for their precision and speed. They are widely used for pick-and-place operations, parts removal, and post-processing tasks. Cartesian robots are ideal for high-speed applications and large part moulding operations due to their ease of control and handling of heavy payloads.
Articulated Robots
Articulated robots, or six-axis robots, are highly flexible with rotational joints that allow movement in multiple directions. These robots excel in intricate part removal, insert moulding, and in-mould labelling tasks. Their ability to manoeuvre in tight spaces and reach unusual angles makes them perfect for complex operations in injection moulding.
Collaborative Robots (Cobots) in Injection Moulding
Collaborative robots (cobots) are designed to work alongside human operators, enhancing productivity while ensuring safety. Cobots are equipped with sensors and safety features that allow them to adjust their operations when detecting human presence, making them ideal for tasks that require human-robot collaboration, such as machine tending and quality inspections.
Cobots offer easy programming, flexibility, and a compact footprint, making them suitable for both small and large-scale operations. Their ability to work safely with humans allows manufacturers to combine the strengths of manual labour and automation, increasing overall production efficiency.
Benefits of Automation and Robotics in Injection Moulding
Integrating automation and robotics into injection moulding offers several advantages:
- Increased Productivity: Automated systems and robots can operate continuously, speeding up production cycles.
- Enhanced Product Quality: Consistent handling and processing reduce defects, improving the overall quality of moulded parts.
- Cost Reduction: Automation lowers the reliance on manual labour, reducing operational costs while maintaining efficiency.
- Improved Safety: Robots handle hazardous tasks, reducing the risk of accidents and improving workplace safety.
