The Benefits of Automation in Injection Molding

Plastic injection molding is a common manufacturing process where melted plastic is injected into a mold under high pressure and is then allowed to cool, leaving the plastic in a desired shape. Automation in injection molding is becoming more and more popular as robotics are coming into the market and labor shortages persist. Combining various robotic manufacturing equipment and automation tools into the injection molding process yields various benefits, including quicker production times, cost savings, and more.

Types of Manufacturing Robots


Collaborative robots, or cobots, are robots that are designed to be used alongside humans. Cobots share space with employees, assisting them with processes or being controlled by a human to complete a task. Prioritizing safety, flexibility, and ease of use, these robots are there to make the job of humans easier without replacing them entirely.

Industrial Robots

Industrial robots are fully autonomous machines, meaning they require no human intervention. Typically, these robots take on repetitive, high-precision, or dangerous tasks to protect humans and direct their attention to more important tasks. They also provide a safer work environment by removing employees from dangerous situations, allowing them to focus on other tasks.

The Benefits of Automation in Injection Molding

Both cobots and industrial robots are used in injection molding, integrating automation into the process. Working with a manufacturer who has the ability to use automation in their injection molding process can yield great benefits for your company.

Quicker Production Times

Automated injection molding moves the manufacturing process along rapidly, avoiding interruptions that may be necessary when the process is done solely by a human. These systems can theoretically run 24 hours a day, resulting in faster turnaround times and more productive manufacturing.

Decreased Cost

When manufacturers implement automation into their injection molding processes, they can greatly reduce the cost of their services. As robots take on certain capabilities or jobs, they reduce the need for human workers. This reduces the labor cost for the manufacturer and allows them to offer better prices with a quicker production time.

More Sustainable

Automated robots are programmed to complete a specific task. Because the system is integrated into the robot and the actions are automatic, repeatable, and consistent, there is a significantly lower chance of a robot making an error or mistake. Since mistakes and errors are so rare in automated injection molding, there are fewer damaged parts and fewer wasted materials. When working with a manufacturer who has implemented automation into their injection molding processes, your product is created in a more efficient and sustainable manner.
