Plastic injection molding is a manufacturing process used to produce plastic parts in large volumes, especially when the same products are made repeatedly. Because of this highly repetitive production environment, industrial robots are widely used in injection molding operations and can work continuously around the clock.

The use of robotics in machine tending helps improve overall product consistency and production efficiency. Robots equipped with pneumatic grippers or vacuum suction cups can handle newly molded plastic parts carefully and reduce the risk of damage during part removal.

Robots are also commonly used in plastic overmolding applications, where two or more separately molded parts are combined into one finished product.

This type of automation can help reduce labor and assembly costs while improving the quality, structural integrity, and consistency of the finished product.

When the mold opens at the end of the molding cycle, the plastic has cooled and solidified in the sprue, runners, gates, and cavity-formed part areas.

Modern sprue picker robots are used for the fast removal of sprues or runners from the injection molding machine. The robot can also transfer these materials into a granulator for recycling and reprocessing.

Fitmold fully understands the value of robotics in injection molding operations and the practical benefits they bring to production. With automated robotic applications, we continue to improve efficiency, consistency, and manufacturing capability in our plastic injection molding processes.
