By using a pick-and-place robot to load plastic parts into the system or to place finished pieces onto a conveyor belt, industrial robots can be utilized to automate the injection molding process.
And, while human-operated injection molding allows for variety, the use of robots in the process ensures that the highest quality, accurately cut, shaped, and measured finished products are created every time.

The use of robotics provides manufacturers with a muchneeded competitive advantage, with notable improvements in both efficiency and component quality.
Robotics in Injection Molding
Plastic injection molding is a manufacturing method for making plastic parts in large quantities where similar goods are produced repeatedly, and industrial robots are used because they can perform these extremely repetitive tasks 24 hours a day, seven days a week.
Machine tending is one of the most popular applications of robotics in injection molding. Due to the labor-intensive nature of this activity and the high consistency needed in handling due to the heat-sensitive material being molded, a robot can relieve operators of repetitive work and the risk of injury.
The use of robotics in machine tending results in increased product quality and overall production capability. Robots equipped with pneumatic grippers or vacuum will ensure the safe handling of freshly injected molded parts.
Robotics in Post Processing
Robotics also play an important role in the post-processing of plastic injection molding. Many manufacturers choose to use a robotic trimming cell because it offers superior repeatability as compared to a human employee performing the same job.
By conducting several operations at the same time, the overall efficiency and flexibility of the process are increased.
The industrial robot can dispense the same amount of sealant or adhesives in a highly repeatable pattern, improving shot quality, cycle times, and waste all at the same time
