Baxter_on_Press__Mask_Aug_2015_Pic_3.jpgFrom entry level to complex automation solutions, robotic automation systems are being used in plastic injection molding to increase productivity, reduce scrap, improve part quality and reduce costs. Although a large upfront investment in automation is often required, the advantages have proven to be worth the investment. Many ROI’s (return on investment) are less than 12 months.

By utilizing robotics and automation, injection molders are increasing the ability to custom-design modular cells that are ideal for specific products and product lines.  Utilizing robotics to complete as many tasks as possible, frees up time and resources for any other required hands-on process.  It also makes it possible to repeat those tasks over many cycles with consistency and predictability.

Typically robots are used in the molding process to remove parts from the injection molds, perform secondary operations and perform quality inspections. 

With automation new goals can be met like improved delivery consistency, greater preparedness for meeting delivery dates, shorter job processing times and quality related effects that result in improved quality assurance. The consistency in the process results in improved testing and measurement data which results in stronger CpK (process capability index) values.

Common Types of Automation for Injection Molding

Automated Work Cells – These are used to minimize hands-on actions, automate and multi-task a variety of functions within a given workspace. 

Robots – Robots are programmed to carry out specific repetitive actions without variation.  It is done with extremely high degrees of accuracy.  These specific repetitive actions are determined by programmed routines that specify the direction, acceleration, velocity, deceleration and distances.  The use of sprue pickers, scara robots, 3 axis traversing robots, collaborative robots and vision systems can be incorporated to manufacture plastic injection molded components.

End of Arm Tooling – is utilized by industrial robots to complete manufacturing tasks like grippers and sprue pickers. End of Arm Tooling is made to match the product being handled.
