Automated Dispensing Manufacturer Improves Product Performance

POSTED 08/05/2021

CUSTOMER
Recognized as a leader in automated liquid dispensing and coating systems, the company designs and manufactures a full line of equipment globally. They provide equipment to the automotive industry as well as the medical, process, and packaging industries. They are able to deliver precision, consistency, and flexibility to their customers in small, lightweight dispensing systems.

APPLICATION
In this application, electromechanical ball screw actuators were being used to control the stroke of a pump and force liquid through a nozzle. They needed to displace the same amount of fluids each time. Consistency during the process regardless of surface changes became critical to the effectiveness of the device and the current ball screw actuators weren’t able to provide that.

CUSTOMER CHALLENGE
The customer was struggling with performance problems on their internally designed positive displacement device. The product had a long history in the market but wasn’t producing a constant flow rate. Without consistent and controlled dispensing, the end products failed quality control tests.

SOLUTION
Previous positive experiences with Exlar products on other dispensing machines offered them a compelling alternative. When they factored in the quality issues of their existing system and the improvements they would gain, they realized using Exlar’s GTX actuators was the right choice. The GTX offered a smaller profile with less weight and lower maintenance than that of the current ball screw actuator solution.

RESULTS
They were able to save substantially on weight and space by converting to an Exlar actuator, making their product more appealing to their customers. They also improved the quality and life of that product delivering precise control and minimizing waste. Overall, the GTX was able to give them the repeatability and precision their customers expected.
