Milacron Plastics Technologies (www.milacron.com), a US-based supplier of plastic-processing technologies, has announced the Magna Servo injection molding machines developed by the company’s affiliate in India, Ferromatik Milacron India, will also be produced at its Batavia, Ohio manufacturing facility.

The machines have been produced in India since 2008 and have also been imported since 2009. With the rapidly increasing demand for the machine, the company has decided to expand production in the US.

“Servo-driven pumps are revitalizing traditional hydraulic technology,” commented Brian Bish, Hydraulic Machine Product Manager at Milacron.

“We’re seeing a lot of demand for our Magna Servo machines in American markets because they’re similar in price to standard hydraulics and they provide almost as much energy savings as all-electrics.”

Compared to traditional hydraulic machine, the company’s Magna Servo delivers higher energy efficiency since variable-speed AC servo motor drives its fixed-volume gear pump. The servo motor enables the pump to provide the right amount of oil necessary for every stage of the process. If necessary, the servo motor also reverses the pumping direction to reduce pressure. The pump will stop if no additional flow is needed. Thus, the system needs less energy for oil cooling while ejecting less heat into the plant.

“Pumps that are controlled with servo motors are 40-60% more energy-efficient than standard hydraulics or variable-volume types,” Bish said.

“They’re proving to be more reliable and less expensive because they have fewer moving parts.”

The highly-dynamic Magna Servo machines offers the same repeatability and control as all-electrics, delivering faster start-ups than traditional hydraulic machines.

The Magna Servo machines are available in sizes ranging between 55 to 400 tons.
