Boy upgrades IMMs with new ejector, cooling water tracking feature

Injection molding machines Dr. Boy GmbH & Co. KG supplies injection molding machines that range from micro molding units to presses with clamping forces up to about 140 tons. The line encompasses both vertical and horizontal models that are characterized by their durability, energy efficiency and compact size.  

What’s new? Two features: an electromechanical ejector and electronic tracking of the flow of the cooling water. The electromechanical ejector operates independently of the main drive of the press, provides adjustable speeds of up to 1.6 feet per second and synchronizes the ejector and part-handling movements. It will be available on the company’s larger machines — models Boy 50 E through Boy 125 E — in November; retrofits to existing equipment also are possible. The cooling water tracking feature will also be available in November as standard equipment on all Boy machines. With it, users can set target quantities and flow rates are digitally recorded, displayed and monitored.  

Benefits Precision. The new ejector provides high dynamics and synchronous movement with the mold. This results in a precise, repeatable part extraction point and “pressure-less” ejection in which parts are no longer “thrown” through the mold area, the company said. Electronically tracking the cooling water flow eliminates the problems of visual water flow monitoring, such as the inability to make precise adjustments and the need to clean and maintain a sight glass.
