MilacronMcKechnie Plastic Components has integrated turning-stack-mold technology from Ferromatik Milacron Europe into its multishot screwdriver molding operation in Easley, S.C.
Milacron Inc. of Cincinnati said McKecnhie invested more than $1 million in the turning-mold system, and two K-Tec injection presses, each with a clamping force of 450 tons.
McKechnie can turn out 4 million handles for the Thrifty-brand screwdrivers each month for Stanley Works.
The presses run 24 hours a day, seven days a week, using 32-cavity revolving molds.
The cube stack mold was made by toolmaker Foboha GmbH of Haslach, Germany. The cube design provides a hold station between the first and second shots, to allow some cooling and to improve control of the internal diameter of the handle. Stanley inserts the screwdriver bar at its factory.
The cube also reduces cycle time because parts can be ejected while the mold is closed.
The original Thrifty has an extruded, two-color straight handle. The redesigned, injection molded handle is trilobed, made from black and yellow polypropylene.
