Infinity bolsters clean room investment with new Engels

In the darkest days of the great recession in 2009, custom injection molding company Infinity Plastics Group built out its own cleanroom, investing $2 million in the venture. That bold decision has paid dividends and continues to fuel further growth for the company and its Infinity CleanRoom Solutions business, which recently installed two new Engel e-motion all-electric molding machines.

Engel Infinity clean room.The tiebarless 110-ton 3.67-oz shot size molding machines were installed with Staübli six-axis servo-robots in a 2000-ft2 ISO Class 7 cleanroom molding and contract manufacturing area within in Infinity CleanRoom Solutions. That business occupies 11,500-ft2 on the  Infinity Plastics Group's 14-acre manufacturing campus in Mount Vernon, IN. (Read more about Infinity's investment in clean room operations here).

Scott A. Titzer, Infinity's vice president, said its clean room unit has molded everything from surgical pump and drug delivery components to optical scanning products, orthopedics parts, and diagnostic meters and strips. The e-motion machines, which were the first new Engel presses that Infinity ever purchased, were specified with high-torque motors and high-output heater bands to allow them to run demanding, high-heat materials, like PEEK, even though medical grades of PC/ABS, PC, PP, PE are more commonly used.

In total, Titzer says the Infinity processes around 2.5-million lb/yr of materials, producing approximately 70 million parts from a total of 44 molding machines in both of its ISO-certified plants. Titzer said the final decision to go with the Engel machines was influenced by their clean-room ready design, including protective, hooded shrouds that surround the injection unit.
