After years of marketing Rotolog, a device that monitors temperatures of molds used in rotational molding, Ferry Industries Inc. has purchased the product.
Ferry, a Stow-based maker of rotomolding machines and routers, bought Rotolog from Rotosystems Ltd. of Belfast, Northern Ireland. Rotolog allows rotomolders to monitor air temperature inside the mold during processing.
Ferry has been the exclusive North American marketing agent for Rotolog since 1991. Now Ferry will build Rotolog at its Stow factory.
Jointly developed by Rotosystems and Exxon Chemicals (Canada), the device bolts on to the mold. It transmits temperature information to a computer. Software then presents the information in graphic or tabular form.
The latest version, Rotolog 3.0, operates with standard alkaline batteries.
In addition, Ferry will continue to offer the less-expensive version, with no storage of data, called Rotolog Jr.
``Rotolog provides valuable information on what is happening to the polymer during the rotational molding process,'' said Ferry President Harry Covington. ``It also provides the potential to move to the next level - adaptive control for rotational molding machines.''
Terms of the sale were not disclosed.
