Bunting Magnetics Co. (Newton, KS) is introducing a high temperature version of its FF Series drawer for the plastics industry. The most important feature of this new unit, says the company, is its ability to perform at 350-degree temperatures inside the drawer. The Hi Temp FF drawer is most often installed above the opening of the molding machine and plastic resin passes through the drawer to remove ferrous contaminants. This ensures a cleaner, higher quality product. It also protects the molding machine from damage due to tramp metal.
The Hi Temp FF drawer can be used in any plastic molding or extrusion application. Because the drawer sits at the opening of the molding machine, in applications where the resin needs to be dried and/or pre-heated above 300 degrees at the introduction to the molding machine, the magnets will be subjected to higher temperatures. In addition to the magnet upgrade, the Lexan viewing window has been replaced with a polycarbonate that will hold up under the higher temperature conditions.
