Why Kopp Glass Batches Glass with Munson Abrasion Resistant Rotary Mixer Video
Kopp Glass, a world leading producer of precision molded borosilicate glass, relies on a rotary batch mixer from Munson Machinery to blend more than 300 glass compositions in unlimited colors. Kopp produces its glass in small batches, typically in the range of 100 to 1,000 pieces. The powdered ingredients are mixed, melted in a pot furnace, then molded by skilled craftsmen. The mixer is a vital part of Kopp's operation. A batch may contain anywhere from five to 15 ingredients that must be mixed thoroughly in order to guarantee product quality. Sand accounts for 60-75% of a formulation and the rest of the ingredients include borax, metal oxides and various other minerals.
