Brown Machine (Monark Rebuild) 4-Station Twin Sheet Rotary Thermoformer (2023)

The Brown Machine 4-Station Twin-Sheet Rotary Thermoformer, model R244TS, is a versatile piece of plastic machinery designed for efficient large-scale production. This used thermoformer features a non-pit, four-station rotary design with electric platen drives and a maximum sheet size of 88" x 136". It can accommodate mold sizes up to 84" x 132" and handle a max mold weight of 3,500 lbs per platen. The machine's form-platen strokes are both 50", driven by a 30HP gear-motor with a maximum travel speed of 12"/sec, and features a pressure-form rating of 277 tons. Equipped with advanced heating elements, the twin ovens in this setup utilize ceramic elements in a multi-zone configuration, ensuring precise temperature control. Each oven contains 264 elements per bank, which are manually adjustable to provide optimal heating. The clamp frame system is robust with quick-change capabilities, holding sheets securely in place while allowing for a maximum frame size of 7ft x 11ft. Control is streamlined with an Allen-Bradley Compact-Logix PLC and a 15" Red-Lion touch-screen HMI, offering intuitive operation. Additional features such as a 10HP vacuum system, substantial 500-gallon reservoirs, and sturdy construction provide reliable performance. The overall machine footprint is 35ft by 35ft, with a height of 18ft, making it a suitable choice for manufacturers needing high capacity and precision in thermoforming applications.
