KraussMaffei commissions largest injection molding machine to date

KraussMaffei has achieved another milestone when it successfully commissioned its first large machine with a clamping force of 5500 tons. In October 2014, the MX 5500 - 75000/75000 started production at Weber GmbH & Co. KG plant in Rhenish Haan where it produces large-volume waste containers for the global market. The scope of delivery also included another large machine from KraussMaffei via an MX 4500 - 75000.

Weber invested on these two new large machines as the company intended to produce greater capacity and become more flexible in manufacturing large-volume containers of 660 to 1100 liters. According to Helmut Guntermann, managing director at Weber the manufactue of large-volume containers for waste disposal requires the use of large molds. The high shot weights and long flow paths require high clamping forces. The new injection molding machines must also produce locking forces of at least 4500 or 5500 tons.

The machine of the MX series also offers some technical advantages as reflected in the solid design of the machine bed and the mold fixing platens as well as the lengthened and widened sliding shoes. An added bonus was the guide for the tiebars in the movable mold plate across the entire opening width of the clamping unit. In short, these technical details provide the best conditions for operation with process reliability using heavy molds of up to 150 tons.

Large machines of the MX series are principally characterized by the hydro-mechanical twin-platen clamping unit developed by KraussMaffei. It is particularly compact in design, fast in production and low-maintenance in operation.
