An advanced injection system for molding and assembling multiple components in one machine and mold will be demonstrated at the Fakuma show in Germany later this month. The rotary cube-mold system comes from Zahoransky Formenbau GmbH (zahoransky-group.com) in Freiburg and will be running at the booth of KraussMaffei (U.S. office in Florence, Ky.). Zahoransky’s patented technology is called the TIM Stack Mold (TIM = Total Integrated Manufacturing). It allows at least two parts to be made on a single mold.
The special feature is the two assembly platens outside the mold on either side of the machine. These platens allow assembly of different parts produced in the cube mold—or with other external parts—by snap fit, screw connection, welding, or bonding. Leak testing or inspection can also be performed with these external platens, which can index on x/y axes or rotate, as shown in the diagram. All these external operations add nothing to the cycle time, and the external platens reduce the complexity and cost of the cube mold. The cube mold itself rotates 90° in alternating mode to the right or left, transferring parts after each injection step to one of the two assembly units.
At Fakuma, a 200-ton, two-color KM CXW SpinForm system will mold push-pull dispensing closures on a 2 x 4 mold and assemble three separate parts in the mold.
