Mold’n Seal technique

Inter-Connecting Injection Molding and Gasketing Units

Mold’n Seal technique

Many injection molded parts today need sealing to fulfill their function. This fact leads to a higher demand for inter-connecting injection molding machines to gasketing units. At the Arburg Technology Days scheduled for the end of March 2011, the Sonderhoff group will introduce its new “Mold’n Seal” technique. This production process comprises the in-line processing of injection molded components with subsequent application of a polyurethane gasket by FIPFG (formed in place foam gasket). For this application, Sonderhoff has developed its Fermapor K31 sealing foam family, which now allows for processing in step with injection molding.

While the process is ongoing, an articulated arm robot withdraws the warm moldings from the cavity, to move them along the mixing head of the Sonderhoff dosing unit, while the sealing system places the gasket precisely in line with the contour. The component heat speeds up reaction in the new PU sealing system, which enables the robot to immediately position the component for subsequent processing.
