KraussMaffei and RAMPF collaborate on single-sequence IM/PUR process


Saying that a single-sequence process to injection mold a part and immediately add a polyurethane (PUR) seal is now a reality, KraussMaffei Technologies GmbH (Münich) and RAMPF Giessharze (Grafenberg, Germany) have announced that they will work together on high-pressure polyurethane processing. KraussMaffei will contributes mixing heads for high-pressure metering of very small output volumes, while RAMPF will supply high-pressure sealing foams.

By combining injection molding plus a reaction process with a PUR casting resin engineered for this specific application from RAMPF, a continuous production process is created where still-hot injection molded parts are immediately foamed with PUR material in a high-pressure process....
