PRODUCTION OF LARGE-DIMENSIONED HIGH-PERFORMANCE GASKETS

Initiated by the demand for machines that produce large-scale metal bonded rubber composite parts, engine gaskets and gaskets for battery boxes, MAPLAN has developed a new, vertical machine series. The functional specification high-lights are large platen areas, ergonomic operation and at the same time accurate injection volume control. The new MAPLAN vertical machine series SPECIAL+ MR is Stable, accurate and modular and  suitable for many challenging applications involving Large size rubber parts with close tolerance.

TWIN-RAM 560

TWIN-RAM 560 (5600 kN clamping force) uses heating  platens with size of 800 x 1500 mm designed for maximum deflection of 0.05 mm at the center of the plate. For a specific project, the clamping unit was combined with two MAP.fifo injection units with injection volume of 50 ccm located from the top of the machine. Two injection units can inject in parallel or independent of each other. These high-precision injection units make it possible to inject very small shot volumes with high precision.

In this specific case, rubber seals are bonded on cylinder head gaskets, using this special machine. The gasket consists of thin rubber lips injected around cylinder bores, fixing holes etc. over the metal gasket. The entire injection volume of rubber is only 2 x 7 ccm for one part. High-precision gaskets with vary large dimensions and that do not require post molding operations like flash removal, can be produced with these machines.

QUATTRO-RAM 700-700/850

The new MAPLAN SPECIAL+ QUATTRO-RAM 700-700/850 injection moulding machine was specially designed for the production of battery seals in the electric car industry.

You can’t produce any faster: The servo-electrically driven MAPLAN Fast Double Shuttle moves two alternating centre plates and guarantees that continuous unloading or loading is possible during the heating time. The travel speed in this process is a remarkable 600 mm per second. The long travel distance of 3200 mm is covered in just seven seconds.
