Maplan to demonstrate horizontal injection machine for LSR application

At Fakuma 2012, Maplan will highlight its liquid silicone rubber (LSR) application: a horizontal MHF400/200edition with SILjector-injection unit equipped with the latest generation of control devices, the PC5000touch V3. The MHF400/200edition, with 2,000kN clamping force, is a high precision SILjector-injection unit working according to the FIFO-principle with active backflow barrier and greatest dosing accuracy at 100ccm dosage volume is employed for LSR-processing. The unit is available with a volume of 100, 200 and 400ccm and built extremely compactly.

The way the SILjector-injection unit is constructed allows a simple and fast cleaning of the machine for fast rubber compound change, according to the company. The injection pressure is 2.041bar for the 100ccm version. Optional for this LSR-process is a hydraulic needle shut-off nozzle, which is specifically tempered with liquid-cooled or -heated.

The LSR dosage system TOP3000S comes from Elmet. The machine is equipped with a hydraulic lifting unit, a central ejector and an active control of a double hydraulic needle shut-off nozzle. The two cavity mold has been built by Ro-Ra Moulds. LSR bracelets will be produced at Fakuma as demonstration. A Wittman servo-robot W818 with removal gripper by Ro-Ra is employed the remove the bracelets. “In the foreground,” Technical Division Manager Rudolf Eisenhuber claims, “are automation, small footprint of the machine of 3.6m² and high energy efficiency with our DCI-tempering units.”

Analogous to the vertical injection molding machines, horizontal machines are also available as “edition” and “edition-S” versions, notes Maplan. Currently available are models with 100, 200, 300 and 400 tons clamping force. The company will also exhibit two machines for TPE applications, the vertically clamping MTF220P/160editionS and a MTTF100P/40C in C-frame construction for corner overmolding.
