Injection Molding Machines

The injection cylinder drives the linear movement of the injection screw and must deliver consistent force to inject the proper amount of material into the mold during each cycle.

Employing revolutionary Lubrication Management technology, seals act together in complex configurations to optimize friction and wear to radically increase application lifetime and reliability, while scrapers exclude external media that could damage the sensitive hydraulic system.

The mold stroke cylinder brings the platens into position prior to the molding process, thus allowing the clamping cylinder to provide the extension and retraction force for each cycle. These cylinders may only actuate a few times a day, making low stick-slip seals an important requirement.

The clamp cylinder maintains pressure on the mold to ensure parts are formed correctly. Depending on the speed of the molding process, this cylinder must work continuously in a short stroke environment. Special low friction seals can provide long life in these conditions.
