The innovative modular WIT unit for 1 – 4 servo pump units

One can integrate directly in the PME cuboid MASTER up to 4 servo pump units [machine type cube MASTER: 1 - 2 servo pump units]. Due to this matter the system is more compact and easier to handle for applications with multiple cavities as the modular build up system of the cube MASTER / SLAVE -unit.

Besides the servo pump unit the cuboid MASTER contains the controller that regulates all further modules and interfaces as well as the mobile terminal with touch screen monitor for the operation of the entire system. A ball valve with 4 air pressure valves is part of the respective servo pump unit. These are assembled on an external valve terminal and installed as a unit close to the injection moulding machine.

It is also interesting that the servo pumps can be operated one by one or connected in parallel as a pair or in a group of four. A unique system arises, which can be used for four single, two bigger or for one very big mould cavity. The higher total volume flow of parallel running servo pumps can be used on the one hand for the reduction of the blow out time or to the acceleration of the pressurization before injector opening in the case of an upstream air bubble and short injection time of the melt.
