Components Light moulds for single-component parts offer assembly, cooling outside the mould

Editor: Barbara Schulz

Processing outside the mould with neutral cycle times – that is the advantage Zahoransky Formenbau promises with its SCPS Light Mould technology. For example, assembling and cooling can be done outside the mould, the company said.

Owing to their special type of construction, SCPS Light injection moulds are said to fit into every standard injection moulding machine. SCPS stands for Servo Cavity Positioning System, also called the Walking Beam injection mould system.All the movements in the mold are servodriven with positioning accuracy independent from the machine hydraulics.

A spin-off from the patented and highly successful multi-component paternoster moulds, Zahoransky Formenbau developed the SCPS Light system specially for single component parts, the supplier explained. Outside the mould inserts or metal parts can be loaded into cassettes and fed to the injection mould. After the moulding process, the finished mouldings can be removed without any loss of cycle times, Zahoransky said.

The company added that instead of assembly work or inserting metal parts, the external station can also be used to cool the mouldings. The benefit of "outsourcing" operating steps outside the mould is claimed to be a substantial reduction in the cycle time.

The SCPS Flex is an advance development of the SCPS Light moulds. They feature several stations to outsource external processes. The first station is serving to insert metal parts, for example. After removal, the pre-moulded parts can be cooled in the second station throughout the whole machine cycle and processed further, like printed, for example.

The next step involves finishing the parts and taking them to station three where they are removed using a robot for example. According to the supplier, this flexible and modular system can be easily enlarged and extended by further stations.

As mentioned above, every movement in the mould is made with servo drives with ultimate positioning accuracy and totally independent from the hydraulics of the injection mould.

The integrated control solution developed in-house ensures that the moulds operate independent from the sequential run of the machine.

The Zahoransky control communicates with the injection mould via a Euromap interface. All mould-dependent commands including the activation of all servo axes come from its own control.
