Staubli reveals magnetic mould clamping system

A Staubli UK (Connectors) product story
Edited by the Engineeringtalk editorial team Oct 28, 2008

Staubli has released a mould clamping system featuring adaptive clamping force technology combined with active safety management, to provide total security, fully integrated with the moulding press.

The magnetic mould clamping system, designated QMC 122 IMAG, is suitable for all sizes of injection moulding machines without modification and is fully compatible with the Euromap 70/SPI interface.

The company said that it is easy to use and provides new levels of safety, reliability and performance.

The magnetic platens incorporate independent circular pole modules, 60mm diameter on a slim plate of 51mm.

Poles are concentrated around the centre of the plate to suit a wide range of mould sizes including those with thin back plates (<13mm).

The IMAG technology actively manages and secures the clamping operation.

Software guides the operator through an interactive safety checklist prior to clamping/unclamping.

The system calculates and compares the clamping force required with the opening force, nozzle force and ejection force of the moulding machine and detects any decrease in the original clamping force.

Each mould is stored with an identification number giving quick recall of the mould parameters and original clamping force.

IMAG also integrates the safety information coming from the moulding press prior to clamping.

The system energises quickly - less than one second for 80 magnetic modules - and only requires electrical power for the clamping/unclamping operation.

The mould is secured on the machine platen by permanent magnets and will not be affected by any power loss.

QMC 122 provides the optimal clamping force through a high concentration of magnetic poles.

The honeycomb type construction provides high stiffness, strength and durability.

The design also eases maintenance; if a magnetic pole module is damaged by collision with a mould, it can easily be replaced on site.

The system will alert operators to any drop in the clamping force and indicates when a mould can still be safely clamped but will require maintenance post production, as well as moulds where the minimum clamping force cannot be achieved and attention is needed immediately to the mould back plate before production.

The IMM will be shut down if the system detects any mould movement or temperature overrun.

A data log records the last 700 operations.

Staubli product specialists are able to provide advice on all quick mould clamping requirements.
