Improve mould tool parts ejection
To increase the speed and effectiveness of injection mould tool parts ejection, accelerated ejectors increase the stroke of selected ejector pins to a 2:1 ratio over normal ejection stroke.
UK's largest manufacturer and distributor of precision engineered standardised injection moulding tool components, DMS-Diemould, is offering a range of accelerated ejectors to increase the speed and effectiveness of mould tool ejection Manufactured by CUMSA and distributed in the UK by DMS-Diemould, accelerated ejectors increase the stroke of selected ejector pins within a mould to a 2:1 ratio over normal ejection stroke

Mould cycle counter checks lifetime condition
DMS has announced the UK availability of a new mould cycle counter that provides moulders with a mould monitoring and maintenance planning aid.
Each unit is applied to a single pin, thus helping the ejected part to clear the core.
Each cavity of a multiple cavity mould can have an accelerated pin.
The accelerated pin ejectors are easy to install due to their cylindrical shape and can even be retro-fitted into existing conventional tooling.
In addition, three standard sizes of plate accelerator, for strokes up to 34mm and forces of 125 to 500kg are also available from DMS-Diemould.
These units provide a simple and effective method of advancing a second set of ejector plates in a plastics mould tool, without the need for complicated mechanical components So users' costs are minimized and the automatic cycling on moulds with complicated undercuts and multiple ejectors is simplified.
It is recommended that assemblies should always include multiples of two units in order to ensure a balanced movement.
