German mould making company HASCO has released a new modifiable sprue puller insert with individually configured gates.
With the new, modifiable sprue puller insert Z530/…, HASCO has supplied a blank that can be configured as required by the customer.
This allows mould makers to design and incorporate an optimally laid sprue with a freely configurable undercut.

With the longer version, mould makers can quickly and easily satisfy application specific requirements in terms of design and length.
The use of ejectors with a sprue puller hook does not pose any problems and this makes it possible to dispense with an undercut in the puller insert.
The longer guide spigot of the puller insert permits the use of gate inserts with a curved tunnel.
In this way, the sprue can be guided out of the insert during injection, and the extended guide spigot ensures optimum guidance with central injection.
The sprue puller inserts Z530/… in 1.2826, hardened to 56HRC, are ready to mount and are available in 20 different dimensions, while an anti-rotation lock ensures precise, reliable mounting.
