With the runner selector the cold runner sprue can be blocked from the mould parting line or its desired alignment can be adjusted.
This is done by reinserting the treaded part after setting the desired flow channel direction or locking it in a 90, 180 or 270° position in the intended receptacle of the runner selector body.
The functional part then remains blocked in the set position.
All runner selectors have an H7 bore for using an ejector pin Ø 5 mm as an ejection aid for the cold runner.
