Groche is showcasing its latest development at this year's Fakuma, the active non-return valve. After three years of development and evaluation, it is now running in pilot trials at several well-established customers, the supplier said. The particular feature of the active non-return valve is said to lie in its tip. It is here where the plasticised melt stream is stopped at exactly the right point “end of dosing”, without complex use of electric motors or other pieces of equipment. This is achieved with a special spring and bolt device that locks the non-return valve entirely before melt injection into the mould occurs, Groche explained.
