Mechanical containment management systems for one guide plate with a separate adjusting
The traditional system of control for needle nozzles with shut-off system (zažehlováním) uses various types of air, hydraulic or electrical control elements, with each nozzle to always belong to one control component. The main advantage of the described method is the possibility of keeping the needle pointed to the "closed" separately for each cavity. In their own integration into the mold, it may be difficult or impossible to directly fitted with a larger number of floating controls together with the filling and cooling channels.
Nový způsob regulace pohybu prvků pomocí vodicí desky nabízí spojení veškerých výhod jednoduché hnací resp. vodicí desky s přednostmi běžné metody ovládání uzavíracích jehel. Díky vysoce kompaktnímu rozměrovému provedení uzavíracího systému a jeho mechanického vedení lze zkrátit vzdálenost mezi dutinami a formou při zachování všech kladných vlastností, které uživatelé oceňují u tradičních polohovacích systémů.
Speciální rozpojovací zařízení umožňuje oddělit jehlu od desky a současně provést i zablokování jehly v poloze “uzavřeno” pro situace, kdy je třeba pozastavit tok plastického materiálu v jedné nebo více dutinách.
Rozpojovací zařízení zahrnuje také patentovaný mikrometrický mechanismus pro seřízení hodnoty zdvihu při otevření a uzavření jehly. Vlastní práci s mechanismem. tj. seřizování zdvihu, lze provádět přímo na stroji a s přístupem od spodní desky formy.

Otevírání i uzavírání jehly vůči dutině a související seřízení zdvihu je možno korigovat zvnějšku, bez nutnosti demontáže součástí formy..
• Mechanické vedení uzavíracích systémů na jedné vodicí desce se samostatným seřizováním (patentováno)
• Zjednodušené okruhy vedení a chlazení
• Menší nároky na prostor pro uzavírací systém
• Bezproblémové použití i pro aplikace s více dutinami. Zkrácení vzdáleností/roztečí
• Přesné a samostatné seřizování zdvihu jehly přímo na stroji a s přístupem od spodní desky formy
• Možnost uzavření (výluky) jedné nebo více dutin na stroji
• Snížení nákladů na návrh a výrobu formy
