Hot Runner Nozzles suit closure cap and packaging industry.
June 21, 2007 -
Model Z3145 Valve Shot nozzles are designed for processing polyolefins and styrene in shot weight range of 5-25 g. With nozzle front sealing diameter of 10 mm, body diameter of 16.5 mm, and finely scaled nozzle lengths of 80- 140 mm, it is possible to work with small cavity centers and reach difficult gating positions. Balanced filling of all cavities is achieved by simultaneous opening of valve pins after certain amount of pressure has built up.

Multi-Cavity Needle Valve Applications for the Closure Cap and Packaging Market
HASCO has developed its new Z3145/ ... Valve Shot line of hot runner nozzles especially for demanding applications in the closure cap and packaging industry. When designing the new nozzle range, particular attention has been given to the specific needs of processors in this field.
The new HASCO needle valve system allows optimum process control. Balanced filling of all the cavities is guaranteed by simultaneous opening of the valve pins after a certain amount of pressure has built up. Optimum transmission of the holding pressure is ensured, along with avoidance of stringing and drooling of melt from the gates.
The design of the nozzle also ensures long life of the gate thanks to the needle guidance being close to the gate with minimum needle stroke. To meet the industry requirement of good colour change capability, the new nozzle line has a cleverly designed gate bubble geometry.
The Valve Shot is best suited for processing polyolefins and styrene in a shot weight range of 5 -25 g. With a nozzle front sealing diameter of only 10 mm, body diameter of 16.5 mm and finely scaled nozzle lengths of 80 to 140 mm, it is possible to work with small cavity centres and also reach difficult gating positions on the article.
This line of nozzle is also particularly maintenance-friendly because of the interchangeable thermocouple and heater. Through the flexible position of the heating outlet, the nozzle components can be changed after pulling the mould plate apart on the machine. Dismantling the mould is unnecessary, thus significantly shortening downtime and maintenance.
Additionally, the needle valve pin can be changed on the machine and adjusted from the rear without dismantling the hot runner. If necessary, individual cavities can be switched off and the relevant needle can be held in the closed position.
The nozzles are supplied as standard in combination with the pneumatic needle valves Z10750/.... Alternatively, other HASCO drive systems - such as the electromagnetic drive with HASCO Z1081/... can be implemented and drive media deployed.
With the outstanding cost:performance ratio of the Z3145/..., HASCO is able to offer a manifold needle valve solution for the price of a conventional open system without compromise to quality.
Along with a long-life heater, only high-quality materials are used for the nozzle bodies, needles, needle guides and drive components. All the parts are manufactured to the finest of tolerances.
Last but not least, the high level of standardisation of this nozzle line ensures optimum availability of spare and wear parts anywhere in the world through HASCO's global service network.
