HASCO’s Hot Half and Single Needle Valve

HASCO has extended its product range of ready-to-install single needle valves with the H44201/… and H44202/… hot halves. Users will benefit first and foremost from the high efficiency and safety of the system. The entire needle shut-off unit is installed directly in the corresponding size of the mould, making it particularly easy to maintain, and is designed and produced in close cooperation with the customer for the application in question.

The hot half is ready for immediate use, as it comes equipped with Vario Shot nozzles, all the hot runner and connection components, the clamping, frame and nozzle retainer plate, and also the standard parts. The ready-to-connect system simply has to be assembled to the fixed mould plate. After connecting the system to the peripheral control and supply units, users are able to start production straightaway.

All the electrical components and pneumatic or hydraulic drives have been tested by HASCO to ensure their correct functioning and wiring. In addition, all the relevant dimensions such as the nozzle protrusion, nozzle tip and needle position, and guides and centering units are checked on coordinate measuring machines after they have been mounted. The test results are documented in the corresponding protocols. For each hot half, HASCO supplies detailed documentation with system drawings, parts lists, and installation and maintenance instructions, as well as a test report.
