Hasco is presenting a completely revised hot runner concept that offers a wide range of options for the layout of hot runner systems, the company said.

While the different outside dimensions of the manifold blocks are standardised, the hole distances for the nozzles can be freely selected within the predefined limits, Hasco explained. The company also tailors flow channel cross-sections in the manifolds to the application.

To meet the stringent requirements for injection moulding, Hasco has combined the H4000 manifold concept with nozzles in its current range to provide high-quality hot runner systems. The Hasco turn plugs are employed for the melt channel deflections and as plugs on the manifold bars. This is said to guarantee a leak-free manifold and optimum melt passage through the deflection while ensuring the molten polymer faces only minimal shear.

The concept has various geometries, Hasco explained. Simple deflector manifolds are supplied for nozzle spacings of 35-440mm. Naturally balanced manifolds for two or four nozzles arranged in a row can be supplied with a maximum distance of 440mm between outside nozzles. Cross-shaped manifolds are designed for a symmetrical nozzle configuration on a square, with a maximum distance of 315mm for nozzle spacing. | ec
