Amut: New grooved feed zone

For polyethylene pipes, Amut (Novara, Italy) has changed the design of the grooved feed zone and the screw geometry on its EA 60 HP single-screw extruders so that material is more quickly conveyed and lower melt temperatures can be used. Temperature controls have also been improved to allow processors to more closely regulate melt temperature. Five models are available, all with L/D ratios of 33:1; output ranges from 350 to more than 1200 kg/hr. The manufacturer has also designed a multiple coextrusion die head with spiral distributors targeted at processing five-layer PE pipe.
