Nakata Engineering Multiplex Extruders Extruders for multi-structure profiles play an extremely important role in improving tire quality. A tire consists of a tread, sidewalls and bead section. The respective components are formed from a number of rubber compounds with properties required for specific aspects of tire performance. With multiplex extruders, the rubber profile components are extrusion molded as a single air-free, multi-layer/compound unit under high pressure. Nakata makes cold feed extruders and pin type extruders up to 250 mm. These machines are arranged in piggy back type of 2, 3 and 4 layers. Multi-layer extrusion heads have also been developed and adapted to these units. These have also been incorporated into production lines with good results.

DUPLEX EXTRUDER TYPICAL APPLICATIONS TRIPLEX EXTRUDER TYPICAL APPLICATIONS QUADRUPLEX EXTRUDER TYPICAL APPLICATIONS Click the button for a video about our Quadruplex Extruders. QUINTUPLEX EXTRUDER   Nakata Engineering recently developed a quintuplex extruder in a state-of-the-art unit for extruding tread sections using five different compounds.   A split head clamping system provides separate opening and closing of the top and bottom heads, minimizing cleaning and wastage when changing compound types. In the future, this feature will be available on all Nakata multiplex extruders.   The first Nakata quintuplex extruder will primarily be used for a Silica compound tread extrusion with one compound being electro-conductive. SPECIAL PURPOSE EXTRUDERS   Nakata Engineering will develop specially designed extruders, such as small extruder with roller head or opposed multiplex extruder to meet a customer's demand.
