Single and Multi-Head Extrusion:

Nakata Engineering offers single head and multiplex systems incorporating up to five extrusion heads including their innovative Chimney Band static discharge head for silica compound extrusion.  Single head and duplex systems are configured vertically, while triplex and quadraplex machines can be ordered in vertical or horizontally opposed configurations.   As the names imply, duplex, triplex and quadraplex machines handle 2, 3 and 4 compounds respectively in the same extrusion.

The Nakata Quintuplex extruder can handle up to five different compounds in a single extrusion including the Chimney Band static discharge head for silica compounds.

All Nakata Extrusion machines are engineered to the highest standards with customer requirements in mind.  Nakata machines feature:

  • Heavy Duty Clamping System – Developed exclusively by Nakata for stable high pressure extrusion this system features a stronger head clamp with a large hydraulic cylinder actuating a wedge style locking mechanism in multiple configurations.
  • Quick Changeover – Final die swap over is accomplished with the pre-former still clamped for one-minute changeover and prevention of rubber leakage between the head and tool.
  • Durable, Reliable Feed Roll – Nakata exclusive design prevents rubber leakage and ensures longer life and stable feed. Integrated or dual drives available per customer needs.
  • Hybrid Hydraulic Unit – Work environment friendly hydraulic unit reduces noise below 70dB while consuming less energy and incorporating a smaller fluid tank than conventional hydraulic units.
  • Compact TCUs – Powerful control units are size efficient and are available with local mounting on base plate on some machines for quick set-up and minimal footprint.

BPS Engineering will house common spare parts for all Nakata systems and machines in our Greenback, Tennessee, USA facility for quick, accurate delivery.  We will also coordinate sales and shipment of less common parts direct from Nakata, Japan.  Call us for all of your Nakata Engineering spare parts needs for North, South and Central American facilities.
