Extruder Drive & Motor Upgrade

Has your extruder come to a halt because of an obsolete drive or motor? Don't keep your customers waiting and let your reputation suffer. Have your process requirements changed; do you process different materials which require different performance?

Extruder Cooling Upgrade

Do you want to increase the extruder reliability and improve the process performance of your water cooled extruder?

Description

Our Water Cooled Extruder NMR 80 is designed to process thermally sensitive polymers and elastomers at low temperatures. Typical materials are semiconductive, sheathing and insulation rubbers in stripe and granular form.

Extruder barrel
The barrel material is nitrided steel nitrided to the mimimum depth of 0.4 mm. The feed section has a smooth exchangeable bushing.

Hydraulic feeding roller for stripe rubber
The rubber stripe is fed with a roller. A hydraulic unit and a motor for the roller are included.

Power transmission
An AC or a DC motor is mounted with a flange onto the gearbox body. The motor is connected directly to the primary shaft of the gearbox with gear coupling.

Temperature control system
Each zone in the extruder barrel has separate temperature control. The barrel is heated by resistors moulded in cast aluminium heating elements. The pressurized, closed cooling water system includes cooling pipes and proportional valves. The cooling pipes are wound around the barrel. The cooling system is connected to the water station. Temperature in each zone is measured by thermocouples located tangentially close to the inside surface of the barrel. The thermocouple reacts quickly to changes in the process conditions providing fast feedback control for heating and cooling. To control heating and cooling each zone has a PID-controller. The feedbox has separate cooling water circulation regulated by an adjustable ball valve.

Pressure control
Melt pressure is measured at the barrel end. The maximum allowed pressure can be preset in line control. Overpressure activates an alarm. A pressure fuse at the barrel end acts as a mechanical guard, releasing the pressure if its nominal value is exceeded. Cables between the extruder and control cabinet are included in the delivery, except the optional motor cable. Screw cooling parts with a rotating connector and hoses are included in the delivery.

Technical characteristics

Screw diameter 80 mm
Screw operation length 14-20D
Screw speed, max. 40 rpm

Exact values depend on the assembly.

Options

  • 14D long extruder for silicon rubber
  • 16D long extruder for rubber
  • 20D long extruder for semiconductive XLPE and rubber 
  • Screws for rubber in stripe and granular form
  • Screw for semiconductive XLPE
  • Hopper for granular rubber

Perfect Control of the Cable Position in Your CCV Line

16.9.2026

Over the past 30 years, Maillefer has delivered and started hundreds of catenary continuous vulcanization (CCV) lines globally. We can confirm that successful cable quality needs a perfect interaction between all the various components in a CCV line. To that end, Maillefer and Sikora GmbH, invented a means for securing the cable quality for both past delivered CCV lines and those to be delivered in the future. They named the device Siccon 600.

State of the Art Fiber Feeder

2.9.2026

The productivity of an optical cable manufacturing line can be significantly improved by increasing line speed. The buffering process has introduced entirely new limits for these speeds, making the start-up procedure increasingly important. A rapid ramp-up to production speed may generate substantial scrap before the process stabilizes. Read more
