COLD FEED TYPE EXTRUDERS

COLD FEED TYPE EXTRUDERS

Cold feed type extruders are constructed with specially designed screws best suited for cold feeding. The primary components of each machine are an extruder unit, a temperature control unit, a drive motor, and a temperature control panel.

  1. Ordinary temperature rubber in the form of tapes, pellets or slabs can be fed directly to the extruder, with no preheating in warming mills before the extruder.
  2. A range of screws is available for a wide variety of compound and extrusion applications.
  3. During the extrusion process, uniform temperature and plasticity is applied to the rubber compound to provide accuracy in shape and size of extruded components.
  4. Rubber feed to the extruder can be automatic, reducing the number of operating personnel.
  5. An automatic temperature control unit, with a circulating pump, controls cylinder temperature to within ±1 degree C, so the shape and size of the extruded products are uniform.

VENT TYPE EXTRUDERS

VENT TYPE EXTRUDERS

Single screw vent type extruders have screws of an original and unique design. The primary components of each machine are an extruder unit, a temperature control unit, a drive monitor, a temperature control panel, and vacuum pump.

  1. Compound can be cold fed to the feed section.
  2. A single, specialty geometry screw and vacuum pump completely vent bubbles out of extruded components.
  3. Depending on the type of compound, the screw can be replaced quickly when necessary.
  4. Because there is minimum of revolving or connecting parts, the costs of upkeep are kept low, and the machine is easy to inspect and maintain.
  5. Requires a small floor area.
  6. An automatic temperature control unit, with a circulating pump, controls cylinder temperature to within ±1 degree C, so the shape and size of the extruded products are uniform.

PIN TYPE EXTRUDERS

PIN TYPE EXTRUDERS

The pin type extruder incorporates a special design with 60 to 100 pins protruding from the cylinder wall toward the screw's center. These pins enhance the mixing and dispersing of the rubber as it is kneaded between the screw and the cylinder, making the pin type extruder extremely flexible as a universal extruder that is applicable to many rubber compound formulations for diverse applications.

  1. Applicable to a wide range of rubber compounds.
  2. Pins enhance mixing to provide high uniformity in dispersion and plasticization of material.
  3. Output is 20% to 60% higher than a conventional cold feed type extruder of the same size.
  4. Rubber can be extruded at relatively low temperatures.
  5. The low energy consumption (WH/KG) helps keep costs down, while conserving resources.
  6. System is self-cleaning.
