Rubber Pin screw barrels are widely used in extruding all types of rubber products and in supplying rubber to calenders. They can also be used extruding rubber tube, rubber film, inner tire,tire surface cover, rubber wire, rubber cable and so on. Pin makes rubber machine-finishing more efficient and is a major component for high efficient and energy-saving equipments.

Planetary screw is able to perform serveral times better on plastification, homogeneity, output and self-cleaning.

When big output like 500~5000kgs/h is essential to your factory, or you are preferring less or easier machine maintainance; or your customers are criticial on plasticizing quality, or a longer lifetime is expected, planetary screw barrel is a great option.

Popular sizes icnlude Ø125, Ø138, Ø150, Ø170, Ø190, Ø220, Ø250, Ø300, Ø355.
