MechanismBarrel & Sleeve

Wear Protected Sleeve Type Barrel

Barrel length and mounting position can be configured in various ways, due to its building-block type design.
Standard barrel, Feed barrel, Vent barrel, Side Feed barrel, Plate barrel are arranged according to the raw material and/or functionality requirements.
Barrel temperature is controlled by the control box with electric heaters and cooling water. The material of the barrel sleeve is selected according to wear resistance and corrosion resistance requirements of the material.

Wear resistance sleeve used barrel
The typical barrel materials include nitride steel. Sleeve type barrels are made of wear resistance and corrosion resistance materials of special steels to guarantee long service life.
Barrel Sleeve
Inside of barrel is sleeve type. It is used to
different materials such as wear resistance
and corrosion resistance materials according
to the raw material.
Barrel Body
Block type barrel body is used by
cubic formed forged steel block.
