Product Introduction:

Several rows of pins are installed in certain parts of the barrel, each row is distributed in the circumferential direction, and the corresponding part of the screw has an annular groove into which the pins are directly inserted. The pins are inserted directly into these annular grooves. The glue is moved laterally, diverted and rotated by these pins.

Due to the insertion of the pins, the mixing, kneading and plasticizing capacity is increased and the length-to-diameter ratio of the screw can be reduced by 2-4D. Due to the shorter residence time of the rubber in the barrel and the heat transfer from the pins into the rubber, the temperature of the rubber output is reduced by more than 10°C.

As a result, the working speed of the screw can be increased. As a rule, the output increases by 40-70% and the energy consumption is reduced by 25-40%. The extruded products have good plasticization, and good air tightness in the section The extruded products have good plasticization, good airtightness in the cross-section, a wide range of applicable glues, and high versatility.

The company mainly produces cold and hot feed extruder barrels and screws; rubber pin cold feed screws and barrels are widely used for extruding various rubber products and supplying rubber for calendering machines. It can also be used for extruding rubber tubes, films, inner tubes, tread, wire and cable covering and filtering of rubber impurities.

The use of pins makes the mechanical processing of rubber more effective and is a major component of highly efficient and energy-saving process equipment.

We have innovated in the structure of the screw, etc. The screw has a special geometry that allows particularly difficult plasticization to be accomplished.
