Single Screw Hot Feed Rubber Extruder Rubber Machinery Extruder
Rubber extruder machinery is one of the most widely used important equipments. It is mainly used in tire tread, gaskets, tape, and other rubber extrusion.
It is energy saving, high productivity, good plasitcization and refined glue quality characteristic.
Usage of Our Rubber Extruder Machine
It is mainly applied to extrude rubber and plastic products.
Features of Our Rubber Extruder Machine
1. Screw is made of best 38CrMoALA, its hardness is higher generally than HRC62 ( 60-65 ), Depth of nitrogen is higher than 0.55-0.7 mm ( 0.4-0.7 )
2. Bush is also made of 38CrMoALA, its hardness is generally higher than HRC66( 65-70 ), Depth of nitrogen is generally higher than 0.55-0.7 mm ( 0.4-0.7 mm )
3. Feeding device is made of feeding roller and feeding barrel, Feeding roller is driven by gears and its structure resembles Italy type. The rubber will never leak out,
Then it is never impossible for that the rubber enters into the bearing bush.
4. The rubber strainer can be used in different applications, including single head, doublehead, hot feed, cold feed.
5. The machine ody is equipped with a temperature retulation device. The screw and bushes are subjected to nitrogenation treatment to get enough strength and excellent wear-resistance.
6. The head is fitted with a mechanical cutter, which operates hydraulically, the operation is sample and easy.
