Q/A

Advantage characteristics:
Cold feed rubber seal extruder: It is a kind of equipment that uses cold rubber to produce. The feeding method of the equipment is generally strong refrigeration feeding. The cold feed rubber extruder is characterized by high production efficiency and stable production. Generally, extruders are mostly used to produce sealing strips, rubber tubes and other products that can be produced by the extrusion process. The extruder is a rubber machine used to extrude treads, inner tubes, hoses and rubber profiles.

Rubber seal extrusion characteristics

1. The rubber compound is further mixed and plasticized by the rotation of the screw of the extruder to ensure that the quality of the semi-finished rubber compound extruded is more dense and uniform;

2. Wide application range, by changing the die, you can extrude rubber profiles of various cross-sectional shapes and pre-formed semi-finished products for pressing molds;

3. The extruded products have high speed and high production efficiency, which is conducive to automated production;

4. Extrusion is not limited by length, and can produce ultra-long products that cannot be manufactured by molding.


1. This machine adopts AC motor, frequency conversion speed regulation, its speed range is large, it is adaptable to the production of rubber products of different specifications, and the operation is convenient.

2. This machine uses a special reducer for hard tooth surface extruder, which has low noise, large transmission torque, reliable and stable transmission, and convenient maintenance.

3. This machine adopts cooling feed roller for forced feeding, which can process a variety of rubber strips, with large extrusion density and good product quality.

4. This machine is equipped with a dual-channel automatic temperature controller, the temperature fluctuation during heating is small, the heating temperature can be ideally selected according to different processing techniques, and the set temperature of the heated barrel and head can be automatically controlled.

5. This machine adopts barrel water heating, steam heating can also be used. The barrel adopts circulating cooling, which can cool the material instantly and reliably to prevent the material from decomposing.

Suitable for extruding various rubbers (e.g. EPDM, natural, Dingqing, butyl, recycled), used in the production of composite strips for door and window seals, automotive seals, and single extrusions, as well as construction, electrical appliances, and machinery , Water conservancy and other belt, strip, tube, plate and other shapes of dense and foam rubber products.
