The Difference Between Rubber Extruder and Sealing Strip Extruder

Generally, the rubber extruder used for rubber tube extrusion is a pin-type rubber extruder with a screw barrel. The pin-type rubber extruder can fully mix and press the rubber within a limited screw length, and it is better for the rubber. Carry out plasticization and extrusion. The pin screw structure makes the produced hose have advantages in terms of surface and production efficiency.

Compared with the pin type extruder, the ordinary vented cold feed rubber extruder has a longer screw, which is suitable for the production of rubber products with relatively strict rubber characteristics such as sealing strips or rubber round bars. The type rubber extruder can be vacuumed, which can effectively solve the effect of the residual gas in the barrel on the product.

Whether it is a pin-type rubber extruder or an ordinary vented rubber extruder, the characteristics of the product should be selected according to the product, and the equipment should not be selected blindly.
