Rubber seal strip extruder

Cold feeding rubber seal extruder: It is a kind of equipment that uses cold rubber to produce. The feeding way of the equipment is generally strong refrigeration feeding. The cold - fed rubber extruder is characterized by high production efficiency and stable production. Generally, extruder is used to produce seals, rubber tubes and other products that can be produced by extrusion process. Extruder is used for extruding tread, inner tube, rubber hose and rubber type strip rubber machinery.

Rubber seal strip extruder

1. Working principle

Extrusion molding is a process in which the plastic material is continuously pressed out through a mouth shape under specific conditions, so that it becomes a product with a cross-section shape.

When the rubber material moves forward along the screw, due to the result of mechanical action and thermal action, the viscosity and plasticity of the rubber material have changed and become a viscous fluid. According to the change of rubber in the extrusion process, the working part of the screw is generally divided into feeding section, compression section and extrusion section according to its different functions.

2. Cold feeding extrusion

Advantages: save heat refining equipment, easy to realize mechanization, automation, and because the main engine strengthens the shear and plasticization of the screw, so that the rubber material to obtain uniform temperature and plasticity; Improve the quality of extruded products, increase the surface finish, extruded semi-finished products have more stable and consistent size; The cold feeding pressure is less sensitive and flexible. The investment and production cost of cold - feed extruder is lower.

3. Equipment characteristics

Suitable for extruded rubber (EPDM, natural, butyl green, butyl, regeneration), used for building doors and Windows sealing strip, automotive sealing strip composite strip, single extrusion strip production and construction, electrical appliances, machinery, water conservancy and other different shapes of strip, strip, tube, plate and other dense and foamed rubber products.
