Extrusion Line Chillers

Heli machinery production of the extrusion line chillers, also known as extruder chiller, extruder cooling device, is mainly used for plastic extruder and rubber extruder rear cooling, the product quickly cooling stereotypes, can be widely used in continuous extrusion of different cross-section of the geometric shape of plastic products, Such as sheet, sheet, sheet, hard tube, hose, bellows, profile, cable, film, composite film products such as cooling. Formed plastic, rubber extrusion cladding from the extruder head, should be immediately cooled stereotypes, otherwise it will under the effect of gravity deformation. Cooling is usually water cooling, and according to the water temperature is divided into rapid cooling and slow cooling. Quenching is the direct cooling of cold water, quenching on the plastic, rubber extruded bag shape favorable, but the crystallization of polymers, due to sudden cooling, easy to squeeze the inner layer of residual stress within the organization, resulting in the use of cracks, General PVC plastic layer with quench. Slow cooling is to reduce the internal stress products, in the cooling water tank placed in different stages of water temperature, the products gradually cooling stereotypes, the PE, PP extrusion on the use of slow cooling, that is, after hot water, warm water, cold water Three-stage cooling. As the production rate is high, and thus generally require large cooling unit.
