The relationship between extruder and extrusion moulding of aluminium profile

Release date:2019-03-22 09:25 Source:http://mjaupanda.com Views:

意甲下注Dalian extrusion moulding is a processing method for making various cross-section products or semi-products through the die continuously. Extrusion is used in the processing of thermoplastic plastics and rubber. It can be used for batching, granulation, rubber filtration, etc. It can be continuously produced. It can produce various continuous products such as pipes, profiles, sheets (or sheets), films, wire and cable coating, rubber tire tread, inner tube, sealing strip, etc. with high production efficiency.


意甲下注The required equipment is divided into six types: aluminium profile extruder (main work of forging and extrusion forming), infrared mould furnace (work with extruder die), long bar hot shear furnace (heating and shearing of raw material aluminium bar before extrusion), aluminium profile tractor (drawing and straight sawing after extrusion), cold bed (cutting of adjusted finished product sawing table), aluminium profile aging furnace (after finished product). Aluminum profiles need hardening equipment.


The extrusion forming process is to add granular or powdery solid materials into the hopper of the extruder. There is a heater outside the barrel of the extruder. The heat generated by the heater is transmitted to the material in the barrel through heat conduction, and the temperature rises to reach the melting temperature. Enter the cooling setting device to solidify the material on one side and keep the fixed shape on the other. Under the action of the traction device, the product can move forward continuously and obtain the final size of the product.


意甲下注Cutting is used to cut off products for storage and transportation. The key part of the extruder is mainly composed of screw and barrel. For general thermoplastics, materials are plasticized into homogeneous melts through extrusion systems. For melt feeding and extrusion moulding with chemical reactions, the main purpose is to make materials mix evenly into fluids. Under the action of screw thrust, these homogeneous fluids are continuously extruded from the die at the front end of the extruder.
