Plastic extrusion machinery is the equipment to carry out the plastic extrusion that is also referred as plastic processing. Plastic extrusion is the process to convert raw plastic materials into the finished plastic product. What could be the process and instruments used in this extrusion process are simple to define with complex process. Plastic raw materials which are called as resin are mixed with additives like colorants and UV inhibitors and put-up into the hopper. Hopper pushed the mixture to the feed throat from where it is passing onto the screw in barrel. The rotating screw catch-up the material flow on the screw to form uniformity that gradually melt the resin bids at the required temperature. There is unique mechanism in the barrel to define a custom temperature to melt down the resin, but at the time it prevents overheating of the polymers that can change its property for adverse effect. The good phase wise cooling system helps the barrel to maintain the melting process without changing the product quality. Ultimate it passes out to the breaker plate and to the die where the melted plastic material forms uniformity with the technological controls and pressures to define unique product shape of plastic. The die is cool down through processing at different stages. These extrusion machineries are very much useful to derive variety of plastic products like plastic pipes, plastic tubes, wire insulation, window frames and so on many plastic products.

An extruder is a machine which performs the process of extrusion. Extrusion is the process which begins by heating the stock material which includes metals, polymers, ceramics, concrete and foodstuffs. A material is pushed or drawn through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections and work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish. Continue reading →
How Plastic Extrusion Process Carried out with Extrusion Machinery
Plastic extrusion is the process to define new plastic products of required size and shape through extrusion machinery. You can manufacture various plastic products like piping, wire insulation, plastic sheet, adhesive tape, window frames etc. Plastic granules are melted and reform again by this machinery in required shape and design. In such process plastic granules or plastic raw materials are added to extruder cavity through hopper. In extruder the plastic material needs to be mixed with colorants or UV inhibitors to make them mix and stimulate the melting process. In plastic extruder cavity the temperature is so high that the raw materials molted and generated in liquid form. The temperature in heated extruder cavity is so high upto 400F. Sometimes the temperature goes above the normal required level which can evaporate the liquid. To stop vaporization, it requires to cool down the head to maintain required temperate in heated extruder. Cooling fans are used to cool down and maintain the temperature level. After attaining the required temperature for certain time for liquidation, the extruder screw enhances the pressure to move liquid plastic to the die through proper channel. This die is a frame where it store the liquid plastic material, came out of extruder with pressure. Now liquid plastic has been moved to the die for further looking in sealed water bath to solidify plastic material to form a plastic product. Sometimes dies are passed through special cooling rolls instead of water baths to make the die and product cool fast at required temperature. Continue reading →
