Extruder

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 →

The Roll of Plastic Extrusion Machineries in Extrusion Process

Plastic extrusion process is well defined from ancient period. The concept is to generate the required plastic product from raw plastic material. The process seem easy is not as easy. It requires extrusion machinery to melt plastic granules or raw materials at certain high temperature like 200 centigrade along with the soluble materials to melt down the raw granules. The granules are heated and molt down in the heating extruder cavity which is operating and controlled at certain heating temperature. On completing the melting process, the liquid plastic is forced to the die by screw pressure method. This melted plastic is cooled in die to define particle shape for the product. There are various extrusion machineries applied in industries like blown film plant, extrusion coating lamination plant, raffia tape stretching plant, PP box strapping plant, PET box strapping plant, PP/ HDPE monofilament plant, sutli plant, reprocess plant, PP-TQ blown film plant etc. Each machinery contains plastic extruder for extrusion process.

Plastic Extrusion Machinery – Plastic Extrusion, Extruder

Extrusion machinery is used for various plastic processes. plastic material is used widely in many industrial products and applications like packaging, textile, garments, pharmaceutical etc. Extrusions machineries like blown film plant, blown film line machines are used for various plastic extrusion processes for production of high volume quality blown film. In this process raw plastic material is melted and formed into a continuous profile by high end plastic extrusion machines. In this plastic extrusion process, raw thermoplastic material in the form of small beads also called as resin, is gravity fed from a top mounted hopper into the barrel of the extruder. Additives such as colorants and UV inhibitors are often used and can be mixed into the resin prior to arriving at the hopper. Plastic processing machine produces items such as pipe/tubing, weather stripping, fence, deck railing, window frames, adhesive tape and wire insulation. Continue reading →
