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.
Blown film line machines are available based on various extrusion process, like mono layer blown film plant, multi layer blown film plant, co-extrusion two layer blown film plant to produce variety of packaging materials for foodstuff, clothing, Medical, Pharmaceutical and other packaging industries.
Blown Film Machine – Mono & Multi Layer, Co-extrusion Two Layer Blown Film Machine
Multi layer blown film plant incorporate most advanced features like grooved feed sections, barrier screws, oscillating platform, stackable die, internal bubble cooling, automatic bubble cage, fully automatic surface winder etc. applicable best to the packaging film like Milk packaging film, Oil packaging film, Stretch film, Lamination film along with other packaging industries like Medical and pharmaceutical packaging, Textile and Garments Packaging etc.
Co-extrusion is the extrusion of multiple layers of material simultaneously by co-extrusion two layer blown film plant. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head which will extrude the materials in the desired form. Eg. In the vinyl fencing industry, where co-extrusion is used by blown film line to tailor the layers based on whether they are exposed to the weather or not.
Most of plastic extrusion machines manufacturer acknowledge the fact that extrusion machinery industry is making a comeback after the recent economic downturn. Extrusion Machinery Exporters are making a conscious effort to put their best foot forward with the help of latest technologies to tap the upcoming opportunities all over the world.
