PLASTIC EXTRUSION PROCESS

Plastics extrusion is a continuous high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile This process starts by feeding plastic material pellets granules flakes or powders from a hopper into the barrel of the extruder The material is gradually melted...

Production Processes

Also production of storm water boxes uses the injection moulding process In injection-moulding the plastic material is fed from a hopper into the melting section of the injection-moulding machine After melting via electric heating and friction in the screw system the material is transported forward and homogenized before being injected into the mould to form the shape of the desired product...

plastic and aluminum production process ppt

polymer processing There are many processes for plastics Selection of a process depends on many factors including - Quantity and production rate - Dimensional accuracy and surface finish - Form and detail of the product - Nature of material - Size of final product In general plastics processes have three phases 1 Heating - To soften or melt the plastic 2...

How aluminium is produced

The aluminium production process can be broken down into three stages first bauxites which contain aluminium are extracted from the ground Second bauxites are processed into alumina or aluminium oxide and finally in stage three pure aluminium is produced using electrolytic reduction a process in which aluminium oxide is broken down into its components using electric current...
