Production capacity/annum : 150 Thousand kg.
Plastic material in the form of granules are subjected to heat and pressure in an extruder and the semi-molten plastic is extruded through the nozzle in the form of hollow tube known as parison. Adjustments have been provided in the machine to vary wall thickness of the parison. Suitable parison is then inserted in a female mould and air blow into parison to force it against the sides of the mould. The material is then cooled before removal from the mould. The article is then trimmed to remove flashes.
