Extrusion blow molding machines

Blow molding machines are machines for the production of hollow and tree-dimensional goods from thermoplasts (tanks, barrels, large bottles, small bottles, toys et setera) by the method of blow molding. The production of goods by this method could be divided into to stages : at first we get pipe workpiece with a temperature a little below than temperature of molding and then it is blown by compressed air. Due to the large productivity and high level of automation this metod is presently the basic method for shaping of hollow goods and, as a result of some improvements allows to get goods with volume from units of milliliters to tens and even hundreds of liters.
