Extrusion blow molding is the technological process of processing polymeric materials for the growing market popularity, resulting from the increase demand for container produced manufacturing by this technique for cosmetics, pharmaceuticals as well as technical product used in the automotive industry. Implementation of the extrusion blow molding process in the work polymer processing system is determined by many factors including technological parameters, which influence the quality of a manufacturing hollow product. Obtaining a product with the most uniform wall thickness distribution is made possible by the use in the extrusion heads control systems such as VWDS. The system can change the size of the opening die gap, resulting in thickening or thinning the extruded parison in the places where the parison is blown in a different blow ratio degree, so as to avoid excessive thinning final product. In the present study was shown the effect of opening die gap on the quality blowing parts (intake manifold airflow in a motor vehicle) in relation to the value of the product weight and wall thickness in critical areas required by the customer of the product.
