Process: Accumulator head with parison suction

If the parison is pushed out when the mold is already closed, and drawn through the cavity by an air flow, the blow molded parts will not feature any seam line nor side flashes.
This process is suitable for the production of 3-D shaped ducts, also when the sequential coextrusion of two specialized resins is required (to get different characteristics in different sections of the blow molded part). A perfect solution for the production of under-hood ducts in the automotive industry.
