Parison Suction Blow-Molding Machines - ASPI Series
Blow Moulding Machines
General Features
ST BlowMoulding is one of the world's leading manufacturers of extrusion blow-molding machines with parison suction technology, not only in terms of the number of machines delivered but also through its undisputed technological leadership. This success is the result of continuous research and development conducted over the past 15 years in cooperation with the most demanding customers in the automotive industry.
The extrusion heads are specifically designed for engineering polymers used in the production of 3D ducts in the engine compartment, especially air-intake ducts for turbocharged engines. The special 4WDS system, which enables asymmetric radial control of parison wall thickness, provides extremely fast and precise movement. This delivers exceptional wall-thickness accuracy and consistently high quality in blow-molded parts.
In ASPI SeCo sequential co-extrusion versions, a parison is formed with two different plastic materials alternating in the sequence defined in the mold recipe. This makes it possible to produce blow-molded parts with different mechanical properties along their axis. The technology is an ideal solution especially for 3D engine-compartment ducts, reducing the number of parts to be assembled and the associated costs.
For customers requiring higher output, ASPI DUO provides the ideal solution. A moving extrusion platform travels between two clamping units, alternately transferring the parison to two molds. This doubles 3D duct production capacity while preserving the ease of use, fast setup and process stability of single-clamping-unit machines.
ST BlowMoulding's latest developments focus on production traceability, self-diagnostics and automatic process control. Technologies developed in this area include the new-generation D-Print parison marking system, delivering up to 100 times the performance of previous standards in both precision and speed; W-Print, which writes data directly onto the parison and enables it to be read from the final blown part; and the Parison Swell Detector, an optical-sensor system that continuously monitors parison diameter.
With technology this advanced, it is no surprise that the ASPI name has become synonymous with parison suction technology.
