Over 150 ASPI models are in use two in the U.S. Its ASPI machines produce such shapes from engineering resins with no flash using 3D suction-blow molding (they can also perform conventional extrusion blow). A particular example is air-induction pipes for turborcharged engines. They are capable of multilayer or sequential coextrusion.Īnother specialty of ST BlowMoulding is under-hood automotive ducts and pipes with twists and turns and other geometrical complexities. Two dual-head ASPI Duo machines for 3D suction-blow molding of complex automotive pipes and ducts are operating in the U.S. This machine can be supplied with one or two extruders, the second to apply a thin outer layer (10-12% of total wall thickness) containing antistatic additive for industrial safety. accumulator-head machine tailored for IBCs, where Hollo says ST BlowMoulding is a technology leader. For example, the ISIT 1313 is a special 130-m.t. They can also be configured for multilayer coextrusion with heads built by W. The heads can accommodate direct gas injection for foaming-useful for weight reduction and thermal or sound insulation. The heads, with overlapping heart-shaped design, can support 300-mm (12-in.) tooling. Overall cycle time for this machine is said to be shorter than for any other press of comparable size. A rack and pinion on the frame supports the clamp and ensures repeatable positioning. This machine has a 200-metric-ton clamp with dual tiebars, small hydraulic cylinders for open/close traverse movements, and a large cylinder for clamping. Thanks to these extruders and to variable-speed hydraulic pumps driven by an AC inverter motor, models of the ISIT series reportedly are ranked in Class 10, the highest category of energy efficiency under the Euromap 46.1 procedure for extrusion blow molding machines (less than 0.29 kWh/kg of HDPE).Īdiabatic extruders on these machines reportedly consume significantly less energy for the same resin throughput. According to the company, no barrel cooling is required for the extruder, and overall power consumption is significantly lower than for competing extruders for the same resin throughput. They are fed by a pair of 75-mm adiabatic extruders, whose thermal insulation is said to reduce heat loss to the plant environment by 90%, and whose screw design reportedly prevents melt overheating at maximum output rate. This machine features dual 10-liter accumulator heads, each able to hold 16.5 lb of HDPE. That machine has been installed at Reyes Automotive Group in San Antonio, Texas, where it is dedicated to molding auto air-conditioning and ventilation ducts (and can be observed by visitors, according to Hollo). debut at the cancelled NPE2021 show in Orlando, Fla. The highlight of the Web Exhibition was the model ISIT 1320 Duo machine, which had been planned for a U.S. blow molders are using large accumulator-head machines of the TA series with up to 400-ton clamps and up to 100-lb shots to make products like outdoor furniture, sheds, and kayaks. Four more large TA-series machines are due for delivery in the U.S. this year, with more to come in 20. One project in development is a calf shed. They are making products like outdoor furniture, sheds, kayaks and other large parts. Hollo noted that 18 of its TA and ISIT series accumulator-head machines with up to 400-ton clamps and 100-lb shot capacity have been installed in the U.S. ST BlowMoulding specializes in large machines for automotive, industrial packaging (drums and IBCs) and specialty products. sales and service support team for ST BlowMoulding ( ). Master of ceremonies for the virtual show was Ernie Hollo, of Hollo Plastics Equipment, Inc., Northfield, Ohio, the U.S. Soffiaggio Tecnica, Zaga and Meico brands), where its manufacturing, sales and service are currently located, though its headquarters are in Switzerland. The machine builder ( ) has roots in Italy (consolidating the S.T. New and upcoming machinery developments and advances in productivity, energy efficiency, ergonomics and safety highlighted WEX 2021, the Web Exhibition presented in late June by ST BlowMoulding. clamp and dual 10L accumulator heads, originally slated for display at NPE2021, is now producing auto air-conditioning and ventilation ducts at Reyes Automotive Group.
