On June 24, 2016 a major inaugural ceremony was held at the European Technical Center of DuPont in Meyrin, Geneva. The ceremony, marking the culmination of eight years of cooperation between the two companies, was attended by Pierre Maudet, minister for economy and security for Geneva; Daniel Loeffler, director at Economic Development Office for Geneva; Rolf Gobet, director of the Office for the Promotion of Industries and Technologies (OPI); as well as members of the press.

The ceremony was held to inaugurate the launch of a new machine for the blow molding of plastics, model ST Aspi SeCo that the company ST Soffiaggio Tecnica, with a production site in Stabio, in the canton of Ticino, has recently delivered to the research center of Meyrin.

The Meyrin site is the technological research and development center of DuPont, a cutting-edge space in research and technical innovation. For over 20 years now, the European Technical Centre works for the development of applications, such as, for example, blow molding air ducts, based on a collaborative approach.

This is the second blow molding machine supplied by ST Soffiaggio Tecnica, after the first delivered in 2010, and confirms the strong partnership between the two companies. DuPont, leader in automotive applications, recognizes indeed the Swiss manufacturer as a reliable partner, for its blow moulding machines.

The delivered blow moulding machine model ST Aspi SeCo is suitable for the production of parts with materials in monolayer, coextrusion or SeCo (Sequential Coextrusion), in case of need to produce items requiring different mechanical or chemical properties in predefined areas, usually for the automotive industry.

The machine is equipped with two extruders of 60 mm, two accumulator heads, respectively by 1 and 1.5 liter and a coextrusion head.

An application worth mentioning is definitely the 4WDS radial control system, integrated in this model of blow moulding machine.

This system, based entirely on the experience and technical knowledge of St Soffiaggio Tecnica allows to obtain a uniform wall thickness, also for parts of more complex shape and difficult to be manufactured.

Furthermore, the ST Aspi SeCo blow moulding machine is the only model of the ST Aspi range equipped with a shutter that allows a perfect control in the transition from one material to another, during the sequential production.

The automotive industry is, today more than ever, a highly complex and competitive market, in which the customer has assumed a very important role, especially in recent years, becoming more demanding and attentive to the smallest details. It is therefore necessary to invest in advanced machinery from a technological point of view.
