Macchi chooses Gefran to enhance the production efficiency of its extruders

To enhance the production efficiency of its extruders, Macchi relies on Gefran as a trusted partner thanks to a complete package of solutions, among which the Melt pressure sensors with IO-Link digital output stand out.

Melt pressure transmitters with IO-Link digital output optimize the entire extrusion process, including from an industry 4.0 perspective. The precise detection of fluid pressure even at high temperatures is essential in maintaining the quality of the finished product. In addition, the IO-Link interface permits a series of substantive data for predictive maintenance to be acquired. Information such as the values of the maximum pressure and temperature peaks recorded, the total hours the sensor has operated under pressure and the calibration deviation thresholds, allow the development of algorithms capable of ensuring better productivity while at the same time guaranteeing a longer life cycle of the extruder.

Macchi was one of the first companies on the market to opt for greener solutions, replacing mercury filling technology probes with ones having zero-impact from an environmental point of view. The choice fell on the ILI series using innovative Impact technology without filling fluid, with membrane thickness 15 times higher than the traditional versions and ILK, with mixed Sodium and Potassium filling. A complete range of sensors, PLd and SIL2 certified, capable of operating in critical processes with temperatures even higher than 500° C.

The digital transformation of the sensors installed in the Macchi plants is completed with the Gefran WPL series position transducers. Equipped with Hyperwave magnetostrictive technology and IO-Link digital output, these sensors can record a large number of parameters following industry 4.0 protocols while simultaneously ensuring absolute linear precision even in the presence of shocks, vibrations and electromagnetic disturbances.

Finally, Gefran Solutions guarantees integration of all the systems that make up the extruder, completing the supply of components with a high added value consultancy service for the design, development and construction of electrical panels. On top of this, constant support is provided to Macchi’s R&D division in the creation of ad hoc, multi-platform software for line management in a constant evolutionary process of management logic and process automation. Recotrim stands out among the lines involved in this synergy: a unique pelletizing system designed to allow in-line recycling of the side trims produced during film extrusion. In this regard, Cristiano Procopio, Macchi’s R&D Director, states: "The combining and sharing of Macchi and Gefran’s R&D know-how increasingly help the extruders perform at a high level".

"In addition to extreme reliability in terms of product quality and reduced lead-time, the consultancy aspect is for us the real plus coming out of the collaboration with Gefran. From sensors to automation platforms, providing constant assistance even remotely, Gefran is a qualified Partner, capable of proposing innovative solutions and supporting us both in the development of new lines and in the revamping of existing plants, with great flexibility and professionalism. This is a result with its roots in a synergy based on mutual respect as a starting point, shared by both realities, in the name of excellence”, Matteo Spinola, Macchi's Sales & Marketing Director declares.

"Macchi and Gefran are two technological leaders in their respective sectors, who put quality at the forefront of continuous innovation. We therefore thank the Macchi Company for the constant trust it places in us", comments Renzo Privitera, Gefran’s Italian Sales Director for Sensors and Components.
