Moretto at K 2019

Moretto at K 2019

A new edition of the K fair is getting closer, an unmissable appointment for the plastic industry actors, all involved in the common goal of proposing new solutions for a sector today more than ever at the center of the controversies concerning the environmental impact and the policies of recycling.

Moretto S.p.A., leading supplier of automation and auxiliary equipment for the plastic industry, presents itself as a "partner of solutions", capable of listening to customer needs and responding effectively with dedicated and customized products.

Starting from the customer and his specific needs, Moretto provides K 2019 visitors with an overview of unique solutions and systems, consisting of energy-saving technologies and 4.0 control and management devices, essential tools for an efficient and sustainable production. A necessary approach to "win the challenge" in a market composed of customers with complex and diversified performance needs based on the sector of application and the production process.

K2019: a window on the Moretto world

As in a large stage, Moretto will exhibit the most innovative systems and products for injection moulding, blow moulding and extrusion. There are two exhibition areas in Hall 11, one specifically dedicated to the extrusion sector, with Contrex brand products, the group brand specialized in the supply of automation and control systems for blown film extrusion (Moretto Hall 11 Stand H 57, Contrex Hall 11 Stand E65).

Maximum energy efficiency even on small productions

At K 2019 Moretto presents the X Comb series of dehumidifiers, extended in the range to cover higher production needs. These mini dryers are a real combination of patented Moretto technologies: fully electric (they do not use compressed air), they are equipped with powerful turbo-compressors, zeolite technology, the Dew Point equalizer and the exclusive OTX hopper.


Particularly indicated for the drying of highly hygroscopic technical materials used in demanding sectors such as the medical, optical and automotive sectors, the X Comb dryers are the best allies in terms of efficiency and energy savings.

The ON series, with compact and robust models, is suitable for installation directly on the mouth of the processing machine, guaranteeing constant quality during the production process.

The SIDE series includes larger models up to 24 kg/h, with the installation next to the machine, to satisfy higher productions or in battery on trolley for maximum production flexibility.

As for all Moretto dryers, the Moisture Meter device, an exclusive Moretto solution for the precise in-line measurement of residual granule moisture can also be installed on the X Comb series. Moisture Meter analyzes and detects the exact content of residual moisture up to 15 parts per million.

With Moisture Meter the customer certifies that the material is perfectly dried, proof of a quality production, in line with the technical, aesthetic and functional characteristics required.

Furthermore, being able to measure and monitor the exact residual humidity level of the polymer in-line makes it possible to "optimize" processes using only the strictly necessary energy, avoiding production waste, reducing important operating costs and environmental impact.

Energy saving systems dedicated to Packaging and PET

Particular attention is paid to the drying of PET granules, a delicate phase especially for large productions, typical of the rigid packaging and beverage sectors.

In a dedicated area of the stand, Moretto presents a drying system consisting of a XD 800X series dryer combined with the OTX hopper and Moisture Meter Manager. A solution able to guarantee certifiable results, an absolute primacy in terms of energy efficiency for any type of material and a completely automatic system of the drying process.

With Moisture Meter Manager the drying process goes from an "adaptive" logic to a "responsive" cutting-edge logic. 

Another Moretto’s unique solution in the market for the drying of technical polymers.

Once again, a solution that arises from the study of the physical phenomena to which the different polymers are subjected during the drying process, developed based on years of experience and objective results of practical tests.

The innovative turbo-compressors system of the XD 800X series dryer, together with the OTX hoppers, offer extraordinary levels of energy efficiency. Furthermore, the XD 800X dryers do not use either cooling water or compressed air, being this another advantage in the treatment of PET and ensuring energy saving compared to conventional dryers.


The use of the exclusive OTX hopper allows a homogeneous flow of the material inside the hopper during the process, guaranteeing an effective and controlled drying and an extraordinary energy efficiency of + 66%, also reducing the material treatment time. In the treatment of PET in the Beverage sector, one of the aspects to which Moretto customers are most "loyal" is the constant treatment of OTX which ensures a stable process and an improvement in machine cycle times, in the order of half a second.

This is equivalent to producing up to 17 million additional preforms per year.

The application of Moisture Meter Manager integrates the dryer into a "responsive" system as required by the 4.0 intelligent factory project. Moisture Meter Manager measures the initial moisture of the granule and based on this, knowing the precise behaviour of each material, it performs the appropriate drying cycle to obtain the result requested by the customer in terms of final moisture, which is then monitored at the hoppers outlet.


In this way, Moisture Meter Manager maximizes process performance and achieves incredible results in terms of energy savings.

In addition to being intelligent and performing, they are machines with absolutely user-friendly controls with intuitive objects oriented touch screen and service friendly, with a conception aimed at ensuring facilitated maintenance, avoiding system inefficiencies over time.

New feeding and conveying solutions for micro-moulding and small productions

At K 2019 Moretto proposes a series of solutions dedicated to "micro" conveying for the feeding and conveying of small quantities of technical materials. Very compact feeders, ideal for installation on stand-alone machines, on drying and dosing systems or directly on the throat of the processing machine.

These conveying systems, like all of the Moretto range, include models specifically indicated for the use in clean rooms.

Intelligent feeding and conveying

To automatically manage and supervise the entire conveying process of small or large quantities of plastic material, One Wire 3 guarantees the greatest transport efficiency, thanks to its advanced FIFO logic.

One Wire 3 also controls those devices, which with their exclusive technologies, contribute to optimizing the granule conveying and feeding process. In particular, the Dolphin manifold unit, automatically supplies and distributes all the materials to all the machines, avoiding any risk of contamination and human error.


Kruisekontrol, an exclusive Moretto patent, which the European Patent Office (EPO) recognized as "the only automatic and intelligent system in the world capable of defining the best transport conditions for each plastic material". The uniqueness of this system lies in its ability to manage the speed of the material during the conveying phases, eliminating the peaks and the consequent formation of angel hair and wear of the pipes and adapt in a responsive way the transport conditions, differently from the various inverter systems that simply act on the air speed, but without taking into account the numerous variables that characterize each material (KK controls more than 15 parameters) and which constitute elements of strong differentiation in their behaviour in the pipe.
