VIOLI MACCHINE AT OROAREZZO 2026

OroArezzo is a leading international event for the goldsmith industry, where companies, experts and innovations from all over the world meet each year. It is a benchmark exhibition that brings together a system of Italian and international excellence, ranging from gold and silver manufacturing to jewelry production, up to advanced machinery and technologies.

As every year, Violi Macchine will be at OroArezzo: we look forward to welcoming you from May 9 to 12, 2026 at the Arezzo Centro Fiere e Congressi (Italy).

We will be pleased to welcome you at Hall 6 – Stand 224, where we will display our innovative technological solutions: from the processing of tubes, wires, and profiles, with hydraulic and multi-pass drawing machines and straightening machines, to technologies for precious metal recovery, such as chips briquetting machines, mills, and mixers.

Violi Macchine will also present ultrasonic cleaning systems and polishing machines.

The exhibition is an important opportunity to meet and connect with clients and partners, as well as to share ideas and innovations.

Book a meeting with our team or visit us directly at the fair!

Tube unwinding and winding systems

Tube unwinding and winding systems – mod. VM/I-AST – VM/I-ASB

In the evolution of processing small-diameter stainless steel tubes, manufacturers have expressed the need to monitor critical quality stages. This includes proper annealing in furnaces, welds inspections and the detection of potential tube defects through non-invasive checks, such as ultrasonic testing.

To do this, the tube – originally supplied in coils or reels – must be unwound, straightened to pass through the machines for the required treatment, and then rewound into coil or reel. The entire process operates continuously.

To meet these needs, Violi Macchine has developed two types of systems: one for processing tube coils and one for tube reels.

These systems are the result of the ongoing research and development efforts of the Violi Macchine team and the constant focus on the end customer’s requirements. As a result, technologically advanced solutions have been created, designed to ensure high standards of quality and reliability.

The systems offer precise speed control across the different units, improving the final quality of both coils and reels.

The centralized control console is simple and intuitive; via touch panel it is possible to save and recall processing recipes.

The systems work on a wide speed range. They are versatile for different tube types, processing conditions, and production requirements.

Particular attention has also been paid to safety aspects: perimeter fences protect the working area, and each station is equipped with openable guards to access machines.

The systems are built in compliance with applicable European regulations.

New double automatic drawing plant with cut of worked bars

Violi company always stands out in the field of tubes drawing!

Violi drawing method has been recognised as a revolutionary system since the 1990s, because it uses hydraulic forces instead of traditional pulling systems. Using these tube drawing technologies, customers can get a good hardness of the material and resistance to wear and this consequently guarantees an excellent workability of the product in machine tools. This method takes significant increase in productivity, with a considerable reduction in the metal used and thus in the processing waste. Starting from this system, Violi designs and produces fully automatic and customized systems for the tube industry. The company is thrilled to enter this world by developing fully automatic drawing systems, starting with the selection of bars and ending with their storage after drawing. The new double automatic drawing plant Violi, is born thanks to the research and development of Violi patented technologies and thanks to the fine tuning of machines listening to the needs of customers that, for production requirements, needed a drawing bench with separate and independent stations.

The plant is composed of indipendent unwinders with indepentent cutting units with clamps for Wire cutting. Unique structure with double independent drawing pull with the possibility of drawing different diameters and lengths. One exclusive system that allows the start of the drawing in a gradual manner thanks to the programming of power and speed. The ejection of tubes is automatic. They are deposited via pick places in adjacent side warehouses without interruption of the cycle. All movements are carried out safely using sensors, Photocells and metal barriers. All working data can be adjusted via the Touch Panel or by remote control. The logic of the plant, in addition to determining all processing parameters, has the possibility of entering recipes and being able to recall them as necessary.

Technical details change according to customer requirements.

CATALYTIC CONVERTERS- GET THE BEST OUT OF THEM!

The catalytic converter is an product able to remove polluting elements contained in exhaust gases of engines. 

It is a chemical reactor in which conversion reactions take place between gas and precious metals contained.

The three main metals are: platinum, palladium and rhodium and without these it would not be possible to eliminate the most harmful combustion products from the exhaust. 

Designed with an eye to increasingly sustainable production processes, the VM MC mill is the perfect machine for crushing metal-type catalytic converters.

Thanks to a hermetic system, it allows maximum enhancement and recovery of powders contained within them.
