For over 30 years Violi is one of the leading factories in the production of jewellery making machine. The experience in this field allows Violi to start working with industries and precious metals recovery companies, getting the trust of national and international realities.
Violi has been committed for over 30 years to providing totally Made In Italy products. All phases of research, design and production happen in our headquarters in Monte San Savino
Violi, always interested to the needs of the market, produces a wide range of wire drawing machines from 6, 10, 12, 14 and 21 steps with cutting-edge electronic components and innovative technologies.
Equipped with fully electronic wire winding units, these machines allow to produce very thin wires with high quality standards.
The Bull Block wire drawing machines allow to draw wire and tubes of medium and large diameters from previous processes or continuous casting wire. Diameter of capstan is agreed with customers.
The wire-straightening machine with fly cutting system model VM/MRTVS-C is designed to straighten and cut to length – through a cutting system with circular saw blade or shears – metal wires or tubes with diameter up to 8 mm without stopping the advancement during the cutting operation.
The profiles straightening machines are designed and built to straighten metal bars and tubes with square, rectangular and complex shapes. The machine consists of two groups of 7 rollers all motorized. Storage of work programs for different types and sizes of profiles.
Violi’s patented hydraulic tubes drawing machines ideal for drawing metal tubes or bars with circular or complex profile. They guarantee high standards of quality and precision of the finished product. They are made in different versions of both power and useful length.
Violi also produces drawing benches equipped with pointing machines ideal for wedding rings production.
The company supplies a wide range of equipment for tubes working such as: manual or motorized manual mandrel releasing systems or tubes pointing machines.
Experience, research and developing of new technologies allow Violi to design and manufacture totally automatic tubes drawing plants.
The Violi series of hyperbolic roller straightening machine is ideal for the straightening of cold drawn metal tubes and bars with diameters between 3 and 65 mm.
Experience, research and developing of new technologies allow Violi to complete this series of standard machines with manual, semi-automatic or fully automatic tube loding/ unloading automations.
Advantages that customers find with Violi tubes straightening plants:
• Increase production;
• More precise straightening process;
• Ergonomic process management.
Violi chips briquetting machines of the VM/CTA series are ideal for briquetting chips deriving from CNC machines. They significantly reduce the volume of chips squeezing the oils they contain.
These machines allow to compact short or long chips of multiple materials such as: aluminum, steel, brass, grinding sludge and many others.
The briquetting machines of the VM CTA series are suitable for direct positioning under a machine tool or, thanks to the positioning of a shredder for the briquetting of long chips.
VM S23 Briquetting machines guarantee high production standard levels.
Precious metal chips briquetting machine
The VM GB1 briquetting machine is ideal for briquetting precious metal chips from diamond cutting, pantographs or CNC machines, with particularly small dimensions. Briquetting materials include: gold, silver, platinum and other precious metals.
On the other hand, VM CIT series are ideal for compacting chips coming from stamping processes, turning, galvanic wires and many others with particularly large dimensions.
Briquettes are deprived from oils avoiding the dipersion of precious metals during the melting process
The ultrasonic cleaners VM UL are ideal for cleaning various components in the mechanical, electroplating, goldsmithing and dental industries, in the automotive and other industries.
They can have sizes from 30 up to 230 liters and can be customized according to the needs of the customer.
The particularity of Violi ultrasonic washing machines is the high power and robustness that allow optimal cleaning and durability.
Innovative and high-performance model is the VM ULS ultrasonic cleaner with overflow water recirculation system.
Violi polishing machines VM/2P are ideal for manually grinding and cleaning precious metal objects. The innovation of the Violi cleaning machines is given by the suction system, silent and powerful, through self-cleaning filters and an absolute filter that allows to avoid any metal dispersion.
Violi ball mills are ideal for crushing dry materials of various kinds such as: ashes, melting slag, ceramics, catalysts, crucibles and refractory materials of various kinds. The process takes place in a continuous cycle by separating and filtering the dust obtained through a net.
In manual ball mills the removal of non- crushed materials happens manually. In automatic mills it comes out automatically from the side duct.
Ash mixers of the VM MX series are ideal to mix and homogenize powders coming from dry materials. These machine are easy to use and the process can be used for granular products as well.
This process allows to take samples for analysis processes.
The rotative sampler is normally applied right under a ball mill and it is used to convey a certain % of processed powder from the mill to a special duct with one adjustable nozzle.
The VM MC mill is ideal for crushing metal catalysts. It allows the maximum exploitation and recovery of the powders contained within them.
Violi designs and manufactures fully automatic systems for the recovery of precious metals from catalysts, ceramics, crucibles and many other materials. All systems are customizable and adaptable to the production needs of customers.
VM FMW microwave ovens are ideal for the carbonization of processing residues. By exploiting the principle of pyrolysis, they generate the carbonization of organic residues in the complete absence of oxygen, so as to minimize the formation of fumes and consequent emissions of toxic substances and dioxins.
The heat is ignited via microwaves to cause the product to char in the presence of an inert atmosphere within the oven chamber.
The process takes place quickly and in perfect safety.
The recovery of precious metals derived from waste processing is a key issue for the production cycle of companies operating in several fields. The VM/ STCR splitting component machine is a patented technology that allows to separate components from electronic boards. Starting from the splitting components and getting to the melting process Violi offers a wide range of machines ideal for the recovery of precious metals with great precision and ease of use.
