Powder painting systems can be used on every metal surface. They are nearly zero environmental impact thanks to our heat control system and to the total recover of the powders which do not adhere to the product’s surface.

The system is based on different technological procedures that allow the optimisation of the part to paint.

Powder painting is applied on metal surfaces by electrostatic attraction. The entire process takes place in painting chambers built with dielectric materials.

In most of our painting plants are complete of a pretreatment system and washing able to perform such work and then make the piece perfectly clean.
The different metallic materials requiring different types of pretreatment differentiated  by, type of material, by substance for which you want to remove the from the surface, both to the time of adhesion strength desired.
Our company is specialized in manufacturing of the following pretreatment system tunnel;

• degreasing
• phosphating
• pickling
• phosphochromating
• titanium and zirconium protection
• washing with demineralized water by demineralization of cationic and anionic exchange and osmosis

CMV projects and realizes powder painting systems with the following features:

Spray pretreat tunnel

• by passing

This type of tunnel is particularly indicated for the treatment of small and medium-size pieces and, it is more used in systems with continuous monorail overhead conveyor types. All the tank of the active stages are insulated with mineral wool panels and equipped with a heating system that can be placed inside or external to the tank. A special and exclusive system of mechanical connection of the upper body panels of the tunnel ensures total waterproof, while a special profile of the panels above it completely prevents the release of water. Our tunnels are designed according to these different stages of chemical treatment and therefore made of steel. All the external components that are contact with liquid is made of stainless steel AISI 316L.

• with static cells with automatic doors.

This construction is mainly used in the treatment of large parts, and installed mainly in operating systems with conveyor type bi-rail. The separation of stages is obtained with doors made of stainless steel-tight handled external pneumatic actuators. Also in this category, our machines are all stainless steel type 304 or 316L stainless steel, and water retention and constructive methodology reflects all the characteristics of quality and resistance taken in the continuous tunnel type.

Drying ovens

• All our drying ovens are made of mineral wool insulation 200 mm. and density 80 kg/m3.
  This feature allows a working temperature of the oven to 200 ° C, the characteristic is extremely important when degassing operations are necessary in materials such as cast iron, galvanized steel or the aluminum.
  The heat generator systems are equipped with combustion Boothswith high-performance heat exchange, built in AISI 314, a "triple round of smoke" , pipes with large areas of contact “losanghe” type , a special system of panels eliminate thermal bridges.

The Our drying ovens can be:

• continuous drying ovens, , suitable for installation in systems with continuous feed peces, and then complete of air curtains or air containment of our system, protected by international patent N.WO/2008/12064: (WO/2008/129064) DEVICE FOR THE THERMAL LOSS REDUCTION. 
• Static cell doors oven with opening and closing doors, suitable for installations in step by step overhead conveyors or bi-rail overhead conveyor systems;
• bell Oven, suitable for installation in systems with continuous progress pieces, and do not require veils air containment heat or other devices.

Painting chambers

In our plants, the powder coating spray booth is an element of considerable importance, for it is truly given the function of the aesthetic result obtained is the economic cost of budget management.
We use in plant automatic booths made of dielectric material, with external work stations complete by mono-cyclone and peristaltic valve.
Cartridge Filter with final washing system, made of heavy carpentry and complete panels for the "venting", all complying with the Directive 94/9/EC, better known as ATEX.

• in dielectric materials with external emplacement;
• with frontal aspiration with remote filter;
• disposable with built-in cartridge filter;
• made of steel or other metal material;
• cartridge powder filtering systems.

Polymerization ovens

For us, the curing ovens are the heart of the whole plant them is in fact given the task to ensure uniform cooking of the piece and therefore the quality of the finished product.
As with all our systems Curing ovens are made of mineral wool insulation 200 mm. with a density 80 Kg/m3, this type of insulation allows a working temperature of the oven to 200 ° C and an air distribution plenum adjustable bulkhead, located on the floor of the oven ensures a very constant temperature distribution and uniform.
The heat generator systems are equipped with combustion chambers in heat exchange high-performance built in AISI 314, a "triple round of smoke" tubing with large areas of contact type "Losanghe", a special system of pairs of panels cancels thermal bridges.

We design and produce:

• Curing ovens generally continuous, accompanied by sheets of containment heat or air, at the request of our system is protected by international patent.
• Bell oven , suitable for installation in systems with continuous progress pieces, containment heat air curtain do not need air or other devices, but require that the pieces are placed at the right distance on local height greater than the solution "in line"
• Static cell oven with opening and closing doors, mainly used for step by step overhead conveyors or bi-rail overhead conveyor, in generally they are used in big plants.

• in line with air films;
• in line with automatic doors;
• in line with heat control system – CMV patent;
• bell-shaped;
• static.

The PLC touch screen control panels and respective driver software have been studied and projected in order to meet the specific requirements of our customers.

If you want to know in detail the whole process read the section Solutions and transport system in the section CMV painting system.

Directed to

Powder painting systems are currently the most used products in the outline painting systems in Italy and abroad.

They are particularly recommended for metal surfaces which do not need specific treatment with liquid paint, as for the automotive sector, or which do not require graphic effects obtainable only with galvanic specific treatments and special paintings.

Advantages

Powder painting offers several advantages; first of all, the total recover of the powder which does not adhere to the part surface (over spray); then, nearly zero environmental impact and finally, easy application methods make this kind of painting the most recommended and used by the most of our customers.
