Plants technical features

Painting systems depend first of all from kind of paint used, kind of support on which apply the superficial treatment and the transport system of the pieces.

Powder painting Systems

Example of the powder painting system:

Powder painting systems offer quite a few advantages, first of all nearly zero environmental impact thanks also to our high efficiency heat exchangers or make up direct burners which permits avoiding energy wastes and the total recovering of the over-spray thanks to chambers with high efficiency insulation and high recover efficiency.

Powder painting systems are usable on most of the materials, parts in steel, aluminium, zama, cast iron etc. practically on every metal surfaces.

The only limitation to the use of this system is the polymerisation temperature, which typically goes from 160°C to 180°C, hence, it is not possible to use this technology for all the pieces which do not tolerate such temperatures.

Powder painting machineries are employed mostly on metal objects. Before painting this material has to be chemically and/or mechanically “prepared and treated” to clean its surface from oils derived from production and/or oxides, powders etc. which would prevent painting from complete adhesion to the part surface.

The pre-treatment

In most of our systems we provide a pre-treatment process which guarantees the perfect cleaning of the part.

Different kinds of metal materials need different kinds of pre-treatment, depending on the substances which need to be removed from the surface, the kind of material and the adhesion endurance time required (saline fog endurance).

Our company is specialized in the production of systems for:

  • Phosphatation;
  • Chemical, mechanical, ultrasound treatments or a mixture of these methods of degreasing;
  • Acid pickling;
  • Chroming;
  • Nanotechnology application systems;
  • Fluoro-titanium and fluoro-zircon plating;
  • Washing with demineralised water obtained by anionic and cationic exchange demineralization or by inverse osmosis demineralization;

CMV projects, produces and installs the following pre-treatment systems:

  • Spray pre-treatment tunnel in stainless steel AISI 304 and AISI 3016L;
  • Pre-treatment tanks for dipping treatments, or mixed of spray and dipping systems in stainless steel AISI 304 and AISI 3016L or in plastic material;
  • Integrated pre-treatment systems with spray tunnel and sandblasting machine or in-line shot blasting machine;
  • Sandblasting or manual shot blasting chamber;
  • Manual and special washing chambers.

Drying

After the pieces have been pre-treated, its necessary the removal of the water settled on their surface, we do this operation by evaporation and we therefore provide for the installation of drying ovens.

Our drying ovens are made of insulated resistant panels in rock wool with combustion chambers based on indirect heat exchange or, on demand, with direct make up burner.

CMV projects, produces and installs the following drying systems

  • Drying ovens in line with air courtain of hot air containment;
  • Drying ovens in line with automatic closure doors;
  • Bell-shaped drying ovens.

Coating

Powder painting is applied on metal surfaces by electrostatic attraction, a phenomenon during which an electrostatically charged material acquires the power of attracting other objects (as powders).

Therefore powders are electrically charged respect to the surface on which they are supposed to adhere, before they pass through the polymerisation process.

Our systems provides the accomplishment of this process into painting booth realized in dielectric material, which prevents electrically charged powders from adhering to booth walls; in this way, the following cleening operations of the booth become extremely fast, avoiding useless stops of the system and decreasing colour changing costs..

Cabine di verniciatura

 CMV projects, produces and installs the following painting systems:

  • Painting booth in dielectric material with external emplacement;
  • Painting booth with frontal aspiration with remote filter;
  • Painting booth with built-in cartridge filter;
  • Painting booth made of steel or other metal material.

 

Contact us for a preliminary consultation

CMV offers preliminary advice to direct and suggest its Customers in the choice of the plant that best meets their needs, evaluating the best solutions according to industrial logistics, flows, the type of production and flexibility, with the objective of provide an ad hoc system with "turn-key solution".

Painting systems for pipes

The production range of CMV special systems includes the automatic painting of metal pipes.

In this type of system the tube is conveyed by a special conical roller system which automatically introduces it into an electric induction furnace which preheats it to the temperature suitable for the subsequent painting.

The tube is thus inserted inside an automatic powder cabinet which is suitably adjusted to deliver the exact quantity of powder needed to obtain the exact covering thickness required.

After the aforesaid phase, the piece is automatically cooled by a chilled water system and are unloaded automatically and stored in special transport baskets.

Solutions for energy saving

According to the technical evaluations carried out by our engineering, the magnitude of the dispersions can arrive, in case of particularly important or geometrically complex shapes, up to a maximum of 25% of the machine energy consumption, therefore eliminating said dissipations will result in a significant reduction of the costs of management of the plant combined with a considerable reduction of the environmental impact of the production line, and in particular of the greenhouse gases.

What are the greatest energy dispersions in painting systems?

From our birth to today we have created countless painting systems and each of them has different technical, productive and dimensional characteristics, but there is a need that unites all our users; have a system that offers maximum energy savings.

In powder coating systems with a continuous feed conveyor, the greatest energy losses are due to the inevitable escape of hot air from the oven ports, due to the "breaking" of the air film, designed to contain the heat from the pieces in transit in the inlet and outlet ports.

This passage, on a continuous system takes place precisely, in an uninterrupted manner, therefore the thermal losses will inevitably be huge and unfortunately, they are intrinsically linked to the production volume of the plant; paradoxically, a painting line is more productive, the greater the dispersion will be.

Solutions for energy saving


The THERMAL LOSS REDUCTION® system, a company patent of the CMV

All these considerations have therefore encouraged us to invest considerable resources in the search for a simple and innovative solution and, to date, with pride, we can present our "Thermal Loss Reduction" containment system, which totally eliminates the aforementioned thermal dispersions and today, protected by international patent N.WO/2008/12064 - DEVICE FOR THE THERMAL LOSS REDUCTION ®

risparmio energetico thermal loss reduction

This revolutionary system allows, through the help of mobile subdivision systems, managed by a particular reading system for high thermal conditions, a total closure of the inlet and outlet openings of the ovens, with clear economic and environmental advantages that surrounds us.

  1. The system is made up of two moving retracting bulkheads, an optical system that reads parts and obviously the relative movement system.

  2. The first interposing partition interposes between two racks or pieces, the minimum space required and equal to 200 mm., And accompanies the same along a special pre-chamber positioned at the entrance and at the exit of the oven.

  3. when said bulkhead has reached the end of the pre-chamber, then the piece is prepared to enter the polymerization chamber, it is lowered until it is positioned under the bed.

  4. in the meantime a second bulkhead positioned at the beginning of the pre-chamber completes the same cycle while the first bulkhead moves to the starting position
