CARONI S.P.A.

Electrophoresis and Powder Painting is performed by a fully automated new generation painting system Pre-treatment Preparation of the surface to be painted is the key to successful painting, ensuring adhesion of the layer of paint and resistance to corrosion. Parts are pre-treated non-stop in a tunnel divided into eight stages, using environmentally friendly chemicals; the plant has already been prepared for use of the new nanotechnologies. Pre-treatments: Pre-degreasing Degreasing Rinsing Rinsing Activation Phosphatizing Rinsing Demi-rinsing Electrophoresis Electrophoresis painting is a painting surface treament which gives parts made of iron, steel and other alloys (electrical conductors) improved ability to resist corrosion. It is characterized by uniform depositing of epoxy resin on the surface of the part, ensuring long-lasting good protection against aggression from chemical agents and other factors; it also ensures improved adhesion of top coats of paint. Electrophoresis painting offers several important benefits: Uniform thickness and total covering of all parts, including sharp corners. Ability to control the thickness of the paint by adjusting application voltage and time and paint temperature. Thicknesses of 15 to 40 µ may be obtained, depending on the type of paint (the newest paints can even reach thicknesses of 60 ÷ 70 µ). Excellent resistance in saline mist tests, more than 500 hours, thanks to crystalline phosphatization pre-treatment. Good appearance and therefore top quality finish: the coating of paint is distributed perfectly over the surface. Following electroplating, treated elements are rinsed with ultra-filtered water at the rising unit in the circuit, permitting near-total collection of the paint that adheres to the elements but has not been electroplated. Electrostatic Powder Painting Powder painting is a surface finishing treatment for parts made of metal (aluminum, steel etc.) and alloys characterized by electrostatic application of powder paint which is then polymerized in a kiln. Powder painting prevents corrosion and makes the objects treated resistant to chemical and atmospheric agents. It also permits creation of a vast range of different surface colors and effects: orange-peel, embossed, hammered, etc. The powder painting procedure is ecologically sound because it significantly reduces risk to workers and the environment. Powder painting, electrophoresis or sanding: our mission is achieving excellence in our work through advanced technologies and careful choice of materials. This great care and commitment allows us to pass on the savings resulting from quality and durability to our customers.

3D design and production of tools and dies for sheet metal working represents a natural evolution of Caroni Spa’s productive process. The Caroni Study Center first assesses the customer’s requirements, then conducts an in-depth study of technical and commercial feasibility and prepares the plan. When it has been approved, the dies are created. At this point the company’s Tooling Department and Quality Service test the pressed component, which is not mass-produced until it has reached the required quality standard. The customer may of course provide the design. Design All components, dies and machinery are 3D designed with three CAD stations. In the next phase, the mathematics is sent to the processing machinery (CAM) in real time.

The LT722D laser tube cutting system offers the highest level of productivity available today, 20% higher than the standard rate on the market, combined with a unique degree of flexibility thanks to automation of all forms of regulation. These features make the system highly efficient and suitable for both small batches and large runs. With capacities up to Ø 140 mm, maximum lengths up to 3500 mm and thicknesses of up to 8.0 mm on any kind of material, with bars as long as 6200 mm, the LT722D laser cutting system offers the following features: 1.Fully automatic, programmable machine adjustment; 2.A technological database developed specifically for tubular components based on thousands of applications on file; 3.Rapid programming even by inexperienced operators with CAD/CAM Artube software; 4.Automatic bar handling cycle from bundle, including separation, measurement, cutting and unloading; 5.Minimum bar waste.
