With competitive price and timely delivery, Litong sincerely hope to be your supplier and partner.

EUROIMPIANTI automatic conveyor lines are used in the serial production of metal products to ensure high quality polymer coatings and minimize the cost of painting.

Italian lines provide virtually waste-free technology with rational consumption of energy and resources in closed cycles. This positively impacts the environmental cleanliness of production and workplace safety.

Complete Set of Powder Coating Line

The items to be coated are hung on a conveyor and successively go through all stages of powder painting technology. The coating line includes:

1. Chemical pretreatment tunnel for surface cleaning and formation of a protective conversion layer;
2. Drying oven with intensive hot air blowing for drying parts after washing;
3. Paint booth for applying powder paint automatically or manually;
4. Powder polymerization oven to form a monolithic coating with specified aesthetic and functional properties;
5. Overhead conveyor for transporting coated items through all stages of the technological cycle;
6. Computerized PLC control panel with contact screen to monitor process parameters and control line operation.

The coating line must have a complete processing cycle, including mandatory surface chemical preparation. Without proper degreasing and the application of a conversion layer, it is impossible to achieve a durable result: the polymer coating will peel off, just like old snake skin during shedding.

The configuration of the coating line and the applied technological cycle depend on the quality requirements of the final coating. More details about the modules included in powder coating lines.

Engineering Capabilities for Customizing Lines

We have specialized in the design and manufacturing of powder coating lines since . Our design philosophy is based on a modular approach and the serial production of standardized components, which can be assembled into various line configurations. This allows us to customize the equipment to meet individual customer requirements:

• Any sizes of painted parts. We produce various types of lines for painting metal parts of any size and various shapes. From lightweight small-sized furniture components to large-scale construction structures up to 14 m long.
• Any production capacity. Based on the required product painting program, we design the required operating speed of the conveyor. By knowing the required processing time, we plan sufficient lengths of active zones at each technological stage.
• Any available energy sources. All types of combustible fuels can be used as the main energy carrier in the lines: fuel oil, diesel fuel, natural and liquefied gas. Or electricity &#; from traditional heating elements to IR emitters.
• Compact layout. Structural flexibility allows the line to be placed in rooms of any shape. We take into account regulatory requirements and the convenience of the location of loading / unloading areas of the conveyor for optimal logistics of blanks and painted products.
• Possibility of upgrading lines throughout their operation. Our customers can increase line capacity as their paint program grows, change surface preparation cycles, or simply move lines to new industrial premises.

Lines are assembled from standard components like a construction set. Exclusively bolted connections are used, avoiding welding, which simplifies the assembly / disassembly of the lines. Read more about the advantages of modularity.

High Quality Polymer Coating

The quality of the final coating and the consumer properties of the painted products are important factors for competitiveness. The polymer coating must be aesthetic and durable &#; with high resistance to wear, corrosion, ultraviolet radiation, and other aggressive influences.

Main factors influencing the quality of the finishing coating:

• Surface preparation plays a crucial role in ensuring the strength and durability of the coating. Proper cleaning includes removing contaminants, degreasing, and forming a conversion layer to enhance adhesion between the metal and powder coating. More about surface preparation.
• The coating thickness and the number of applied layers are determined by customer requirements or industry standards for the final product's application. In some cases, to enhance the functional or aesthetic characteristics of the coating, the application of two layers may be required: primer + paint or paint + clear varnish.
• Automatic paint application ensures consistent coating quality and process repeatability. The use of reciprocators and robotic systems enables even powder distribution for uniform coating thickness. More about paint automation.
• The completeness of polymerization directly depends on the characteristics of the oven: thermal power and the length of the active &#;hot&#; zone. Properly organized circulation of hot air ensures uniform heat distribution throughout the oven, which promotes uniform melting and polymerization of paint.

We take into account the category of the product being painted, its operating conditions and the required service life. Considering all these factors, we propose the ideal painting technology &#; the surface preparation cycle, the number of coating layers, temperature conditions and processing time at each stage. As a result, we increase the quality and competitiveness of our customers&#; products.

Products painted on our lines comply with international standards ISO, ASTM, NACE, AAMA and QUALICOAT. The presence of quality certificates makes it possible to document the high protective and decorative characteristics of the coating and increase the consumer value of the painted products.

Minimum Cost of Polymer Coating

Minimizing the cost of coating is the main criterion for the efficiency of painting lines, which underlies all our engineering developments and innovations. We guarantee the achievement of the required coating quality with minimal material and energy consumption.

We implement resource-efficient and energy-saving technologies:

• Saving water and chemicals in surface preparation tunnels. The automatic cascade replenishment system for baths ensures a high degree of reagent utilization in closed cycles without drainage into the sewer system. Additionally, the tunnels are equipped with automatic reagent dispensers, oil separators and regenerators to maintain the cleanliness of the baths and extend the lifespan of chemical solutions.
• Saving of powder paint due to the automatic application method with precisely controlled coating thickness and the use of sprayers with a high powder transfer coefficient. Thanks to resource-efficient recovery systems and the utilization of powder centers with an automatic proportional mixing function for fresh and recycled powder, the powder paint utilization rate reaches 95-98%.
• Energy carrier savings through complete insulation of all "hot" stages and the use of efficient heat generators in combination with massive thermo-inertial heat exchangers. Our innovative know-how is aimed at the most rational use of thermal energy &#; for example, combined drying and polymerization ovens with the possibility of utilizing the heat from cooling parts.
• Record-low electricity consumption is achieved through the use of energy-efficient electric motors and unique engineering solutions, such as the utilization of numerous low-power fans in the ovens. As a result, the heat exchanger is uniformly ventilated along its entire length, ensuring even heat distribution with minimal energy expenditure on air circulation.

A fully automated EUROIMPIANTI line with high resource and energy consumption efficiency ensures economically efficient and virtually waste-free, environmentally friendly production with minimal coating costs.
