High-Quality Polymer Coating

The quality of the final coating and the performance characteristics of the painted product are key factors in competitiveness. A polymer coating must be both visually appealing and durable — offering strong resistance to wear, corrosion, UV radiation, and other aggressive environmental influences.

Key factors affecting coating quality:

• Surface preparation is critical to achieving a strong and long-lasting coating. Proper pretreatment includes cleaning, degreasing, and applying a conversion layer to improve adhesion between the metal and the powder coating. More about surface preparation.
• Coating thickness and number of layers are defined by customer requirements or industry standards. In some cases, to enhance the functional or visual properties of the finish, two layers are required — for example, primer + coating or coating + clear coat.
• Automated application ensures consistent quality and repeatable results. Using robotic powder coating systems enables even powder distribution and uniform film thickness. More about coating automation.
• Complete polymerization depends on oven performance — specifically thermal output and the length of the active heating zone. Well-designed hot air circulation ensures even temperature distribution inside the oven, leading to consistent melting and curing of the powder.

We take into account the type of product being coated, its operating environment, and the required service life. Based on these factors, we design the optimal coating process — from surface preparation to the number of layers, temperature settings, and dwell times at each stage. This results in superior coating performance and enhanced product competitiveness.

Products coated on our lines meet international standards such as ISO, ASTM, NACE, AAMA, and QUALICOAT. Quality certification confirms the high protective and decorative properties of the finish and increases the product’s value in the eyes of the customer.

• Reduced water and chemical consumption in surface treatment tunnels. An automatic cascade replenishment system ensures high reagent utilization within closed-loop cycles, eliminating discharge into the sewer system. Tunnels are additionally equipped with automatic chemical dosing units, oil separators, and solution regenerators to maintain bath cleanliness and extend the service life of chemical baths.
• Powder savings through automated application with precise control of coating thickness and high-efficiency powder spray guns. Advanced recovery systems and powder centers with automatic proportional mixing of fresh and recycled powder achieve powder utilization rates of 95 - 98%.
• Reduced energy usage through full thermal insulation of all heating stages and the use of high-efficiency burners paired with massive thermal inertia heat exchangers. Our innovations focus on maximizing heat efficiency — for example, by using combined drying and curing ovens that recover heat from cooling parts.
• Exceptionally low electricity consumption thanks to energy-efficient motors and unique engineering solutions — such as deploying multiple low-power fans instead of a few high-power ones. This ensures uniform airflow along the heat exchanger, achieving consistent heat distribution with minimal power consumption.

A fully automated EUROIMPIANTI line, designed for maximum energy and resource efficiency, delivers cost-effective, low-waste, and environmentally sustainable powder coating — at the lowest possible operating cost.

Reliability and Long Service Life

EUROIMPIANTI's reliability and durability have been proven by the successful operation of more than powder coating lines. High maintainability and ease of service are built in from the design stage, using AutoCAD. Thanks to smart engineering, our equipment has a service life of 17 to 20 years.

Key factors behind EUROIMPIANTI line reliability:

• High-quality materials. We use materials with a large safety margin. Surface preparation tunnels are made entirely of stainless steel, making them virtually "indestructible" — even when exposed to aggressive chemicals. Heat exchangers are made from heat-resistant stainless steel that withstands continuous thermal loads and expansion.
• Premium components. We apply strict selection criteria to all suppliers. Our priorities: reliability, low operating costs, and long service life. We use only trusted brands: LOWARA pumps, ABB motors, WEISHAUPT gas burners, MAHLE filters, and SIEMENS electronics.
• User-friendly controls. A computerized control panel with built-in fail-safes prevents operator errors. Pre-set programs make it possible to start or stop the line with just two taps. Smart automation with self-diagnostics helps avoid malfunctions and provides timely maintenance reminders.
• Ease of maintenance. With convenient access to all components, our lines are easy to service and designed for quick repair. Preventive maintenance is scheduled based on operating hours. Service manuals include step-by-step instructions with clear visual diagrams.

The advantages of a reliable line become even more evident over time. Long equipment life reduces depreciation and lowers maintenance costs. One of the clearest indicators of EUROIMPIANTI’s reliability is our 24-month warranty — even under 24/7 operating conditions.
