Coating solutions that extend product life and value

From the very beginning of the design process, we take the component’s geometry into account to enable optimal surface finishing. Once manufactured, each part undergoes a carefully controlled, multi-stage surface treatment process that ensures consistent quality and long-term reliability.  

In demanding environments where failure is not an option, reliable corrosion protection is essential. Our multi-stage surface treatment ensures that every component performs safely and consistently, year after year.  

1. Mechanical pre-treatment

The first step is steel shot blasting. This removes oxides from laser cutting and cleans off welding residues and other surface contaminants. It leaves a clean and even surface, which is important for the next stage in the process.  

2. Chemical pre-treatment

In this 10-step chemical treatment, the component is cleaned and treated with zinc manganese phosphate. This forms a protective layer that improves corrosion resistance and helps the following coatings stick better to the surface. 

3. Cathodic E-coat

The third stage is cathodic electrocoating, where a thin and even primer layer is applied to the entire component. This coating covers all areas of the part, including complex shapes and inner surfaces. It provides strong corrosion protection and creates a reliable base for the final powder coating. 

4. Powder coating — finishing

For some products, the final step involves the application of a powder topcoat, followed by curing in a high-temperature oven. This results in a hard, durable, and chip-resistant surface that is designed to withstand the test of time, providing lasting protection and aesthetic appeal. 

Why choose powder coating as a surface treatment? 

Powder coating is a durable and reliable surface treatment that provides long-lasting protection and a consistent, high-quality finish. It is free from harmful solvents and offers a more environmentally responsible alternative compared to many conventional coating methods. 

For industrial applications, particularly in the automotive sector, powder coating as part of a multi-stage process offers clear benefits. It reduces maintenance needs, extends the product’s service life and helps preserve surface integrity under demanding conditions. As a result, it delivers a higher Return on Investment (ROI) by lowering total cost of ownership over time. 

From the moment a vehicle or system leaves the production line, components treated with this method are more resistant to wear, stone chipping and mechanical stress. The finish remains intact for years, even in harsh environments, contributing to long-term product value. 

The surface treatment used for Ringfeder products is engineered to meet the automotive industry's highest standards for corrosion protection and visual performance. It ensures safety, durability and a professional appearance throughout the product lifecycle.
