Which technical coatings are best suited for protecting railway equipment and components?
Sofiplast provides anti-wear, anti-corrosion, and dry-lubrication coatings for railway components exposed to intense mechanical stress, including axles, ball joints, suspensions, and braking systems. These technical treatments help extend equipment lifespan, reduce maintenance requirements, and ensure long-term reliability in continuous operation.
The railway industry operates under demanding conditions, including exposure to weather, constant vibrations, repeated mechanical stress, and strict safety standards. Whether for component maintenance, equipment refurbishment, or surface preparation prior to coating, durability, reliability, and operational safety are critical requirements.
To address these challenges, Sofiplast offers comprehensive surface treatment solutions ranging from eco-friendly stripping processes to the application of high-performance technical coatings. Our processes help extend component lifespan, optimize operational performance, and reduce both maintenance costs and downtime.

Technical coatings for the railway industry
Railway mechanical components, including axles, ball joints, joints, suspension systems, bearings, and braking components are exposed to demanding operating conditions such as repeated friction, heavy loads, constant vibrations, and temperature fluctuations. To ensure long-term performance and reliability, these components require enhanced protection against wear, corrosion, and abrasion.
Sofiplast offers a range of high-performance technical coatings specifically designed to meet the requirements of the railway industry:
- Fluoropolymer coatings (FEP or PFA such as Teflon® or Xylan®): excellent chemical resistance, low friction coefficient, and high-temperature stability
- Fluoropolymer coatings reinforced with PEEK additives (Victrex®): enhanced mechanical strength, abrasion resistance, and long-term durability in harsh environments
- Rilsan® polyamide coatings: excellent anti-corrosion protection, flexibility, and resistance to mechanical and thermal shock
- Sprayed polyurethane coatings: effective shock absorption, vibration reduction, and durable protection against mechanical stress
These treatments reduce friction, limit premature wear, improve component movement, and extend equipment lifespan while reducing maintenance requirements. Fully aligned with the safety, durability, and performance standards of the railway industry, they help ensure reliable operation under continuous service conditions.
Our eco-friendly stripping processes
Stripping is a key step in equipment refurbishment, surface preparation prior to coating, and preventive maintenance of metal, mechanical, and bodywork components. Traditionally performed using aggressive chemical treatments or intensive sandblasting, conventional stripping methods can damage materials and pose risks to both the environment and operator safety.
At Sofiplast, we have developed an eco-friendly stripping solution designed to protect sensitive surfaces while reducing environmental impact. This process uses plant-based media such as wheat starch, corn, and fruit shells, applied at low pressure.
This clean and non-abrasive stripping method is particularly well suited for chassis, body panels, braking systems, connectors, mechanical components, and cabin structures, ensuring optimal surface preparation before applying anti-corrosion, anti-abrasion, or non-stick coatings. With this innovative technology, Sofiplast supports railway operators in implementing more sustainable and responsible maintenance practices.
