Surface treatment
Surface treatment is a key part of delivering high-quality products that meet our customers’ demanding requirements. That’s why we’ve made significant investments in a broad range of in-house surface treatment capabilities.
Our services include grinding, blasting, and electropolishing, as well as chemical surface treatments such as pickling and passivation – all performed to ensure optimal cleanliness, durability, and performance of stainless-steel parts.
Grinding
Grinding is a key step in ensuring the high-quality surface finish required by our customers in demanding industries such as life science, pharmaceutical, and food processing. We offer both manual and semi-automated grinding solutions, giving us the flexibility to handle a wide range of part geometries and surface requirements.
Each workstation is equipped with its own dedicated grinding station, minimizing internal transport and significantly reducing the risk of scratches, handling damage during processing.
To meet industry-specific demands, Texor exclusively uses AOF (Animal Origin Free) grinding and polishing compounds, supporting compliance with life science and hygienic production standards.
Our grinding processes are capable of achieving surface finishes down to Ra 0.2 µm, ensuring the smoothness and cleanliness required for high-purity and validated systems.
Blasting
We offer both stainless steel ball blasting and glass bead blasting to achieve the desired surface texture and cleanliness on parts. These processes are essential in preparing surfaces for further treatment, improving aesthetics, or ensuring uniform finishes for high-spec applications.
Stainless steel ball blasting delivers a robust, uniform matte finish while maintaining the integrity of the base material—ideal for products that require durability and a clean, technical appearance.
Glass bead blasting provides a smoother, more refined finish, suitable for parts where a gentler surface treatment is needed without compromising cleanliness or functionality.
Both blasting methods are performed in-house under controlled conditions.
Pickling
We provide in-house pickling as part of our comprehensive surface treatment services, ensuring that stainless steel parts meet the strict cleanliness, corrosion resistance, and compliance standards required in life science, pharmaceutical, food, and other high-demand industries.
Pickling is a chemical cleaning process that removes oxidation, welding discoloration, and surface contaminants from stainless steel. This restores the material’s passive layer, enhancing its corrosion resistance and preparing it for further processing or cleanroom environments.
Our pickling process is carefully controlled to ensure consistent results without compromising material integrity. It can be applied to both individual components and welded assemblies, helping to maintain the high-quality standards
Electropolishing
We offer in-house electropolishing to meet the highest standards of surface finish, cleanliness, and corrosion resistance required by the life science, pharmaceutical, food, and other high-purity industries.
Electropolishing of stainless steel is an electrolytic process, a galvanic method through which the microstructure of the surface is modified.
Material is removed more from the peaks of the surface structure and slightly less from the valleys. As a result, the surface becomes smoother and, with increased removal, also shinier. Unlike mechanical grinding and polishing, the surface does not develop pores or inclusions but instead becomes homogeneous and aseptic.
Our dedicated electropolishing area is designed for precision and process control, ensuring consistent, repeatable results. We can achieve surface finishes down to Ra 0.2 µm, supporting applications where sterility and surface integrity are critical.
Passivation
As part of our complete surface treatment offering, Texor performs passivation to enhance the corrosion resistance and cleanliness of stainless-steel products.
Passivation of stainless steel increases the corrosion resistance of the treated material. By using a corrosive medium, a thin protective oxide layer is formed.
This oxide layer consists primarily of chromium oxide, which is created from the chromium in the stainless steel.
As a result, the surface becomes less reactive and therefore more resistant to corrosion.
Our passivation process is carried out in-house under strictly monitored conditions, often following pickling or electropolishing, as a final step to ensure each part is clean, chemically stable, and ready for use in validated environments.
