  • Chrome plating: Chrome plating is a process in which a thin layer of chrome is applied to the surface of a metal object. This treatment is ideal for improving corrosion resistance and wear resistance, while also providing a glossy finish.
  • Nickelization: Nickel plating involves coating metal parts with a layer of nickel to improve their resistance to corrosion. It results in a hard, abrasion-resistant surface with a clear or matte finish.
  • Chemical Blacks: Chemical blackening is a process used to form a black conversion layer on steel, resulting in increased corrosion resistance and reduced light reflection.
  • Epoxying: Epoxying involves applying a thin layer of epoxy resin, which provides a strong, durable and chemically resistant coating. This treatment is perfect for protecting surfaces from corrosion and wear.
  • Coating: Coating is a general term for applying a protective or decorative layer to a surface. Methods and materials vary, depending on the desired result.
  • Galvanizing: The galvanizing process protects metals by coating them with a layer of zinc, which helps prevent corrosion.
  • Pickling and Passivation: Pickling is the process of removing impurities such as rust from metal surfaces. Passivation is a method used to protect the metal from further corrosion.
  • Electrolytic Polishing: Electropolishing is a process in which metal is polished in an electrolytic solution, resulting in a smooth and shiny surface.
  • Gilding: Gilding involves applying a thin layer of gold to an object, often for decorative purposes or to prevent corrosion.
  • Redeem: Like gilding, silver plating means applying a thin layer of silver to an object for both aesthetic and functional benefits.
  • Cleanroom Packaging: For products that need to be packaged under sterile conditions, TEVEMA offers cleanroom packaging. This ensures safe and clean packaging, free of contaminants.

GSA Grade 2 & grade 4 springs

Even minute contaminants can cause major problems in precision machinery, making surface cleanliness a top priority in precision engineering and high-tech industries. Tevema is responding by supplying parts such as compression springs, leaf springs and tension springs already cleaned, simplifying the assembly process of these cleaned parts. This precise cleanliness is not only essential for the production process in industries such as semiconductor, aerospace, etc., but is also required to support the electronics and medical sectors. Tevema’s carefully cleaned springs are indispensable for meeting strict GSA Grade 2 & 4 standards for finished products.
