At Eigen, we specialize in the high-precision surface treatment and plating of critical components across industries such as automotive, medical, electronics, and consumer devices. With decades of expertise in metal finishing and advanced coating technologies, we deliver engineered surfaces that enhance performance, extend durability, and meet the toughest environmental and aesthetic demands.
Surface treatment refers to a suite of post-processing techniques applied to material surfaces to enhance functionality, durability, and appearance. These processes may add material (e.g., coating, plating) or modify or remove material (e.g., polishing, passivation, heat treatment).
For metals and alloys, surface treatment is critical for corrosion resistance, wear performance, electrical conductivity, aesthetics, and adhesion of subsequent coatings.
Surface Treatment
Our surface treatment services cover a wide range of techniques and finishes, allowing us to tailor each project according to material type and performance requirements. We provide everything from pre-cleaning and activation to coating application, post-treatment, and inspection, ensuring a completely integrated process under one roof.
Eigen’s expertise spans across various plating technologies, including electroplating, electroless plating, and selective or multi-layer coatings. Our engineers carefully control bath composition, temperature, current density, and agitation to ensure consistent results across small or large production runs.
A typical surface treatment process at Eigen begins with component preparation and cleaning, followed by pretreatment or activation to remove oxides or contaminants. The components are then subjected to plating or coating, after which post-treatment processes such as passivation, sealing, or hydrogen embrittlement removal are applied.
Each stage is controlled using precise instrumentation and monitored through digital process tracking. Our in-house testing laboratory performs thickness measurements, adhesion tests, corrosion resistance checks, and microscopic evaluations to ensure consistency and reliability. Every batch is verified to meet ISO and IATF quality standards before dispatch.
Our goal is to be your partner for the entire manufacturing process, from custom design to high-quality finishing. Contact us today to see how we can help find your next manufacturing engineering solution.
Choosing Eigen means choosing a partner with deep experience in both material science and precision manufacturing. Our integrated facilities eliminate the need for third-party processing, allowing us to control every aspect of surface quality and consistency. We also prioritize sustainability — using eco-friendly processes, lead-free coatings, and advanced filtration systems to minimize environmental impact.
Our engineers collaborate closely with clients during the design phase to ensure that the chosen surface treatment aligns perfectly with the intended application, operating environment, and appearance requirements. This partnership-driven approach allows us to deliver components that perform flawlessly from the first prototype to full-scale production.
