GEOMET® Surface Treatment Process

Environmentally Friendly Chromium-Free GEOMET® Surface Treatment Process

  • GEOMET® coating is developed by the esteemed NOF METAL COATINGS GROUP is an environmentally conscious, water-based, completely chromium-free coating and aligns with RoHS and REACH specifications, adhering to international environmental protection standards. 

    GEOMET® offers exceptional features, including salt spray and cyclic corrosion resistance, high heat and corrosion resistance, and prevention of galvanic corrosion with aluminum. Its superior coating adhesion performance, coupled with freedom from hydrogen embrittlement concerns, further enhances its appeal. Additionally, GEOMET® allows for the application of additional coatings, making it a versatile and reliable surface treatment solution.

    WKPT has embraced the environmentally friendly chromium-free GEOMET® surface treatment process, this advanced technology is based on the DACROTIZED® anti-rust coating, perfected through three decades of practical application.

  • Metal Surface Treatment Service - Elevating Performance with Environmentally Conscious Solutions by WKPT

    World Known Precision Industry Co., Ltd. (WKPT) is a comprehensive metalworking service provider, offering total metalworking solutions from design and material supply to expert production. One of our specialized services is metal surface treatment, where we employ cutting-edge technologies to enhance the performance and durability of metal machined parts.

  • Surface Treatment Technology for Aluminum Alloy Components

    For aluminum alloy machining components, WKPT employs anodizing and hard anodizing surface treatments. Anodizing controls the formation of an oxide layer on the aluminum surface, offering insulation, corrosion resistance, and wear resistance. Powder coating, known for its hardness and resistance to acids and wear, is also applied to aluminum alloy machined parts.
