Electroless Nickel Plating services

The decisive advantage of chemical nickel is the completely uniform layer thickness distribution with low layer thickness tolerances, which makes it possible to coat even complexly shaped components with cavities or holes, covering every contour.

Part surface treatment

CNC Machined Parts Electroless Nickel

  • Electroless nickel deposition is a process for the co-deposition of nickel-phosphorus alloys without the need for an applied electric current.
  • Instead of depositing ions from an applied current, this electroless nickel process chemically reduces nickel ions to the metal substrate in an electroless nickel solution. Therefore, the electroless nickel layer does not suffer from many of the problems associated with conventional electrolytic nickel, such as edge build-up and coating non-uniformity. The electroless nickel layer is very uniform, resistant to corrosion and corrosion, and has excellent lubricating properties.

We have high standards for Part surface treatment

We manufacture your custom parts according to strict manufacturing standards and ensure all parts and processes adhere to the Xavier Standard. A thorough verification of these requirements is included in our inspection report that we ship with every order.

  • Standard 1
    PO consistent

    We ensure that every part after machining is as specified in the PO as customer requirements.

  • Standard 2
    Quality check

    Prior to MP shipment to ensure that each part meets order specifications and Xavier standards.

  • Standard 3
    Require consistent

    Ensure conformance of parts and any required documentation prior to dispatching the order.

We did a quick build test of all versions and the looks, performance specs and functionality were good, and they worked just as well, as always. Delivery date no problem!
