Wire Phosphating

The phosphate coating of steel wire is very important for the drawing process and the further proce-

ssing of the wire. We supply single and multi-wire plants based on an innovative phosphating proce-

dure.

In this innovative process of phosphating the wire is plated electrolytically with Calcium-Phosphate.

It saves energy and operating costs, provides an easy handling and has many advantages compared

to the previous, classic method of zinc phosphating in immersions.

Our phosphating-process is characterized by the following points:

— It's free of heavy-metals

— The discharge is sludge-free

— It runs at room temperature, that means the plant is ready for operation in minutes, because there

    are no pre-heating phases

— The coating thickness can be set precisely by adjusting the current

— Top performance

— In order to control each single wire individually the multi-wire plant consists of two separate treat-

    ment baths with the appropriate pumps

— Bonding occurs through the use of insoluble anodes in liquid

The main benefits are:

— In one-and-the-same plant a variety of flow-rates are possible

— For each individual wire the coating thickness can be set precisely

— Each chamber has its own pump to prevent any pickling effect during downtimes

— No sparking

— No loss of current as there are separate circuits for each wire

— The plant is easy to use

— Reduced energy and operating costs
