The conversion of existing electroplating installations to process technologies involving the lowest possible consumption of chemicals has previously been regarded as highly problematic.
The main point of conflict has the division of functions in cooperation between electroplating companies and chemical suppliers (electroplating specialists). To date, the cost of services provided by these specialised operators has been included as a proportional element of the cost of chemicals themselves. Consequently, any reduction in the use of chemicals, for the purposes of the conservation of resources, would make unwanted inroads into the turnover of these operators.
Under these conditions, new model systems for cooperation with electroplating companies have been developed and tested in practice under the direction of a specialised operator.
A set of internet-compatible and graphically structured guidelines has been produced which incorporates three models and specific decision-making support features:
- The first model, which applies the strict separation of the cost of services from the cost of chemicals, has met with little approval, given that electroplating companies regret the loss of services provided as a courtesy by specialised operators.
- Under the second model, specific process costs for each installation have been determined, and a price based upon characteristic values has been agreed per unit of electricity or per square meter of surface area treated. Although this cooperation requires a high degree of trust, it has proved to be highly satisfactory for both parties.
- Under the third model, “Chemical Management”, full chemical and technical responsibility for a given installation has been assigned to the specialised operator. A precondition for this arrangement was the establishment of comprehensive contractual conditions. The separate consideration of in-house electroplating facilities in companies which have other priorities has proved to be useful.
- A guideline was created as an interactive file (CD-ROM or internet), allowing an intuitive use and – through its hierarchically organised levels- offering an easy-to-use survey as well as multiply continuing contents and numerous linked documents.
