Without a good pre-treatment there is no high-quality galvanising process. Depending on the quality requirements of your products and the materials used, you can choose for a wet chemical pre-treatment with one or multiple pickling and cascade rinsing baths in a dipping bath line.

Indufinish offers a wide range of products, both plastic and stainless-steel baths to spray tunnels for the UF-rinsing’s. We have the expertise to realise the perfect solution for your situation. Sophisticated design of the various spray phases guarantees an optimal pre-treated product in steel, aluminium and galvanised steel. As standard, our spray pumps in the pre-treatment installations are fitted with frequency converters in order to optimise energy consumption and to be able to set the correct spray pressure. This prevents unnecessary energy loss through throttling valves. Needless to say, that we are in constant contact with the chemical suppliers, in order to keep up to date with the latest process developments.

Precise temperature control in both galvanic, pre-treatment and KTL/ATL baths is very important for proper process reliability and film thickness composition. In addition to external heat exchangers for heating a bath, you can also choose for heat exchangers in the bath, for strong chemical processes made of plastic. Both can be supplied with central heating water or electrically. Cooling systems are carefully designed by us, where good fluid exchange and good cooling is achieved through heat exchangers and an innovative piping system with eductors.

Indufinish designs drying and curing ovens with an operating temperature between 35 and 220 °C. The drying and polymerisation processes of water, powder coatings and electrophoresis paints fit within this temperature range. Materials such as steel and non-ferrous metals are heated evenly during the process until the coating has dried or hardened. Which heating system we use, depends on the type of coating and the available energy sources (gas/electricity). In all concepts (air circulation, IR or so-called dark radiation ovens) we carefully study the possibility of heat recovery and, where possible, we apply it. Uniform heating in combination with active air locks or automatic doors in the product entrance and exit openings, are key concepts in the drying and curing process. They have a major impact on your energy consumption. We guarantee the engineering of air distribution and air locks in such a way that your energy consumption is kept to a minimum.
