We consider ‘Product Treatment’ as one of the most important requirements before considering any form of finishing, be it Plating, Powder Coating, Zinc rich primers, Electrocoating, Solvent or Waterbased top coats.

All pre-treatment plants are purpose built and are designed to comply with the client’s process requirements. The Process is specified by the Chemical Suppliers and structured to meet the Salt Spray requirements of the end user.

Design requirements therefore include specific process requirements such as:

  • Plant capacity and product size;
  • Number of process stages, tank temperatures and
  • circulating volumes/pressures;
  • Ventilation;
  • Demineralized Plant and storage/circulation;
  • Chemical dosing;
  • Effluent treatment to meet the latest environmental
  • requirements;
  • Related controls including SCADA.

There are various possible configurations to meet the production requirements, and often the space limitations that may exist. A further important factor include the variety/mix of material that require to be processed.

This is exciting since many ‘jobbing facilities’ would typically require to process Mild Steel/Galv. Steel/ Stainless Steel/and Aluminium through their facility. Bendet Engineering Services, in collaboration with associate companies have designed pre-treatment plants that can accommodate the vast metal treatment requirements.

Types of configurations include:

  • Continuous spray tunnels;
  • Indexing dip systems;
  • Combination of Spray/Dip Systems;
  • Batch type process with overhead gantry.

Our construction includes for state-of-the-art type construction in polypropylene material, but we are also able to provide cost effective construction in alternate materials when necessary.
