Foleshill Metal Finishing in Coventry add to their electropaint capacity with a new dip pretreatment plant and electropaint system. The plant incorporates acid descaling for laser cut products, a unique space saving walking beam stoving oven arrangement. They also incorporated a zinc phosphate tank with agitation and filtration. The zinc phosphate tank consists of a collection tank, sludge transfer pump and filter press. td finishing offers the design and installation of bespoke finishing systems for clients in the UK, across Europe and the rest of the world.

 

Pretreatment Plant – The Capabilities 

The new system is capable of coating products up to, and including, 2000mm long x 1,500mm high x 1,000mm wide. It was split into three separate processes:

  1. Pretreatment plant with 14 separate dip processes
  2. Electrophoretic coating, which consisted of a further four stages, one e-coat and three UF rinses
  3. Stoving – The flight bar is then transferred to the oven by the transporter system. The walking beam mechanism indexes the products through the stoving oven for a minimum of 30 minutes.  

Included within the scope of supply for this system were cleaning tanks, pickling tanks and rinses. The system, where appropriate, utilises gas or electric heating, as well as lip extraction for high-temperature tanks. This helps to ensure a safe working environment for employees. The automated transporter system with PLC/HMI controls, transfers the workload flight bar from the pre-treatment line, onto the electrophoretic coating line. It will then deposit it into the stoving oven. 

 

Efficient and Environmentally Conscious

To improve the process and save water, the system was supplied with a new R.O unit for demineralized water, water counterflow and recycling system. As well as a pH correction system for overflow to drain.

All equipment is designed using the latest CAD technology, by our amazing team of in-house engineers. Their experience enables them to create up to date systems that meet clients demands, and all the current market requirements. This design experience is used for plant from basic batch equipment, to complete conveyorised systems incorporating HMI touch screen and PLC controls.
