New finishing system plant for Swallow Architectural Aluminium Limited. 

The new Finishing system plant is required because Swallow Architectural have moved into a new purpose built factory in Elland near Halifax. The company had outgrown their existing finishing systems factory in Sowerby Bridge and needed to increase output. The only answer was to move to new bigger site and install new dip pretreatment and powder coating facility to handle to increase in demand.  

After many months of investigation into the best available process and equipment on the market, TD Finishing Ltd and Gema were chosen as the preferred suppliers to install the finishing plant. The demands of clients quality standards were foremost in the mind of managing Director Andrew Swallow and it was decided that the new facility should incorporate the latest chrome free pretreatment technology.

With this in mind, TD Finishing worked together with Chemetall Ltd, part of the BASF group, to design a system that would be capable of meeting the ‘Qualicoat’ standard. A seven stage dip pretreatment was installed consisting of:

Products are preloaded in baskets at the load end of the pretreatment and then processed through the dip tank via a manually operated crane system. After pretreament, the work is loaded onto the powder coating line for the automatic application of the powder. 

  • Stage1  Alkali Cleaner
  • Stage 2 Main water rinse
  • Stage 3 Acid etch
  • Stage4 Mains water rinse
  • Stage 5 Demin water rinse
  • Stage 6 Chrome free
  • Stage 7 Demin
  • Stage 8 Drying oven

The powder coating line consists of an Automatic Gema fast colour change booth system, semi-automatic monorail conveyor system and a high efficiency powder curing oven. Products up to 7.2m in length can be powder coated with a load capacity of 500kg.  

A full water recycling system was incorporated into the design of the finishing plant in order to maximise water usage and minimise water discharge.
