TD finishing are experts in Dip and Spray Pretreatment systems. Some examples of recent projects include, Aluminium Pretreatment and powder coating to meet the Qualicoat standard for architectural aluminium. These Pretreatment systems consist of a 7-stage dip-tank Pretreatment plant incorporating chrome free chemical technology.
Pretreatment and Powder Coating Plants
We are also highly experienced with more general domestic Pretreatment and powder coating plants which have been installed for a wide variety of multi-metal processes, including: the high-performance eco-friendly silane and oxsilan chemicals.
These types of processes give high salt-spray performance approaching than given by traditional zinc phosphates and exceeding that from general industrial iron phosphates.
Fully-Welded Stainless-steel Housing Modules
All our Spray pre-treatment systems are manufactured with fully-welded stainless-steel housing modules for quick assembly on site with sealed bolted joints.
Easily Adjustable Spray Nozzle Assemblies
The Process tanks for each stage recirculate the liquid with a centrifugal pumping system. The pumps feed from stainless-steel pipe work to internally mounted CPVC standpipes within each stage, each standpipe has quick release couplers and easily adjustable spray nozzle assemblies.
Allowing for easy maintenance of the system and quick replacement where required. For heated stages the tanks are fitted with a highly efficient tube-firing gas burner or chemical-resistant submersible electric elements where appropriate.
Longevity and Hassle-Free Production
Entry and exit extract fans, maintenance walkways & access doors, internal lighting and twin-pump mesh filters are always incorporated into the standard design. The benefits of which include; minimal mist encroaching in to the factory space, allowing easy & safe access in to the plant, as well as protecting the pump from unwanted contaminants: ensuring longevity and hassle-free production.
TD can supply any Conveyorised spray, as well as auto & manual dip Pretreatment. Including among others; Combined degrease phosphate, zinc phosphate and chrome free systems.
