A prestigious domestic appliance manufacturer has just awarded TD Finishing a contract to provide their replacement powder coating facility. They have opted to replace their ageing phosphate pre-treatment line with a modern and more environmentally friendly Oxsilan pre-treatment system. Whilst updating their drying and powder curing ovens for better performing, more efficient TD Finishing ovens, with Fully modulating gas-and-air burners and negative air-seal system.
5-Stage Oxsilan Spray Pre-Treatment System
The 5-stage Oxsilan (conversion coating) spray pre-treatment system offer many advantages over traditional pre-treatment lines and can boast comparable quality to zinc-phosphating. The first advantage being the ambient bath temperature, offering lower gas consumption and running costs. Secondly; the treatment is free of hazardous metals (no heavy metal water treatment required) whilst simultaneously offering superior corrosion resistance on multi-metal components. It also requires no activation or passivation stage and has been proven in a wide variety of appliance and automotive applications giving up to 1,000 hours salt spray test.
Pre-Treatment Plant Experts
TD finishing are well versed in the requirements of the pretreatment plant equipment required to work with the chemistry for Oxsilan and a wide range of processes. Key factors including; spray times, extraction requirements, drain zones and Demin water supply are all extremely important when choosing a plant that will not only maximise efficiency but ensure the selected coatings work to their optimal performance, giving our clients peace of mind.
To further improve efficiency, in this instance TD Finishing will also install for the client an air-to-water heat recovery system. Which will supplement the fully modulating burner in the Stage-1 Alkali Degrease Cleaner with waste heat from the powder coating oven exhaust.
The system above will be delivered with a side mounted conveyor system to prevent contamination to the painted components. While a specially designed carrier will be supplied to ensure the products can be accurately located on to the line consistently and quickly, in a high production environment.
Once again working on this project with TD the client has chosen Gema to provide their new automated powder coating booth.
