HTA ltd have recently installed a brand-new powder coating line, consisting of A silane based spray pre-treatment plant, RO Water system, drying oven, curing oven and a heavy-duty Conveyor, with a flight bar load rating of 200 kg. As well as td finishing’s latest Industrial PC control system. The client in this case also chose Gema to work alongside td finishing to provide their state-of-the-art automated online powder-booth.
HTA ltd are one of the largest subcontract suppliers of laser cut parts, sheet metal components and fabricated assemblies. Their continued investment in manufacturing technology, alongside robust process and control systems enables them to ensure the business can support all the needs of their customers. Their customers form a broad range of industries including; automotive, defence, oil & gas, rail, earth moving machinery, power generation, electronics & switchgear and transportation.
For sheet metal processing the new td finishing powder coating plant can accept product up to 1.5m high x 0.8m wide x 3.6m long and runs at an average process speed of 1.5m/min.
The control system utilises the latest td finishing Industrial PC, which you can read more about here in our smart factory article.
As at HTA, td finishing installed several large-scale silane-based pre-treatment systems in 2018. Most of which were completely new lines, a good sign for British manufacturing. Whilst others replaced existing phosphate-based systems.
The additional benefits of a silane based td facility are numerous and include the following;
More environmentally friendly
Silane based pre-treatments require no heating in the treatment stage, reducing gas & water consumption, running costs and maintenance.
Tighter restrictions and controls on traditional chemicals. Such as phosphating and chromating, have made the more sustainable and environmentally friendly chemicals very appealing.
Better corrosion resistance
Not only are the silane pre-treatments more eco-friendly, they vastly improve the corrosion resistance of various different materials. Silane products in terms of quality can be used as a direct replacement for zinc phosphating and chromating processes.
Industrial change towards multi-material design is also becoming vastly important. The trend towards lower weight, more stylish design along with increased safety, means multi-metal component manufacturing is on the increase. Silane based pre-treatments allow for the processing and surface treatment of all common metals and alloys, in any combination on a single line. Reducing capital plant investment as well as long-term running costs.
Reduced Lifetime Costs
A Silane based solution means the new chemical process for our customers is free from heavy metals and phosphates. This removes the risk of an expensive accidental discharge of these materials into inland or coastal waters. The Silane process also results in a 95% reduction of sludge. Reducing the requirement for effluent treatment capabilities, as well as mechanical and chemical cleaning intervention during the life-time of the equipment.
As legislation and research progress the likelihood of a customer changing their requirements or specifications increases. Driven by the automotive industry, there has been a continuous movement in general industry towards increased corrosion resistance, with increased salt spray requirements. td finishing pre-treatment and finishing equipment is highly adaptable and can be future proofed for a variety of different chemical regimes. Should the requirement to change arise in the future.
