Welders And Sheet Metal Engineers
Powered paint is used rather than liquid paint. It has almost the same consistency as flour. As the powder particles pass through the tip of the spray gun they are charged and the powder is attracted electrostatically to earthed parts. It was once thought only metals or alloys could be painted in this way but with our special powder coating gun, techniques and procedures. We can powder coat glass, ceramics and MDF ( But this take a lot of time and preperation)
The process cannot be used on items made from plastic, nylon or fibreglass. The powder will not attract or adhere to fillers either. Once the powder has been applied it adheres to the surface in much the same way as rubbing a balloon up and down on a fabric and then placing it on a wall. The part is then lifted together with its earthing hook and placed in a conveyor stoving oven.
Parts pass through the oven for a twenty-minute period at a temperature of 180C. At this heat the powder melts, bonds to the metal and forms an even coating. Once they are removed from the oven the parts are hung up to cool for twenty or thirty minutes before they are packed. When the hooks are removed a small “witness” mark is left where the metal-to-metal earthing contact has been made
Our powder coated finish is usually 60 microns deep. It is very tough when compared with wet sprayed finishes and will not crack, craze or chip easily.
All finished parts are inspected (prior to bubble-wrap packaging and despatch) to ensure our high quality standards are not compromised in any way. Whilst most of our work arrives via personal calls from customers. We do also accepts parts via carrier & post.
Parts can be returned via carrier, Delivery will be charged extra.
