Hot Dip Tinning

Tin electroplating , or tin plating, is used for several different reasons, for example on Copper or Aluminium electrical conductors, it improves conductivity, and is used especially on contact points, to improve corrosion resistance. It is also used for food packaging, and articles in contact with food, RFI shielding, and heat exchangers.

We vat tin electroplate large quantities of both copper busbar, and components (up to 5 metre long), and Aluminium up to 3 metres. We also barrel plate small components in a fully automated plant,such as electrical cable crimps and connectors, and vehicle battery terminals. On this plant also offer nickel as an undercoat for brass components which require tin plating.

Hot Dip Pure Tinning

This is used for articles in contact with food, such as frying baskets, cake cooling trays, whisks, cast iron & steel meat mincers (mainly for butchers, and meat processing plants), pie  tins for artisan bakeries, pie hoops for pork pie manufacturers, and meat hooks, and of course copper cookware. Years ago we tinned many thousands of milk churns for the dairy industry, and Cadbury’s, we also used to tin baking dishes, and scale pans. We also recently pure tinned a few thousand tin tacks for the V&A museum for their picture restoration workshop.

Hot Dip Tin/Lead or Solder Dipping

This is used for components that need to be soldered, or to improve corrosion protection on mainly brass and copper components, for the electrical and heat exchange industries. We recently hot solder dipped all the radiator cores for a new Isle Of Wight passenger Hovercraft, as samples that were made for testing went to over 3000 hours saltspray testing, but after 125 days the customer wanted to use the salt spray cabinet for another test!  We have tinned radiator cores for Spitfire and Mosquito aircraft in the last few years.  We have also solder dipped many fuel tanks for fighting vehicles over the years. Lately due to the demise of the availability solder coated steel sheets, we are solder dipping  fuel tanks for veteran & classic cars in component form, so they can be assembled and soldered together, we have done tanks for Bugatti, Bentley, Crossley, Jaguar, and Rolls Royce cars, and many others.
