AutoSeal® Moulds product overview 

The built-in felt expands during the preheating phase of welding, creating a tight seal between the mould and rail. This completely removes the need for luting with paste or sand, whilst preventing welding leaks. They are the world’s first self-sealing moulds and bring numerous benefits including faster welding speeds, enhanced welder ergonomics, increased reliability, and reduced waste. 

• This new technology has been developed by our welding experts and is compatible with Vignol and Grooved rail. 

• AutoSeal® moulds are recommended for the most demanding rail networks, meeting the needs of short possession times and high safety standards.
