The impregnation process to seal porous castings and other materials can be carried out using several methods, a few of which are listed below.

Porosity sealing is critical when it comes to the use of castings, specifically in industries where structural integrity and performance are paramount. ISL boasts state of the art in-house twin impregnation process lines, which allows us to offer a porosity sealing uptime of 100%.

For over 50 years, we have been offering expert casting impregnation services specialising in vacuum impregnation.

Through our porosity sealing services, ISL can help you become more environmentally friendly, preventing you from needing to waste porous or leaking castings.

Internal Pressure Impregnation Process

Large castings occasionally outsize our conventional vacuum process lines.  In these cases, we are usually able to fill the casting with suitable resin and apply air hydraulic pressure to force the resin into the porosity.
