Impregnation

Impregnation is a vacuum and pressure process applied to all ferrous and non-ferrous metals. We can also impregnate brass, mild steel, plastic, and sinter parts. We can also impregnate parts that are machined, painted, anodised, alocromed, or cast.

Impregnation seals micro porosity within casting walls to ensure the casting does not leak air or fluids under pressure. Impregnation is also used to ensure there are no trapped gases within the castings prior to painting or other surface treatments.

We use a vacuum pressure process with sealant PC504/66, and a rotating, water cascade process with recyclable sealant.

We can process parts weighing up to 2 tonne and with a diameter of approximately 1300mm
