material processing

Hygroscopic materials such as Rohacell PMI foam are oven dried before machining as part of the manufacturing process to remove any moisture undertaken during transport and storage periods.

Particularly in the case of Rohacell PMI foams and similar specification materials used in closed mould laminating , drying is a critical procedure in the manufacturing process. Material drying ensures dimensional stability and the prevention of ‘steaming’ during the cure cycle which would lead to lamination failure.

Parts manufactured from dried material are subsequently stored in DIN53122 vapour barrier foil packaging preventing further moisture ingress ready for despatch.
