CA 2276513

A device for stamping plastic material such as soap comprises a porous die (10) whereby release fluid (20) may be applied to a substrate stamping surface through the pores. Additionally the substrate stamping surface may be brought into communication with atmospheric pressure or with a source of reduced pressure to aid removal of air from the die during the stamping process. A process for stamping plastic material with a porous die is also disclosed.
