Mould

Patent No. EP2857166 (titled "Mould") was filed by Thorsten on Sep 18, 2014. The application was issued on May 27, 2020.

Patent Summary

A two- or multipart mold for producing molded bodies from expanded thermoplastic particles comprises a mold cavity (3) with a filling opening (4) and one or more external openings (5, 5', 5'', 5'''). To vent the cavity, the walls (11) feature a surface structure of channels (10, 10') with widths between >0.01 mm and <2.5 mm. These channels, and the distances (12) between them, lead directly or indirectly to the filling opening or external openings. The channels are defined as the spaces between a plurality of irregularly distributed protrusions on the cavity walls, which are created via laser radiation. This configuration facilitates the escape of air and steam during expansion to produce a largely non-porous surface on the resulting molded body (9).
