Wet casting mold for producing concrete products, has lower part and tub that is formed on lower part, where tub has base and circulating edge and is made of flexible material

摘要

The wet casting mold has a lower part (4) and a tub (5) that is formed on the lower part. The tub has a base (5a) and a circulating edge (5b). The tub is made of flexible material (M1). The lower part is made of another flexible material (M2). The latter flexible material is less flexible and is harder than the former flexible material. The former material is polyurethane, which is produced by the mixture of polyol and isocyanate. An independent claim is also included for a method for manufacturing a wet casting mold in counter part.
