摘要

The molding tool (15) comprises a set of recesses (23a, 23b) for receiving temperature influence medium, where the medium is latent storage medium, and the closed recess is in the form of a storage chamber. The recess is arranged in a wall portion in a cavity which serves to form a plastic part. A cooling passage (22) is arranged on a side facing away from the cavity, and in operative connection with the recess. The tool further comprises two mould halves (16, 17) that are arranged in the recesses that has different volume or different form. The molding tool (15) comprises a set of recesses (23a, 23b) for receiving temperature influence medium, where the medium is latent storage medium, and the closed recess is in the form of a storage chamber. The latent storage medium is a salt optionally added with an additive. The recess is arranged in a wall portion in a cavity which serves to form a plastic part. A cooling passage (22) is arranged on a side facing away from the cavity, and in operative connection with the recess. The tool further comprises two mould halves (16, 17) that are arranged in the recesses that has different volume or different form. An independent claim is included for a method for manufacturing a plastic part.
