摘要

Method for manufacturing a molded article having a core, a device for the manufacture of a molded article having a core, an article molded and household articles molded.The present invention relates to the manufacture of an efficient, a molded article having a core and, at the same time, from a molding material such as a granule powder.For this purpose, a method for the manufacture of molded article having a core was developed. The method uses a device for compression molding.Which comprises a matrix of molding, members of the upper and lower puncture, where at least the state superior puncture, preferably both states of the upper and lower puncture.They have a double construction consisting of a state and a member of the central puncture puncture around the external periphery of the external state of the central puncture.Both the state and the State Central puncture puncture outside being able to play movement of displacement and compression operations.This method includes steps of feeding material separated from the molding to the core and molding material for the outer layer.A step of compression molding the molding material for the core and / or material moulding for the outer layer.And a step of compression molding the end of the article and a molded core. The invention also provides a rotary machine for compression molding, used for execution of the method.The invention also provides several features to a molded article having a core manufactured by the manufacturing method mentioned above.The core may include a large amount of microcapsules that are molds, incomplete, or a plurality of cores.
