PRODUCTS FROM PLASTIC MATERIAL MANUFACTURING METHOD Russian patent published in 2018 - IPC B29C53/84 B29C57/00 B29C43/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the articles from plastic materials manufacturing method. In particular, this method relates to the manufacturing of containers caps with the tamper-proof tape having the inwardly flanged bead, at that, the bead is, in particular, configured to produce a mating member interacting with the container neck so that with the first container opening, to disconnect the container opening protection tape. Articles from a plastic material manufacturing method comprises the following stages: made of a plastic material article formation, wherein said molded article has at least a lower portion; formation, at said lower portion, of the easy tear-off portion separating the edge portion from the remaining lower portion, wherein said formation stage comprises the material removal stage; wherein the said material removal stage is carried out with respect to the said lower part plastic material at a removal temperature, which is higher than the ambient temperature, but below the upper limit value Tsup=Tα+10 °C, where Tα – is the said plastic material intermediate alpha transition temperature.

EFFECT: invention provides the articles of plastic material manufacturing method with the bead after molding part, facilitating production of the accurate and reliable required configuration of this bead part.
