FIELD: process engineering.SUBSTANCE: invention relates to production of containers from thermoplastics. In compliance with this method, extruded plastic sleeve is fed into die with moving shaped parts in position to open said die. Die shaped parts that make transition between container main part and container bottom are closed while container bottom is welded. Sleeve is expanded by pressure gradient applied thereto. Shaped parts are moved in die opening position to withdraw shaped container from the die. Container bottom is shaped to pot extending container main part in axial direction. Said main part in turned inside container to make bottom lug extending inside container main part.EFFECT: higher quality of container.7 cl, 10 dwg |
