Точка А указанной концевой стенки имеет определенное значение удельной энтальпии остаточного плавления. Удельная энтальпия остаточного плавления равна разнице между удельной энтальпией полного плавления и удельной энтальпией кристаллизации части аморфной фазы, которая кристаллизуется при ее нагревании. Указанные величины измеримы с помощью анализа методом дифференциальной сканирующей калориметрии (ДСК). При этом по меньшей мере одна точка В, F, L, О боковой стенки имеет другое значение удельной энтальпии остаточного плавления, которое больше, чем указанное значение.

ДИНАМИЧЕСКАЯ ФОРМОВКА: ФОРМА И ПРОЦЕСС ФОРМОВКИ

Заявленная группа изобретений для динамической формовки включает производственный процесс и техническое оснащение. Производственный процесс состоит из двух и более этапов (отдельных операций), протекающих одновременно. Станок формовки выдуванием и станок формовки впрыскиванием могут работать с одной и той же формой одновременно. Динамическая формовка предполагает разделение формы на несколько частей. Это обеспечивает движение отдельных частей формы и извлечение из нее продукта, а также делает возможным поэтапное протекание производственного процесса. Например, в целях сдвигов, термодинамики, температурных требований к качеству продукта, а также сниженной стоимости дизайна формы, две или более операции могут происходить с небольшим разрывом одна за другой. Динамическая форма применяется для работы с металлами. Также она включает гидроформовку, пробивание отверстий, ковку и т.д. Производственный процесс совместим со всеми известными промышленными операциями работы с металлами, пластмассой ...

Disclosed is a preform which comprises a functional filler blended into a resin comprising a poly(L-lactic acid) and which has an opening treated by heating. Also disclosed is a hollow molded article formed by the blow-moldin g of the preform. The preform is improved in the degree of crystallinity at the opening and has good heat resistance. Therefore, the preform is suitable for practical use.

PREFORM FOR PLASTIC CONTAINER WITH THIN BOTTOM

The invention relates to a new PET preform design that enables a more precise distribution of material in the bottle bottom and avoids the waste of material around the injection point. The thickness BWTmin of the wall at the center of the gate or tip (3) (injection point) is reduced to a minimum in order to avoid the waste of material around the injection point when the preform is blown. This is particular important for carbonated soft drink application since the reduced amount of amorphous material at the center of the gate (3) helps to reduce the risk of stress cracking on the bottle base. Furthermore a step (4) having thickness WTmax in the body wall thickness, in the region of the periphery of the base with WTmax > WT, allows enough material to be available for the proper blowing of the bottle bottom making the bottle more stable.

Apparatus for forming a blown thermoplastic article

A method and apparatus are disclosed for forming blown thermoplastic articles in which an extrusion head extrudes an essentially tubular parison of thermoplastic material. Sections of a preform mold are then closed around the parison, the sections having a preform cavity with a configuration such that one end of the parison is open after closing and the other end is enclosed. A core pin is next inserted into the open end of the parison and is utilized to compression mold the parison to form a preform. Heat is transferred from the parison through the inner and outer walls of the preform between the mold cavity and core pin during the compression molding step in order to thermally condition the preform and bring the temperature within the desired range. The sections of the preform mold are then opened and the preform is enclosed within sections of blow molds within a blow mold cavity. The preform is next expanded to the shape of the blow mold cavity. This process may be continuously repeated by means of multifunction mold halves.
