摘要： Method of forming an article from a molten plastic composition including a polymer and a blowing agent. The method provides that during an injecting step (c) and a packing step (d), the injection pressure and the packing pressure, respectively, are maintained above a minimum pressure threshold in at least one second region of the cavity to maintain the physical blowing agent as a gas dissolved in the polymer so that substantially no gas bubbles are formed in the at least one second region, during a mould opening step (e), at least some of the molten plastic composition is exposed to an external pressure lower than a minimum pressure threshold to form in the article at least one first portion having expanded cellular foam formed from the plastic composition, and prior to the opening step (e), the plastic composition in the at least one second region of the cavity has been cooled so as to be fully solidified to form in the article at least one second portion having a substantially homogeneous, solid phase, unexpanded plastic composition.

摘要： Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.

摘要： A method of forming an article by controlling the thickness of a portion of the plastic composition which comprises a layer of molten plastic composition between opposite first and second solid skins, so that the thickness is constant with a very low tolerance of +/−0.5%, preferably +/−0.2%, when the portion is subsequently exposed to a reduced pressure to cause expansion of the layer of molten plastic composition to form a core layer of expanded cellular foam between the first and second solid skins, and by controlling the stretch of the first solid skin to be within the range of 0.5 to 3%, the expansion of the plastic composition can be highly uniformly controlled in the expanded wall parts.
