Injection molding method

摘要

The invention relates to a method for producing footwear (10), comprising: (a) providing an upper (11); (b) providing a mold (21) and opening the mold (21); (c) inserting the top (11) into the open mold (21); (d) closing the mold (21); and (e) injecting a molten resin under pressure, (f) wherein, after the injection, a gap (22) filled with the resin between a side wall (25) of the mold (21) and an outer surface (17) of at least a first portion of the upper part (11), the gap (22) at a contact point (24) being essentially zero, the gap (22) gradually from the contact point (24) in at least a first region (39) of the shape ( 21) increases.
