One-piece article obtained by injection molding, with at least one injection point, said article comprising a main body (20), having a body volume defined by the space within a surface forming an outer envelope, and at least one hook (21), preferably a field of hooks, obtained from the same molding of the main body of the molded article, the hook or each hook having a stem of longitudinal axis and a catching part projecting laterally from the stem, characterized in that the volume of the hooks is substantially smaller than the volume of the body, i.e at least 100 times smaller, preferably at least 1000 times smaller, for example between 100 000 and 100 000 000 times smaller, than the volume of the body, and in that the width, or smallest transverse dimension, of the stems, measured transversely to the longitudinal axis, is smaller than the thickness of the main body, measured along the longitudinal axis of the stems.
摘要:
A feeding mold including a runner and a gate structure is provided. The runner is adapted to be filled with a liquid-like material. The gate structure includes a storage cavity, a running passage and a filling cavity. The storage cavity communicates with the runner and is adapted to store the liquid-like material filled by the runner. The running passage communicates with the storage cavity. The running passage is adapted to carry the liquid-like material from the storage cavity so as to evenly distribute the liquid-like material. The running passage has a protruding buffering cavity which is located between the storage cavity and the filling cavity and is adapted to change the velocity of the liquid-like material in the running passage, and lower the temperature of the liquid-like material flowed onto a surface of a workpiece.
