Injection channel for use in manufacture of micro-molded portion, has feed channel having injection point having an axle formed such that the injection point is directly coupled to downstream direction of feed channel in spraying direction

摘要

The injection channel (1) comprises a feed channel (2) having a feed axis (20), and an injection point (3) having an axle (30) which is formed such that the injection point is directly connected to the downstream direction of feed channel along the spraying direction (S). The feed axis is formed opposite to the axle, at an angle (alpha ) ranging between 20[deg] and 75[deg] . The average diameter (D3) of injection point is set between 0.1 mm and 1.0 mm. Independent claims are included for the following: (1) manufacturing method of micro-injection molded portion; and (2) micro-injection molded portion.
