ABSTRACT:
A starting position of high speed injection is adjusted by an apparatus comprising a position detector which detects the stroke position of an injection plunger and a computer calculating a first position of the injection plunger at which a high speed injection instruction is given and a second position of the injection plunger at which the injection plunger actually reaches a desired speed. A data input device is provided for presetting in the computer the actual starting position of the injection machine, a theoretical value of a time lag between a starting instruction and an actual starting, and a predicted low injection speed. The computer calculates high speed injection starting speed based on the preset data.
