Abstract
A method of setting molding conditions for an injection molding machine 1 using a mold 2 whose specifications data are unclear included three setting processes. In the first setting process A, by inputting known data into controller 3, the molding conditions based on a data base prepared in advance and said input known data are set. In the second setting process B, injection molding is performed according to prescribed molding conditions pre-selected concerning injection pressure P, injection speed V and the injection start position of screw 4, and then, based on the product just molded, injection pressure P is altered, to set said altered injection pressure P, injection speed V and proper pre-feed measurement value Md as molding conditions. In the third setting process C, injection molding is performed according to molding conditions obtained from said second setting process B, and subsequently, taking into account the findings from the product just molded, said molding conditions are adjusted. In this manner, even an unskilled operator is allowed to undertake setting molding conditions reliably and with great ease for an injection molding machine loaded with a set of molds whose specifications data are unclear.
