Shainin's Varible Search DOE is one of practical experimental designs which is simply used in industry fields. The less numbers of experiments and basic calculation are the advantage over the classical DOE. In this work, Shainin's method is used to study factors effecting displacement of plastic work-piece in Injection model process. The implementation steps of experiments are provided in detail. After 22 experiments were carried out, it is found that Packing time (E), Cooling time (G) and interaction of EG are significant factors. The fraction factorial, 2<sup>7-3</sup>, is also employed as a comparison to Shainin's method. The results of Shainin's method in-line with those of fractional factorial. It imply the usefulness of this practical DOE.
