In response to high requirements from consumers for products in various fields, there is a trend focusing on light, thin, short, small and complex geometry. Furthermore, the time-to-market and short life cycle of product development require the use of scientific methods of rapid design. This can eliminate unnecessary trial and error approaches and result in development cost reduction. Therefore, adopting Taguchi techniques for experimentation can result in a reduction of the time and money required to conduct experiments. The factors that affect quality and stability can be identified and strengthening controls can be implemented in order to increase the yield rate of production.
Plastic injection molding professionals know when the mold design, mold construction and completion of post-production will take place. First, the procedures on the molding machine will be examined. The purpose of testing molding process stability is to determine if the product and mold design has poor appearance caused by defects. The size of the deviation is also calculated. Inappropriate molding conditions also will lead to poor results. Traditionally, molding conditions are usually based on the cumulative experience of the trial and error approach. When the products have problems or defects, the best way to solve them is by adjusting molding parameters and modifying the mold directly. But overcoming these solutions often requires the help of someone with a lot of experience. Without this, the problem will become even more serious.
