Ⅱ Points for reducing the defective rate in product design

This section introduces the points at the product design stage for reducing the defective rate regarding medical plastic molding. We will explain with actual examples that the points to be careful in product design necessary to suppress the occurrence of defective products due to welds, voids, short shots, etc. that are likely to occur in medical plastic injection molded products. Please use them as useful materials for the development and design of plastic injection molded products.
