About this title

Synopsis

Today, most molders, including many mold makers, specialize in certain areas. There are specialists for thin wall molding, screw caps, large beverage container crates, pre-forms for PET bottles, small gears, and many others. But, regardless of the size and type of the product to be injection molded, whether small or large, with single or multiple cavities, or who designs or builds the mold, the basic mold design principles are always the same. These basic design principles for good mold design are the focus of Understanding Injection Mold Design. The designer will not find elaborate drawings of existing molds, but instead he or she will learn about the many factors that must be considered when successfully designing a mold. 'I undertook to write this book essentially to explain what is really important in the design of an injection mold, so that a good mold, best suitable for the application, can be created even if there is no precedent. It is meant to be used to guide the designer to think, and to frequently ask, why, where, when, how, etc., when considering the many possible choices before settling on a final concept.' -from author Herbert Rees.
