Injection molding is one of the most common manufacturing methods to produce thin-wall engineered parts. Development of molds that produce high quality parts is a talent that develops with experience. Due to the time and effort required to develop a good set of tooling, it is not unusual for manufacturers to seek out injection molding machines that will be compatible with their molds, rather than trying to redesign molds to work on specific machines. As designers of injection molded products you are probably well aware of design best practice. What you may not appreciate is the important contribution a well designed mould tool can make to the new product development process. The wrong decisions taken at the critical early stage of a project will add cost and time to mould tool design, manufacture and maintenance, put pressure on product launch dates, and, of course, adversely affect product manufacture and in-use performance.
