When it comes to injection molding, the pre-production stage can be challenging to those who are unfamiliar with the part and tool design process. Plastics Plus has decided to create a simple post on the different ins-and-outs of tool design that explains what goes into designing a mold and how your part design is affected. What good tool design does is save time and money by making sure your part comes out of production to the specifications you desired; while exemplifying good quality, strength and usability.
