This eBook will describe how to control injection molding tolerances and ensure high quality through DFM (design for manufacturing) principles, material selection, tool design, and process control.

The vast majority of plastic products are manufactured using injection molding. This is primarily due to the process’s high production rates and very low unit cost. As with any manufactured assembly, the tolerances are of critical importance. If they are incorrectly specified or controlled, the final parts will not fit together during assembly. These types of errors are especially problematic since the upfront cost of the mold is so significant.

Learn how to optimize injection molding tolerances and avoid making costly errors by following the principles outlined in this free eBook.
