Precision molding is a production process that uses more precise techniques and processes to make molds and parts than typical injection molding. If you want to ensure there are no air leaks between two molded parts or there are no visible seal gap lines, you need precision molding. The difference between a typical injection molded part and a precision molded part is the tolerance or range of acceptable dimensional variation: while most injection molded parts have tolerances of +/- .005", precision molded parts have tolerances of +/- .002" and +/- .001" (or less in some cases).   If your project requires high-precision parts that require precision molding, before you look for the proper manufacturer to produce them, precision molding supplier Shengqi tells you that the following 3 questions you need to figure out can save you a lot of time and money.   1. Are you sure which areas of the mold need precision? Because precision molding is more expensive than typical injecti...
