Use of ISO 20457 - Plastics Moulded Parts — Tolerances and ... - reddit

Hi all, I'm an engineer and I've been asked to detail a DWG with tolerances for a plastic part under development. My approach is to start with what the part needs to do, and set acceptable tolerances based on that. I am following Y14.5 in applying GD&T etc. I'm curious whether you all are familiar with and apply ISO 20457:2018.

Injection Molding Tolerances: Four Ways to Optimize Them

What are the typical tolerances for injection molded parts? Injection molds are made using CNC machining, which has high accuracy and precision. Typically, it is possible to achieve a tolerance of +/- 0.005 inches. It is also possible to achieve more restrictive tolerances using the method. However, this depends on the machine and team experience.

Rubber Part Tolerances | Dimensional Tolerances | Engineering Tolerances

Jul 30, 2021·The RMA Handbook lists four levels of engineering tolerances for molded rubber products. A1 – High Precision A2 – Precision A3 – Commercial A4 – Basic As a rule, higher-precision rubber products have higher material costs. They’re more expensive to mold because the design and machining requires a greater degree of precision.

For example, if DIN 16742 TG3 is the specified tolerance standard, and a “NW” (non-tool-specific) dimension has a nominal value of 1100, a tolerance of ±0.77 will be applied, based on the "1000" (“> 800 to 1000”) category for the TG3 group. (The ±0.77 tolerance would also be applied if TG1 or TG2 were specified.)
