Gold: 7 Plastic Injection Mold Tooling Mistakes That Can Cost You Thousands (Ep. 48 Revisited) [Podcast Ep. 351]

Plastic injection mold tooling mistakes can cost hardware companies thousands of dollars, delay production, and even result in losing access to their own molds.

In this Gold episode of China Manufacturing Decoded (Ep. 351), we revisit a conversation between Sofeast’s Renaud Anjoran and experienced product designer Andy Bartlett about 7 common pitfalls in plastic injection mold tooling development, approval, and maintenance.

A validated prototype is only the beginning. Before investing in production tooling, companies need to understand DFM reviews, mold design, tooling trials, supplier selection, ownership agreements, and ongoing maintenance.
