LEGO Effect: Injection Molding Basics and Common Design Mistakes | Manufacturing Methods #4

Описание: Take a LEGO part in your hand. It feels the same every time: the fit, the click sound, the gap, the surface. That repeatable quality is not a coincidence. It is the discipline of injection molding. But there is a price: a small design mistake does not stay on one part. It gets replicated thousands of times through the mold.

In this episode, we build a clear, practical framework around injection molding:

Process logic: filling, packing, cooling

When to choose it: volume, function, integration

Key limits: shrinkage, ejection, undercuts

Typical mistakes: non-uniform walls, rib design, missing radii

A quick DFM checklist: 5 practical rules

In the advanced training, we go deeper into: gate location, cooling balance, material selection, mold flow simulation, tolerance analysis, and mold design.
