Metal Injection Molding (MIM) sits in a strange gap in manufacturing education — it's not quite casting, not quite powder metallurgy, not quite plastic injection molding, but borrows from all three. Most coverage online stops at "you mix metal powder with a binder and inject it like plastic," which leaves out the parts that actually matter: how the binder is debound without collapsing the green part, why sintering shrinkage is so dramatic (often 15-20%), and how engineers design around that predictable shrink.

This video promises to tackle the questions that the surface-level explainers skip. For anyone who's wondered why MIM is the go-to for small, complex stainless or tool-steel parts (think surgical instruments, firearm components, watch cases) but never made sense for large geometries, this is the kind of deep-dive that connects the process physics to the design constraints.

Everyday Metallurgy is one of the more substantive small channels in this space — at 2,340 subscribers it's the largest of today's candidates, but the content style leans toward genuine technical explanation rather than visual filler. The framing ("questions nobody has answered before") is mildly clickbaity, but the topic itself rewards the depth.
