NMI evolved from deep experience in plastic cartridge manufacturing through PMT. After years of seeing the same problems — leaking heat-sealed grease tubes, messy storage, and unreliable supply chains — we knew there had to be a better way.

We developed a patented plastic cartridge system designed from scratch to eliminate leaks and improve performance. The result is LeakLock™ — a no-leak grease tube that's cleaner, tougher, and more reliable than anything else on the market.

From there, we expanded into grease filling to create a fully integrated solution. Today, NMI manufactures the cartridge, fills the grease, and delivers finished product — giving buyers a single-source partner they can count on.
