High-Volume Injection Molding with Tight-Tolerance Precision
H&H has spent decades refining our mold-making and custom injection molding techniques. We don’t just ship parts. We build the injection mold tooling behind them, then run production on our own presses — the molding components that keep your lines running at full steam.
H&H Molds is built to withstand global trade volatility:
Many manufacturers remain vulnerable to shifting tariffs and overseas uncertainty. Supply chains can crack virtually overnight. That’s why H&H keeps the core of your project anchored firmly on US soil. Even if a build involves global components, your work will remain protected under American standards, accountability, & oversight.
Since 1952, as Pre-Met and eventually H&H Molds, we have been at the forefront of precision injection molding and mold making from our plant in Spokane Valley, Washington. Over the years, we’ve built a reputation as the injection molding supplier that delivers cost-effective work without compromising quality. Our journey began with craftsmanship. That same standard drives everything we build today.

That’s the real range, and every figure in this guide stays a range on purpose — anyone quoting injection mold prices to the dollar without seeing your part design is just guessing. What you can pin down is why a quote lands where it does: the steel grade,→
Injection Mold Repair Isn’t an Oil Change — It’s Insurance
Here’s a hot take: injection mold repair belongs in your budget the same way an insurance premium does, as a known cost paid ahead of a loss you can't schedule for. That kind of logic is already accepted everywhere else in the company. Mold repair usually gets thought of as maintenance—roughly the same mental shelf as an oil change—which is why it can wait until next quarter, and→
Medical Device Injection Molding: What Validation & Traceability Actually Require
Ask a medical device injection molder for a first article inspection report, the CMM data sitting behind it, and the resin lot record for a given production run, and you'll learn more in an afternoon than a stack of certificates and a walk through the plant can tell you. Certifications and tours describe the building. Whether cavity three on your tool has drifted since the last audit? That→
