High-Volume Injection Molding with Tight-Tolerance Precision
H&H has spent decades refining our mold-making & injection molding techniques. We don’t just ship custom parts — we create molding components that keep your production 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, serving industries across the spectrum. Over the years, we’ve built a reputation for delivering cost-effective solutions that never compromise quality. Our journey began with a focus on craftsmanship, and today, that same commitment drives our pursuit of innovation and excellence.
We specialize in low volume, tight tolerance molding of engineering and commodity grade thermoplastic resins.
Whether you need engineering-grade thermoplastic parts or commodity-grade components, our dedicated team ensures that every project is completed with meticulous attention to detail. This dedication has allowed us to evolve into one of the Pacific Northwest’s most trusted names in injection molding.

Glass-Filled Nylon – The Gold Standard for High-Stress Tactical Parts
Walk the floor at Shot Show, and you’ll see the same polymer DNA everywhere. Glock frames, Magpul stocks, Safariland holsters—all built on glass-filled nylon. The industry didn’t just drift here. It sprinted. If you’re designing tactical parts for firearms, you’re not in the business of reinvention. You’re in the company of domination—where “what works” beats “what if.” Glass-filled nylon isn’t just the material of choice; it’s the kill→
The Economics of High-Volume Injection Molding
If you’re chasing thousands—or millions—of identical parts, your spreadsheet will eventually point to one glaring need: plastic injection molding. Volume Changes Everything Let’s skip over the craft-fair mentality. In low quantities, 3D printing or CNC machining looks nimble—no tooling, low setup, quick pivots. But as soon as your sales team starts talking in truckloads rather than units, those methods collapse under their own cost structure, making high-volume injection→
What Actually Happens Inside a Plastic Injection Mold
Ever wondered what actually goes on inside a plastic injection mold—after the clamshell closes, but before that shiny new part pops out? It isn’t magic, but it’s close. Let’s demystify this complex process and walk you through it, from heat to ejection, without the corporate jargon. The Pressure Cooker (a.k.a. Clamping and Heating) Picture a waffle iron with a vendetta against chaos. That’s your injection mold. It begins→
