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.

Injection Molding Drag Marks: Who Owns the Problem?
Drag marks don't become expensive when they show up on parts. They become expensive when three vendors all stare at the same defect photo, but everyone claims it belongs to someone else. We see this constantly with new tooling launches and transfer programs: the buyer leans on the molder because the molder shipped the parts, even when the real cause was built into the steel or the geometry→
New Tool or Injection Mold Transfer? Price Your Next 500,000 Shots
Your decision to get an injection mold transfer is simpler than you might think, but many still end up making the wrong call. When your program has been running for a long time, but the molder relationship isn't working — maybe pricing is drifting, lead times are becoming inconsistent, or quality holds are becoming routine — most people’s first instinct is to start getting competitive quotes.

From CAD to “Click”: How We Engineer Seamless Device Housings
“Seamless” is marketing language. In manufacturing, achieving seamlessness means controlling constraints now or facing costly rework, scrap, and warranty returns later. Many device housings appear perfect in your CAD file because your software has no opinion on parting lines, sink, warp, or what happens after 50,000 cycles on a 440-ton press. CAD also won’t protect you from tolerance stacking when every component lands at the edge of its→
