Since 1952, H&H Molds has been the quiet backbone behind products that demand precision. What started as Pre-Met has evolved into one of the Pacific Northwest’s most capable mold-making and injection molding partners—trusted by manufacturers who can’t afford guesswork.
From our Spokane Valley facility, we handle the whole lifecycle: design, engineering, mold construction, injection molding, and post-molding operations. Everything is under one roof so our customers get tighter control, faster timelines, and fewer surprises. ISO 9001:2015 certification isn’t a badge for us—it’s how we work.
We specialize in tight-tolerance molding of engineering and commodity-grade thermoplastics, supported by advanced capabilities such as mold flow analysis, CNC machining, sinker EDM, ultrasonic welding, and complete assembly. With 26 presses from 55 to 440 tons, we’re built for both complex low-volume runs and scaled production.
If you’re bringing a new product to market or pushing an existing design further, H&H is the partner that keeps projects on track, high-quality, and built to spec. Precision isn’t something we talk about—it’s something we’ve delivered for more than 70 years.
