At Tamarack Industries, we keep things simple: make good parts, communicate clearly, and deliver on time. Everything we build comes out of our Yakima, Washington facility, where our plastics team handles projects of various shapes and sizes. Whether you’re starting with a brand-new idea or you already have tooling ready to run, we’re set up to help you get the parts or packaging you need under one roof.
Here’s a look at what we offer.
Custom Plastic Injection Molding

We work with customers at every stage. Some come to us with a new product concept. Others bring in existing molds that just need a reliable production partner. Either way, our goal is the same: produce durable, consistent parts that do their job well.
While larger volume orders are more cost effective, we have no minimum order requirements, so whether you need 10 units or 10,000, we can help you get the right results.
Our molding services include:
- Part design and prototyping
- Mold design and testing
- Secondary operations like assembly, welding, and drilling
Our presses range from 25 to 500+ tons, with shot capacities from 1 to 2,267 grams, which gives us the flexibility to make a wide range of sizes of molded parts.
All molding and production work happens here in Yakima. That means faster lead times, direct communication, and easy domestic shipping.
Custom Plastic Thermoforming

We also produce custom thermoformed packaging for a wide range of industries. If you need trays, lids, blisters, clamshells, or completely custom containers, we can help you create packaging that fits and functions the way it should. Again, no minimums, so you’re free to order exactly what you need.
Our roll-fed form trim stack system is built for efficient, high-volume production. We can form pieces up to 30 by 48 inches using plastic up to 0.060 inches thick.
We work with several types of sheet plastics, including:
- RPET (recycled PET)
- PET
- HDPE
- Polypropylene (PP)
- PVC
- Styrene
From design to final shipping, every step happens in-house in Yakima using materials from suppliers we’ve trusted for years. It keeps quality consistent and lead times predictable.
Built in Yakima. Shipped Nationwide. Ready for What’s Next.
At the end of the day, we’re here to make your job easier. If you need custom molded parts or thermoformed packaging and want a partner who keeps things clear, straightforward, and on schedule, our team is ready to help. Find us at www.tamarackindustries.com.
