How the Process Works
Share Your Project Details
Send us your part drawings, specs, or a description of what you need. We’ll put together an estimate for tooling and per-unit pricing based on your design and expected order volume.
Design Review & Tooling
Once you’ve approved the quote, we work with our trusted tool builders to go through your design and address anything that could affect manufacturability or cost.
Sample Review
Before any full production run starts, we produce initial samples for your review. You sign off before we move forward.
Production & Delivery
Once samples are approved, production begins. Lead times vary based on order volume and project complexity, but our team works efficiently to manufacture and ship your order as quickly as possible—straight from our Yakima facility to your door.

What Affects the Cost of Custom Thermoforming?
Pricing on custom thermoformed parts depends on a few key inputs:
- Tool complexity: The number of cavities and the intricacy of your design affect tooling costs.
- Material selection: Different plastics come with different cost and performance profiles.
- Part size and weight: Larger or heavier parts consume more material and machine time.
- Order quantity: Higher volumes generally bring down the per-unit cost.
Send us your specs and we’ll put together a clear, detailed estimate.
