Put Our Press Fleet to the Test
Bring us your most complex design challenge. We’ll engineer the resin, validate the tool, and mold at scale so your part works exactly as it should.
Our Process
How We Do It
Engineering & Materials
We start with CAD modeling, DFM, and flow analysis, then test and validate resins in our A2LA-certified lab, including recycled and bio-based plastics.
Design & Tooling
We prove out designs through rapid prototyping and mold trials, then move into tool design, qualification, and integration with our press fleet.
Production & Assembly
We mold at scale and finish parts in custom work cells built for automation, assembly, and packaging.
Circular Economy
We build recycled materials into parts and design for end-of-life reuse, closing the loop wherever we can.
Why Us
Why Choose Cascade Engineering?
Wide-Ranging Manufacturing Capabilities
From small precision components to oversized structural parts, our engineering and press fleet give you the flexibility to build what others can’t.
Our Triple Bottom Line: People, Planet, Profit
We invest in people, design with sustainability in mind, and prove that business success and social impact can go hand in hand.
Woman-Owned & Michigan-Based
Founded in Grand Rapids in 1973, Cascade is still family-owned and woman-led today. With more than 50 years of experience, we’ve grown into one of the Midwest’s most trusted plastics partners.
Solutions That Scale
Industries We Serve
Waste & Recycling
Recycled-content compounds that support circular material use while delivering the durability needed for long service cycles.
Automotive

FAQ
Frequently Asked Questions
They design, test, and optimize plastic parts, choosing the right materials and processes to ensure durability, cost-efficiency, and manufacturability.
Costs vary widely based on size, complexity, and cavity count. Smaller tools may cost a few thousand dollars, while large, multi-cavity molds can reach six figures or more. We’ll provide a custom quote based on your design.
From consumer products to industrial components, plastic engineering covers everything from small precision parts to oversized structural pieces.
Yes! We incorporate recycled resins, bio-based fillers, and closed-loop regrind programs into many of our products.
It begins with CAD design and material selection, followed by simulation, prototyping, tooling, and full production in an injection molding press fleet.
