Frequently Asked Questions

What defines “large tonnage” in injection molding?

Any press with 1,000 tons or more of clamping force. Cascade’s large tonnage machines range from 1,000 to 9,000 tons.

Can you handle custom materials or recycled content?

Yes. Our materials lab is one of our key differentiators. We regularly mold with non-traditional and recycled plastics.

Do you only take high-volume projects?

We specialize in long-term contracts and high-volume work, but we’re always open to discussing new opportunities.

How fast can I get a quote?

Typically within 1–2 business days once we have part specs or drawings.
