Contract Molding Services

High-Volume Plastic Parts Built to Last

Build durable, large-scale plastic components with precision and speed. Cascade Engineering helps you bring complex designs to life using advanced materials, engineering support, and one of North America’s largest molding fleets.

Our Contract Molding Services

Contract molding is a full-service manufacturing partnership in which you outsource the design, tooling, and production of plastic components to an experienced molding manufacturer.

Cascade will act as an extension of your team, offering design assistance, materials expertise, large-tonnage production, and secondary operations to bring your ideas to market faster.

We handle the entire lifecycle, from engineering and tooling through production, assembly, and logistics, giving you complete control and confidence in every molded part.

  • Reduced capital costs: No need to invest in presses, molds, or staffing.
  • Faster time to market: Our engineering, tooling, and production teams operate under one roof.
  • Access to expertise: Gain immediate support from materials engineers and manufacturing specialists.
  • Consistent quality: ISO-certified systems, precision equipment, and sustainable production practices.
  • Sustainability: Our materials lab formulates recycled and alternative resins, including UBQ™ and hemp-based plastics.

Frequently Asked Questions

What industries do you serve?

We mold parts for automotive, furniture, material handling, agriculture, and infrastructure markets across North America.

Can you mold with recycled materials?

Yes. We regularly use hemp-based plastics, UBQ™, and post-consumer regrind. Our materials lab can also help you reach recycled-content goals through custom resin formulation and polymer compounding.

What part sizes can you handle?

We can mold components up to 200 pounds with press capacities ranging from 165 to 9,000 tons.

Do you help with part design or tooling?

Yes. Our engineers collaborate on part design, mold flow analysis, and tooling recommendations to improve manufacturability and reduce cost.

Can you produce prototypes before full production?

We can support pilot runs and early-stage tooling to validate fit and performance before scaling.

Do you offer secondary services like assembly or finishing?

Yes. We can coordinate trimming, assembly, labeling, and packaging based on your production goals.

What materials can you work with besides recycled plastics?

We mold a wide range of polymers, including nylon, PP, HDPE, acetal, and filled resins for strength, stiffness, and temperature resistance.
