Injection molding,
built for volume.

One process, done well. We run thermoplastic injection molding at production volume from our North Lewiston plant, for manufacturers across the Northwest and the West Coast.

What we mold

A production molder, close to home

Cascade Plastics is a production injection molder. Our Lewiston plant was built to run lightweight, high-volume parts day in and day out: the kind of work where cycle time, material cost and freight decide the price.

Today that means plastic trays and packaging for the ammunition industry. We're also taking on new programs from manufacturers across the Northwest and the West Coast who want a dependable molder a short drive away.

Capabilities

What we bring to a program.

01

Injection molding

Thermoplastic parts molded at production volume, from small components to large, thin-wall trays. We set each program up for steady, repeatable output, then keep it running.

02

Trays & packaging

Our specialty. We mold the trays ammunition makers use to package cartridges, and we bring the same thin-wall know-how to inserts, containers and other packaging components.

03

Bulk resin on site

Three silos beside the plant hold resin in bulk. Buying material that way keeps supply steady and helps hold down part cost on long runs.

Group support

Cascade is part of a family of molding plants in Minnesota and Arkansas. Group companies mold ammunition packaging, medical device components and containers for personal care products, so the Lewiston team has a deep bench of molding experience behind it.

Program launch

From the first conversation to steady production: we review your part, talk through material and tooling, send first-article samples for approval, then run to your schedule.

Getting a quote

What to send for a quote.

The more we know up front, the faster and more accurate the quote. Send what you have and we'll ask about the rest.

  • A drawing or 3D CAD file. STEP or IGES is ideal. A sample part works too.
  • Estimated annual quantity and typical order sizes.
  • Material, if you know it, or what the part has to stand up to.
  • Timing for samples and for production.
  • Existing tooling, if there's already a mold for the part.
Not sure about material or tooling? That's what the first conversation is for. Call Steve Ciatti at (612) 599-1939.
