Plastic Fabrication

Minnesota Plastic Fabrication.

Custom and prototype parts via CNC routing, line bending, die cutting, and polishing, plus screen and digital printing and assemblies that can include non-plastic materials.

Overview

Custom, prototype, quick-turn.

Fabrication builds parts without hard tooling, so it's the fastest path to prototypes, low volumes, displays, and fixtures, and a flexible way to combine operations on one part.

CNC routing, line bending, die cutting, and polishing are paired with printing and full assembly, including non-plastic components.

  • Quick-turn prototyping. Parts without the wait for tooling.
  • CNC routing & cutting. Tight, repeatable machined parts.
  • Line bending & forming. Clean folds and formed shapes.
  • Assemblies incl. non-plastic. Complete, finished assemblies.
Minnesota

A Minnesota fabrication partner.

Plastic Alternatives has worked with Minnesota manufacturers since 1989. We’re based in Independence, in the Minneapolis-Saint Paul area, and most of our customers are within a short drive, so print reviews and quality conversations happen face to face when they need to.

Production runs through our U.S. manufacturing partner network under our ISO 9001:2015 quality system, so parts ship Made in the USA wherever you are.

  • Twin Cities metro. Minneapolis, Saint Paul, Bloomington, Plymouth, Maple Grove, Eden Prairie, Minnetonka, and across the metro.
  • Greater Minnesota. Rochester, St. Cloud, Duluth, Mankato, and manufacturers throughout the state.
  • Nationwide. Programs ship across the United States from our domestic partner network.
  • Talk to a principal. The people who quote your job are the people who guide it. Meet Steve and Spencer.
How it works

We turn prototypes fast, with no hard tooling required.

02

CNC routing & cutting

Parts machined and die-cut to spec.

03

Line bending & forming

Precise bends and formed geometry.

04

Printing & finishing

Screen/digital printing and polishing.

05

Assembly

Full assembly, including non-plastic materials.

Materials

Sheet and rod that fabricate cleanly.

Fabrication starts from sheet and rod that machine, bend, bond, and polish cleanly. These are the usual choices, and we’ll help you narrow it down.

Design tips

Design it to fabricate.

Fabrication is the fast path for prototypes and low volumes, and the only path for some large or one-off parts. The best parts are designed with the process in mind from the start.

  • Standard sizes. Design to standard sheet and rod sizes.
  • Bend radii. Respect minimum bend radii in line bending.
  • Edge finish. Call out edge finish (machined, flame-polished, or buffed) wherever it shows.
  • Realistic tolerances. Tighter-than-needed tolerances add cost. We’ll tell you what’s achievable.

Applications

Where it fits.

  • Prototypes. Functional parts, fast, before committing to tooling.
  • Displays & signage. Polished, printed, retail-ready.
  • Fixtures & jigs. Shop fixtures and tooling aids.
  • Enclosures & guards. Machine guards and custom housings.
Across industries. Fabrication builds displays and fixtures for consumer products, fabricated assemblies for building and construction, prototypes through finished parts for defense and aerospace, custom parts for industrial and OEM equipment, and seasonal runs for recreation.
When to tool up

Fabricate now, tool later.

Fabrication carries minimal tooling cost, so it wins for one-offs, prototypes, and low volumes. You can start in fabrication or forming, then move to injection tooling once volume justifies it, and we quote both routes.

FAQ

Common questions.

Can you make prototypes quickly?
Yes. Fabrication is our quick-turn route. Because it doesn't need hard tooling, we can produce functional prototypes and low volumes fast.
Can assemblies include metal or other materials?
They can. We build complete assemblies that include non-plastic components.
What printing do you offer?
Both screen and digital printing for branding, legends, and graphics.
Where are you located?
In Independence, Minnesota, in the Minneapolis-Saint Paul area. We’ve worked with Minnesota manufacturers since 1989, most of our customers are within a short drive, and parts ship across the United States from our domestic partner network.
What plastics do you fabricate?
Common choices are acrylic, polycarbonate, PETG, PVC, HDPE, and ABS: sheet and rod that machine, bend, bond, and polish cleanly. We’ll help you pick the right one for how the part is used.
When should a fabricated part move to molding?
When volume justifies the tooling. Fabrication has minimal tooling cost, so it suits one-off and low volumes, while molding pays back at higher volumes. Our tooling break-even calculator compares the two, and we quote both routes.
Do you review designs before quoting?
Yes. Our DFM review is free. We check geometry, material fit, process selection, and cost drivers before you commit.
