What is Proto-Roto?

Proto-Roto™ is a technology enabling quick-turn manufacturing solutions for custom plastic roto-mold parts for prototyping and short-run production by utilizing its proprietary tooling process. Proto-Roto™ provides real parts, real fast.

Why Proto-Roto?

– When you need to validate a design before commiting to production tooling
– When you cannot “real-world” test your 3D printed prototype; Proto-Roto™ allows you to test parts with your production material, run at production temperatures
– When you need parts now; whether for marketing, pilot run parts, testing fit and function parts that go into a larger assembly, or just need to fill the pipeline while your production tool is being built

It’s all about speed to market.

Our Featured Works and Case Studies so far


Do I own the tooling?

The Proto-Roto™ technology involves a consumable tool; once your run is complete a new tool will be required for your next order.

How many parts can i expect?

Your design is an original so there is no accurate way to guarantee production quantities. We will do our best to evaluate the complexity of your design and give you an estimated range when it comes to the life span of the tool.

Is my design ready for tooling?

The Proto-Roto™ technology requires the same design elements that are required with traditional tooling, i.e. parting line, draft, and no undercuts

Can I run my exotic material blend?

Due to the large amount of materials on the market today, we are unable to vet every brand and blend. We are willing to try your material, but there is a shared burden. These situations will be handled on a case-by-case basis. We will do our very best to arm you with the info you need to make the decision, but ultimately we cannot be held accountable for any unapproved materials / resins.

what industries does Proto-Roto™ serve?

Proto-Roto™ is a good fit for anyone that uses production roto-molded products. We build parts for all industries, from medical to agriculture and sporting goods.

How do I get a quote?

Please call one of our representatives at 320-842-3375. They will review your project and walk you through the next steps.

What type of files do you accept?

We can accept native SolidWorks (.sldprt) as well as IGES (.igs), STEP (.stp), or Parasolid (.x_T or .x_B). Two-dimensional drawings are not adequate for quoting or making parts.

What if I don’t have a 3d model?

We can help, please call 320-842-3375 and one of our representatives will align you with a member of our design team.



We'd really love to hear from you so why not drop us an email and we'll get back to you as soon as we can.

Save time with a free, no-obligation quote.

Tell us the details of your project, and we’ll respond with an accurate quote and timeline for the work.

After making initial contact with us we will require a 3D file, please remember to include draft and to have requested parting lines defined.
