We invite you to work directly with our technicians, designers, and project managers. Whatever stage your project is in, we’re ready to help.

What We Do

Robot arm for Robomolding


Our exclusive Robomolding technology creates high tolerances with precision-
distributed heat and material control for consistent part repeatability and optimized strength-to-weight ratios. It also allows for unsurpassed design flexibility including the ability to layer different compounds and coatings into finished parts. For these reasons and more, Robomolding technology is ideal for military, OEM, industrial and commercial applications where precision and unsurpassed repeatability are key.

Robomold Plastic Solutions is proud to be the first manufacturer in the United States to offer this leading-edge technology.

Rotomolding Carousel

Rotational Molding

Rotational molding is a biaxial heat molding process used to produce single-piece plastic parts with complex geometries for rugged, high-impact applications.

Our 3-station rotomolding carousel is ideal for the sequential production of parts in mid-volume quantities with variable wall thicknesses, molded-in metal inserts, and embossed/debossed logos and graphics.


Thermoforming is the process of heating plastic sheets so that they become malleable. They are then stretched over a mold so that the plastic conforms to the desired shape. It is most appropriate for low and deep draw parts, negative draft details, precise definition detail, and multiple piece assembly part sets.

With nearly 60 years of continuous production experience in vacuum forming and cold forming, our capabilities and knowledge are unsurpassed.

Expert Support

In addition to our leading-edge production technologies, our team of manufacturing experts are ready and willing to assist you at all stages of your project’s development. We’ll be with you at every step.

  • Development

Partner with our engineering and production team members early in the development process to create parts that meet stringent MIL-STD standards. We can then produce 3D printed prototypes of those designs and conduct design / material testing to assure foolproof production. Tests include submersion, vibration, air and water tightness, color spectrometer, temperature, impact, and salt / fog / UV assessments.

  • Tool Manufacturing

Design, manufacture and qualify new tools faster and more efficiently by leveraging our tool making expertise. By bringing the tool creation process under the same roof that will ultimately use it, you know the resulting tool will be produced to the exact specs needed to do the job. And because we built the tool, we will know how to maintain it so that it continues to perform reliably into the future.

In addition to new tool creation, we can maintain and repair existing tools including those used in complex rotomolding applications.

  • Design Development, Prototyping & Testing

  • In-House Tool Manufacturing

  • Project Management

  • Materials Sourcing

  • Logistics

  • Production Sub-contracting


Yes, we can probably use your existing mold, however, we will need to inspect the mold to make sure it is structurally sound and that it will fit our machines.

We have a range of standard materials in-house but are always willing to partner to deliver the right solution for the application. Regarding colors, we inventory several standard colors such as black, grey, orange, blue and yellow to name just a few. Custom colors can also be utilized per your project’s specifications.

We stock high-density polyethylene, ABS, and polycarbonate. Conductive, flame-retardant, and medical grade options are also available. With regard to colors, we inventory HDPE sheeting in black and silver along with ABS in black. We can also utilize custom colors per your design specifications.

We utilize vacuum forming, snap-back billow forming, and pressure forming. Each is appropriate for different characteristics in the finished part. Starting gauge thicknesses range from .093 to .275.

Yes. Regardless of whether your part is thermoformed or rotationally molded, we can apply a logo or label to the finished product. It can be either in debossed or embossed fashion. It is recommended to add logos or lettering to rotationally molded products via custom metal plates which is an additional service we can accommodate.

We are ISO 9001:2015 Certified. We also operate so that we can meet the demanding quality standards outlined in MIL-STD-810, MIL-STD-648, and IPX.

We love visitors and the chance to show off our state-of-the-art facility and equipment. Please contact us to set up an appointment with one of our customer service team members.
