Prototyping to Large Volume

We help you take your ideas from paper to plastic. We’re here to meet your specific needs and we know that sometimes you need something special. Whether you’ve got an idea you’d like to prototype or have a large volume project, you can rely on our professional team to deliver on-time through every step of the project. We believe in customer service first and we’ll be in direct communication with you to keep you informed at every step.

If you are trying to start a new business, we can offer suggestions on new product introduction. If you only need your idea committed to professional drawings, adjusting for the idiosyncrasies of the molding process, we are there. We can counsel on the issues of kiss-offs, under-cuts, tapered walls, reinforcements, and parting line / venting placements.

Servicing many different special customers since 1999. Our unique background gives us a special view into solving design issues and altered projects to provide lower costs. We bring to the table an unusual view of things. We ask a lot of questions and we challenge conventional thinking. 

Custom Plastic Molding

Seamless molded items built to your specifications. Whether you’re casting for a prototype or production run, we can handle the load. Plastic is perfect for creating long lasting, lightweight, and durable parts. Have a complex design? Our experts can build parts constructed of many molded pieces.

We offer much more than just molding plastic for your project. Desert Plastics gives you access to our plastic experts and full service  to bring your project from idea to production. We are ready to meet any challenge and exceed your project’s requirements. 

Rotational Molding Services

Rotational molding (also known as rotomolding / rotocasting) uses centrifugal force to coat the inner walls of the molds with plastic and can create low-stress, seamless, hollow plastic parts. We create for you a hollow mold which is filled with a calculated quantity of powder and spins in an oven until the mold has been evenly coated with the desired thickness. The part is then cooled and removed from the mold.

We can create parts in many different sizes, shapes, and complexity. Perfect for prototyping all the way up to large volume.

Hand Fabrication Services

  • Plastic Fabrication Services for Aerospace, Artwork Protection, Architectural Models, Laboratory Equipment, Medical Equipment, OEM Manufacturing, Prototyping, R&D Projects, Retail or Restaurant Displays, and Scientific Equipment

In custom molding, we currently stock (32) solid and speckled colors but we can customize to any color. Within the sheet plastic arena, many colors are available.


The most common fabrication materials are Polyethylene, Acrylic, and Polycarbonate. Other materials we have used in fabrication are Polypropylene, PETG, PVDF (Kynar), ABS, and PVC. There are many other plastic types available to us. Please inquire.


In custom molding, molded-in Inserts will dramatically reduce the assembly time of most projects. The most common materials are Aluminum, Brass, and Stainless Steel. While most are threaded, there is quite a variety available including custom configurations. Let us know what you need.


In plastic molding, there are many styles of fittings that can be welded into place almost wherever you want. Plastic welding produces strong, leak-free, and very cost effective options.


The fine cutting and etching of a commercial laser is far better in detail than can be accomplished on even the best CNC Router. We’ve got one.
