Learn how we can get you from concept to full scale production

Step 1: Design Your Part

It all starts with a drawing.  Submit whatever you have: 3D models, 2D models, or a sketch on the back of a napkin.  Our engineers will work with you to make your design applicable for injection molding or thermoforming.    If you don't have a design created, contact us, and allow us to help you through the design process.  Depending on your needs, we can provide as much or as little design assistance as needed.

Step 2: Request a Quote

To get started with your quote, please Email us the following:

  • 2D Part Drawings (.pdf, dxf, dwg...)
  • 3D Part files (.stp, .igs, .x_t, .sldprt, we run the latest version of SolidWorks and we can open most files)
  • Estimated annual ordering quantities

Within two to three business days, we'll provide a quote for tooling and part productions.  Depending on your needs and sourcing preferences, we may build the tool in-house or with one of our three tool building partners.  We may also source your tooling from one of our overseas partners to reduce costs.  Regardless of where your tool is built, we will always produce your parts in-house in our factory in the United States.  

Step 3: Submit a P.O.

Upon receiving your order, we'll get started working:

  • First, we'll build a new injection mold or thermoforming tool for you.  You don't have to think about the design of your tooling.  Our engineers take care of all of it.  
  • Once the tool is complete, we'll work with your engineers to establish quality standards.  Every production lot is inspected before it leaves our factory to guarantee quality for our customers.
  • Lastly, after establishing quality standards, we're ready to make your parts. We’ll produce any quantity you need for each order that you place with us.
