Our Process

Step 1: Design

Our engineering team will work with you through our Design for Manufacturing (DFM) process to either optimize your current design or design a part from scratch to meet your specific requirements. Our process includes reviewing the materials needed, the functionality of the design, the moldability of the part itself, and any tooling optimization.

Step 2: Prototyping & Validation

Once the design is approved, we can move on to prototyping the part to validate that it works for your application. The two methods we use to do this are:

  • 1-Week Silicone/EPDM Rapid Prototyping:  We developed a proprietary method of creating silicone and EPDM prototypes to give you the ability to test apart's fit, form, and functionality - Learn More Here.
  • Standard Prototype Tooling: To get the truest to-production prototypes, you can go the standard route where we will machine a metal mold (typically will be aluminum due to the speed to produce tool) mold to produce your parts.

Step 3: Quality Assurance & Validation

Once prototypes are completed, we inspect and test them (when needed) to ensure they meet your requirements before shipping them to you to test out. If anything is off, we will make revisions and repeat.

Step 4: Tooling Kickoff

Once everything is approved, and a PO is submitted, we will begin production tooling design and kickoff. Part complexity and quantity factor into the timing required to complete the mold. Production tools are typically made using hardened tool steel instead of aluminum.  This allows our die life to be extended, reduced maintenance on the dies and a more efficient manufacturing process overall.

Step 5: Production

Once the first shots from the tool are reviewed and approved, the first articles are provided to the customer for their final approval.  Pending any final modifications needed, we are able to start fulfilling production quantity orders to ship to the customer.
