Product Development Discovery Call
Product Development Project Estimation
Product Development Design & Analysis
Product Development Prototype Fabrication
Product Development Production

We start with a Discovery Call to learn what your product, device or machine does, why it’s needed, and how it works.

Project Estimation

We quote the scope of the project and the timeline to complete work based off:


1.)  Engineering Time Needed

2.)  Material Costs

3.)  Tooling Costs

Design & Analysis

We create a (CAD) model of your product and use the best design and analysis software to simulate how the product will function in the real world. We determine the best materials and manufacturing processes to ensure performance requirements are met and products are designed for manufacturing. 

Prototype Fabrication

Prototypes allow you to see, hold and feel your product before committing to high-volume manufacturing. We order and assemble the parts needed to fabricate and deliver your prototype in a timely manner and at a competitive price.

Production

We work with a network of skilled manufacturers able to handle high-volume production, packaging, and shipping of your product. This is where we hand the reigns back to you to enjoy the profits of your investment.
