Prototype Design

We will transform your idea into to a working product. 

We will work with you to create a Computer Aided Design (CAD) Model of your product using Solidworks 3D CAD software. This digital prototype allows you to see a 3D model of your product on a computer screen that we can rotate, zoom, place in a realistic environment or make photo realistic renderings of your product. 

This stage of the product design is one of the best times to fine tune the design because changes to the 3D CAD model are quick and easy. 

We can perform structural analysis on the prototype CAD model to make sure it is going to be strong enough or thermal analysis to make sure any electronics stay cool enough. Once the customer is satisfied with the 3D CAD model, it is used to create engineering drawings and a physical prototype.

Prototype Fabrication

We fabricate and deliver your prototype in a timely manner and at a competitive price.  We can manufacturer your prototype using appropriate manufacturing process including: 

  • Machining
  • 3D printing
  • Sheet metal fabrication
  • Water jet cutting
  • Laser cutting
  • Welding
  • Molding and forming

A physical prototype can be fabricated from metals such as steel or aluminum or plastics such as polycarbonate or ABS plastic or any other material desired. Whether you are looking for proof of concept prototype or a pre-production prototype, we can help you pick the best materials and manufacturing processes to ensure your prototype and eventual product will be successful.

We always offer free consultations, quotes and estimates
