QTI Design & Prototype

Project Samples


Case Study: Electronic Enclosure Design

The Challenge: Design and Build Medical Device

• Originally did not pass EMI• Kept contour design• Reduced components• Cost $150.


Case Study: DFM Analysis

• Designed by Industrial Design Firm

• “No-Quote”• Provided Costs Savings• Product Moved to Quality Tool for Manufacturing

The Challenge: Redesign to Make Product Manufacturable.


Case Study – CFD/ Thermal Analysis

•Initial thermal analysis identified ‘hot spots’ using Flotherm CFD software.•QTI redesigned to add baffle and increase local velocity over hot components.


Case Study: Flush Rivets

•Punch Press•Rivet Gun•Permanent•Flush to Surface•Inexpensive Solution
