Medical Electronics Enclosure and Power Supply Shield

Project Overview
The X-Porte is the World’s First Ultrasound Kiosk designed by Fujifilm SonoSite, Inc.

Die cast magnesium was selected as solution for the enclosure.

TCDC provided design feedback using flow simulation software, and based on experience suggested a thin-wall design at 0.04-inches with considerable critical areas to gate and improve metal flow and size of the casting to making the X-Porte a success.

The Challenge


* Slender/Portable/Durable

* Light-weight enclosure

* Protect internal electronic components, while offering appropriate thermal properties, EMI shielding and stability.

Approx. 15” x 13” (inches)

The Solution

Gating: Center Gate / 3-Plate Die
Several different simulations were done with multiple gate changes until the best fill conditions were achieved, and a ribbed pattern was added to improve both flow and fill.

Three castings:

1) Power Supply Cover Shield

  • 10.0” x 9.0” x 1.4” 
  • (254 x 228.6 x 35.6) mm
  • Nominal wall thickness 0.04” (1 mm)
  • Weight: 0.35 lb (0.16 kg)
  • Edge gated
  • Buhler 600 Ton Evolution cast machine

2) Mid Frame

  • 15.25” x 13.0 ” x 2.0”
  • (387 x 330.2 x 50.8) mm
  • Nominal wall thickness 0.04” (1 mm)
  • Weight: 1.25 lb. (0.57 kg)
  • Center gated
  • Buhler 950 Ton Evolution cast machine

3) Bottom Enclosure

  • 15.25” x 13.0” x 1.3”
  • (387 x 330.2 x 33) mm
  • Nominal wall thickness 0.04” (1 mm)
  • Weight:  1.0 lb. (0.45 kg)
  • Center gated
  • Buhler 950 Ton Evolution cast machine
  • Bosses drilled and tapped, installation of dowel pin to aid in final assembly
