Gallagher Case Study: Design and Fabrication of Custom Molded Gasket

Gallagher Fluid Seals helps meters & instruments manufacturer through the design and fabrication of a custom-molded gasket with an engineered profile.

 

The Problempicture of micro corrector

Our client’s micro corrector was experiencing water intrusion past the gasket, caused by improper seal material and configuration.

The Approach

Gallagher Applications Engineer Benjamin Mell worked closely with our client to identify & address the issue and suggested sending a sample of the instrument to GFS headquarters. Our engineering team received the hardware and investigated the root cause of the seal failure.

GFS engineers observed that our client’s closed-cell foam gasket had taken a severe compression set. This was limiting the life & effectiveness of the foam seal, which in turn allowed water to penetrate the instrument and damage the electronics.

The Solution

Based on our experience and industry insights, GFS was contracted to design & fabricate a custom-molded gasket with an engineered profile to properly mate with the hardware and perform to customer expectations/ requirements. (see Figure 1. red seal)

Results / Next Steps

The Gallagher-engineered gasket solution was a success; it eliminated water intrusion and damage to the electronics, reduced warranty claims, and provided a more reliable product.

With the success of this project, GFS is partnering with our client for additional custom solutions. Next, we plan to help design and fabricate a window seal on the micro corrector to further decrease the possibility of water intrusion.
