Tech Brief
How to Ultrasonically Weld
PTFE Protection Vents

What you will learn in this tech brief:

Audience: design engineers, automotive manufacturers

Summary: Electronic devices across industries such as healthcare, consumer goods, and automotive need protection vents to protect the electronics inside; however, the expanded PTFE (ePTFE) material that many vents are constructed of is delicate and can’t handle the rigors of automated assembly processes such as ultrasonic welding that would save manufacturers time and money.  In this tech brief, learn about protection vents made from sintered PTFE, the stronger option that can withstand any automated assembly process to make the manufacturing process more efficient.  This tech brief is intended for design or manufacturing engineers working with devices that require protection vents but are limited in their assembly options due to ePTFE.  Engineers will understand the differences between the two materials and how to determine which material is best for a particular application.
