Products Gasket(CIPG)

Alpha GEL Cured-In-Place Gasket (CIPG) is applied with an automated system directed by 3D plotting software and cured in place with UV light. Its elasticity, compressibility, and ability to follow part warpage impart Alpha GEL CIPG with its superior water and dust proofing functionality.

Characteristics
Alpha GEL CIPG is designed with a perfect balance of material properties both before and after UV curing.
Thanks to the power of UV curing, Alpha GEL CIPG hardens more quickly than standard moisture curing, reducing process time.
Automated application eliminates the need for injection molds and assembly processes required by traditional rubber gaskets. This lowers production costs and improves efficiency.
Application Example
CIPG (Cured-In Place Gasket) technology is a state-of-the-art gasket solution using Alpha GEL. It offers excellent waterproofing and dustproofing for smartphones and tables.
