Shielding gasket

Introduction

Nowadays, with the rapid development of mobile communication technologies, we are facing a lot of serious problems related to electromagnetic waves from IT products. To cope with these problems, it is necessary to use the EMI Shielding products. We have a wide range of EMI Shielding and Conductive Products, related to the computer, telecommunications, military equipment, general electronics, medical equipments and automotive industries. These include Fabric Gasket, Gold Gasket and Cushion Gasket. Our EMI Shielding Products has been awarded ISO 9001 and 14001 certification and has patents unique designed to perform good shielding effects. And they have meet UL requirements.
