  Magnetic Door Gaskets  
 

Magnetic door gaskets are made by welding after inserting magnet strips in PVC rubber sleeves. They are mainly used in refrigerator, disinfecting cupboard and other places where seal is needed.

Now we owns 8 production lines about 40 machines and an entire storey for producing gaskets. We are one of the production partners of Hitachi Ltd. (Japan and South East Asia branches), exporting approximate 60,000 sets monthly.
