Integration of Resources:
• Integration of global supply chain resources, we purchase bimetal-disc from the world’s largest bimetal-disc material
manufacturer EMS in the Unitd States and case from German supplier who uses stamping forming technology.
• Spring which material comes from NGK Japan and manufactured by Japanese stamping supplier.
• Silver plating technology on case and spring which greatly reduces the contact resistance.
• The key component bimetal-disc produced by fully automated molding equipment and sorted by tunnel oven separation equipment is
good consistency and stable performance.
