Fusion nails are a preferred attachment for military and police pin badges due to their speed and sturdiness. These nails contain a material that explodes upon contact, securing the nail firmly to the back of the badges. The unique material within these nails ensures a strong and secure bond, making them ideal for situations where reliability and security are crucial. While they may come with a higher price, the peace of mind they offer is invaluable, making them the top pick for law enforcement and military badges.

Fusion nail is not just an innovative choice for practical solutions; it also adds a touch of sophistication to badge appearance, making them stand out. With fusion nails, organizations can trust that their badges will remain intact and prominently displayed, reflecting the professionalism and dedication of those who wear them.

Silver has a higher melting point, which makes the solder stronger. At Jin Sheu, we utilize the silver soldering process for bonding attachments on tie clips, cufflinks, or military and police badges. Silver soldering is labor-intensive, requiring craftsmen to control the heat from the torch gun and the position of each badge and emblem carefully. However, this method results in a very strong and smooth weld. Due to the high welding temperature, a piece of copper plate must first be glued to emblems made of zinc alloy or pewter before the attachment can be silver-soldered onto the copper plate.

Tin has a low melting point and tin soldering is the most economical and practical way to solder pin backs. In Jin Sheu, we utilize two different methods to tin solution or tin bits when soldering. For large quantities, tin liquid soldering is fast applied to the back of the emblems, followed by baking the emblems in an oven to dry the tin liquid and fuse with the studs. Tin bits soldering involves directly melting the tin bits with high heat and when tin cools down, the attachment and emblem are joined firmly together.
