A strong, rotation-resistant clinching method for joining harder materials or multiple layers of sheet metal.

What is Lance-N-Loc®电玩菠菜登录首页

Lance-N-Loc® is a sheet metal clinching system which creates a strong mechanical joint by lancing the 2 long sides of the joint and gradually drawing the ends. The material on the sides of the joint is compressed and interlocked, while the gradually sloping ends allow harder materials to be joined making higher strength joints, all in a single press stroke.

电玩菠菜首页登录 Lance-N-Loc® is not leak-proof.
See Oval-Loc® for a rotation-resistant leak-proof clinch joint.

  • 电玩菠菜代理下载 The first step in the process involves the clamping of the material with a punch side stripper.
  • 电玩菠菜下载平台 Next, the punch draws the material into the die.
  • 电玩菠菜app官网 As the material flows into the die, the die blades expand, allowing the metal to flow into a strong interlock below the bottom sheet.
