dkPOWER - Arnold & Shinjo - PIAS PNC Piercing Nuts

For the cost-effective use of piercing nuts in the production of sheet metal parts there is hardly a fastener more ideal then the PNC piercing nut. Depending on metal thickness the nut must have a pre-pressed boss.

Cost advantages exceeding 40 % compared with normal welding processes are a decisive argument in favour of this type of piercing nut. Key application areas, as seen by ARNOLD & SHINJO, are the electrical, the automotive, and the metal furniture industry.

To install the PNC piercing nuts, ARNOLD & SHINJO provides a modular tooling range. Punch heads, dies, feeding devices and the necessary control systems are part of the standard supply programme.

Çalışma Prensibi
Stage 1 - Start The nut is guided by the punching sleeve until the nut hits the sheet metal.	Stage 2 - Press Stroke While moving down, the punch collar of the nut punches the hole in the sheet metal.

Stage 3 - Punch Process The waste material from punching the hole falls through the centre of die and the sheet metal is pressed into the undercuts of the nut.	Stage 4 - Clinching Process The press is at BDC and the sheet metal is fully clinched into the undercut of the nut.
