20.07.2018 CNC-Laserwelding machine

 

increased requirements in quality for laserwelded pressfit areas was the reason to develop our own CNC-laserwelding machine:

 

Progress:

      • Single pins punched
      • 2nd contour lasercutted
      • assembled and laserwelded

Advantage:

Pressfit pins in individual distances

without expensive tool changes for punching tool

stamping-grigs in Press-In-Technology, raw-material milled area in thickness:

B-samples:

  • Milling on convential milling machine, tolerances in thickness +/-0.015
  • Lasercutting out of pre-stamped strip-material (press-in area) - plating-strips
  • Coining of connectors
  • Plating both sides individual
  • Bending
  • Singulation

Connector-Modul in Press-In-Technology (Engine nearby Application):

from prototype (functional sample) to C-sample:

  • lasercutting out of pre-stamped strip-material (press-in area)
  • coining of connectors
  • Plating (Cu, Ni, Sn100 and Ag, passivated)
  • Molding (PBT GF30)
    (separation of contacts in molding toll integrated)
