| 01/24/2024 | 513543 - Equipment Transfer, Production Transfer or Rearrangement. Production Transfer Nogales recently increased their molding capacity by adding (2) additional 75 ton molding machines and now would like to shorten the supply chain by further reducing their dependency on other plants molding production. Nogales already has (5) Micro-fit 43045 housing molds of various ckt size that were transferred from Little Rock years ago and now would like to obtain the last (3) Micro-Fit 43045 molds from Lincoln for ckt size 4,8 &10. Once the transfer is finished, all 43045 molding housing production in AME region will be consolidated in Nogales plant 3105. It should be noted that Shanghai also molds these same components so the PCN should be limited to only those customers who's demand is filled by Nogales | Download | |||
