Summary for zamac porosity Discussion
Zamac with high porosity is the central problem in this thread, where the questioner says the process cannot cover the pores. The excerpt provided does not include any technical replies or troubleshooting steps, so no specific plating or finishing remedy is stated in the visible text. The only named contributor shown is Ted Mooney, P.E. RET, who appears in a site notice inviting users to contact him for difficult diecastings and project assistance. Because the actual discussion answers are not present in the excerpt, the thread cannot be summarized beyond noting that it concerns a difficult diecasting/plating coverage issue on porous zamac and that further expert help was being offered.

Q. What can I do if my process does not manage to cover all the porosity of the ZAMAK part? My process includes two cyanide copper baths (strike and plate) and a satin nickel.

A. Hi Luis.
Sorry, but I can’t offer much encouragement. Zamak parts need to be non-porous and free of cold shuts ⇦ huh?. If you can’t get quality diecastings I think you would need to vacuum impregnate them before plating.
You won’t appreciate the humor at this point, but thread 323/05 relates my experience with a fellow in the position of desperately needing to plate unplateable castings.
Luck & Regards,
