Electroless nickel plating on PC/ABS

2004

Good day to all.

I'm designing an audio products and use PC/ABS as the cabinets. I need to do an electroless nickel plating on this PC/ABS material but up till now, not so successful since the plating material does not stick well on the cabinets. Any of you have any idea on how to improve the process or how actually the process of this electroless nickel plating need to be done on the PC/ABS material? Really appreciate the help.

Thank you and regards.
