Metal chips

I'm handling copper nickel barrel plating somewhere in Philippines. Our prevailing rejection is metal chips that occurred mostly on the inside portion of the emboss/air pocket. we've done so many countermeasures such as cleaning of copper and nickel tank, electrotreatment, renewed the degreasing solution, conducted ultrasonic cleaning and controlling all standard parameters . any idea where this metal chips come from and how it was formed?

Are your parts going through an acid bath after the copper plate? If so what type/concentration of acid.
