Abstract
The invention relates to a method for repairing a plastic-steel mould by brush plating. A coating is brush plated on the abrading section of the plastic-steel mould, and the oversize size is restored. The process flow of the repairing method includes: degreasing, surface oxide layer removing, activating treatment, bottom coating, working layer plating, ground finish and polishing. The brush plated coating meets the requirements of working condition of the plastic-steel mould, has characteristics of wear resistance and corrosion resistance. The process equipment is simple, low-cost and economically practical.
