所面临的挑战
A leading remanufacturer of automotive brake calipers was having problems with flash rust appearing on their finished goods. What was even worse was the fact that the issue was not revealing itself until after the remanufactured parts were already shipped to retail stores and customers were pulling boxes off of store shelves and seeing the surface rust, forcing the chain stores to return the products to the distributor.
A Senior Technical 产品 Manager for the remanufacturer approached Hubbard-Hall at AAPEX 2015 about solving the flash rust problem, as well as restoring the confidence of the company to distributors of its products.
