MAPT offers service to main vehicle(car) manufacturers. We also offers treatment to other fasteners such as chipboard screws, wood screws, construction screws and composite deck screws. It also differs from traditional factories it controls the quality with its professional staff members. The ion exchanger not only avoids contaminations with foreign substances, but also controls the quality (passivation solution compound) precisely. In addition, each treatment bath is equipped with own rectifier; therefore it costs much more than ordinary facilities provided with only one rectifier for every three bathes.
