This paper mainly deals with the performance requirement for chrome plating plastic components. These days, decorative parts have taken a big space in the market and specifically in automobile market; chrome plating over the plastic has replaced decorative steel chrome plated parts. Therefore the performance of metal layer with the plastic substrate is an important factor. In spite of various researches on adhesion of metal layer with plastic and problem of early corrosion of chrome plating layer, there is a lot of scope for improvement. Decorative chrome plating involves the electroplating of nickel on the object which is followed by chrome plating layer. In most of the cases, first copper plating is performed on the substrate. Nickel plating is performed over the copper plating and the chrome layer comes over the nickel layer which is the topmost layer of electroplating. Nickel plating provides smooth surface finish and good corrosion resistance. Chrome plating layer gives the decorative finish to the part. The chrome plating is a very thin layer. The metal plating and zinc coatings have been replaced with the plastic chrome plating. The increasing demand for plastic chrome plating is due to following reasons: • Plastics can be molded into any shape and design by injection molding process which is performed in a hard tool called mold. • Being light in weight, Plastics chrome plating parts are used for automobiles. It reduces the weight of vehicle and vehicle requires lesser torque to move. It increases the fuel performance. Processing of plastic material is very easy. Part of any shape and design can be molded and then chrome plated to give it good aesthetic appearance A decorative chrome plated surface, such as monograms, grills and wheel rims are actually the effects of the chrome plating. These are manufactured by a critical manufacturing process of electroplating. Plastic components can be chrome plated from various chemical tanks of Acid, Copper, Nickel, and Chrome. Electroplating process has lot variables which sometimes result in poor adhesion of plating layer and poor corrosion resistance. Experts have been continuously working over to improve the plating adhesion, corrosion resistance life and to control rejections. Over the years, the chrome plating manufacturing process has been upgraded. In spite of these improvements, a very good process control and quality of plastic base material are required. In this paperwork and experiments on injection molding process parameters, mold design and role of plating thickness to improve thermal cracks will be covered. Tool design section has also considered improving the adhesion of metal layer with the plastic substrate. In this paper, the thickness of metal layer has also considered improving its adhesion with the substrate. This paper also covers the research on the factors to improve another failure mode of corrosion over the chrome plating surface. Research factor such as micropore and a potential difference of nickel layers has also been taken into consideration.
