[Case Study] Improvement of Cold and Heat Repetition Resistance of Resin-Plated Products with a Bias Toward Meat
Due to having a consistent production system (molds, molding, plating processing), it is possible to consider and implement total solutions.
We would like to introduce a case where we solved the issue by improving the cold and heat cycle resistance of thick-walled resin plating products. The problem was that decorative chrome plating was applied to PC+ABS, but the coefficients of thermal expansion of the metals that make up the decorative chrome plating—copper, nickel, and chromium—are significantly smaller compared to PC+ABS. As a result, the plating film could not withstand the stress when temperature was applied, leading to the occurrence of cracks. We proposed improving the shape of the stress concentration points. As a result, the cold and heat cycle resistance was enhanced, allowing us to mass-produce and deliver high-quality products, thereby ensuring safety in the market and gaining trust from our customers. [Case Overview (Partial)] ■ Issues - Decorative chrome plating of thick-walled resin parts, which are touched by hand in automotive components, was being mass-produced by another company, but cracks appeared in the plating in the market, necessitating countermeasures. - We wanted to improve cold and heat cycle resistance as a countermeasure against cracks. *For more details, please download the PDF or feel free to contact us.
