The impact of in-mould coating on products is mainly reflected in improving the wear resistance, flexibility, surface quality and appearance expression of the product.
In-mold coating, also known as in-mould coating, is a series of paints used for coloring, decoration, and protection of polyurethane material parts. It has good wear resistance and flexibility. Through the most advanced in-mold spraying and post-casting molding process, the colored paint product and the polyurethane material are organically combined into one,thereby effectively blocking the yellowing of the foam. , Improve the surface wear resistance of foam materials, Strengthen the adhesion of paint on the surface of materials, Cover surface defects caused by the foaming process. At the same time, the application process of in-mold coating can enable the molded product to truly reproduce the mold texture, improving the expressiveness of the product's appearance.
In addition, the application of in-mold coatings is not limited to polyurethane material parts. Its functions include:
Reduce wear and friction:By increasing the hardness and wear resistance of the mold surface, reduce friction,thereby reducing the degree of wear of the mold.
Improve demoulding performance: Improve the finish and smoothness of the mold surface, make the product easier to demould, reduce the adhesion between the mold and the finished product, increase production efficiency.
Improve corrosion resistance: Some special coatings can improve the corrosion resistance of the mold, making the mold more resistant to contact with some chemicals or special processes.
Improve thermal conductivity and electrical conductivity: For some special applications, mold coatings can improve the thermal conductivity or electrical conductivity of the mold to better meet specific industrial needs.
Increase the smoothness of the mold surface: Thus improving the surface quality of the product, In some industries that have higher requirements for product appearance, such as automobile manufacturing, home appliance manufacturing, etc., the application of mold coating can make the product more attractive Aesthetics.
In summary, in-mould coatings have a positive impact on products by improving their wear resistance, flexibility, surface quality and appearance expressiveness,as well as increasing the smoothness of the mold surface.
