Injection molded thermoplastics parts may need to be coated to facilitate paint adhesion, or to surface property requirements, such as appearance, durability, and weather resistance. Injection molding as a fabrication method for plastic products has a high productivity and can be easily obtaining uniform quality products. However, the application of a coating to an injection molded part is still a time-consuming and cost-intensive procedure. Additionally, the post-coating processes can emit Volatile Organic Compounds(VOCs), some of which can have short- and long- term adverse health effects. In order to solve this problem, The In-Mold Decoration process is an innovative method integrated with the injection molding and the coating processes because plastic injection is proceeded in molds after closing and holding the polymer film between the upper and lower molds. In this study, we will establish IMD process conditions of the CTR-Panel for automobiles.

Recently, Automotive manufacturers are researching on a light-weight vehicle for reducing CO2 and VOCs(Volatile Organic Compounds) emissions to meet International Environmental Regulations. As a methods for light-weighting the automobile interiors, the design and process changes such as thickness reduction of products and/or blow foaming injection molding process using foaming agents are considered. However these changes have many problems during the injection molding process such as short-shot, deformation and etc. In order to solve these problems, we are focused on Micro-cell Injection Molding Process to secure the product quality and to establish the process conditions.
