Imd is a special plastic material. Imd is made of in-mold decorative plastic, also known as paint-free plastic. The English name is In-Mold Decoration. It is a popular surface decoration technology in the world. The surface hardened transparent film, the middle printed pattern layer, the back injection layer and the middle of the ink make the product friction-resistant, prevent surface scratches, and keep the color bright for a long time. Imd in-mold decoration can replace many traditional processes, such as thermal transfer, spraying, printing, electroplating and other appearance decoration methods.
IMD is a popular surface decoration technology in the world at present, which has obvious advantages in replacing traditional technology in a wide range of applications. It is mainly used for surface decoration and function panels of household appliances, window lenses and housings of mobile phones and digital 3C products, protective covers of various brands of mobile phones and headphones, automobile interiors and dashboards and signs, medical instruments and testing instruments, cosmetics and other fields. Especially related products such as multicolor images and backlights.
Advantages of IMD
IMD technology can save the cost of reprocessing, which is very attractive to the automobile industry. Venkata-krishnan Umamaheswaran, production manager of lexan SLX (a polycarbonate polymer) at GE Plastics, said, "Paint is the most expensive thing in a car. The paint production line is the largest investment in the automobile assembly workshop, which will occupy half of the workshop area and produce more than 1500 tons of VOCs (volatile organic compounds) a year. "
The advantages of imd technology include: low rejection rate; The molding and decoration of parts can be completed in the same place; Better recyclability. IMD technology can obtain Class A surface without flow marks, which will not cause "in-mold color retention" like flow marks. However, if the part itself has many holes and must be decorated after demoulding, the economic benefits of IMD technology will be greatly reduced.
