Out-Mold Decoration
What is dry film coating?
The auto industry is currently undergoing a period of major change due to the global shift to carbon neutrality. In line with the CO₂ emission reduction targets of auto manufacturers, we are taking on the challenge of technological development and innovation in the painting process to achieve carbon neutrality in paint shop. As one of our efforts, we are advancing production technology innovations from wet painting to dry film coating. Applying protective & decorative film instead of conventional spray painting (wet painting) is a new method that can dry the process and reduce environmental impact.
What is OMD and IMD?
There are four methods for car exterior film decoration:
OMD (out-mold decoration), in which the film is laminated or transferred to the molded product afterwards,
and IMD (in-mold decoration) in which the film is pasted or transferred at the same time as resin injection molding.
We can propose the most suitable method and automated process line depending on the material, shape, decoration range, and production capacity of the molded product.
- Want to prevent air pollution
- Want to reduce CO2 and enhance energy efficiency
- Want to build comfortable spaces
- Want to make the best use of limited spaces
- Want to heighten equipment efficiency and paint quality
- Want to improve labor environments and achieve automation
Overview
The dry decoration line is a line that transfers parts (bumpers, etc.) brought from the previous process onto pallets on a conveyor, and automatically decorates, finishes, and inspects them at each process installed in a clean room.
The parts on pallet are first cleaned of debris and then applied with a film using vacuum-pressure technology. (Depending on the layer structure and specifications of the film, a curing process such as UV irradiation is performed after the film is applied.) In the next process, the film is trimmed and finished, and the trimmed scraps of film are removed. Finally, the film-decorated part is inspected and then transported to the assembly process. After the product has been unloaded, the pallet is returned to the loading location through the return line.

Features
The Dry Decoration system is capable of applying films on large three-dimensional exterior parts such as bumpers in a continuous line, and is compatible with resin and metal substrate parts. By adopting a dry decoration line, it is possible to significantly reduce CO2 and energy consumption compared to conventional wet painting. Since there is no need for large equipment such as the spray booth, air conditioning, drying oven, drainage equipment, paint circulation equipment, etc. required for wet painting, equipment costs and installation space can be reduced.
Another major feature is that the film's possibilities for design (patterns, hilt,illumination ) and functionality (solar cells, heat shielding) make it possible to create applications that are not possible with conventional coatings.
