This is out mold decoration (OMD) using vacuum pressure air.

NATS (air transfer) refers to a three-dimensional decoration technology that allows for the wrinkle-free application of pre-printed films (transfer films or laminate films) onto products with three-dimensional shapes (such as plastic, metal, and glass) by adding heated steam (super steam) to vacuum or pressure techniques in post-processing. This technology has established stable production. There are various names for three-dimensional decoration technology, but OMD (Out Mold Decoration) is the general term, which is further divided into OMR (Out Mold Release: transfer) and OML (Out Mold Laminate: laminate). In recent years, as global efforts towards carbon neutrality have progressed, there has been increasing attention on the transition from wet methods to dry methods (OMD technology).

basic information

1. Achieving improved adhesion by utilizing four types of heat sources ○ By adopting short-wavelength near-infrared heaters, the temperature difference on the front and back surfaces of the decorative film can be minimized, allowing for uniform heating. The temperature of the adhesive layer can be raised without applying thermal stress. ○ The use of superheated steam ensures that heat is evenly transmitted to the top, sides, and back of the product, significantly improving adhesion issues at the product edges. ○ The adoption of heaters on the inner surfaces of the chamber stabilizes the temperature within the chamber. ○ The use of line heaters prevents temperature drops of the superheated steam and enhances the effects of thermal pressure. 2. Target areas (Advantages of transfer) ○ Easy expansion to fitting parts. Since there is no need to consider the thickness of the film (approximately 20μ) from the design stage, components made of material, painted products, and transfer decorations (OMR) can be used with a common mold. ○ Easy expansion to perforated parts. Since the transfer adheres only to the areas that come into contact with the resin, decoration on perforated parts such as speakers or computer keyboards is easy, and trimming is unnecessary. ○ Possible redesign of existing molded products. With a film thickness of about 20μ, which is nearly the same as that of paint, there is no need to create a new mold, allowing for design changes.

Applications/Examples of results

It is widely adopted in automotive parts (interior and exterior) and home appliances. By utilizing the surface texture (tactile feel), which is the greatest feature of OMD technology, there has been an increase in products that create a sense of authenticity that was difficult to express conventionally. (Examples of adoption) - Automotive parts (interior) - Home appliances (ion generators, intercoms, etc.) - Electronic devices (laptops, hard disk enclosures, etc.) - Supply items (contact cases, etc.)
