Differential Pressure Overlay Decoration Machine (DOD)
01 Introduction to DOD Process
The Differential Pressure Overlay Decoration (DOD) machine, introduced by Dekuma, is a novel Out Mold Decoration (OMD) technology solution, extending from the In-Mold Decoration (IMD) process.
The DOD process utilizes heating, vacuum, and high-pressure gas to achieve surface coating or transfer printing, enabling a higher-quality 3D surface decoration technique. This process belongs to the three-dimensional appearance enhancement technology.
As an extension of IMD, it combines colors, textures, and tactile effects, seamlessly integrating printing technology, textures, and metallization properties. It can create more three-dimensional, highly complex 3D curved surface products with various achievable appearance effects, including metal brushing, wood grain, stone texture, leather, and more.
02 Key Features of DOD Process
The DOD process can be applied to decorate various material surfaces: plastics, glass, metals, wood, stones, etc. Due to the lower softening temperature of the film used in the manufacturing process compared to in-mold decoration, the tactile sensation is better preserved, making it less prone to weakening or disappearance. The touch has a noticeable relief, effectively solving the covering problems of complex products that cannot be handled manually and improving product yield.
03 Introduction to DOD Process Flow
The DOD equipment process involves heating the film material with an adhesive layer and then overlaying it onto the product surface using vacuum and atmospheric pressure, ensuring a tight fit.
The key manufacturing steps involve utilizing pressure differentials, including positioning, vacuuming, heating the film, and applying pressure. It requires six steps to mold and extract the product.
