What are the emerging processes derived from the process of metal thermal transfer

Update:15 Sep 2020

1. In-mold decoration technology (IMD)

The in-mold decoration process is a plastic decoration technology that uses the temperature, pressure of plastic molding (including injection molding, blow molding) and a certain period of time to simultaneously attach functional layers, structural layers or decorative layers in the mold. In-mold decoration is generally divided into in-mold labeling (IML), in-mold transfer film (IMR), and in-mold coating (IMC). In-mold decoration technology, especially IML and IMR technology, has many advantages. It can effectively reduce product reprocessing procedures and cycles, solve multi-faceted, special-shaped surface and other decorative problems, improve product quality and grade, and have high automation and efficiency. , Environmental protection production and environmental protection use performance outstanding. In-mold decoration technology is mainly used for in-mold decoration of plastic products such as electronic products, room supplies, gifts, stationery, toys, handicrafts, etc.

2. Vacuum transfer process (TOM)

The vacuum transfer process is a technology that uses a thermoplastic film as a carrier and its variable characteristics of heat and external force to achieve profiling decoration on a formed workpiece through heating, pressure and a certain period of time. Vacuum transfer is also called three-dimensional transfer process or high-pressure transfer process, and its advantage is to solve the problem of positioning and decoration of workpieces with large different shapes. The vacuum transfer printing process can achieve both transfer method decoration and overlying legal decoration. Its process and application have just started in China, and it has received very wide attention, and there has been a trend of using its process characteristics to extend the process. Its process market The potential is huge. The vacuum transfer process is mainly used in shoes, boutiques, building materials, automotive interiors, electrical panels, etc.

3. Thermal sublimation (air dyeing) process (Thermal Dye)

Dye sublimation is a decorative technology that uses the sublimation characteristics of disperse dyes (inks) to transfer disperse dyes to the substrate through a substrate carrier under certain conditions of temperature, time and pressure. Dye-sublimation technology was very common in fabric transfer in the early days. With the promotion of its application, the transfer of decorative wood grain on various sprayed metal profiles has begun to rise in recent years, and is favored by home decoration. Dye sublimation (gas dyeing) process is mainly used for transfer decoration of metal surface after spraying, baking varnish, electrophoresis, etc.

4. Water Transfer Printing Technique

There are two types of water transfer printing technology, one is water mark transfer technology, and the other is water coating transfer technology. The former mainly completes the transfer of partial text and pictorial patterns of the workpiece, while the latter tends to be a complete transfer on the entire product surface. Here we focus on the water coating transfer technology: use a polymer film that is easy to dissolve in water to carry images and texts. Because the water coating film has better tension, the images and texts on the film are under the action of water pressure and activator. It is easy to wrap around the surface of the product to form a graphic layer, and can be combined with spray paint to form matte, bright and other texture effects. Covering transfer technology can cover color graphics (such as leather, wood, jade, marble, etc.) on workpieces of any shape, and at the same time, it can avoid the common position and damage in general workpiece printing The product surface and its integrity solve the problem of three-dimensional product printing for customers. The water coating process is mainly used in automotive supplies, electronic products, room supplies, gifts, stationery, toys, handicrafts, indoor building materials, etc.
