Wood grain transfer printing is primarily applied to steel fire doors or security doors, as a special treatment process on steel plates.

 

The general treatment process for steel fire doors is electrostatic powder coating, which utilizes the polarization effect of polar powder coating molecules under high electrostatic voltage. An electrostatic spray gun is used to apply synthetic polymer powder coatings, such as polyester, polyamide, or epoxy, onto the surface of the workpiece that has undergone pre-treatment (e.g., phosphating). The workpiece is then passed through a curing oven to form a durable and corrosion-resistant coating film.

using electrostatic powder coating surface treatment technology to create a coating layer that is robust, corrosion-resistant, and aesthetically pleasing. A variety of colors that closely match architectural decoration styles can be selected. Alternatively, pre-laminated steel plates with wood grain patterns can be directly used, along with various three-dimensional embossed designs.

 one is water decal transfer technology, and the other is hydrographic film transfer technology. The former is mainly used for transferring text and photographic patterns, while the latter is more inclined to achieve complete transfer across the entire product surface. Printing is a technical process that transfers the wood grain pattern from the printing plate to the substrate via transfer materials. It easily wraps around the product surface to form a graphic layer, giving the product a completely different appearance, as if it were painted. Hydrographic film transfer technology can apply colorful patterns to workpieces of any shape, solving the problem of printing on three-dimensional products for manufacturer

Vacuum wood grain laminating technology: After electrostatic spraying on metal products is completed, the wood grain is transferred to the workpiece surface through a heat transfer method. This technology ensures the wood grain does not fade easily, looks realistic, and enhances the product's grade. It is widely applicable to: aluminum alloy doors and windows, security doors, steel fire doors, steel-wood furniture, filing cabinets, computer casings, household appliances, metal accessories, and other high-temperature-resistant metal materials.
