Abstract

The invention relates to an in-die decoration printing method, which comprises the following steps. Firstly, a pattern thin film and a die assembly are provided, the pattern thin film is provided with a presetting pattern, the die assembly is provided with a die cavity, a plurality of air inlets and a pouring hole, wherein, the air inlets and the pouring hole are communicated with the die cavity, and the pattern thin film is arranged on the wall of the die assembly. In succession, the plastic self pouring hole is injected in the die cavity. Later, air flow is fetched in from the air inlet, to lead plastic to being extruded to the pattern thin film by the air flow, and lead the pattern thin film to being attached on the inner wall of the die assembly flatly.

Description

technical field [0001] The present invention relates to a printing method, and in particular to an in-mold decoration (InMold Decoration, IMD) printing method. Background technique [0002] Generally speaking, the in-mold decoration printing method is applied to the decoration processing of plastic casings. For example, the patterned plastic case of a mobile phone is a product produced by the in-mold decoration printing method. Please refer to Figure 1A to Figure 1C , Figure 1A to Figure 1C It is a process sectional view of a known in-mold decoration printing method. The in-mold decoration printing method of known technology comprises the following steps: at first, as Figure 1A As shown, a patterned film 110 is disposed on an inner wall 120 a of a mold 120 , wherein the patterned film 110 has an ink pattern 112 . Next, if Figure 1B As shown, the plastic 130 is injected from a sprue 124 of the mold 120 such that the plastic 130 fills the mold cavity 122 . After the p...
