Summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, provide a kind of can be at the section bar of different shape surface bat printing, make on each male and fomale(M﹠F) of section bar all can bat printing on a kind of section bar thermal transfer printing technology of required pattern.

The objective of the invention is to be achieved by the following scheme: these process using following steps:

Step 1: the lacquer and solidifying of resinizing on the required decorative cover of section bar earlier, used section bar must heatproofs more than 150 ℃;

Step 2: use the thermal transfer printing technology that does not have China ink and routine of distillation pigment, required pattern is printed on the material of paper or film shape by printing;

Step 3: paper that prints pattern or film bag are attached on the section bar decorative cover that coats resin, put well stand-by;

Step 4: get the powdery of the temperature storage of conducting heat, granular material be placed on be heated in the heater temperature required stand-by.

Step 5: will wrap the section bar material that posts and flood reason fully, through vibration required decorative cover is contacted with the every bit of thermal transfer printing paper or film and heat-transfer matcrial full and uniformly and be one, decorative cover characteristics according to required thermal transfer printing material, under 150 ℃ of-250 ℃ of temperature, the insulation 10 seconds of conducting heat did not wait to 30 minutes, treat that thermal transfer printing finishes after, section bar is taken out, and the paper or the film avulsion on bag subsides surface, the complete pattern of required ornament materials or product promptly forms.

The present invention is compared with the prior art: adopted the method for flowing or blow over and cover completely powder, granular material as thermal conductor, can make each male and fomale(M﹠F) of section bar and bag post thermal transfer printing paper or film and heat-transfer matcrial tight connecting, form the Trinity, no matter the surface of many complicated shapes all can bat printing on required pattern, and pattern adhesive force is very strong, and outward appearance is clear attractive in appearance.
