Machining manufacture of color articles

Abstract

A process for preparing the color products (decoration, toy, food, etc) includes such steps as respectively heating the main raw material and pigments to fuse them, filling the fused main raw material in the main injector, filling the fused pigments in the color injectors, injecting the pigments in the slotted holes of die respectively, injecting the fused main raw material in its slotted holes in such manner that it is in contact with the ends of pigments, solidifying and demoulding.

Description

technical field [0001] The invention relates to a method for processing and manufacturing colored articles, which can produce articles with color changes and are not easy to decolorize and fade, and can be used in industries such as ornaments, toys, stationery and food. Background technique [0002] Existing methods of processing and manufacturing colored articles, especially for plastic ornaments, stationery, candy, chocolate and other foods, the method of producing color is mostly after the main body is formed, and then painted on the surface of the main body by coating and staining. Full color layers. For example, for plastic decorative pieces, the main body of the plastic is usually formed first, and the surface after forming is painted or dipped to produce modeling patterns or characters on the plastic; if chocolate is the main body, after the main body is formed, the surface is painted White, yellow, red, green. . . Such as icing or colored materials sticking patte...

AI Technical Summary

Problems solved by technology

[0004] 1. The color layer coated on the plastic surface is easy to wear and fall off

[0005] 2. When coating the color layer by dipping, the thickness of the color layer must be limited.

[0006] When too much material is used or when a three-dimensional effect is required, it is easy to cause the color material to flow out of the picture due to gravity, or due to the spread of surface tension, it is impossible to produce a more obvious and strong contour feeling

[0007] 3. When the main body is made of plastic, if a child bites it out of curiosity, the paint will easily fall off, causing the child to eat it by mistake

[0008] 4. When the main body is food, it is easy to cause the pattern and text formed by coating and painting to rub against the inner wall of the box due to the shaking during transportation, which greatly reduces the aesthetic feeling and economic value of the food

[0009] 5. Coated or dipped patterns and characters are not easy to locate on the main body, and are easy to be displaced or deformed, especially when the main body is food, it is often difficult to produce high-precision patterns and characters
