Description

Technical Field

[0001] The utility model relates to the technical field of crayon production, in particular to a crayon rapid prototyping mechanism. Background Art

[0002] Crayons are pens made by mixing pigment into wax. As a commonly used paintbrush, crayons are an ideal tool for children to learn color painting. Some painters also use them for sketching and color recording.

[0003] The main raw materials of crayons are paraffin, ozokerite, pigments, special polymer materials and other filling materials. When producing crayons, the raw materials need to be mixed together, heated to a certain temperature and stirred evenly, and then the hot solution is introduced into a crayon mold.
