Enamel technology originated in Germany. In 1924, the world's first rotocast machine was born in Germany and successfully made "chocolate rabbit".


There are many kinds of enamel dolls, from Hong Kong street culture to every doll in life. Enamel dolls are generally designed by well-known designers. A good enamel doll is a work of art and has become a popular toy with infinite vitality.

Enamel technology

gmtlight's design department has sorted out the basic knowledge about the enamel process for you:


1. Production process of enamel mold: drawing ----- mud sample ----- gypsum ----- wax sample ----- mold seed mold ----- mold seed coat ----- production mold ----- production skin.

2. The temperature of the enameling furnace is 250 ℃ ~ 280 ℃ for 2 minutes, and the temperature of the return furnace is about 100 ℃ for 10 minutes

3. The composition of the enamel material is as follows:


3-1. PVC fine powder 810

3-2. PVC coarse powder c65v

3-3. Plasticizer (white oil) (adjust the soft hardness of enamelled parts)

3-4. Hard oil txib

3-5. Hard oil 57 degrees

3-6. Heat resistant oil ed-s

3-7. Stabilizer ce-116

3-8. Release agent


Enamel products shall be free of impurities, raw rubber, bubbles, scratches, deformation and depression.


Many people think that enamel is the name of a material. Here, it is necessary to literacy. In fact, enamel is the name of a manufacturing process. Due to the special manufacturing process, some other things are added to the material, which makes everyone feel different from ordinary PVC toys, and then mistakenly believes that enamel is the name of the material.


The enameling process is to cover copper or other metals with similar properties on the surface of the prototype layer by layer, and then this layer of metal forms a simple metal mold. PVC paste resin and various plasticizers adjust the soft and hardness to form a latex state, then pour into the metal mold, bake the mold on the fire and rotate it constantly to make it heat evenly, Then take it out to cool it, open the mold and take out the product. Generally speaking, it mainly produces hollow molding products, and because it is made of PVC paste resin, the paste resin is more delicate than ordinary PVC resin. Compared with normal metal molds, this process has the advantages of low cost and convenient manufacture, but the disadvantage is that there is no pressure in the process, and the fluidity of paste PVC is not very good, resulting in the inability to make very fine and complex products.


So most enamel products are thick lines.
