How to draw a mini plaster doll?

The plaster doll paints on the plaster blank with a paint tray and a paint pen (wide pen and thin pen Gou Xianbi).

Gypsum doll belongs to model gypsum, which is made of α -type calcium sulfate hemihydrate and appropriate pigments and other additives. Gypsum mould is a traditional mould used for a long time in industrial production. Mould is the basic material of casting production, which has become an important factor restricting casting modeling, uniformity, labor productivity and production cost.

Gypsum mold refers to the mold used to make gypsum images, which can be roughly divided into resin mold and latex mold.

Gypsum mould is a traditional mould used for a long time in industrial production. Mould is the basic material of casting production, which has become an important factor restricting casting modeling, uniformity, labor productivity and production cost.

There are many factors that affect the quality of gypsum mold, such as ore type and its structural characteristics, dehydration mode and temperature, calcination time, particle size, pH value of water, the ratio of gypsum to water, mold quality, mold release agent quality, pouring technology and operation technology, and external environment, which directly or indirectly affect the quality of mold, so there are various ways to improve the quality of mold.

It is found that the performance of gypsum hemihydrate, mold quality and pouring technology are important factors affecting gypsum mold, so the improvement work is carried out from these three aspects.
