Plaster turnover mould making process

The manufacturing process of gypsum turnover mould is as follows:

Material preparation: gypsum mud, little love, round stick, ruler, etc.

1. First, press the prepared gypsum mud into a mud board.

2. Put Xiao Ai flat on it and clean up the mud.

3. Take a piece of plastic and roll it into a bucket shape, stick it firmly with tape paper and insert it directly on the clay board.

4. Then seal the gap between the plastic bucket and the mud board with some gypsum mud to prevent the gypsum mud from leaking out. This step is very important and can't be sloppy at all. Otherwise, slurry leakage will be very troublesome.

5. Then measure the volume of the cylinder with a ruler and calculate how much gypsum powder and water are needed.

6. Gradually add gypsum powder to the water, and be sure to remember to add water before adding powder. After standing for tens of seconds, you can slowly stir gypsum powder and water in one direction with your fingers until they are mixed into emulsion.

7. Pour the mixed gypsum slurry into the drum, gently stir it with your fingers in the drum to prevent bubbles from appearing in the slurry, shake the board to let the bubbles in the gypsum slurry escape, and remove the small bubbles with your fingers.

8. After a few hours, the plaster can be opened after it is formed. After opening, some gypsum may overflow, which can be trimmed with suitable tools.

9. Little love has a small hat behind it. Can be taken out and demoulded with a needle through the hole.

10, the last step is to polish the gypsum edge with a planer, and the small gypsum will turn over.

Brief introduction of gypsum mould turnover;

Gypsum turnover is a method of making models or sculptures. It is usually divided into two steps: first, the surface of the prototype is coated with gypsum slurry to make a gypsum model; Secondly, the prototype and gypsum model are inverted together, and the prototype is removed, and then gypsum or other materials are filled in the model to make an accurate replica of the sculpture or model.

This technology is widely used in art, sculpture, fashion models and other industries. In these industries, gypsum turnover is usually a low-cost and high-quality production method. In addition, this technology is often used in scientific research to make experimental models, so that researchers can better understand and analyze physiological, mechanical, chemical and other systems.

It should be noted that when using this technology, it is necessary to use high-temperature resistant gypsum to ensure that the model will not be deformed or degraded over time. In addition, attention should be paid to safety when making plaster models to avoid gypsum invading eyes, mouth or other human parts.
