First, at present, polyester resin is the main material for making human anatomical models. First, different parts are cast in different models, and branches are poured into mucous membranes of different parts. This is the skull membrane and this is the pericardium. Then, the two halves of the mold are tightly closed, and the mold is sent to the gas stove. The temperature is set at 225 degrees Celsius, the heat passes through the mold, and the tree value becomes evenly covered on the whole inner surface. You can leave the hospital in ten minutes 12 minutes.
Second, workers sprinkle water on it to cool down, then open the column mother and take out the warm cast sword, which is the outline of shoulders, muscles, heart, arms and legs. Workers put them on heat-resistant high wool to cool and shape them, and release the trapped air with needles to prevent the finished products from breaking. Then drill some holes into which nails can be inserted to assemble the whole model. The model of each part is drawn by hand to highlight the main features. The painter carefully drew the vein on this leg in blue and the nerve endings in yellow and red. Arteries and blood vessels and even toenails should be colored. Before assembly, workers must insert metal nails in each part, which can connect all parts with each other.
Third, the painter put the model in the heater for about 15 minutes, so that the plastic can soften after painting other parts, which makes it easier to combine. The worker fixes the head on the nail of the trunk, then puts the brain in the headband of the model, puts on the skull, and fixes the nail in the hole of the insert link part. Add muscles to the arm, including controlling the biceps and deltoid muscles of the hand. The deltoid muscle is the muscle on the flat joint that helps to lift the arm, and then fix the arm on the trunk. Each combined model can be disassembled. This full-scale human muscle model is 138 cm high, and there are 45 parts in it, all of which are constructed in proportion to the human body, thus making a human model.
