The shrinkage rate of mold silicone is usually between 1% and 3%, depending on the formula and usage method of the silicone. During the production process, silicone molds may experience a certain degree of shrinkage due to the evaporation and solidification of volatile substances, which is a normal phenomenon. High quality silicone molds will undergo a period of curing and maturation after production, and the shrinkage rate will gradually stabilize at a fixed value.
Silicone mold is a commonly used material for making molds with complex shapes, which has excellent elasticity and high temperature resistance. When making silicone molds, the first step is to mix the silicone evenly and pour it into the mold prototype, and then wait for the silicone to solidify and form. During the curing process, the mold will undergo a certain degree of shrinkage because the volatile substances in the silicone will gradually evaporate, resulting in a decrease in the volume of the mold.
In order to reduce the shrinkage rate of the mold, some measures can be taken when making silicone molds, such as avoiding the generation of bubbles when mixing silicone and maintaining constant temperature and humidity during the mold curing process. In addition, choosing high-quality silicone raw materials can effectively reduce the shrinkage rate of molds.
In practical use, pre made silicone molds can be used to make various complex shaped products, such as handicrafts, toys, models, etc. Silicone molds have a long service life and good replication effect, and are widely used in handmade and industrial production fields.
Overall, the shrinkage rate of silicone molds is an important parameter that needs to be taken into account during the manufacturing process. Reasonable control of shrinkage rate can ensure the quality and effectiveness of the molds. Through scientific formulas and manufacturing processes, the shrinkage rate of silicone molds can be effectively reduced, and the stability and reliability of the molds can be improved.
