Conclusion

Silicone is an excellent material for mold making because it is durable, flexible, and easy to work with. It also has a very low shrinkage rate, which means that your mold will retain its shape and size over time.

Additionally, silicone molds can be used to cast a wide variety of materials, including metals, plastics, and waxes.
