What is the classification of Fiberglass sculpture mold materials

1. Gypsum mold
The mold cavity made of gypsum material is also called the broken mold method. However, the gypsum material is low in strength and easily deformed when placed for a long time.2, silicone rubber mold
The mold cavity made of silicone rubber material is also called the soft mold method. The silicone rubber material is in a fluid state before use, and has good fluidity and filling properties. After the preparation, the rubber elastomer is formed by a crosslinking reaction and can have a large elastic deformation. The cross-linked silicone rubber has good sealing properties and does not bond with the original mold and the glass fiber reinforced plastic. The surface layer material used for the Fiberglass sculpture mold can not only reproduce the shape of the work with high quality but also ensure smooth demolding. However, the silicone rubber crosslinked body is easily deformed, and when used as a mold, a support carrier is required. It can be used as a carrier material for the mold by utilizing the characteristics of Fiberglass easy forming.
3, Fiberglass mold
The mold cavity made of Fiberglass sculpture material is also called the hard mold method. That is to say, the Fiberglass sculpture is turned on the Fiberglass mold, and the Fiberglass mold is generally formed by a hand lay-up method, and the molding line should be designed before the production.
