1. Plaster mold
It is generally used for the production of master molds for large-scale Fiberglass sculpture products because the gypsum mold has high heat resistance, the small thermal conductivity of the material, good copy ability, and low price. Therefore, some simple reliefs, small and medium-sized round sculptures, etc. use more plaster molds. However, everyone knows that the gypsum product is fragile, the plaster mold is not durable, and the drying is slow. It should be placed in a stable place to avoid damage.
2, rubber mold
It is generally used for the fabrication of a complex embossing, round carving, and a certain part. It is made of two materials, silicone rubber, and polyurethane resin. The rubber mold has a certain softness, so it must be combined with other materials. It can be used, generally used with plaster molds. For example, lions, dragons and other animal sculptures mostly use this mold.
3, concrete mold
Concrete molds are often used for wire-type and reusable applications, such as spiral, wavy, circular, arched or three-dimensional grooved goods. The cost is low and the rigidity is good. The brick head can be used as a base, and then covered with cement mortar, polished, putty, and then polished, polished, painted and the like. This cement mold can be directly used to produce finished Fiberglass, and can also be used as a master mold for reversing Fiberglass molds. The cement mold is dry and slow, and even under normal conditions, it takes more than a week to paint and paint.
4, metal mold
Metal molds, especially steel molds, are commonly used for molded goods with small dimensions and large batch sizes. For example, stainless steel plates with smooth appearance when making Fiberglass flat plates; angle steels and channel steels for outer profiles. Since the molded product is not only pressurized, it is heated. There are also large-scale goods for an unobtrusive appearance.
