Silicone mold is a special mold glue for making handicrafts. Silica gel is characterized by high temperature resistance, corrosion resistance, strong tear resistance and high simulation accuracy, and is a mold for making various handicrafts.
Resin mold
Resin usually refers to an organic polymer with softening or melting range after heating, which tends to flow under the action of external force after softening, and is solid, semi-solid and sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as raw material for processing plastic products is called resin. The main characteristics of resin mold are good fluidity and operability. 2%-3% curing agent is added at room temperature, which can be operated within 30 minutes and molded after 2-5 hours. It has the advantages of no deformation, high temperature resistance, acid and alkali resistance and no expansion.
The difference between silica gel mold and resin mold;
1. The prototype of silicone rubber mold is made by SLA, FDM, LOM or SLS, and then converted into silicone rubber mold. Two-component polyurethane is poured into the mold and cured. To the required part. Bridge formwork (bridge? Tool) usually refers to an epoxy resin mold that can be produced directly by injection molding.
2. Compared with the traditional injection mold, the cost of using epoxy resin mold is only a fraction of that of the traditional method, and the production cycle is also greatly shortened. ? The service life of the die is not as long as that of the steel die, but longer than that of the silica gel die, reaching 1000 ~ 5000 pieces, which can meet the needs of small and medium-sized batch production. Hard mold (hard? Tools) usually refers to steel molds, that is, indirectly manufacturing metal molds and directly processing metal molds with rapid prototyping.
Application:
According to the mould material, production cost, RP prototype material, production batch and mould precision requirements, various technological methods have been developed. At present, there are two kinds of rapid molding methods: indirect molding method and direct molding method. RP-based rapid modeling methods are mostly indirect modeling methods. According to the different materials, the molds produced by indirect molding method include soft mold, bridge mold and hard mold, generally referring to silicone mold, resin mold and steel mold.
Silicone molds are mainly used for toys, gifts, products with fine patterns, covering molds, pouring molds, making molds for glass crafts, lighting, candles, figures, making molds for large-scale products, cutting molds, reliefs, Buddha statues, craft gifts, sole models, pouring molds, and sand casting.
