Substitute wood board In the glass fiber reinforced plastic industry, substitute wood is a relatively common mold board, which is made of polyester resin mixed with various fillers. The processed substitute wood can be cut into mold plates of various thicknesses to meet various mold manufacturing needs. Compared with the original wooden model, the surface of the substitute wood mold will be more durable and delicate, and can be used for mold manufacturing and trial production of a small number of samples.
According to the different polyester resins, the common substitute wood types include unsaturated resin, epoxy resin or polyurethane resin system substitute wood. The most used is unsaturated resin substitute wood, which is relatively economical and cheap. Epoxy or polyurethane substitute wood is generally used for prototype trial production of high-temperature parts, such as carbon fiber prototype production.
