Wood mold is a relatively common way to open Plastic furniture mould. It is built with MDF supported by a bracket. After processing and surface treatment by CNC machine tools, it can be used to make FRP molds or prototype samples.

Due to the cnc cutting, the cutting texture on the surface of the wooden mold needs to be removed. If the treatment is improper or the effect is not good, these textures will be present on the final mold surface, which will require more time to process. Generally, the most commonly used method is to scrape putty or spray primer (polyester gel coat), and the two are used together. Putty is used to repair major defects, and then the entire polyester gel coat is sprayed to improve the surface treatment of the original mold. speed.

Personally, it is recommended to use together, which is more suitable for standardized glass fiber reinforced plastic mold manufacturing. Of course, you need to make an appropriate choice based on your specific situation.
