The production methods of FRP trash cans can be divided into two types: open mold method and closed mold method.
The so-called mold opening method refers to glass fiber reinforced plastic products that can be produced with only one die or die when FRP is formed, and only need low pressure or even no pressure. This method belongs to the manual paste method, spray method , Vacuum bag method, pressurized bag method, autoclave method.
The products obtained by this method have only a smooth surface, but can be made into complex shapes, and large-scale FRP products can be produced.
The closed mold method adopts a pair of male and female molds, and adopts two methods: the modular method and the injection molding method. The sides of the FRP products obtained by this method are smooth, the surface is complete, and the products in the mold have good repeatability.
