The plastic formwork includes a main member made of polypropylene, stone powder, flame retardant, and reinforcing agent mixed together, where the main member has a number of channels inside and the channels are sealed by caps. To produce the plastic formwork, polypropylene, stone powder, flame retardant, and reinforcing agent are stirred, heated, and melted together, and the mixture is driven through a mesh forming machine to produce the main member. Finally, caps are attached to the main member to seal the channels. The manufacturing process allows convenient, precise, and uniform addition of materials, thereby improving production efficiency and product stability. The formwork provides fire retardation, heat isolation, sound proof, water tightness, and reusability. Additionally, cement paste is prevented from flowing into the main member, thereby avoiding the breeding of bugs and molds.
