The "Three-Cavity Concrete Block Mould" is a specialized production tool that meets the modern construction industry's need for speed. These molds distinguish themselves from the standard "Concrete Block Mold" series by creating three cavities within concrete blocks (typically 150x400x200 mm). This three-hole structure ensures the final product is a "Lightweight Concrete Block" while also significantly improving the "Thermal Insulation Block" and "Sound Insulation Concrete"
