A plastic chamfer mould, often called a filter plastic, is a multipurpose instrument that is used in concrete construction projects to produce exact chamfer edges. This mold, which is made of flexible solid plastic, is intended to create a 45-degree chamfer in concrete surfaces, guaranteeing smooth and even edges.

When using the fillet mould, it is typically nailed onto formwork, allowing it to create chamfer edges for panels or columns during the concrete pouring process. By securely attaching the mould to the formwork, contractors can achieve consistent and professional-looking chamfer edges that enhance the overall aesthetic appeal of the concrete structure.

In addition to its primary use for creating chamfer edges, fillet moulds can also be employed to produce architectural grooves in the panel face, adding decorative elements to the concrete surface. This versatility makes fillet moulds indispensable tools for architects, contractors, and builders seeking to achieve precision and quality in their concrete construction projects.
