The primary purpose of the Rain Gutter Fitting Mould is to manufacture standardized, interchangeable gutter fittings with consistent dimensions, structure, and performance. These fittings are the "connective tissue" of gutter systems, and moulds ensure they meet industry standards (e.g., ASTM, DIN, or regional building codes) for compatibility and durability.

Its applications are tailored to diverse drainage needs, mainly including:

Residential gutter systems

Commercial building drainage

Custom architectural projects

High-volume manufacturing
