First-generation products: Utilized casting technology (before 2010), resulting in high material waste (20%-30%) and excessive porosity.
Second-generation innovation: In 2015, stamping and welding technology was introduced, applying the elliptical-to-circular hole conversion process to tee production, increasing material utilization to 85%.
Third-generation breakthrough: In 2020, combining a regular polygonal structure with a snap-fit system significantly reduced installation time for pipe fittings.
