Ehao Plastic Group stands as a premier high-tech private enterprise fully integrating research and development (R&D), precision mold design, polymer material synthesis, and high-volume production of architectural building materials, industrial pipe fittings, and custom plastic injection molds. Crucially, Ehao Plastic Group has established itself as an undisputed pioneer and market leader in high-performance PVC/UPVC and ABS ball valves within China's competitive domestic industrial sector.
Since our inception, our technological foundation has been fortified through ongoing strategic collaborative research partnerships with top-tier scientific institutions, including the Chinese Academy of Sciences (CAS) and Zhejiang University. By marrying academic polymer physics with field-tested manufacturing, we translate breakthrough materials science directly to the factory floor.
To maintain zero-defect tolerances, our state-of-the-art facilities feature fully automated, computer-controlled injection molding machinery imported directly from Germany. Every single component undergoes a rigorous 26-step scientific quality testing protocol, enforcing a strict 100% ex-factory pass rate. Our complete product lines rigorously meet international standards—including DIN8077 and DIN8078—matching world-class benchmarks for dimensional stability, pressure resistance, and structural integrity.
Co-engineered with researchers from Chinese Academy of Sciences and Zhejiang University for optimized polymer rheology and mechanical endurance.
Equipped with computer-controlled German injection molding systems ensuring microscopic repeatable accuracy across high-volume production runs.
Acrylonitrile Butadiene Styrene (ABS) is a premier terpolymer engineered by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The chemical synthesis grants ABS a unique trifecta of mechanical characteristics ideal for precision plastic injection molding:
Imparts exceptional chemical resistance, thermal stability, surface hardness, and resistance to environmental stress cracking.
Provides remarkable rubbery toughness, low-temperature ductility, and impact energy absorption even under sub-zero conditions.
Delivers high rigidity, excellent melt flowability during injection, high surface gloss, and exceptional dimensional fidelity.
Amorphous polymer matrix exhibiting a non-crystalline melting transition, minimizing anisotropic volumetric shrinkage during cooling.
