Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of premium building materials, high-density polyethylene (HDPE) systems, PVC/UPVC pipe fittings, and high-precision injection moulds. As an established pioneer, Ehao Plastic Group stands as a recognized leader of PVC/UPVC ball valves in the domestic market in China.
Since our inception, our technological breakthroughs have been backed by the research of the Chinese Academy of Sciences and Zhejiang University. By introducing world-class computer automatic injection molding machines and production lines from Germany, we ensure our processing tolerances meet molecular precision.
Every single pipe and fitting undergoes 26 steps of rigorous scientific testing to ensure a 100% ex-factory pass rate. Our engineering indexes fully comply with international DIN 8077 and DIN 8078 standards, securing top-tier durability across all worldwide infrastructure applications.

Why modern global piping enterprises source from China: Combining advanced scale economics, rigorous custom mold design, and world-class raw material compounding.
Our dedicated mold manufacturing division handles custom designs, sample modifications, and structural blueprinting. We rapidly translate engineering requirements into functional prototypes using advanced CNC machines and injection molding capabilities.
Deploying German-designed extrusion and automated computer injection lines guarantees precise dimensional consistency. This minimizes wall-thickness deviations, ensures smooth inner walls to decrease fluid resistance, and prevents structural failure.
Our strict QC process evaluates 26 quality benchmarks, covering raw material melt index checking, long-term hydrostatic testing, heat regression, and visual surface consistency. This ensures structural integrity for pipeline lifespans of over 50 years.
Infrastructure projects require reliable polymer piping systems that meet local regulations. Ehao Plastic Group supports international buyers by offering products that meet strict mechanical and chemical standards.
Whether dealing with the high-performance demands of European district energy pipelines or chemical resistance requirements in North American processing facilities, our HDPE, PVC, and PP piping products align with standard regulations. Our systems are engineered using PE100 resins to ensure resistance to environmental stress cracking and to withstand high operational pressures.
We work with distributors and engineering consultants worldwide, providing product documentation, custom pressure ratings, and certified test reports for local projects.
Our products match standards like DIN 8077/8078 and ISO 4427. This ensures they meet global requirements for drinking water safety, dimensional tolerances, and high-temperature performance.
Located near major shipping ports, we offer flexible shipping options (FOB, CIF, CFR) and provide structured documents, custom labeling, and strong packaging for safe ocean freight delivery.
From modern homes to large agricultural and commercial projects, our piping products are designed to deliver reliable fluid transport.
The piping industry is shifting toward smart management, reduced carbon footprints, and improved material properties. Ehao Group designs products to meet these evolving requirements.
Modern projects require lightweight, long-lasting alternatives to metal systems. High-density polyethylene (HDPE) and structured vinyl polymers (PVC-U) resist scaling, chemical corrosion, and seismic activity.
Sustainable manufacturing is also key. We use clean, modern processing systems that recycle raw scrap and focus on leak-proof joints to conserve water in distribution networks.
We continue to research high-molecular-weight resins to handle higher pressures and temperatures, expanding where these systems can be applied.
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits.
