Engineered to DIN8077/8078 Standards for Water Supply, Irrigation, and Industrial Systems
Ehao Plastic Group: Bridging Scientific R&D with Mass Production Excellence
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, high-precision pipe fittings, and custom injection moulds. Especially, Ehao Plastic Group is recognized as a dominant leader of PVC/UPVC ball valves in the domestic market in China. Since our inception, the company has been strongly supported by the Chinese Academy of Sciences and Zhejiang University in technological research and polymer development. This academic synergy enables us to innovate at the molecular level, upgrading polymer compounds to withstand extreme pressures and corrosive environments.
To maintain absolute manufacturing superiority, we have introduced state-of-the-art production lines and computer automatic injection molding machines directly from Germany. Every product manufactured in our facilities undergoes a rigorous 26-step scientific testing regimen under strict quality control conditions to guarantee a 100% ex-factory pass rate. The technical indexes of our products fully accord with DIN8077 and DIN8078 standards, reaching world-class structural and functional benchmarks.
By virtue of our comprehensive advantages—including major brand influence, excellent product quality, and distinct marketing strategies—our high-performance fluid handling products cover most provinces and cities in China and are exported to over 28 countries and regions, including Europe, America, and Southeast Asia. We continue to win the praise of domestic and foreign merchants alike.
In addition to catalog components, Ehao operates a dedicated mold-making division that designs and manufactures custom plastic moulds, supplying materials, custom samples, and tailored plastic products via extrusion and injection technologies. We can rapidly develop and manufacture new products according to customers' specific industrial requirements. We warmly welcome clients at home and abroad.
Providing custom plastics injection molded components for critical infrastructure and commercial projects
Providing lead-free, non-toxic water supply solutions. Our POM and PVC faucets, bibcocks, and fixtures ensure safe drinking water distribution while maintaining high aesthetic standards and ease of installation in residential piping layouts.
Robust compact ball valves and octagonal valves engineered to withstand UV exposure, dynamic pressure spikes, and particulate-heavy agricultural runoff. Perfect for modern drip irrigation and macro-distribution networks.
Designed for sensitive marine and freshwater environments. Ehao's pure-form polymer resins eliminate heavy metal leaching, ensuring bio-safety in commercial fish cultivation, breeding tanks, and water treatment loops.
Heavy-duty double union ball valves and thick-walled PVC pipes manufactured to resist concrete loads, soil shift, and chemical attack in industrial drainage, municipal sewage, and structural conduit installations.
Integrating Advanced Automation, Academy-Grade Chemistry, and Industrial Scale
Our factory floor represents the convergence of high-volume efficiency and precision tooling. By using computerized, automatic injection molding machinery sourced from Germany, we minimize dimensional variance to within micrometers. These systems continuously monitor temperature, injection speed, hold pressure, and cooling times in real time to prevent issues like knit lines, voids, or internal stress.
Our strategic collaborations with the Chinese Academy of Sciences and Zhejiang University keep us at the forefront of polymer modification. Our R&D team modifies standard PVC and UPVC compounds using targeted additives to increase impact strength, elevate thermal deflection thresholds, and optimize UV resistance.
Highly automated German injection molding machinery regulates cycle times and melt temperatures. This ensures uniform crystallization of polymers, resulting in high mechanical strength and consistent wall thickness.
Partnering with China's leading chemical engineering faculties allows us to incorporate stabilizers and impact modifiers into our raw materials, enhancing performance under high-pressure conditions.
Every production batch is tested across 26 points, including hydrostatic burst pressure, sustained high temperatures, dimensional tolerance audits, and structural stress tests.
Our production adheres strictly to DIN 8077 and DIN 8078 standards. Each batch is logged with production parameters and raw material source tracking, ensuring supply chain integrity.
How we are preparing for the next generation of plastic injection molding and smart fluid systems
As the requirements for global infrastructure evolve, Ehao is committed to a multi-phase technology roadmap centered on material optimization, smart manufacturing, and eco-friendly practices. We are investing in three key growth areas:
To meet global sustainability goals, Ehao's R&D department is testing bio-based PVC compounds and halogen-free stabilizers. These materials reduce the carbon footprint of production without compromising the mechanical strength, chemical resistance, or lifespan of our valves and fittings.
Industrial fluid networks are increasingly utilizing smaller, more complex control systems. By upgrading our tooling to support high-cavity, hot-runner molds with tolerances down to ±0.01mm, we can manufacture micro-valves and complex connectors that reduce cycle times and waste.
We are developing smart ball valve assemblies that incorporate electronic sensors. These units track pressure, temperature, and flow rate directly within the valve body, facilitating easy integration into modern industrial automation systems.
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits.
Streamlined engineering processes designed for international B2B buyers and global distributors
Ehao Plastic Group operates a dedicated, end-to-end OEM and ODM pipeline designed for global industrial buyers. We specialize in transforming engineering drawings into high-volume production runs.
Aligning with international standards for smooth integration into local markets
Managing global supply chains requires strict adherence to international standards. At Ehao, our products are engineered to align with local codes and regulations:
Expert answers regarding mold tooling, polymer chemistry, and wholesale sourcing processes
DIN 8077 (dimensions of polypropylene pipes) and DIN 8078 (general quality requirements and testing of PP pipes) ensure that the wall thicknesses, outer diameters, and pressure capabilities of piping components are tightly controlled. By manufacturing in accordance with these standards, Ehao guarantees that every pipe fitting and valve will integrate seamlessly into standard piping systems worldwide while tolerating design pressures and temperature fluctuations.
Our zero-leakage guarantee stems from our 26-step quality control protocol and precision-molded internal seals. Every valve undergoes hydrostatic and pneumatic pressure testing at the factory. Additionally, we use high-grade PTFE seats and double O-ring seals to maintain a bubble-tight seal over thousands of open-close cycles.
We support a wide array of thermoplastic materials including Polyvinyl Chloride (PVC), Unplasticized Polyvinyl Chloride (UPVC), Polypropylene (PP), Polyacetal (POM), Acrylonitrile Butadiene Styrene (ABS), and Polycarbonate (PC). This range allows us to match the right material properties—such as chemical resistance, tensile strength, or food-safety compliance—to your application.
Yes. Using advanced reverse engineering techniques and 3D laser scanners, we can generate high-precision digital CAD files directly from your physical samples. Our engineering team then optimizes these files for injection molding efficiency before producing the mold tooling.
