Engineered from premium PVC, UPVC, PP, and PC compounds. Molded using advanced German computer-automated technologies for maximum physical stability and chemical resistance.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, high-durability pipe fittings, and injection moulds. Ehao Plastic Group stands as an undisputed leader in the manufacturing of PVC/UPVC ball valves within the domestic market in China. Since our inception, we have aligned our technical research with national scientific bodies, receiving critical technological guidance from the Chinese Academy of Sciences and Zhejiang University.
To guarantee that our products withstand rigorous pressure and fluid conditions, we introduced fully automated production lines and computer-controlled automatic injection molding machines imported directly from Germany. Through these precision machines, Ehao products are validated by 26 steps of rigorous scientific testing to secure a 100% ex-factory pass rate. The technical indexes of our outputs strictly accord with DIN8077 and DIN8078 international standards, scaling to world-class manufacturing heights.
Our operation is underpinned by the Ehao core philosophy: “honest, dedicated, innovation and return”. We adopt the holistic business paradigm of quality for survival, science and technology for progress, modern management for profitability, and unparalleled service for credit.
Modern injection molding requires an optimal convergence of clamping tonnage, plasticizing screw geometries, energy recovery systems, and high-response control loops. As industrial suppliers, Ehao ensures its partners have access to the optimal class of machinery for heavy-duty polymer processing.
Balancing energy efficiency with brute clamping force. Incorporates internal gear pumps driven by permanent magnet synchronous servo motors. Delivers fast response, high accuracy (within ±0.1% repeatability), and up to 60% energy savings compared to conventional throttling hydraulic setups.
Driven exclusively by independent servo motors for injection, plastication, clamping, and ejection. Ideal for cleanroom environments and medical/high-precision applications where zero hydraulic oil contamination is required. Eliminates hydraulic drift issues across varying ambient temperatures.
Employs high-speed electric injection units coupled with powerful hydraulic clamping systems. Allows the molding of compound designs, co-injected components, and thick-walled valves with rapid cooling cycles and optimized material distribution parameters.

Ehao’s manufacturing capability translates directly to real-world installations. By optimizing our molding machines for specific material characteristics, we support infrastructure pipelines across critical industries.
Modern living environments demand toxicity-free, highly aesthetic, and leak-proof distribution systems. Ehao’s PP and PVC water drinking taps and plumbing fittings are manufactured using high-flow, polished injection molds to ensure mirror-smooth interior paths. This eliminates biofilm adhesion, prevents pressure drops, and coordinates with residential interior configurations.
Outdoor agricultural installations are subject to thermal cycles, abrasive soil chemistries, and heavy UV exposure. Ehao's compact octagonal ball valves and garden bibcocks are reinforced with UV stabilizers and high-tensile engineering plastics. The resulting components resist environmental stress cracking and prevent fluid leaks in high-acreage agricultural networks.
Aquaculture operations require non-corrosive, non-toxic water circulation networks. Metal components introduce heavy-metal oxides that disrupt water biochemistry. Ehao’s double-union UPVC ball valves provide chemical inertness, high flow coefficients, and smooth manual actuation, securing biological safety in large-scale aquacultural environments.
Subterranean and structural municipal systems demand a service lifetime of up to 50 years under dynamic load conditions. Our injection-molded PVC fittings exhibit robust structural integrity, absorbing shear stresses and earth settlement pressure. Strict alignment with international standards prevents joint fatigue in critical urban drainage infrastructure.
Ehao’s manufacturing facility represents the peak of China's localized supply chain capability. By integrating direct structural materials supply, high-tolerance tooling centers, and high-performance injection machines under a centralized management execution system (MES), we minimize lead times while optimizing material yields.
This localized cluster efficiency allows us to hedge against global supply chain volatility, providing stable pricing structures and consistent product quality to our distribution partners in over 28 countries.
We understand that global infrastructure projects rely on verified compliance to national and international codes. Ehao guarantees that all materials and dimensions conform to strict quality guidelines.
Our polypropylene (PP) infrastructure components undergo strict quality checks to verify compliance with DIN 8077 (Dimensions of Polypropylene Pipes) and DIN 8078 (General Quality Requirements and Testing). This guarantees uniform wall thickness and excellent resistance to long-term hydrostatic stress at elevated operating temperatures.
Each product batch is subjected to a comprehensive quality control sequence including melt flow index (MFI) analysis, raw compound moisture content profiling, pressure burst evaluations, dimensional concentricity checking, and thermal reversion trials. We achieve a certified 100% ex-factory pass rate.
