Precision injection-molded components engineered for heavy-duty industrial and residential applications.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of premium building materials, pipe fittings, and high-complexity injection moulds. As a domestic market leader of PVC/UPVC ball valves in China, we have continuously set industrial benchmarks for durability and performance.
Since our inception, our technological advancement has been supported by leading institutions such as the Chinese Academy of Sciences and Zhe浙江 University. We combine advanced polymers chemistry with automated precision to deliver global-standard fluid control solutions. Our production ecosystem operates German computer automatic injection molding machines to achieve unrivaled production consistency.
Delivering precision engineering and high corrosion resistance across dynamic global industries.
How we continuously redefine high-precision injection molding workflows for global partners.
Leveraging thermodynamic analysis software to simulate polymer behaviors, eliminating defects such as sink marks and weld lines prior to tool manufacturing.
Integrating high-impact modifications and premium ultraviolet stabilizers to extend the service life of UPVC/PP pipelines under harsh environmental stresses.
Upgrading computerized German injection lines with real-time pressure transducers and automated camera sorting to enforce a true 100% ex-factory pass rate.
Operating in Zhejiang, China’s industrial plastics cluster, Ehao Plastic Group delivers unmatched logistical agility. Our factories boast deep integration with raw material suppliers, enabling rapid feedstock acquisition and mitigating cost volatility for international buyers.
Our infrastructure partners with method-based machine tools every step of the way—assisting partners from initial custom component layout, through pilot prototyping, to highly scaleable, cost-effective wholesale production. Our proximity to deepwater international shipping ports ensures reliable and timely global distribution.
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits.
Providing technical answers for engineers, procurement officers, and international distributors.
Ehao executes a comprehensive 26-step scientific testing regimen. Our high-precision injection components align with DIN 8077 and DIN 8078 metrics. This guarantees that all plumbing interfaces, compact ball valves, and industrial connectors sustain design pressure limits under rigorous environmental stresses.
We maintain full in-house tooling workshops. Clients supply sketches, 3D CAD files, or physical parts. Our technical group performs mold flow calculations and designs customized multi-cavity tooling systems. We run pilot trials on our German automated machinery before transitioning to full wholesale production.
We primary injection-mold UPVC, PP, ABS, and PC resins. Each compound features dedicated modifiers, such as anti-UV stabilizers and high-impact modifiers, tailored to ensure long-term stability in harsh irrigation and building projects.
Every single compact ball valve is pressure-tested manually and automatically before shipping. By combining high-precision injection tooling with premium elastomeric gaskets (EPDM/PTFE), we secure a hermetic seal that remains responsive and leak-free through thousands of operation cycles.
Mold design and manufacturing typically require 25 to 35 days. After sample validation, batch manufacturing depends on volume, but generally runs between 15 to 25 days. Our streamlined supply chain in China assures rapid turnaround cycles compared to European operations.
Our double-union and compact valves are popular in South America, North America, Southeast Asia, and Europe. Their precise thread and socket sizes easily adapt to global localized distribution requirements and municipal plumbing codes.
Ensure absolute pressure containment and chemical inertness in your fluid transportation networks.
