Ehao Plastic Group operates as a leading high-tech private enterprise, positioning itself at the absolute forefront of research, development, and manufacturing of custom building materials, fluid control components, plastic pipe fittings, and advanced injection molds. Most notably, the group has established a dominant market leadership within China for PVC/UPVC ball valves and micro-tolerance injection molding configurations.
Since our inception, our technological progress has been continuously bolstered by collaborative frameworks alongside the Chinese Academy of Sciences and Zhejiang University. By bridging the gap between state-of-the-art polymer science and industrial application, we have successfully developed high-performance systems suitable for heavy industrial processing. To guarantee mechanical absolute consistency, Ehao imported automated computer-driven injection molding lines directly from Germany, integrating multi-axis robotic handlers and precision dosing interfaces that form the baseline of our LSR (Liquid Silicone Rubber) injection molding systems.
Every single product manufactured in our facility undergoes a rigorous 26-step scientific testing protocol, managed via an independent Quality Assurance (QA) unit. This relentless attention to detail ensures a flawless 100% ex-factory pass rate. The technical specifications of our engineering outputs fully align with globally recognized DIN8077 and DIN8078 standards, securing our position as a reliable supplier for international engineering consortiums.
Global medical technology buyers demand LSR systems capable of operations within Class 10,000 cleanrooms, satisfying strict ISO 13485 regulations and FDA biological compatibility indicators.
Engineers optimizing EV battery packs, sensor seals, and powertrain gaskets require LSR machinery offering micro-precision dosage controls and high-velocity injection profiles.
Global municipal construction projects depend on highly stable structural piping systems. The integration of high-grade gaskets with heavy-duty PVC valves guarantees zero-leak lifespans.
Industrial procurement structures are undergoing a massive transition. Global buyers are moving away from traditional, fragmented machinery acquisition models and prioritizing integrated manufacturing systems. Today's procurement manager focuses heavily on the Total Cost of Ownership (TCO), which involves evaluating the mechanical durability of molds, raw material conservation through cold-runner technologies, and energy consumption ratios of servo-driven clamp designs. Ehao satisfies these specific demands by providing single-source solution options: combining highly specialized German machine layouts with in-house custom mold development.
Processing Liquid Silicone Rubber introduces strict mechanical challenges due to its low viscosity and high curing temperatures. Standard thermoplastic molds fail to manage these requirements, making specialized tooling and advanced machine dynamics absolutely necessary. Below is Ehao's progressive technological development plan:
To eliminate waste in high-volume production runs, our LSR machines integrate direct pneumatic needle-valve shutoff cold runner devices. These systems cool the material right up to the cavity gate, optimizing cure rates and saving significant raw material expenses over long runs.
Leveraging advanced German computer controller designs, Ehao's injection molding units feature screw options optimized for silicone delivery. These setups prevent air pockets and material degradation, ensuring uniform part densities in every shot.
The manufacturing industry increasingly requires components combining rigid plastics (like glass-filled nylon or PBT) directly with soft LSR sealings. Ehao's ongoing R&D efforts are focused on developing multi-component molding processes that eliminate secondary manual assembly steps, dramatically improving seal integrity.

For heavy industry applications, material compliance is a safety priority. Products manufactured by Ehao fully align with the physical and chemical requirements of both DIN8077 and DIN8078. These European standards define critical dimensions, hydrostatic pressure thresholds, and chemical resistances for polypropylene and vinyl-based flow components.
To maintain these levels, every product batch is processed through our 26-step scientific testing routine:
This structured quality methodology guarantees that our components deliver long service lives, protecting municipal, industrial, and agricultural piping projects against unplanned shutdowns.
