Explore our leading range of high-performance PVC, UPVC, PP, and PPR components manufactured with advanced injection molding technologies.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, pipe fittings, and high-precision injection moulds. As a domestic market leader of PVC/UPVC ball valves in China, Ehao has pioneered engineering pathways to bring industrial-grade structural integrity to consumer applications, including the custom manufacturing of premium-quality plastic toys.
Since our inception, our technological roadmap has been supported by the prestigious Chinese Academy of Sciences and Zhejiang University. By introducing advanced production lines and computer automatic injection molding machines directly from Germany, we have set a global standard in polymer fabrication. Every single component runs through 26 steps of rigorous scientific testing under strict quality control to guarantee a 100% ex-factory pass rate. Our products fully comply with international DIN8077 and DIN8078 standards, establishing world-class performance and structural safety benchmarks.
“The core spirit of Ehao Plastic Group lies in honesty, dedication, innovation, and return. We operate on a foundation of 'Quality for Survival, Science & Technology for Development, Management for Benefits, and Service for Credit.'”
Our operational capabilities extend beyond standard stock. We specialize in custom plastic moulds, manufacturing products directly from supplied materials, technical drawings, or physical samples:
We actively export to 28 countries and regions, including Europe, North America, and Southeast Asia, earning prestigious acclaim from global procurement directors.
Deep-dive analysis of manufacturing processes, polymer material safety, and mechanical engineering for high-volume B2B toy brands.
The foundation of premium toy manufacturing lies in tool and die design. We deploy advanced CAD/CAM software to optimize wall thickness, gating, and venting systems. Leveraging the engineering support of Zhejiang University, our tools feature high-wear tool steels (such as H13 or S136) to endure millions of high-pressure cycles. This minimizes parting lines, prevents flash, and ensures safety for children's toys.
Toy safety begins at the molecular level. Unlike standard consumer goods, injection-molded toys require strict heavy-metal-free, BPA-free, and phthalate-free polymers. We process high-impact ABS, food-safe polypropylene (PP), elastomeric TPEs, and shatterproof polycarbonate (PC). Every batch of raw materials is fully traceable and meets REACH, RoHS, and EN71 toxicity standards.
Consistency across multi-cavity molds requires high-precision machinery. Our automated production floors feature German injection molding units that regulate temperatures to within ±0.5°C and hold clamping pressures up to 1200 tons. This technology guarantees dimensional stability, eliminates sink marks, and maintains strict tolerances (+/-0.05mm) for interlocking toy blocks and modular assemblies.
The international toy market demands speed-to-market, cost-efficiency, and strict compliance. High-volume buyers face risks including fluctuating polymer pricing, supply disruptions, and regulatory compliance. Ehao Plastic Group addresses these challenges with integrated manufacturing capabilities. By operating domestic raw material channels, leveraging automated production, and holding direct access to major maritime hubs, we deliver resilient logistics and stable pricing to toy brands in North America, Europe, and Latin America.
Additionally, our tooling services allow brands to consolidate their supply chains. We manage everything from initial concept design and SLA prototyping to mold testing, mass production, and final assembly under one roof. This minimizes the risk of intellectual property theft and shortens the lead time from tool development to retail-ready production runs.
Our high-tech injection capabilities serve multiple sectors, from domestic piping to specialized recreational products.

Key information regarding production limits, material validation, compliance pathways, and custom tooling projects.
We implement a 26-step quality control protocol that monitors manufacturing from raw polymer arrival to final packing. Every batch of plastic resin undergoes testing for heavy metals and chemical composition. Our physical testing laboratories perform drop, load, and tensile strength evaluations to ensure no small components break off during use, maintaining compliance with EN71 and ASTM F963.
Yes. Ehao regularly works with client-supplied tooling, 3D CAD files, and reference samples. We protect our clients' intellectual property through structured Non-Disclosure Agreements (NDAs). All customer molds are cataloged, stored in secure facilities, and used exclusively for your authorized production runs.
For custom projects, the mold design and manufacturing process generally takes between 30 to 45 days, depending on part complexity. Once the client approves the initial samples (T1 trials), mass injection molding production runs are typically completed within 15 to 30 days, supported by our high-speed German automated machines.
These relationships allow us to troubleshoot challenging molding requirements, design complex multi-cavity tools, and formulate custom polymer blends. This academic support helps us address issues like shrinkage rates, flow lines, and durability, providing advanced technical solutions for our clients.
