Direct from our precision manufacturing lines. Engineered to international standards (DIN8077/8078) and fully certified for demanding industrial applications.
In the globalized plastic manufacturing landscape, capital expenditure (CapEx) optimization and rapid time-to-market are critical drivers of competitive advantage. Sourcing pre-owned and refurbished injection molds offers a strategic path for enterprises to bypass the lengthy lead times associated with custom mold tool design (often 8 to 16 weeks) while securing industrial-grade steel molds at a fraction of the cost of new tooling. However, procurement of used injection molds requires rigorous engineering due diligence, strict compliance validation, and a transparent refurbishment process.
Ehao Plastic Group stands at the forefront of this industrial sector as a high-tech private enterprise integrating advanced R&D, precision tool fabrication, and high-performance injection molding. Backed by joint engineering partnerships with the Chinese Academy of Sciences and Zhejiang University, Ehao combines academic material science with shop-floor manufacturing excellence. By housing state-of-the-art automated tooling centers, computer-integrated injection machinery imported from Germany, and maintaining an exhaustive 26-step scientific testing protocol, we guarantee that every pre-owned mold or custom piping product meets world-class quality benchmarks, including international DIN8077 and DIN8078 standards.
Our ongoing partnerships with the Chinese Academy of Sciences and Zhejiang University feed directly into our engineering protocols, optimizing polymer flow analysis, thermal distribution, and metallurgy mapping for used mold reclamation.
Utilizing high-end computer-controlled injection machinery from Germany, we execute precision tooling modifications, cavity remediation, and complex core machining to tolerances within ±0.01mm.
Every used mold is subjected to an exhaustive 26-step verification process, covering metallurgy inspection, non-destructive crack detection, waterway pressure testing, and final cycle simulation to verify a 100% defect-free output.
Our tooling solutions and plastic products cater to critical global industries, delivering long-term reliability and precise dimensional stability.
Modern plastic manufacturing operations face the dual challenge of resource conservation and pricing volatility. China's injection molding ecosystem has undergone a transition from high-volume assembly to high-technology automation (Industry 4.0). Under this industrial paradigm, Ehao Plastic Group utilizes integrated supply chains to provide rapid turnaround times for used mold modifications, core replacements, and custom configuration upgrades.
By leveraging regional tooling clusters in China alongside German automated machining hardware, we offer an unmatched turnaround framework. When a global enterprise purchases pre-owned injection tooling, our engineering facility can immediately execute modifications—such as adding hot-runner systems, upgrading cavity materials, or modifying gate placements—faster than a domestic tool room in North America or Western Europe can design a new mold. This hybrid manufacturing workflow maintains the resilience of global supply chains by keeping lead times low and component availability high.
The technical integrity of a used injection mold depends heavily on its historic shot count, cavity steel metallurgy, and maintenance history. Ehao's technical team utilizes advanced analysis methods to extend the operational life of every mold tool we deliver:
| Steel Class | Typical Hardness (HRC) | refurbished Lifespan (Cycles) | Best Suited Application Polymers |
|---|---|---|---|
| AISI P20 / 1.2311 | 28 - 32 HRC | 300,000 - 500,000 | PP, PE, ABS, Non-abrasive resins |
| AISI H13 / 1.2344 | 48 - 52 HRC | 800,000 - 1,000,000+ | PVC, Polycarbonate, Glass-filled Nylon |
| S136 / 1.2083 (Stainless) | 48 - 54 HRC | 1,000,000+ | Corrosive plastics, High-gloss transparent parts |
Sourcing pre-owned tooling directly supports global carbon footprint reduction and industrial circular economy initiatives. Manufacturing a medium-sized multi-cavity injection mold consumes megawatt-hours of energy and metric tons of high-grade tool steel. Reclaiming and refurbishing existing mold bases and core elements reduces the energy footprint by up to 80% compared to new mold fabrication. Ehao is proud to partner with eco-conscious brands worldwide to deliver tooling configurations that meet both sustainability goals and strict financial metrics.
Acquiring industrial machinery requires a relationship that extends beyond transaction endpoints. Ehao Plastic Group assists global partners from the early phases of selection and mechanical configuration down to financial planning and technical execution, maximizing operational ROI.
Our capabilities encompass not only pre-owned mold tooling but also custom product fabrication (including extrusion and injection molded parts). Our team can design, manufacture, and qualify new molds or adapt existing tooling based on physical parts, technical schematics, or CAD files supplied by our clients. This agility has earned our products high praise in European, American, and Southeast Asian markets.

We execute a comprehensive non-destructive testing (NDT) protocol. This includes ultrasonic cavity testing to locate sub-surface steel fractures and crack-detection dye tests. The molds are subsequently set up on our German computer-controlled injection molding machines for real-condition pilot runs to confirm part dimensional consistency under production pressures.
Yes, we specialize in adapting pre-existing molds. Our engineering shop can change core inserts, engrave custom client branding, adapt slider locations, or convert older cold-runner tooling into modernized pneumatic hot-runner configurations to minimize material waste and cycle times.
Absolutely. Our PVC/UPVC ball valves and connected pipe fittings are designed, manufactured, and evaluated under German engineering standards, matching DIN 8077 and DIN 8078 specifications. This ensures 100% mechanical compatibility with standard metric European pressure piping networks.
The remaining lifecycle is determined by the grade of mold steel (e.g., P20, H13, or S136) and its past usage history. We supply pre-owned tooling that has completed only a minor fraction of its design life. An H13 steel mold regularly delivers over 500,000 to 1,000,000 subsequent shots after refurbishment and cavity re-polishing.
We have exported machinery, tooling, and pipeline components to 28+ countries across North America, Europe, and Asia. We provide comprehensive export documentation, custom packaging designed to resist sea-salt corrosion (vacuum sealing, rust-prevention coatings), and HS-code alignment to simplify import clearance at destination ports.
