Hebei Hongrui Environmental Protection Technology at CHINAPLAS 2026: Featuring Nylon Rods and Non-Destructive Metal-Rubber Separation Technology – Booth 4.2A45
2026-04-18
From April 21 to 24, 2026, the 38th CHINAPLAS will be held at the National Exhibition and Convention Center (NECC) in Hongqiao, Shanghai. Hebei Hongrui Environmental Protection Technology Co., Ltd. (Booth 4.2A45, Hall 4.2) will showcase its two core businesses: cast nylon rod series and non-destructive metal-rubber composite separation technology. We sincerely invite customers, industry experts, and partners to visit our booth for exchange and guidance.
Company Profile
Hebei Hongrui Environmental Protection Technology Co., Ltd. is a high-tech enterprise and a “Specialized and Sophisticated” (Specialized, Refined, Distinctive, Innovative) enterprise of Hebei Province. The company integrates R&D, design, manufacturing, and sales in the fields of waste metal-rubber product remanufacturing, high-value comprehensive utilization of organic solid waste, railway vehicle parts, and high-strength thermoplastic composites. With multiple production bases in China, its leading products have been fully promoted and applied in key technological transformation projects of China Railway Group.
Core Product I: Cast Nylon Rods
As an ideal engineering plastic for replacing steel, iron, and copper with plastic, Hongrui’s cast nylon rods (MC nylon rods) offer excellent comprehensive mechanical properties and processability:
High strength and wear resistance: High tensile and flexural strength, outstanding wear resistance, suitable for long-term friction conditions
Oil resistance and vibration damping: Excellent oil resistance, impact resistance, and vibration absorption, adaptable to complex dynamic loads
Dimensional stability: Low water absorption, good dimensional stability, not easily deformed over long-term use
Easy machinability: Supports secondary processing such as turning, milling, drilling, and grinding to meet various size and shape requirements
Product specifications: Available in customized diameters, lengths, and colors; support for machining into special-shaped parts such as nylon sleeves, nylon wheels, guide rails, sliders, and gaskets according to drawings.
Typical application areas:
Mechanical manufacturing: gears, turbines, bearings, impellers, guide wheels, conveyor wheels
Automotive industry: transmission components, suspension bushings, seal support rings
Chemical equipment: corrosion-resistant pump and valve parts, pipe supports, seals
Aerospace and low-altitude economy: lightweight structural parts, UAV components
Railway vehicles: wear-resistant plates, insulation parts, buffer components
Hongrui’s cast nylon rods have been supplied to multiple equipment manufacturers in batches, with stable quality and high cost-performance. Customers are welcome to request samples and technical data at the booth.
Core Business II: Non-Destructive Metal-Rubber Composite Separation Technology
Hongrui holds a patent for the “Non-destructive separation method for metal-rubber composite products” (patent number available on-site). This technology enables efficient and clean separation of metal and rubber without damaging the metal skeleton structure, achieving dual resource utilization of both materials.
Technical advantages:
Non-destructive separation: No damage to the metal skeleton; the separated metal can be directly reused in the remanufacturing of railway vehicle components such as side bearings and axle boxes, maintaining original mechanical properties
High-value rubber utilization: Recovered rubber is further processed into reclaimed rubber for industrial product manufacturing
Environmental protection and energy saving: Compared to traditional incineration or landfilling, significantly reduces harmful gas emissions
Significant cost reduction: Saves raw material procurement costs for customers
Application scale:
The technology has been industrialized across multiple production bases, processing 12,000 tons of waste metal-rubber composite parts annually, widely used in the remanufacturing of railway freight car damping parts and engineering machinery rubber-metal composite products.
Alignment with the exhibition theme:
CHINAPLAS 2026 is themed “Transform, Collaborate, Shape a Sustainable Future.” Hongrui’s non-destructive separation technology is a typical representative of “Circular Economy” and “High-End Technology, Made in China.” Through this independent innovation, the company helps the railway and machinery industries significantly reduce solid waste emissions and raw material consumption, promoting green transformation of the industrial chain.
Other Business (Supplementary)
In addition, the company is also engaged in the R&D and manufacturing of high-strength thermoplastic composites (such as railway flatcar composite flooring and tank car skids) and cast nylon special-shaped parts, providing customized composite structural component solutions according to customer needs.
Sincere Invitation
From April 21 to 24, 2026, at Booth 4.2A45, Hall 4.2, National Exhibition and Convention Center (NECC), Hongqiao, Shanghai, the Hongrui team will present nylon rod samples, non-destructively separated metal skeletons and reclaimed rubber products, along with technical data and one-on-one discussions. Technical staff will provide detailed explanations of the non-destructive separation process, nylon rod selection advice, and customization solutions.
Professionals from railway transportation, automotive manufacturing, mechanical equipment, aerospace, low-altitude economy, chemical equipment, solid waste resource utilization, and related fields are welcome to visit and explore innovative paths in nylon material applications and circular remanufacturing of metal-rubber composite parts.
