Introduction
ZHENGZHOU LIANHE ELECTRIC CO., LTD. (郑州联合电气有限公司) is a Chinese industrial equipment company focused on melt filtration and continuous screen changers for plastics and other viscous-material processing applications. The company states that it develops, promotes, and services non-stop screen changer systems for use in plastics, rubber, chemical fiber, adhesives, sols, and coating materials, positioning itself as a specialized supplier to polymer-processing and related process industries.
Its core business is centered on equipment that enables screen changing without stopping production, a function that is important in extrusion and other melt-processing lines where maintaining flow continuity can improve output stability and reduce material loss. The company says its product range includes plate-type, column-type, and screen-belt changers, and that it also offers customized solutions for different media and industrial conditions.
History and Development
Zhengzhou Lianhe Electric describes itself as having a technical team with many years of experience in the design and production of continuous screen changers. Publicly available materials indicate that the company has built its identity around the practical application of melt-filtration technology rather than broad diversification into unrelated machinery.
Key development themes highlighted in company materials include:
- Focus on non-stop screen changer technology: The company emphasizes research, promotion, and technical services for continuous screen changers as its principal line of activity.
- Product portfolio expansion: It identifies multiple product families, including plate, column, and screen-belt designs, suggesting incremental development across different filtration configurations.
- Application-oriented customization: The company states that it can tailor screen changers for different industries and media, indicating a move beyond standard catalog products toward process-specific engineering.
The company is also listed by Chinaplas’s online eMarketplace as a plastics and rubber supplier, where it is described as a specialized and innovative enterprise recognized by Chinese government policy frameworks.
Business Operations and Segments
The company appears to operate primarily as a specialized equipment manufacturer and technical service provider rather than a large diversified industrial group. Its activities, as described in public company materials, include:
- Research and development of melt filtration and screen-changing systems
- Production and application support for continuous screen changers
- Technical services related to installation, use, and process adaptation
- Customized engineering for different materials and processing conditions
Its business focus is closely tied to industrial melt filtration, which is used to remove contaminants and maintain product quality in viscous-material processing lines.
Products and Technologies
The company’s product offerings are built around non-stop screen changers, a class of filtration equipment used in continuous processing systems. In practical terms, such equipment helps processors replace filter screens without shutting down the line, which can support steadier throughput and reduce waste.
Main product types
| Product type | Functional role |
|---|---|
| Plate-type screen changer | A filtration unit designed for melt processing lines requiring screen replacement during operation. |
| Column-type screen changer | A continuous filtration configuration used for viscous materials and stable line operation. |
| Screen-belt screen changer | A belt-based design intended to support continuous screen replacement and filtration efficiency. |
The company states that its products are designed to be easy to operate, simple to maintain, and suitable for non-stop, no-leakage, low-loss, high-efficiency processing. It also says that its systems are used to filter a range of melt or viscous materials, including plastics, rubber, chemical fiber, adhesives, sols, and coatings.
From an industry perspective, this places the company in the specialized segment of melt filtration equipment, which is relevant to extrusion, compounding, polymer recycling, and other process lines where contamination control and stable melt flow are operational priorities. That broader technical role is consistent with the company’s emphasis on reliability, product consistency, and custom engineering.
Applications and End Markets
The company identifies a range of industrial end uses for its equipment, including:
- Plastics processing
- Rubber processing
- Chemical fiber manufacturing
- Adhesives and sealant-related materials
- Sols and coating materials
These end markets share a need for clean melt or viscous-fluid filtration, where screen changers help maintain quality and process continuity. In plastics manufacturing, such systems are typically relevant to extrusion-based processes and other operations where contamination or pressure buildup can affect product quality and line efficiency; that broader application is consistent with the company’s stated product purpose, although the specific machine models and line configurations are not detailed in the available sources.
Global Presence and Market Position
Available sources do not indicate a large multinational footprint. The company’s public-facing materials and exhibition listings point to a domestic Chinese industrial supplier with presence in plastics-industry trade channels. Its inclusion on Chinaplas’s supplier platform suggests participation in a major plastics-industry exhibition ecosystem, which is a common channel for specialty machinery makers seeking buyers, distributors, and process-industry customers.
The company’s market position appears to be defined more by specialization than scale. Rather than competing across broad machinery categories, it concentrates on a narrower segment of melt filtration and screen-changing solutions.
Sustainability and Environmental Initiatives
The company describes its products as energy-saving and environmentally friendly, and emphasizes reduced material loss through non-stop screen changing. Those claims are consistent with the operational logic of continuous filtration systems, which can help reduce downtime and waste during processing.
Its materials also stress low leakage, low loss, and improved production efficiency, which are relevant to resource conservation in industrial processing. The sources available here do not provide quantified sustainability metrics, life-cycle data, or formal environmental reporting, so any assessment of environmental performance should be treated as qualitative rather than measured.
Leadership and Corporate Governance
The available sources do not provide detailed public information on senior leadership, board structure, or ownership. The company instead presents itself through its technical capabilities, service philosophy, and product applications.
Its stated operating principles include:
- “Technology first” and quality-oriented manufacturing
- Customer-first service
- Cooperation and mutual benefit as a business philosophy
These statements reflect a typical governance and commercial posture for a specialized industrial supplier, but they do not substitute for formal corporate governance disclosures.
Innovations and Future Outlook
The company’s innovation profile is centered on continuous screen-changing technology and the practical adaptation of that technology to different materials and process conditions. Its emphasis on customized solutions suggests that future development is likely to remain focused on application engineering rather than mass-market standardization.
Relevant industry trends for this type of equipment include:
- Growing demand for process efficiency and reduced downtime in plastics manufacturing
- Increased attention to material recovery and waste reduction
- Continued need for contamination control in recycled and compounded polymers
- Demand for equipment that can be integrated into diverse viscous-material production lines
Within that context, Zhengzhou Lianhe Electric’s prospects are likely tied to its ability to maintain product reliability, adapt to changing process requirements, and support customers across adjacent viscous-material industries.
Summary
ZHENGZHOU LIANHE ELECTRIC CO., LTD. is a specialized Chinese manufacturer of non-stop screen changers for melt filtration in plastics and related process industries. Its business is defined by continuous-filtration equipment, customization for different materials, and a service model focused on stable operation, reduced waste, and process efficiency.
