Products and Technologies
Electro-permanent lifting magnets
Electro-permanent lifting magnets are designed to combine the controllability of electromagnets with the energy-retention characteristics of permanent magnets. A short electrical pulse changes the magnetic circuit, after which the magnet can remain engaged without continuous power. This architecture can reduce dependence on uninterrupted electrical supply during a lifting operation, although safe use still depends on correct load assessment, surface conditions, operating procedures, and equipment inspection.
HVR markets lifting systems for steel plates and other ferromagnetic products, including configurations intended for industrial material handling and heavy-load applications.
Battery lifting magnets
Battery-powered variants are intended for mobile or infrastructure-constrained applications. Their use can reduce the need for fixed electrical connections, while requiring appropriate battery management, charging procedures, and operational controls. HVR identifies battery lifting magnets as a distinct product category.
Magnetic chucks
Magnetic chucks provide workholding for machining operations. They are used to secure ferromagnetic workpieces during processes such as milling, grinding, and other metalworking operations. The technical value of such systems lies in distributing clamping force across the workpiece while leaving more of its surface accessible than many mechanical fixtures.
HVR lists electro-permanent magnetic chucks among its principal products and supplies versions for industrial machining applications.
Magnetic quick mold-clamping systems
Magnetic mold-clamping systems are particularly relevant to injection molding. They are designed to hold molds against machine platens and facilitate faster mold changes than conventional mechanical clamping arrangements in suitable applications. Potential operational benefits include reduced changeover labor, lower tooling-handling complexity, and improved compatibility with production scheduling based on shorter runs.
Their performance depends on mold geometry, magnetic contact area, platen and mold materials, load distribution, machine compatibility, and compliance with applicable safety requirements. HVR identifies magnetic quick mold clamping as one of its core product lines.
Magnetic grippers for automation
Magnetic grippers serve as end-of-arm tooling for robots and automated handling equipment. They can be configured to pick and place steel components, plates, and other ferromagnetic parts. In an automated cell, the gripper must be matched to payload, surface condition, acceleration, orientation, cycle time, and failure-response requirements.
HVR presents magnetic grippers as part of its automation portfolio and links them to applications in manufacturing and material handling.
Applications and End Markets
HVR’s systems serve industries in which ferromagnetic parts, tools, or workpieces must be lifted, positioned, clamped, or transferred.
| Sector | Typical relevance of HVR systems |
|---|---|
| Steel and metallurgy | Lifting and transferring plates, sections, and other steel products |
| Shipbuilding | Handling large steel panels and structural components |
| Automotive manufacturing | Workholding, component handling, tooling, and automated production |
| Injection molding | Magnetic quick mold changes and mold clamping |
| Mold and die production | Magnetic workholding during machining and finishing |
| Aerospace | Handling and machining of metallic components |

| New-energy manufacturing | Handling metallic components used in batteries, vehicles, and equipment |
| Electronics and automation | Robotic handling of suitable ferromagnetic parts |
The company’s plastics-industry relevance is concentrated in injection-molding operations. In that environment, magnetic clamping systems are auxiliary production technology rather than polymer-processing equipment. Their strategic importance is associated with mold-change time, line flexibility, operator exposure to heavy tooling, and integration with automated manufacturing systems.
Global Presence and Market Position
HVR sells to domestic and international customers and states that its products are exported to more than 30 countries and regions, including markets in Europe, North America, Japan, South Korea, Southeast Asia, and South America. Its international offering includes customized products and OEM or ODM-oriented engineering support.
The company’s competitive position is based primarily on specialization in electro-permanent magnetic systems rather than on the scale of a diversified machinery conglomerate. Relevant competitive factors include:
- Magnetic holding performance and safety margins
- Reliability of switching and control systems
- Compatibility with machine tools, molds, robots, and lifting equipment
- Custom engineering capability
- Compliance with customer and destination-market requirements
- Service support and delivery performance
- Ability to integrate hardware into broader automation systems
HVR reports that its electro-permanent lifting products have a significant share of the Chinese lifting-magnet market and that it has supplied more than 36,000 units to over 5,000 customers. These figures are company-reported and should be interpreted within the defined product category rather than as a measure of the entire global magnetic-equipment market.
Research and Development
Research and development at HVR centers on magnetic-circuit design, control systems, structural engineering, safety mechanisms, and application-specific integration. The company describes a patent portfolio covering invention patents, utility models, international patents, design patents, and software copyrights.
Key development areas include:
- Electro-permanent magnetic circuits for lifting and workholding
- Magnetic switching and control electronics
- Battery-operated lifting equipment
- Compact magnetic modules for robotic end effectors
- Mold-clamping systems compatible with injection-molding equipment
- Customized systems for unusual workpiece shapes or production conditions
- Integration of magnetic equipment into automated handling processes
The engineering challenge is not limited to generating magnetic force. Products must also maintain predictable performance across variations in workpiece thickness, air gaps, surface contamination, temperature, vibration, load orientation, and repeated operating cycles.
Sustainability and Environmental Initiatives
Electro-permanent technology can reduce electricity consumption during the holding phase because the magnetic state may be maintained without continuous energization. HVR markets this characteristic as an energy-saving advantage over continuously powered electromagnetic equipment.
Potential environmental and operational benefits include:
- Lower standby electricity demand
- Reduced heat generation in the holding device
- Less dependence on continuous power during handling
- Longer service intervals where the design eliminates certain moving or wearing parts
- More efficient mold-change and handling operations
These benefits depend on the application, operating cycle, equipment design, and maintenance regime. They do not remove the need to evaluate battery use, electronic components, manufacturing impacts, end-of-life treatment, and the safety consequences of power or control-system failures. For plastics processors, the environmental value of magnetic mold clamping is most directly connected to reduced changeover time and the electricity profile of the production system as a whole.
Quality Management and Certifications
Company and distributor materials associate HVR with ISO 9001 quality-management practices and CE- and TÜV-related conformity or certification claims. Such qualifications are relevant to international industrial-equipment sales, particularly where customers require documented design control, traceability, testing, and conformity assessment.
For lifting and clamping equipment, quality assurance generally involves verification of:
- Rated lifting capacity and safety factors
- Magnetic holding force under defined conditions
- Switching reliability
- Structural strength and fatigue resistance
- Control-system behavior during power interruption
- Electrical safety
- Product traceability and inspection records
The precise scope of any certification depends on the certificate, product family, issuing organization, and applicable market requirements.
Financial Performance and Economic Impact
Publicly accessible company materials describe HVR primarily through its products, export activity, customer base, and technical capabilities rather than through detailed audited financial statements. Its economic contribution is therefore best understood through its role as a specialized equipment manufacturer and exporter.
The company supports industrial activity through:
- Engineering and manufacturing employment in Zhuzhou
- Domestic and international procurement of components and services
- Supply of lifting and workholding equipment to manufacturing plants
- Support for mold-change and automation projects

HVR’s reported customer and delivery figures indicate a substantial installed base in its target product categories. Its commercial performance is linked to investment in steel processing, shipbuilding, automotive production, injection molding, factory automation, and new-energy manufacturing.
Innovations and Future Outlook
Several industry trends are likely to shape HVR’s development:
- Factory automation: Demand for robotic handling and machine-to-machine integration creates opportunities for magnetic grippers and intelligent end-of-arm tooling.
- Flexible manufacturing: Shorter production runs and greater product variety increase the value of rapid mold and fixture changes.
- Industrial safety: Manufacturers continue to seek handling systems that reduce manual lifting and improve control over heavy loads.
- Energy efficiency: Equipment that reduces continuous power consumption may become more attractive as electricity costs and carbon-management requirements receive greater attention.
- International conformity: Export growth requires continued attention to regional standards, documentation, cybersecurity where products are connected, and local service capability.
- Application-specific engineering: Customized magnetic systems are likely to remain important because load geometry, material properties, machine interfaces, and operating environments vary widely.
Future competitiveness will depend on combining magnetic performance with digital controls, condition monitoring, standardized machine interfaces, and demonstrable lifecycle benefits. In injection molding, the most consequential opportunities are likely to involve integration between magnetic clamping systems, mold-management procedures, robot cells, and production-control software.
