Products and Technologies
Injection-Molding Robots
Lijiang manufactures robot arms designed for use with injection-molding machines. Product configurations identified in company and industry listings include:
- Sprue-picker and swing-arm robots
- One-axis and two-axis robots
- Three-axis traverse robots
- Five-axis robots
- Large-beam and gantry systems
- Customized take-out and handling systems
The principal technical function of these systems is to enter the mold area, remove the molded article or runner, and transfer it to a defined position such as a conveyor, bin, inspection station, assembly fixture, or packaging area. Servo-driven axes can provide controlled movement, repeatable positioning, and programmable acceleration and deceleration. These capabilities are relevant where short cycle times, consistent part handling, and reduced operator access to the mold area are required.
Robot selection depends on several factors:
- Injection-molding machine size and mold layout
- Part mass and geometry
- Required stroke and reach
- Mold-opening distance
- Cycle time
- Number of downstream operations
- Required orientation or placement accuracy
- Integration with the machine controller and safety circuits
Auxiliary Equipment and Material Handling
The company’s auxiliary portfolio includes systems associated with centralized material handling and injection-molding support. Centralized feeding systems can connect drying, storage, conveying, filtration, and machine-side loading equipment. In a properly configured installation, these systems reduce manual pellet handling and help maintain a more controlled supply of polymer material to individual machines.
Material-handling systems are particularly significant for engineering plastics and moisture-sensitive polymers, for which drying and controlled conveying can influence processing stability and finished-part quality. The performance of a complete system depends not only on individual components but also on conveying distances, material throughput, hopper sizing, filtration, sensor reliability, and control logic.
Integrated Workshop Systems
Lijiang describes its intelligent-workshop offering as including the planning of water, electricity, and gas systems, together with environmental-protection and production-support infrastructure. Such systems may involve:
- Utility distribution for injection-molding machines and auxiliaries
- Cooling-water circulation and process-water planning
- Compressed-air distribution
- Electrical-control and equipment-layout coordination
- Centralized feeding and material-routing design
- Workshop environmental and support systems
- Equipment installation and commissioning
The integration of these systems can reduce conflicts between machinery placement, utility routing, material movement, maintenance access, and future production expansion. It also enables the automation supplier to address production-line requirements at the factory-planning stage rather than after individual machines have been installed.
Other Industrial Applications
Industry listings associate Lijiang equipment with stamping, die casting, lathe loading, and related machine-tending operations. These applications use a similar automation principle: a robot performs repetitive loading, unloading, transfer, or handling tasks while the primary machine carries out forming, machining, or casting.
The technical requirements vary by application. Die-casting and stamping environments may require greater attention to heat, impact, guarding, part orientation, and cycle synchronization, while machine-tool loading may require workpiece detection, chuck or fixture coordination, and chip or coolant management.
Applications and End Markets
Lijiang’s principal end market is plastics injection molding. The company’s equipment can support production of components and products used in sectors such as:
- Consumer goods
- Electrical and electronic products
- Automotive components
- Household appliances

In plastics processing, robot development is closely connected with mold technology and injection-machine control. A robot must operate within the available mold-opening window, avoid interference with inserts and cavities, and coordinate its motion with machine safety signals. For more complex cells, the robot may also need to synchronize with conveyors, vision systems, labeling equipment, trimming devices, leak testers, or packaging units.
Sustainability and Environmental Initiatives
Automation can contribute to more efficient plastics production by stabilizing cycle times, reducing handling losses, limiting manual intervention, and enabling consistent process control. Centralized feeding and workshop planning may also reduce unnecessary movement of materials and improve the organization of utilities and equipment.
Lijiang’s environmental relevance is primarily indirect and operational rather than based on the production of recyclable polymers or waste-treatment technologies. Potential benefits of its systems include:
- More consistent machine utilization
- Reduced manual material handling
- Improved production-line organization
- Lower scrap risk where stable handling prevents damage
- Better coordination of cooling, compressed air, and electrical systems
- Support for closed-loop or controlled factory layouts
The environmental performance of an automated plastics plant ultimately depends on the injection-molding machines, resin selection, process settings, cooling systems, electricity source, product design, and recycling practices. Automation alone does not determine the life-cycle impact of molded products.
Financial Performance and Economic Impact
Lijiang is a privately controlled Chinese limited-liability company. Corporate-information listings report a registered capital of 5 million yuan and identify the company as established in July 2007. Publicly available company information does not provide the audited revenue, earnings, export proportion, or segment-level financial data normally associated with a listed corporation.
