Structural components for ESS / UPS
Samjin LND makes the structural components that align, insulate, secure, and protect cells within ESS and UPS battery modules.
WHY IT MATTERS
Reliable power when it matters most.
TWO SYSTEMS, TWO ROLES
UPS reduces the risk of power interruptions, while ESS stores electricity for use when needed. Their roles differ, but both support reliable, efficient use of power.
Stores electricity for periods of high demand, improving energy use and system flexibility.
- Solar and wind integration
- Industrial and commercial peak demand management
- Microgrids
- Charging infrastructure
THE FUTURE OF POWER
Energy storage and power continuity are essential infrastructure.
How we generate electricity and where we use it are changing rapidly. Integrating more renewable energy and keeping digital infrastructure running reliably make the storage, flexibility, and power continuity provided by ESS and UPS increasingly important.
Growing demand for reliable power
Power demand is increasingly concentrated in facilities such as AI data centers. At the same time, more automated operations depend on uninterrupted power, where even a brief outage can cause significant losses.
Renewables account for a growing share of power.
Storage and grid flexibility are needed to manage fluctuations in solar and wind generation and make power available when it is needed.
Power systems are becoming more distributed.
Factories, buildings, charging stations, and microgrids are increasingly generating, storing, and using their own power.
SAMJIN LND · OUR CONTRIBUTION
Precision components for sustainable power infrastructure.
Samjin LND makes cell holders, busbar holder assemblies, cases, covers, and frames used inside battery modules, rather than complete ESS or UPS systems. We injection-mold and automatically assemble these components to align, insulate, secure, and protect cells, then check quality using AI-powered vision inspection.

SYSTEM POSITION
Where our components fit
From cell holders to cases, we manufacture the structural components that support and protect cells within battery modules.
SYSTEM CONTEXT
Power sources
Where electricity typically enters the system.
UPS or ESS system
Maintains power continuity or stores energy for later use.
BATTERY MODULE / PACK AREA
Internal and external plastic structures around battery cells
Outer structureHousings, cases, and covers
Internal structural componentsCell holderBusbar holder assemblyStructural frame
Plastic parts that contact battery cells directly or keep them aligned, insulated, and secure within the module.
BATTERY CELLSBattery cellsOutside our production scope
Scope: This is a general diagram to explain the system. Samjin LND produces internal and external plastic structural components, including cell holders, busbar holder assemblies, cases, covers, and frames. We do not manufacture battery cells. Actual supply scope and specifications vary by project.
COMPONENT FAMILIES
Each component has a job to do
From components that align and insulate cells to cases and frames that protect modules.
01CELL MODULE
Cell module structure
Cell holder
Structural components that align and insulate battery cells while maintaining consistent spacing.
02POWER DISTRIBUTION
Power connections and support
Busbar holder assembly
Holds busbars securely in place and provides insulation. Manufactured through automated assembly and AI-powered vision inspection.
