Double Module Extrusion Machine for Lithium-Ion Batteries: High-Precision Automated Solution for Battery Manufacturing

Accelerating Global EV Transition: High-Precision Double Extrusion Technology

As global demand for lithium-ion batteries surges, rectangular prismatic cells

 have emerged as the gold standard for high-energy-density and safety applications. 

Sunkalead’s Fully Automatic Biaxial Module Extrusion Machine is engineered to meet 

the rigorous demands of modern battery manufacturing, combining PLC automation, 

force-feedback sensors, and AI-driven workflows to deliver unmatched precision and efficiency.

Key Technical Specifications

Process Technical Parameters

Extrusion Control:PLC-programmed precision (±0.5% accuracy),

 adjustable force (5–50 tons), stroke range (0–200 mm).

Strapping System:Servo-driven automatic strapping with ±2 N·m tension control, 

cycle time ≤15 seconds per module.

Human-Machine Interface:Pneumatic clamping for part positioning, 

emergency stop button, and intuitive touchscreen controls.

Data Traceability:USB-exportable reports log pressure/displacement/time parameters,

 compliant with ISO 9001 standards.

Six Core Advantages

1.Ultra-Precise Control

Ensures inter-electrode spacing tolerance ≤0.2mm, mitigating short-circuit risks in high-voltage modules.

2.Energy-Saving Efficiency

Reduces energy consumption by 60% vs. hydraulic systems, 

with maintenance costs slashed by 40%.

3.End-to-End Automation

Pre-programmed workflows support 12–16 modules/hour, 

with "one-click" model switching for 355–505Ah capacity variants.

4.Safety Redundancy

Dual-protection system (pressure relief valves + photoelectric sensors) lowers accident rates by 90%.

5.Scalable Architecture

Modular design integrates with MES systems and future AGV logistics for Industry 4.0 readiness.

6.Global Compliance

Certified to GB/T 36276-2018 safety standards, with thermal/vibration/impact resistance 

validated for automotive-grade applications.
