ATOMFAIR HSM729 HEAT SEALING MACHINE

RESEARCH GRADE EQUIPMENT

Product Overview

The ATOMFAIR HSM729 Heat Sealing Machine is a precision thermal bonding system with 300°C temperature control 0.5-0.7MPa pressure capability, purpose-built for flexible-packaged lithium-ion battery sealing in research and pilot production environments. The machine operates by generating heat through heating tubes and transferring it to a copper sealing head; under controlled pressure, the aluminum-plastic film is heated and softened to a near-molten state, completing pressing and fusion bonding to achieve reliable encapsulation. The thermocouple and temperature controller maintain precise constant temperature (±adjustable) for sealing consistency, while the built-in pressure gauge provides real-time monitoring. Featuring top side sealing without mold replacement, the HSM729 supports both top and side sealing configurations up to 200 mm without requiring mold changes, improving operational efficiency and reducing consumable costs. The upper mold reaches a maximum of 300°C (recommended 200°C) and the lower mold 300°C (recommended 100°C), with sealing time adjustable from 0–99 seconds (standard 2–3 s). With energy-saving efficiency over 50% compared to similar products, a compact footprint (320 × 320 × 500 mm, 30 kg), and unique anti-scald safety design, the V2.0 HSM729 delivers firm, flat, and neat sealing marks at 1000 W on AC 220 V/50 Hz power.

Key Features & Advantages

Precise Temperature Control via Thermocouple and PID Controller: The sealing head temperature is precisely adjustable and maintained at a constant level through thermocouple feedback and temperature controller regulation, ensuring consistent sealing quality across all production batches.
Built-in Pressure Gauge for Real-Time Monitoring: The integrated pressure gauge enables accurate control and real-time monitoring of sealing pressure (0.5–0.7 MPa, adjustable), ensuring stable and repeatable sealing quality for aluminum-plastic film bonding.
Dual-Mode Top and Side Sealing Without Mold Replacement: Supports both top sealing and side sealing configurations up to 200 mm without requiring mold changes, improving operational efficiency and eliminating mold replacement costs between different sealing operations.
Over 50% Energy-Saving Efficiency with Anti-Scald Safety Design: Unique safety protection and anti-scald design improve operational safety while the energy-saving efficiency exceeds 50% compared to similar products, effectively reducing long-term operating costs.

APPLICATION SCOPE: Top and side sealing of flexible-packaged (pouch) lithium-ion batteries in research laboratories and pilot production lines. Aluminum-plastic film heat sealing for battery encapsulation. Suitable for battery prototypes and small-batch production requiring reliable, consistent sealing with flat and neat appearance.

PACKAGING & DELIVERY: Each HSM729 heat sealing machine is securely packed for equipment transport. Standard configuration includes the sealing unit with upper and lower copper molds, temperature controller, pressure gauge, and control system. Installation guidance and operational training support are provided upon request.

IMPORTANT NOTICE: Recommended operating temperatures are 200°C (upper mold) and 100°C (lower mold) for typical aluminum-plastic film sealing; maximum 300°C capability should be used with caution. Sealing time is adjustable from 0–99 seconds with standard setting of 2–3 seconds. The sealing edge width is standard 5 mm and customizable as required. The anti-scald design provides safety protection but operators should still exercise caution around heated sealing heads. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.
