Leakage and Seal Strength Tester

Product Overview

The HM-MF03B Leakage and Seal Strength Tester is a specialized positive-pressure testing system engineered for the rigorous seal performance evaluation of bottle closures. Featuring a transparent cylindrical test chamber (inner diameter Φ230×280 mm) and dedicated closure fixtures, the HM-MF03B quantitatively measures seal leakage limits, cap-to-neck thread trip strength, and burst pressure in plastic anti-theft caps, beverage closures, and container lids. By injecting controlled positive air pressure into the closure interface, the instrument accurately simulates pressure buildup during hot filling, carbonation retention, warehousing, and transportation, delivering indispensable quality data for beverage bottlers, edible oil packaging, and cap manufacturers.

Key Features

• Transparent Cylindrical Test Chamber: Includes a Φ230×280 mm high-clarity acrylic sealed barrel, providing 360-degree observation of bubble release, seal deformation, and cap detachment during pressurized submersion testing.
• Specialized Anti-Theft Cap Fixture: Engineered to securely clamp beverage bottle caps, edible oil closures, and condiment lids, applying internal pressure directly to evaluate thread engagement and liner sealing integrity.
• 7-Inch Color Touchscreen: Intuitive interface with single-button test initiation, programmable pressure holding phases, and support for remote firmware maintenance.
• High-Precision SMC Pneumatics: Powered by premium SMC brand imported pneumatic components for smooth pressure regulation up to 1 MPa with ±1% FS accuracy.
• Real-Time Dynamic Pressure Curve: Real-time on-screen graphic tracking of internal pressure changes, clearly showing sealing retention, leakage drop, and cap trip rupture points.
• Three Testing Modes: Supports burst test, creep test, and creep-to-failure testing to assess instantaneous cap blow-off thresholds and prolonged pressure containment.
• China GMP Compliance: Features multi-level user authority management with password authentication for verifiable packaging quality inspection records.
• Built-In Reporting: Integrated thermal micro-printer and USB interface for direct printing and convenient digital test data archiving.

Applications

• Plastic Anti-Theft Bottle Caps: Seal integrity, thread stripping torque resistance, and burst pressure testing for pure water, carbonated soft drink, and juice bottle closures.
• Edible Oil Barrel Closures: Sealing tightness, pouring spout leak resistance, and pressure endurance for vegetable oil container caps.
• Condiment & Food Packaging Caps: Leakage and pressure retention evaluation for soy sauce, vinegar, cooking wine, and sauce bottle closures.
• Metal Easy-Open Ends: Buckle and burst pressure verification for 3-piece beverage cans and composite paper snack canister closures.
• Pharmaceutical Bottle Closures: Child-resistant and tamper-evident cap sealing verification complying with YBB pharmaceutical packaging standards.
