Product Overview

The HM-MF03C Leakage and Seal Strength Tester is a comprehensive dual-purpose positive-pressure testing system engineered for the integrated evaluation of bottle closures and container bodies. Configured with a large-capacity transparent sealed test chamber (inner diameter Φ230×280 mm), the HM-MF03C accommodates both standalone bottle caps and assembled blow-molded bottles (PET, HDPE, glass, etc.). It quantitatively determines cap seal integrity, thread strip resistance, full bottle compressive resistance, and catastrophic container burst pressure. By applying controlled internal pneumatic pressure, the system simulates internal carbonation expansion, mechanical stacking loads, and transport shocks, providing bottling plants, packaging converters, and quality inspection laboratories with complete container verification.

Key Features

Dual-Purpose Testing Capability: Seamlessly transitions between standalone bottle cap sealing evaluation and complete container bottle body burst pressure testing using interchangeable tooling inside the Φ230×280 mm chamber.
Large-Capacity Transparent Test Chamber: Heavy-wall acrylic cylinder provides generous internal volume (Φ230×280 mm) and 360-degree visibility for submerged bubble leak identification and container deformation monitoring.
High-Precision SMC Pneumatics: Incorporates imported SMC pneumatic regulation components for smooth pressure delivery up to 1 MPa with ±1% FS system accuracy.
7-Inch Color Touchscreen Interface: Interactive industrial UI facilitates rapid test mode selection, pressure setpoint entry, and real-time operational status review.
Dynamic Pressure Curve Tracking: On-screen graphical display renders real-time pressure-time profiles, automatically logging initial seal yield points, creep pressure drops, and catastrophic burst pressures.
Versatile Test Modes: Provides automated execution for burst (cracking) test, timed creep test, and creep-to-failure testing modes.
Data Traceability to GMP Standards: Multi-tiered user authentication with password login meets China GMP criteria for pharmaceutical and food contact packaging quality data integrity.
Integrated Data Documentation: Features an onboard thermal micro-printer for immediate test ticket printing and a USB port for digital record export.

Applications

Plastic Bottle Caps and Closures: Seal tightness, thread stripping resistance, and burst pressure testing for anti-theft caps, beverage closures, and condiment lids.
Complete PET and Plastic Bottles: Internal pressurization burst testing, base expansion analysis, and sidewall compressive resistance for beverage, mineral water, and pharmaceutical bottles.
Container Closure Systems (Assembled Packaging): Total seal performance evaluation of the cap-bottle interface under internal positive pressure to simulate carbonated beverage containment.
Blown Plastic Containers & Jars: Resistance to cracking, bottom roll-out, and volumetric expansion under sustained internal pressure.
Paper Cans and Easy-Open Metal Ends: Seaming integrity and burst resistance for composite food canisters and beverage cans.
