The Automatic Paperboard Bursting Strength Tester is engineered to measure the bursting strength of various materials, including paper, paperboard, and corrugated board, following the Mullen test method. This equipment is essential for quality assurance in industries where material durability is critical, such as packaging, printing, and manufacturing.
With a digital display and pressure converter, the tester automatically records the maximum rupture strength value when the sample breaks. The indication is digital, ensuring precise readings. The capacity ranges from 0 to 56 kgf/cm² with a resolution of 0.1 kgf/cm², providing high accuracy for detailed analysis.
Applications of this bursting strength tester are extensive, covering general paper, corrugated materials, toilet paper, wrapping paper, leather, cloth, and packaging films. It helps in effective product quality monitoring by simulating real-world stress conditions. The device includes an automatic clamping and loosening mechanism with an adjustable sample clamping force from 50 to 1200 kPa, enhancing usability and safety.
Key features include an acrylic protection device, test indicator light for visible rupture process observation, and a built-in LED light on the cover to monitor sample conditions during testing. The operation is fully automatic with oil pressure, automatic return, and data calculation, storage, and printing capabilities. It supports multiple units of measurement, such as kPa, lbs/in², and kgf/cm², with easy switching functionality.
Constructed with a stainless steel SUS#304 clamp ring of diameter Φ30.5±0.1 mm, the tester ensures durability and consistent performance. It uses 100% silicone hydraulic oil and operates at a pressure speed of 170±15 ml/min. The dimensions are 445×425×525 mm, powered by a single-phase AC220V source, and it weighs approximately 50 kg.
This product adheres to various international standards, including JIS, ASTM, TAPPI, ISO, and GB/T, making it suitable for global quality testing requirements. It is designed for use in laboratories, research institutions, and production facilities, providing reliable and fast testing cycles to support efficient quality feedback.
