Fully Automatic Burst Strength Testing Machine
PRODUCT DETAILS
Carton Burst Strength Tester
Product Overview
The Carton Burst Strength Tester is a precision instrument designed to measure the maximum pressure resistance of corrugated cardboard, solid fiberboard, and other packaging materials under uniform radial pressure. This test determines the burst strength (also known as "Mullen strength"), a critical indicator of a material’s ability to withstand internal or external forces during transportation, stacking, or handling. The results help manufacturers optimize paper grammage, flute structures, and box design to meet industry performance standards.
Key Features
-
Accurate Burst Strength Measurement:
- Measures the maximum pressure a sample can withstand before rupturing, providing reliable data for quality control and material selection.
- Compliant with international standards such as ASTM D689, ISO 2758, and GB/T 454.
-
Dual Testing Modes:
- Supports standard burst testing (radial pressure) and optional ring crush testing (RCT) for versatile material evaluation.
-
High-Performance Components:
- Equipped with a precision hydraulic/pneumatic system for stable pressure application.
- High-accuracy load cells (±0.5% FS) and digital encoders ensure repeatable results.
-
User-Friendly Operation:
- Touchscreen HMI with preloaded test programs and customizable parameters (pressure speed, dwell time).
- Automatic calculation of burst strength (kPa or psi) and generation of test reports.
-
Safety & Durability:
- Overload protection and emergency stop function to prevent mechanical damage.
- Robust steel frame with anti-vibration design for continuous operation.
