Carton Edge Crush & Ring Crush Testing Machine

Product Overview

The Carton Edge Crush & Ring Crush Testing Machine is a precision instrument designed to evaluate the compressive strength of corrugated cardboard boxes, critical for assessing their durability during transportation, stacking, and handling. This equipment specializes in two key tests:

Edge Crush Test (ECT): Measures the resistance of corrugated board to vertical compression along its edges.
Ring Crush Test (RCT): Evaluates the compressive strength of corrugated medium or combined board in a ring-shaped specimen.

These measurements help manufacturers optimize flute profiles, paper grammage, and box design to meet industry demands for cost-effective, high-performance packaging.

Key Features

Dual-Function Testing:
- Simultaneously performs Edge Crush Test (ECT) and Ring Crush Test (RCT) with interchangeable fixtures.
- Supports testing of corrugated board, solid fiberboard, and recycled materials.
High Accuracy & Stability:
- Equipped with precision load cells (accuracy ±0.5%) and digital encoders for force/displacement measurement.
- Robust hydraulic/pneumatic system ensures consistent pressure application.
User-Friendly Operation:
- Touchscreen HMI with preloaded test standards (e.g., ASTM D642, ISO 3037, TAPPI T811) and customizable parameters.
- Real-time data display, automatic calculation of peak load, and failure analysis.
Versatile Sample Handling:
- Adjustable clamps for specimens of varying sizes (e.g., edge crush: 30–200 mm width; ring crush: 75–300 mm diameter).
- Quick-release fixtures for efficient sample loading/unloading.
