ASTM D642 / ISO 12048 Package Compression Tester

The LS-PUSH-600 package compression tester performs standardized compression resistance and pressure holding capacity tests on packaging materials and cartons in accordance with international testing protocols. This equipment provides critical data for packaging design optimization and finished product stacking height planning in industrial applications.

This system employs a high-precision transmission mechanism with a stable control architecture, applying uniform compressive force to test specimens through adjustable compression velocity parameters. The instrument accurately captures key performance metrics including peak load and average load during testing sequences, with configurable pressure holding duration to simulate stacking pressures encountered during storage and transportation cycles.

The equipment incorporates multiple safety protection systems to ensure testing process integrity and operational reliability. Test data recording and storage capabilities provide objective, quantifiable support for product quality assessment and compliance verification.
