Compression Tester
This electromechanical compression tester is designed to evaluate the compressive strength and creep behavior of packaging and unit loads. It simulates real-world vertical forces during storage and transportation, providing accurate, repeatable results. Fully compliant with international standards like ASTM, ISTA, and ISO, it ensures packaging reliability and safety.
Built to replicate real-world compressive forces, compression testers are designed to protect products, validate packaging strength, and ensure safe delivery throughout the supply chain.
Compression testers are specifically engineered to evaluate the strength, stability, and durability of packaging and unit loads when subjected to vertical and lateral compressive forces during handling, automated warehousing, and transportation.
By replicating both standard test protocols and real-world load conditions, these systems accurately simulate the stresses that products experience throughout the distribution cycle.
- Compression frame: A rigid four-column structure ensures alignment and minimizes deflection during high-load tests, providing mechanical stability for long-term use.
- Servo-controlled actuation system: Driven by a servomotor and dual ball screws, the system delivers controlled vertical motion with adjustable speed and high positioning accuracy.
- Modular platen system: Includes both fixed and floating platens, with the floating version equipped with a spherical joint to simulate realistic contact conditions and compensate for sample irregularities.
- Force measurement platform: Equipped with multiple high-precision load cells under the test surface to monitor applied forces across the entire contact area.
- Integrated safety features: Includes emergency stop buttons, proximity sensors to limit platen travel, and provisions for safety fencing with interlock systems compliant with CE regulations.

Core strengths of the innPress and the compression tests that drive packaging validation
This testing solution empowers engineering and packaging teams to proactively identify load-bearing limitations and optimize structural design based on real compression behavior. Rather than relying on theoretical models, users gain actionable data that supports leaner packaging, safer stacking, and improved long-term reliability.
Tailored for high-stakes applications, the innPress integrates seamlessly into validation workflows in industries where failure is not an option—such as aerospace, medical devices, and electronics. Its robust design and configurable platform make it a critical asset for ensuring supply chain continuity and protecting product value under pressure.
Real-world compression force simulation
Real-time monitoring of force and displacement generates precise deformation profiles, while the intuitive control software includes preset modes such as vertical compression, apply and hold, apply and release, box compression test (BCT), and creep. This enables fully automated testing sequences with minimal operator intervention and maximum repeatability.
Creep testing for long-term performance evaluation
Equipped with dedicated creep characterization modes, the Compression Tester performs extended-duration tests to analyze how packaging deforms under constant load over time. This functionality is crucial for assessing whether packaging maintains its structural integrity during prolonged storage or in high-stacking environments. The automated data collection and precise load control deliver detailed deformation curves essential for material optimization and compliance with ISO 8611 and ASTM D4169.
Advanced data acquisition and analysis
The compression tester integrates high-precision load cells, inductive proximity sensors, and a spindle-driven transmission system to ensure exceptional measurement accuracy. It offers a load accuracy of up to ±0.2% relative to full scale and a maximum measurement error of ±1% across the working range. Equipped with a C3 load cell — upgradeable to C5 or 00 for greater precision upon request — the system provides reliable and repeatable results.
Versatile compatibility for multiple load types
Thanks to configurable platform sizes of up to 1500 x 1500 mm and stroke lengths reaching 2100 mm, the machine easily adapts to diverse testing needs. It supports reliable testing of small containers, shipping boxes, retail packaging, unit loads, and full pallets without compromising measurement accuracy. This versatility is particularly valuable for companies handling mixed product lines, as it ensures that both light packaging and heavy palletized loads can be validated using a single system.
Expanded testing capability with dedicated accessories
To further enhance testing flexibility, Safe Load Testing Technologies offers optional accessories that expand the system’s capabilities. The table to lower compression range enables accurate testing of lighter loads and smaller packages by extending the compression range downward, allowing highly precise compression tests on a broader variety of packaging types, from small consumer goods to lightweight unit loads. Additionally, the ISO 8611 accessories for pallets are specialized fixtures designed to perform fully compliant pallet compression tests according to ISO 8611 standards, ensuring reliable and repeatable results when evaluating the structural strength and stability of pallets under realistic loading conditions.
