OK-DL-150 Drop Testing Machine

Overview

The OK-DL-150 Drop Testing Machine is an electromechanically actuated, single-arm vertical impact tester engineered for standardized evaluation of transport packaging integrity under free-fall conditions. It operates on the principle of controlled gravitational acceleration, enabling repeatable simulation of real-world handling shocks—including face, edge, and corner impacts—on filled or empty shipping containers, primary packages, and unit loads. Designed in accordance with internationally recognized physical testing protocols, the system delivers traceable, reproducible drop events within a height range of 300–1500 mm, with precision height tracking via optical encoder feedback and digital LED display. Its robust dual-column frame supports stable alignment during lift, hold, and release phases, while integrated hydraulic damping ensures consistent energy dissipation across repeated cycles—critical for long-term mechanical reliability and operator safety.

Key Features

• Electromechanical lifting and release mechanism with programmable height setting and automatic reset function
• High-resolution optical encoder coupled with digital height indicator (±2% or ±10 mm accuracy per GB/T 4857.5)
• Single-arm configuration optimized for rapid sample loading/unloading and unobstructed access to impact surfaces
• Hydraulic buffer system minimizing structural rebound and extending service life of guide columns, release mechanism, and base assembly
• Adjustable impact orientation platform ensuring ≤5° angular deviation between drop surface and horizontal reference plane
• Stainless-steel impact base plate with standardized surface flatness (≤0.1 mm/m) and calibrated hardness (HRC 55–60)
• Emergency stop circuit compliant with IEC 60204-1; CE-marked electrical enclosure with IP54-rated components

Sample Compatibility & Compliance

The OK-DL-150 accommodates a broad range of packaged goods—from small consumer electronics enclosures (minimum footprint: 100 × 100 mm) to industrial palletized units (maximum dimensions: 800 × 800 × 1200 mm; max weight: 50 kg). All test configurations adhere strictly to the procedural requirements defined in GB/T 4857.5 (equivalent to ISO 2248:1985) for vertical shock testing, including pre-conditioning per GB/T 4857.2 (temperature/humidity stabilization), labeling conventions per GB/T 4857.1, and test plan documentation per GB/T 4857.17 and GB/T 4857.18. While not certified to ASTM D5276 or ISTA 3A out-of-the-box, the machine’s mechanical repeatability and height fidelity support method validation for internal quality control labs operating under GLP or GMP-aligned documentation systems.

Software & Data Management

The OK-DL-150 operates as a standalone electromechanical instrument without embedded firmware or proprietary software. All operational parameters—including target drop height, number of drops per orientation, and sequence order—are manually configured via front-panel controls. Height verification data from the digital display may be recorded externally in laboratory notebooks or LIMS-compatible spreadsheets. For users requiring audit-ready records, integration with third-party data acquisition systems (e.g., LabVIEW or MATLAB via RS-232/USB TTL interface) is supported through optional analog voltage output (0–5 V proportional to encoder position). The device meets basic requirements for 21 CFR Part 11 compliance when used in conjunction with validated electronic record procedures and user-access-controlled documentation workflows.

Applications

• Validation of corrugated box compression strength and seam integrity under simulated warehouse drop scenarios
• Qualification testing of medical device secondary packaging per ISO 11607-1 Annex B guidelines
• Comparative assessment of cushioning material performance (e.g., foam, molded pulp, air pillows) across multiple drop heights
• Root cause analysis of product damage in logistics audits, supporting corrective action reports (CARs)
• Internal QC screening of e-commerce fulfillment packaging prior to ISTA-certified lab submission
• Academic research in packaging engineering programs focusing on impact dynamics and energy absorption modeling

FAQ

What standards does the OK-DL-150 officially comply with?
It is fully aligned with GB/T 4857.5 and ISO 2248:1985 for vertical free-fall testing, and references GB/T 4857.1, GB/T 4857.2, GB/T 4857.17, and GB/T 4857.18 for ancillary test planning and conditioning requirements.
Can the machine perform sequential multi-drop tests without manual repositioning?
No—the OK-DL-150 requires manual sample reorientation between face, edge, and corner drops. It does not include automated rotation or indexing stages.
Is calibration certification included with purchase?
A factory-issued height verification report (traceable to national metrology standards) is provided; annual recalibration using NIST-traceable height gauges is recommended per ISO/IEC 17025 guidelines.
What maintenance intervals are recommended for the hydraulic damping system?
Hydraulic fluid inspection every 6 months and replacement every 24 months under typical usage (≤5 drops/day); seal integrity checks required after 10,000 operational cycles.
Does the unit support non-standard drop heights outside the 300–1500 mm range?
No—mechanical travel limits and structural safety margins are fixed at design stage; modifications void warranty and compromise compliance with GB/T 4857.5 clause 5.2.
