Temperature Control Walk In Environmental Chamber For ISTA Packaging Testing

1. Product Name and Purpose

2. Product Features

• Tailored Chamber Design for Packaging Testing
  • The chamber is constructed with dimensions and an interior layout that can accommodate a wide variety of packaging sizes and shapes. The walls are made of high-strength, durable materials that provide excellent insulation and resistance to wear and tear. The door is engineered with a precision sealing mechanism and a large viewing window, allowing operators to closely monitor the testing process without compromising the integrity of the internal environment. The interior is equipped with adjustable racks and fixtures to ensure proper positioning and orientation of the test packages.
• Precision Environmental Control Systems
  • Temperature Control: Capable of achieving a wide temperature range from -40°C to +80°C with an accuracy of ±0.5°C. The system utilizes advanced refrigeration and heating units, along with multiple temperature sensors, to ensure uniform temperature distribution throughout the chamber. This allows for testing of packaging in extreme cold and hot conditions, simulating different climate zones and storage environments.
  • Humidity Control: The humidity range extends from 10% to 95% relative humidity, with an accuracy of ±3% RH. A combination of humidifiers and dehumidifiers, coordinated by a sophisticated control algorithm, enables precise humidity adjustments. High humidity can affect the integrity of packaging materials such as cardboard and plastics, while low humidity can cause drying and brittleness, so accurate humidity control is essential.
  • Vibration System: Integrated vibration platforms can generate a variety of vibration frequencies and amplitudes, simulating the vibrations experienced during transportation, such as those from trucks, trains, and airplanes. The vibration system can be programmed to replicate different types of road surfaces and transport conditions, providing a comprehensive evaluation of the packaging's resistance to vibration-induced damage.
  • Shock and Drop Testing Capability: The chamber is equipped with a shock generator and a drop mechanism. The shock generator can produce controlled shock pulses with varying magnitudes and durations, simulating the impacts that packages may experience during handling and transit. The drop mechanism allows for precise control of the drop height and angle, enabling the assessment of the packaging's ability to protect the contents from drops and falls.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel is designed for ease of use and operator convenience. It features a clear and intuitive interface that allows operators to set and adjust parameters such as temperature, humidity, vibration frequency and amplitude, shock magnitude, and drop height with minimal effort. The control panel also provides real-time displays of the current environmental conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data. This includes temperature and humidity histories, vibration profiles, shock waveforms, drop parameters, and any observable changes in the packaging or its contents. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats.
• Safety Features and Alarms
  • Over-temperature and over-pressure protection systems are in place to prevent damage to the chamber and the test samples. Emergency stop buttons are easily accessible. Alarms are triggered for abnormal temperature fluctuations, humidity levels, vibration malfunctions, shock irregularities, or any other equipment failures. The chamber is also equipped with safety interlocks to prevent accidental operation of the shock and drop mechanisms while the door is open.

3. Specific Parameters

• Temperature Range and Accuracy
  • The -40°C to +80°C temperature range with ±0.5°C accuracy enables the evaluation of packaging performance in a wide range of thermal conditions. For example, in cold climates, packaging materials may become brittle, while in hot climates, they may soften or deform. The accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Humidity Range and Accuracy
  • The 10% to 95% RH humidity range and ±3% RH accuracy allow for a detailed study of the effect of moisture on packaging. High humidity can cause swelling, warping, or weakening of materials, while low humidity can lead to cracking and loss of integrity. Precise humidity control is necessary to understand and mitigate these potential issues.
• Vibration Parameters
  • The vibration system can produce frequencies from 5 Hz to 2000 Hz and amplitudes up to 50 mm. These parameters can be adjusted to mimic different transportation scenarios, from a smooth highway ride to a rough off-road journey. The vibration duration can also be set, allowing for long-term testing to simulate extended transit times.
• Shock and Drop Testing Parameters
  • The shock generator can produce shock pulses with amplitudes ranging from 10g to 100g (where g is the acceleration due to gravity) and durations from 5 milliseconds to 50 milliseconds. The drop mechanism can handle drops from heights ranging from 0.5 meters to 2 meters, with adjustable angles. These parameters can be customized to replicate the specific handling and transit conditions that packages are likely to face.
• Testing Volume and Payload Capacity
  • The testing volume can be customized, usually ranging from 5 m³ to 20 m³, depending on the size of the packaging to be tested. The payload capacity is designed to handle heavy and bulky packages, with a maximum capacity of up to several tons.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 1000 Hz. The temperature data has a resolution of 0.1°C, humidity data 0.1% RH, vibration data 0.1 Hz and 0.1 mm for frequency and amplitude respectively, shock data with an accuracy of ±0.1g for acceleration and ±0.1 milliseconds for duration, and drop height data with an accuracy of ±0.01 meters.

4. Product Functions

• Accurate Simulation of Transit and Storage Conditions
  • The chamber replicates the complex environmental and physical conditions that packages experience during transportation and storage. This includes temperature changes, humidity levels, vibrations, shocks, and drops. By subjecting packaging to these realistic conditions, businesses can ensure that their packages will withstand the rigors of the supply chain and arrive at their destination intact.
• Packaging Design Optimization and Quality Control
  • Through a series of tests on different packaging prototypes, the data obtained from the chamber can be used to optimize packaging designs.
