NES M0132 Vibration Thermal Cycle Test Chambers For Plastic Parts

1. Product Name and Purpose

2. Product Features

• Tailored Chamber Design for Plastic Part Testing
  • The chamber is constructed with dimensions and an interior layout that are optimized to house the specific “NTC-1-5A” plastic parts. The walls are fabricated from high-strength, thermally stable materials that provide excellent insulation and durability. The door is engineered with a precision sealing mechanism and a large viewing window, allowing operators to closely monitor the testing process without perturbing the internal environment. The interior is equipped with adjustable racks and fixtures, ensuring proper positioning and uniform exposure of the plastic parts to both thermal cycling and vibration.
• Precision Temperature and Vibration Control Systems
  • Temperature Cycling Capability: The chamber can achieve a wide temperature range, typically from -40°C to +120°C, with an accuracy of ±0.3°C. It is furnished with a high-performance refrigeration unit and powerful heating elements, coordinated by a sophisticated control algorithm and multiple temperature sensors. This enables the chamber to execute precise and rapid temperature cycling, replicating the harsh thermal environments that plastic parts may experience, such as in extreme weather conditions or near heat sources.
  • Vibration System: The chamber is outfitted with a high-precision vibration platform that can generate a wide spectrum of vibration frequencies and amplitudes. It can produce vibrations from 5 Hz to 2000 Hz with amplitudes up to 50 mm. The vibration system is designed to mimic various real-world vibration sources, including machinery vibrations, transportation-induced jolts, and the dynamic forces associated with product usage. The vibration control system offers remarkable accuracy, allowing for the programming of complex vibration profiles and real-time adjustments.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel is crafted for user-friendliness, affording operators effortless access to all test parameters. They can readily set and adjust temperature limits, cycling times, vibration frequencies, amplitudes, and test durations. The panel also presents real-time information regarding the current temperature, vibration status, and any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all pertinent test data. This encompasses temperature histories, vibration waveforms, and any observable changes in the physical or mechanical properties of the plastic parts. The data can be stored in a built-in memory or exported to external storage devices for in-depth analysis. The system is also capable of generating detailed test reports in various formats.
• Safety Features and Alarms
  • To safeguard operators and the integrity of the testing process, a suite of safety features is incorporated. These include over-temperature and over-vibration protection systems, emergency stop buttons, and alarms for abnormal temperature fluctuations, vibration malfunctions, or any other equipment failures. The chamber is also equipped with proper ventilation and exhaust systems to handle any potentially harmful gases or vapors that may be emitted from the plastic parts during thermal cycling and vibration testing.

3. Specific Parameters

• Temperature Range and Accuracy
  • The -40°C to +120°C temperature range with ±0.3°C accuracy offers a comprehensive and precise testing environment. This wide range allows for the evaluation of plastic parts' performance under both extremely cold and hot conditions. Different plastic materials have varying glass transition temperatures and thermal expansion coefficients, and this accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Vibration Parameters
  • The vibration system's ability to produce frequencies from 5 Hz to 2000 Hz and amplitudes up to 50 mm provides a thorough assessment of the plastic parts. Low-frequency vibrations can mimic the slow oscillations of a product during storage or transportation, while high-frequency vibr
