Custom Thermal Shock Chambers for Consumer Products and Cosmetics: Elevating Product Quality and Reliability

1. Product Name and Purpose

2. Product Features

• Durable and Hygienic Chamber Construction
  • The chamber is constructed using high-quality, corrosion-resistant materials that can endure the rigors of repeated thermal cycling. The exterior is typically made of robust steel, providing excellent protection and stability. The interior is lined with a smooth, non-reactive surface that is easy to clean and maintain, ensuring that there is no contamination or interference with the tested products. The chamber's size and layout can be customized to accommodate various product sizes and shapes, with adjustable racks, shelves, and holders for efficient sample placement.
• Precision Temperature Control System
  • Temperature Range and Cycling: Capable of achieving a wide temperature range, usually from -50°C to +100°C. The system can execute rapid temperature cycling between the hot and cold zones, with a transition time as short as a few seconds. This is essential for simulating the sudden temperature changes that products may experience in real-world scenarios, such as when a cosmetic is exposed to the heat of a car in summer or the cold of a warehouse in winter. The temperature control is highly accurate, with an error margin of within ±0.5°C, ensuring reliable and reproducible test results.
  • Programmable Temperature Profiles: The chamber's control panel allows for the creation and execution of complex, custom temperature profiles. Manufacturers can define specific temperature sequences, dwell times in each zone, and the number of thermal shock cycles to replicate different environmental conditions. For example, a cosmetics company can simulate the temperature changes that a lipstick might experience during a year, including the heat of a store display and the cold of a consumer's purse.
• Intuitive User Interface and Data Acquisition
  • The control panel is designed for user-friendliness, enabling both technical and non-technical personnel to operate the chamber with ease. It provides a clear display of the current temperature in both zones, the status of the testing process, and any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system that records all relevant test data, including temperature histories, cycle times, and any observable changes in the physical or chemical properties of the products. The data can be stored in the chamber's internal memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating documentation and communication of test results.
• Enhanced Safety and Protection Features
  • To ensure the safety of operators and the integrity of the testing process, the chamber is equipped with multiple safety features. These include over-temperature and over-current protection systems, which automatically shut down or adjust the chamber if the set limits are exceeded. There are also emergency stop buttons and alarms that alert users in case of any malfunctions or abnormal conditions. The chamber door is designed with a reliable locking mechanism to prevent unauthorized access and maintain the stability of the internal environment. Additionally, it has proper ventilation and exhaust systems to handle any potentially harmful gases or vapors that may be generated during testing, such as those from cosmetic ingredients or electronic component degradation.

3. Specific Parameters

• Temperature and Thermal Shock Parameters
  • The chamber is engineered to provide excellent temperature uniformity throughout the testing volume. The temperature variation within the chamber is typically within ±1°C, ensuring that all samples are exposed to consistent thermal conditions. The number of thermal shock cycles can be adjusted according to the specific needs of the product, ranging from a few dozen to several thousand. The dwell time in each temperature zone can also be customized, from minutes to hours, allowing for a comprehensive evaluation of product performance under different thermal stress durations.
• Testing Volume and Payload Capacity
