Test Refrigerator Plastic for Ultra-Low Freezing

Test Refrigerator Plastic for Ultra-Low Freezing

While purchasing a new refrigerator, the customer may ask several questions about the size, colour and price of the product. However, one important aspect of refrigerators is often overlooked by the consumers, and that is – the type of plastic has been utilized in their construction. Most of the modern refrigerator designs make major use of distinct forms of plastic to deliver better performance. Refrigerator manufacturers use different types of plastic material to satisfy their requirements and design considerations. Plastic material can deliver a wide range of benefits to refrigerator manufacturers and owners. This post focuses on the quality assurance of the plastic components and materials which are used in Refrigerators, using the Ultra-low deep freezer.

Plastic parts of refrigerators are exposed to cold or freezing temperature for a long time. They need to sustain the freezing temperature and maintain their quality. Low-grade plastic material may develop cracks in them within a short period of time. At the time of manufacturing, the polymer material may seem right but one cannot guarantee the actual performance for a long run. Therefore, one must test the plastic material’s tolerance to freezing temperatures using an efficient testing equipment.

The ultra-low deep freezer is a proficient chamber which is used to imitate cold climatic conditions up to ultra-low freezing temperature. The chamber is equipped with an air-cooled compressor and CFC free coolant to deliver effective cooling with uniform air circulation.

High capacity air cooling condensers with aerodynamically shaped fans are equipped in the chamber for maintaining accuracy in temperature. The temperature range it offers ranges from -10°C to -60 °C. The entire body of the chamber is insulated using High-grade PUF insulation to assure zero heat loss. A double gasket seal also adds to the insulation of the cooling system. The temperature parameters can be programmed using the digital controls. The accuracy in the temperature is maintained using a PT-100 sensor.

Testing the plastic parts in ultra-low temperature for few hours can help you in estimating their actual working life if kept in refrigerating temperature for years. Thus, you can be sure of the plastic components you are using for your refrigerators within a shorter period of time.
