How to conduct waterproof and airtightness testing on injection molded parts of automotive high-voltage connectors

December 31, 2023

In recent years, in the automotive industry, the use of plastic materials to replace expensive and heavy metal materials has gradually expanded. Some engineering plastic injection molded parts have high strength, even higher than metal, but they have advantages such as light weight and low price, which can effectively reduce the cost of component processing, assembly, and maintenance, and also make cars lightweight and reduce fuel consumption. In today's car, there are many components that use plastic injection molded parts. For example, the automotive high-voltage connector produced by Shenzhen Huanke Precision Injection Molding is a good example. For cars, every component is important, especially the qualification of plastic injection molded parts, which can also affect car safety. Therefore, waterproof and airtightness testing of plastic injection molded parts is very important. So, how do waterproof and airtightness testing of automotive high-pressure connector injection molded parts be carried out?

The waterproof level of automotive plastic injection molded parts is generally above IP65, which varies for different products. So, how do we know if the waterproof level of automotive plastic injection molded parts meets the corresponding standards? This requires the use of professional waterproof testing equipment for automotive plastic injection molded parts for waterproofing and airtightness testing. Waterproof and airtightness testing methods for automotive plastic injection molded parts: Based on the products to be tested for waterproofing and airtightness, determine whether a testing fixture is needed. If it is an open semi-finished product, use the direct testing method. According to the structure of the product, a fixed fixture is made, and the product is placed on the fixture for direct inflation; If it is a relatively sealed product, indirect testing methods should be used for waterproof and airtightness testing of automotive plastic injection molded parts. It is necessary to customize a testing fixture according to the appearance of the product. After the internal cavity is sealed, the product is just placed and connected to the testing port of the automotive plastic injection molded parts waterproof testing equipment. After setting the parameters, the testing can be carried out.
