With the development of the economy, both consumers and producers have increasingly higher requirements for product quality, and people's requirements for the sealing properties of wires are also constantly increasing.In order to obtain the highest performance of wire products, manufacturers will conduct sealing testing on wires. However, different types of wires have different requirements for sealing testing, which is also one of the difficulties in wire sealing testing.As a well-known sealing testing and production expert, Hairis Technology has always made great achievements in wire sealing testing. So, this time we will share a wire sealing testing case for your reference.

1. The overall situation of the wire

1. The wire has strong plasticity, high softness, and is easy to fold, making it difficult to directly detect;

2. The entire wire is in the shape of an irregular long strip, and the connectors at the front and rear of the wire are irregular cylinders;

3. The connectors at the front and rear ends of the wire are exposed to ensure use, which can easily lead to gas leakage during testing;

4. In order to achieve sealing performance, manufacturers in the lower part use sealing rings and overall glue filling at the joints to isolate the intrusion of external substances. The leakage value is small and it is difficult to monitor the data;

2. Faced with the overall condition of the wire, how to conduct sealing testing for the wire?

Hairis Technology will customize a mold tooling according to the overall condition of the wire. The mold can be held according to the softness of the wire, and a groove is specially made to better fix the connectors at the front and rear ends of the wire, so that the upper and lower parts of the mold can be better sealed when closed.

Put the wire connector into the tooling mold and connect it to our instrument. There is a valve island, gas tank and other components inside the instrument as well as the program we have set. After the connection is made, press the start button when testing the wire.

During inspection, the instrument will inflate the mold.If the wire connector is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the wire connector is leaking, and the instrument test result will also show NG, which means the air tightness test failed.If the tested wire connector does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the air tightness test has passed.
