The sealing surfaces of a smartwatch body are distributed across the screen bonding ring, crown and button shafts, speaker and microphone waterproof membranes, charging contacts and other locations. F···
An electronic water pump consists of a motor cavity, an impeller cavity and an electronic control cavity, and relies on a shaft seal and O-rings to keep coolant out of the motor.
A respiratory mask is both a sealing component and a functional component. Leakage in the mask cavity or abnormal valve opening and closing directly affects ventilation performance and oxygen concentr···
Automotive camera modules are small in size and contain optical elements and circuits inside. A micro-leak at the lens barrel adhesive joint or the housing seal ring will let moisture condense on the ···
The interior of an on-board charger (OBC) housing contains high-voltage power circuits. Water ingress at any point—the upper and lower cover sealing rings, the high-voltage terminal through-holes, or···
Control boxes and PDU housings integrate busbars, relays and fuses inside; a housing sealing failure allows moisture ingress and causes creepage, short circuits and contact oxidation.
The sealing of a syringe barrel depends on the sliding seal between the barrel and the plunger rubber stopper; failure can cause inaccurate dosing or even leakage of the drug solution.
Energy storage battery cabinets are exposed to outdoor and coastal environments over the long term. Once a weld seam, explosion-proof valve or liquid cooling connector develops a micro-leak, moisture ···
The medical catheter connector (catheter hub) is the bonded or heat-fused joint between the catheter and the Luer connector or extension tubing. A micro-leak at the joint surface causes fluid leakage ···
