AI Technical Summary
The existing testing of plastic liners for four types of hydrogen storage cylinders suffers from problems such as inconsistent standards, distorted measurement data, low testing efficiency, high cost, and damage to structural integrity. In particular, errors after the valve seat is pressed into place have a serious impact, making it impossible to meet mass production requirements.
An integrally injection-molded annular measuring reference surface is used as a dedicated measuring reference for the plastic inner liner body. It is used for testing after injection molding and before pressing, avoiding the influence of bottle valve seat pressing errors, simplifying the testing process, and improving accuracy and efficiency.
It enables rapid full-size inspection of plastic liners, improving inspection accuracy and efficiency, reducing production costs, ensuring structural integrity and sealing reliability, and preventing defective products from flowing into the next process.
