How to Refill HP 45A TIJ Cartridges: Vacuum-Filling and Metal Ball Sealing

In this video, we demonstrate the complete process of: 1. Refilling an HP 45A TIJ ink cartridge. 2. Sealing the metal ball into the refill hole with precision. The HP 45A TIJ is one of the most widely used cartridges in industrial coding and marking printers. Because these cartridges feature internal air bladders, maintaining the exact air pressure balance during the refilling process is critical for performance. To solve this, we have integrated our Exclusive "Vacuum-Filling" System into our latest machinery. This allows for refilling under a controlled vacuum, ensuring the internal pressure balance is perfectly maintained. Additionally, our new specialized apparatus allows the metal ball to be sealed securely into the filling hole—all in one seamless process without any leaks or pressure loss.
