Metal punching - Import export

Creating an optimal bond between a metal plate and the silicone: that was the challenge Enbi Plastics was given by Océ Technologies, a major player in printing and copying equipment. They needed a new wiper assy; a part on the print head that prevents streaks on the paper. Because this part needs to be somewhat flexible, silicone needed to be added to a small, punched metal plate, to which screw thread is welded. This construction did not allow for a mechanical bond between the metal and silicone, which meant chemical bonding was the only option. Together with the client, the mould supplier, the silicone supplier and others, we did extensive research into the best way to achieve this bond. It showed that preparing the small metal plates was the key. After several tests, we discovered the optimal way to do this. A number of factors play a role: from how to clean and sand the plate to humidity, temperature and the time in between the steps of the process. Every detail counts!
