What to do if the insert leaks in the injection product

Metal insert injection molding is an accessory that combines metal and plastic, and is mainly used for various connecting devices, electronic devices, and so on. After the injection molding of the metal insert, what should the insert injection manufacturer find that the insert leaks in the injection product? Next, we will deal with this problem a bit bigger. This is a kind of 'open glue' condition. The main reason is that there is no adhesion between the plastic material and the metal insert. Suggestions: 1. Clean the surface of the metal sheet to avoid oil stains. 2. No release agent should be stained on the metal insert during injection molding. 3. If it does not work, apply paint on the surface of the metal insert as a transition layer. The paint has adhesion to the metal sheet and the plastic. There may also be other conditions. Therefore, you need to check on the spot, produce the products in accordance with the regulations, take multiple products and break them along the metal inserts, and observe whether there are traces of symmetrical adhesion on the surface of the metal inserts.
