How to avoid product adhesion during the stamping process of N95 aluminum nose wire

2021/03/13

The aluminum nose bridge wire used in the production of N95 masks is stamped by a die-casting machine, and can be produced with a reasonable release agent, which can avoid many problems and increase production.


       N95 aluminum nose wire is made of aluminum material coil. The supplier of N95 aluminum nose wire pre-coats a layer of environmentally friendly hot melt glue on its bottom surface, and then punches it with a die-casting machine. Due to the high cost of equipment and molds, some small processing plants are reluctant to buy more products, but hope to increase production. Then, the method is to increase the punching speed from 4 times per second to 6 times per second. In such a high-speed stamping process, the mold generates high heat, which will cause the metal chips during the stamping process to adhere to the mold, and most stamping products will also stick together and be difficult to separate. The metal shavings stuck to the mold will affect the subsequent stamping effect, and the surface of the finished product will appear flaws, and even more uneven pits will appear.

 

The release agent of N95 mask aluminum nose bridge wire is a functional substance between the mold and the finished product. The release agent has chemical resistance and heat resistance, and can be bonded to the mold without transferring to the processed product. If the mold release agent can be used reasonably, the above-mentioned metal chip and product adhesion problem can be easily solved, which can greatly increase the output.
