In the injection molding industry, the electrostatic treatment of injection molds and injection molded parts is very important. The electrostatic problem mainly comes from the friction and collision process of plastic in the mold. These 1 physical phenomena may not only cause the injection molded parts to adhere tightly to the mold, but also cause great inconvenience to the automatic production process. The accumulation of static electricity will seriously interfere with the automatic separation and collection process of injection molded parts, making the original smooth production line become stuck and inefficient. For the pursuit of efficient, accurate and continuous operation of the automation industry, this is undoubtedly a key issue to be solved.

The ion air knife is installed above the mold, which not only removes static electricity on the surface of the mold, but also removes static electricity on the molded injection parts. For the injection parts with relatively tight suction, the ion air knife provides 4 air inlets plus machine jitter, which can make the molded injection parts successfully fall from the surface of the mold and fall into the lower material frame.
Measuring static electricity
After installing the ion air knife, measure the static electricity of the injection molded parts falling into the material frame. Refer to the picture below. At this time, since the ion air knife has been installed, measure the static electricity of the injection molded parts falling into the material frame, and the static electricity is only about 150V.
Conclusion:

After installing the ion air knife, the stubborn adsorption problem of the injection molded parts on the mold has been fundamentally solved, so that the injection molded parts can smoothly fall into the material frame, thus effectively eliminating the potential adverse factors (NG hidden danger) in the next feeding caused by adhesion. These 1 improvements not only significantly improve the production efficiency, but also ensure the smooth progress of injection molded parts in the follow-up process, so that the product can maintain a good state in the follow-up spraying, printing, assembly and other links, creating a more ideal environment for the whole production process.
