For light-weight injection molded parts, static electricity can cause some unique problems for high surface-to-weight ratio injection molded parts. For example, hollow, thin-walled injection molded parts like disposable syringes and other medical products. These problems include: adhesion on the mold surface, adsorption on the conveyor belt, messy injection molded parts, etc. To address these problems, Long's has developed a lightweight solution for your electrostatic injection. Bonding on the mold surface Injection molding on the mold Surface without falling into the collection system. The reason is that the surface area of the injection molded part is large, and static electricity generates a strong adsorption force.
The solution is to blow an ion current from above the mold when the mold is opened, which will neutralize the static electricity of the injection molded parts in the mold. The static elimination system can choose ion air knife or ion air nozzle, and use solenoid valve to control air flow.
The static electricity adsorbed on the conveyor belt causes the injection molded parts to be adsorbed on the conveyor belt without falling into the collection box.
Messy injection parts Electrostatically charged injection parts can cause electric shock to operators and attract dust. Too much static electricity can cause the injection molded part to jump out of the container box. The solution to these problems is to install a controllable static eliminator (or other long-distance static eliminator), which will neutralize static electricity and make the injection molded part fall into the device.
If the product is flat and there is static electricity between the mold and the conveyor belt, the use of ion bars is not always successful. The best way is to install an ion wind rod. The gentle ion wind will prevent the product from falling into the product collection box as the conveyor moves.
