AI Technical Summary
Existing injection devices cause air bubbles to be mixed into the material during the injection process, which affects the molding quality and physical properties of silicone frames and is prone to supply interruptions.
The system employs a stirring rod, turning blades, and feeding screw inside the storage tank, along with an electric heating rod and a vacuum pump. By stirring and venting air bubbles, it ensures that the material is sealed and in a vacuum state before injection, thus avoiding interference from air bubbles.
It effectively reduces the air content inside the material, ensures a stable injection process, improves the molding quality of silicone frames, prevents supply disruptions, and guarantees the product's appearance and physical properties.
