[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, the product is precise in size, easy to upgrade, and can produce parts with complex shapes. Injection molding is suitable for mass production and other molding processes involving complex shapes. During injection molding, raw materials are typically transported via a screw pump. During processing, the raw materials need to be proportioned and prepared according to the requirements of the production process. During this process, weighing equipment is required to weigh the various materials in the raw materials.
