In the process of both injection and extrusion, plastic material weighing is crucial and there are three methods: volumetric, weight addition, and gravimetric methods. Among all these three methods, a gravimetric method is the optimal calculation of weights for weight detection, feeding control, connection with the main instrument, smart management, and other operation. This method can control the ratio of the mixture of plastics resin, powder, additive, and other critical elements, offering a reliable feeding quality of feeding for injection molding machines and extrusion machines.

a-max has dedicated a lot of resources to the development of gravimetric equipment that is in accordance with international technology and introduces the accurate feeding mechanism into the primary manufacturing machines. Together with multiple working station designs, we can put different formulas at the same duration for the mixture and render the perfect ratio. The accuracy reaches five thousandths.
