Device Name:Melt finger flow rate testing machine
Product model:ZBZ400AM
Performance description:The melt flow rate testing machine is a specialized equipment for measuring the melt flow rate of thermoplastic materials under certain conditions. The melt flow rate (melt index) of thermoplastic refers to the melting mass or volume of plastic passing through a standard die every 10 minutes at a certain temperature and load, expressed as MFR (MI) or MVR value. It can distinguish the viscous flow characteristics of thermoplastic in the molten state. The quality assurance of thermoplastic and synthetic fiber raw materials, products, and other products is of great significance. This machine has high temperature control accuracy, key parts undergo nitriding treatment, high strength and hardness, and small deformation, which provides good conditions for precise measurement of flow rate. This product is mainly used in factories, product quality inspection institutes, scientific research institutions and other units for the production, inspection, development, research and other fields of plastics.
