The tip of the hot runner is an inseparable key component in the hot runner system. The selection of the hot runner can lead to the service life of the hot runner in the mold. Thermal conductivity, abrasion resistance, and corrosion resistance are the keys to selecting materials. Below we will subdivide the advantages and disadvantages of various materials of the hot runner.
It can choose different alloy materials according to the characteristics of processed plastics to meet the requirements of plastic temperature, acid corrosion and wear on the tip of the mouth. The tip of the hot runner is the key component that combines the hot runner with the mold cavity, and plays a key role in the thermal closure of the runner gate. At present, beryllium copper, molybdenum alloy, and tungsten steel are generally used as the tip of the hot runner. Due to the different physical properties of the material, there are many deficiencies.
Although the life of the tip is longer than that of copper beryllium, each material has its advantages. Of course, it also has a lot to do with the overall application and technology of the hot runner. Material defects such as wear resistance, corrosion resistance, high temperature and easy oxidation, but the molybdenum alloys produced by most manufacturers are not completely suitable for the hot runner industry due to performance problems, but the American standard beryllium copper developed by our company can meet the above requirements. Molybdenum alloy is a late slow-heating material, waiting for the results of the entire market.
