How to improve the quality of die produced by extruder factory?
We usually divide the aluminum extrusion press into three parts: the main cylinder, the medium plate (extrusion barrel) and the extrusion rod. Its main cylinder is a hydraulic device. The hydraulic oil is transmitted to the small piston through the large piston to push the extrusion rod. The heated aluminum rod is pushed into the extrusion barrel. When the exhaust pressure is reached, the extrusion barrel retreats and exhausts, and then moves forward to join with the die cavity. When the extrusion pressure is reached, the extrusion rod is the same The aluminum in the extrusion barrel is fed into the diversion hole of the die, and the aluminum alloy flows out slowly through the mold.
With the increasingly fierce competition in the aluminum alloy profile market, many aluminum alloy profile production companies produced by extrusion press factories have invested infinite energy in the acquisition, application, maintenance and management of kneading dies. This is an excellent scene. However, to improve the aluminum profile extrusion die, we should pay attention to the details, do a good job in statistical analysis and cost management of the die, so as to seize the opportunity 。
In the actual production, some molds can not reach the expected output value when kneading, and the extrusion plant is faced with severe problems, even kneading less than 20 bars or using the machine less than 2 times, so that the die made of expensive die steel can not achieve its due benefits. This phenomenon is prevalent in many domestic aluminum profile production companies, which not only causes a lot of problems Economic losses, more waste of power.
To optimize kneading process, it is necessary to extend the life of the mould scientifically. It is an aspect that can not be ignored that the extrusion plant needs to reasonably use the mold for production. Because the working conditions of the kneading mold are extremely bad, reasonable methods must be adopted to ensure the function of the mold arrangement in the kneading production. It is necessary to carry out reasonable surface nitriding treatment process for the mold in the early stage of application of kneading mold. The surface nitriding treatment can greatly improve the surface hardness of the die while maintaining enough durability, so as to reduce the thermal wear of the die during operation.
