1. During the aluminum alloy profile extrusion die trial and aluminum extrusion process, the following aspects should be paid attention to:
A. Determine the mold temperature and rod temperature before extrusion of aluminum alloy profiles, whether it meets the extrusion temperature requirements, and whether the heating is through the core (the placement of the mold in the heating furnace is very important, and there must be a certain heating gap between the molds).
B. The aluminum extrusion mold must be aligned with the center to avoid collapse and mold plugging.
C. For different aluminum alloy profile molds, appropriate extrusion speeds should be selected to avoid being too fast and causing poor discharging.
D. During the extrusion process of aluminum alloy profiles, we must also pay attention to the quality of the aluminum rod to avoid mold collapse due to impurities in the aluminum rod.
2. Aluminum extrusion mold repair is a very important step, but the first thing to consider when repairing the mold is its strength. The mold repair must be carried out on the basis of ensuring the strength of the aluminum extrusion die. Welding is generally not used until the final level, because welding has a significant impact on the life of the mold. Especially the welding of the work belt can easily shorten the service life. For the repair of profile speed, it is generally used to repair the slow parts to make them faster rather than to slow down the fast parts. At this point, the burden on the mold structure has been reduced, and its lifespan can be guaranteed to a certain extent. Of course, improving the level of mold repair and reducing the number of mold trials is also one of the ways to increase the service life of the mold.
3. During the mold making process, special attention should be paid to the removal of punching materials, especially in some screw holes or relatively fragile places, otherwise, the mold will be easily broken.
4. The handling process of aluminum extrusion molds must be carried out carefully to avoid bumping into work belts and other places. Before the mold is put into the warehouse, it must be cleaned and inspected carefully and thoroughly to see if there are any small cracks and damage.
5. The process data of the finished mold must be effectively managed, such as the mold repair plan, processing details, extrusion process, etc. Because these can become the copy objects of subsequent supplementary molds or similar molds, this can effectively improve the mold's machine qualification rate.
In short, the improvement of extrusion die life depends on the perfect link between design, manufacturing, use and subsequent maintenance. Relying on a single link cannot effectively achieve the goal. Through the effective integration of each link, I believe that the mold life can be improved accordingly.
