Dense-tooth radiator aluminum profiles must use special processes and design and manufacture special molds to extrude successfully. Small processing plants do not have this condition. The mold material of dense-tooth radiator profiles must be made of high-quality, high-strength, heat-resistant alloy steel, and must be forged, pretreated, and tested. The mold hardness should not be too high and should not be nitrided.
According to the mold shape and technical requirements, special guide molds, wide-angle molds, and plane combination molds are used to accurately calculate and locate the structure and size of each size part, such as the working belt, outlet belt, wide angle, and guide mold size. All should be accurately designed to accurately distribute the metal flow and speed. In addition, the mold must be in place as designed and the tolerance must be guaranteed. When producing such radiator profiles, mold repair and extrusion control are also very important.
