Modern technological methods make it possible to manufacture final parts directly by casting aluminum, zinc and magnesium alloys into prepared molds. In this case, the necessary parameters of such parts may have:
- Complex geometries, including radii.
- Internal cavities, as well as through or non-through holes or recesses.
And if everything is extremely simple with the external criteria, they are set using special forms where the molten alloy is poured. Then for the formation of internal (through, with a varying radius or curvature) cavities at the metallurgical enterprise "Vikom-VILS", the technology of using special casting rods is used, for more details see http://vicomdisk.ru/uslugi/alyuminievoe-lityo .
Method of production and use
Casting rods are made by molding from a sand mixture with the addition of binders (synthetic resins, water glass). To form more complex internal cavities, the so-called layout method is used using several sandy parts, which are glued together directly when installed in a mold for casting a future part.
Installation of casting cores is carried out using the special protrusions available on them, which are combined with the mold grooves during installation. To remove gases formed during pouring molten metal, they are pre-pierced with a needle until through holes are formed.
