The Advantages Of Investment Casting
Feb 24, 2017

Melt die casting size precision high, General can up CT4-6 (sand type casting for CT10~13, die-cast for CT5~7), certainly due to melt die casting of process process complex, effect casting size precision of factors more, for example die material of contraction, and melt die of deformation, and type shell in heating and cooling process in the of line volume changes, and alloy of contraction rate and in solidification process in the casting of deformation,, so general melt die casting of size precision although high, but its consistency still needed improve (used in the, and High temperature wax casting size consistency a lot quicker).

Biggest advantage of investment casting is due to investment castings with high dimensional accuracy and surface finish, so you can reduce mechanical machining work, but high requirements on the part of the site remain a little machining allowance can, even some of the cast just grinding, polishing pad can be used without machining. Thus, using investment casting method can save a lot of machine tool equipment and processing time, significant savings in metallic materials.

Another advantage of investment casting method is, it can be complex castings of cast alloys, special cast Superalloy castings. Such as Jet engine blades, its sleek outline and cooling cavity, with the machining process can hardly be formed. Produced by investment casting process can not only be mass production, ensure the consistency of the casting, and avoids the stress concentration of mechanical processing residues after Knife Sheath.
