Investment Casting Benefits
Investment Casting vs. Sand Casting
The sand casting process uses sand as the molding tool, creating a sand paper appearance on the casting. It also requires additional operations such as some secondary machining.
Investment casting uses a ceramic mold that produces a smooth surface finish, while providing reliable process controls and repeatability maintained from casting to casting. The investment casting process can eliminate the majority, if not all, of the secondary machining operations.
Investment Casting vs. Metal Fabrication
Metal fabrication is building metal structures by cutting, bending and welding. It may require several pieces welded together to create a single part creating a long production time.
On the other hand, investment casting is one continuous part that offers a superior degree of accuracy and precise dimensional results in comparison. Investment casting also provides shorter lead times compared to metal fabrication.
Investment Casting vs. Machining
When machining out of bar stock there is a sizable amount of material waste. Investment casting reduces material cost because there is no material waste. Investment casting consistently holds a high degree of accuracy and precise dimensional results. This can eliminate the need for most if not all of the machining. Investment casting offers casting designs that are not obtainable in machining. Investment casting also offers a wider range of alloy choices that are not machine able.
Investment Casting vs. Die Casting
Die casting is forcing molten metal into a mold cavity. This is hard on tooling, so the mold cavity is made of hardened tool steel which is costly and time consuming to construct. Ferrous metals cannot be used in the die casting process.
Investment casting injects wax into a mold cavity this is constructed with standard aluminum which is much lower in cost and more time efficient to construct. It offers ferrous and nonferrous metals.
Investment Casting vs. Forging
Forging usually requires additional processing such as machining. Investment casting can produce parts without additional processing required to keep cost down, while holding tighter tolerances. Investment casting can also produce inter diameters such as holes and slots that the forging process is unable to obtain.
