Advantages of lost wax Process:

The investment casting process offers many benefits including cost reduction, design flexibility, close tolerances, better finishes,machining and assembly time reduction and higher reproductive capability.

●  Lower initial tooling costs:

     Initial tooling costs for the lost wax casting process are often lower than other casting processes.

●  Elimination of material waste:

     Investment castings are essentially cast to size, thus reducing the amount of machining time.

●  Design flexibility and capability:

     Infinite choice of alloys and design flexibility for internal and external configurations are seen as the extra point.

●  Design enhancements:

     There are no draft requirements in the investment casting process.

●  Consistency:

     The process offers reliable and consistent product quality from order to order.

●  Close Tolerances:

     Consistently producing more close tolerances over other processes is seen as an advantage.

●  Surface Finish Improvement:

     A surface finish of about 125 RMS is insured for an investment casting.

If your demand is for a single piece to reduce assembly and re-assembly time; If your desire to eliminate the cost of fabrication and reduce the use of welding; If you see the use of an as-cast part as desirable by reducing the machining time, the choice of an investment casting would be a wise decision for lowering the production cost.
