    1. Investment Casting
    2. Investment CastingInvestment casting is a metal casting technique called lost wax casting, in which a wax pattern is used to shape a ceramic mold for creating metal parts. It is also commonly known as precision casting process due to its ability for manufacturing metal components with high accuracy and smooth surface finish.
    1. Precision Machining
    2. Precision MachiningHigh precision machining is a manufacturing process that turns raw materials into precise components with very tight tolerances and high-quality surface finishes. Precision machining processes normally are turning, milling, drilling, boring, gear cutting, honing, grinding and other operations.
    1. Sand Casting
    2. Sand CastingSand casting, also referred to as sand molding casting because it is a metal casting process using compressed sand as the mold material. The process involves the pouring of molten metal into the sand mold where it solidifies in the mold cavity.
    1. Die Casting
    2. Die CastingDie casting is an automated casting process that forces molten metal into a mold under extreme pressure and at a high speed. It is an economical and efficient way to produce large quantities of complex-shaped parts with high precision.
    1. 3D Printing
    2. 3D Printing3D printing is a cost-effective and efficient process for creating three dimensional solid objects by adding layers of materials using computer-aided design (CAD), so it is also referred to as additive manufacturing.
