What Is an Investment Casting?

-
Investment casting refers to the ceramics formed around the wax patterns to create a casing for molten metal to be poured. Once the wax patterns are created, they are melted onto a gate system, dipped into slurry and sand to form a layered casing, then replaced with the melted metals such as stainless steel, aluminum, and much more.

What Are Lost Wax Investment Castings?
By injecting wax into a permanent-molding die to form wax patterns, investment casting are the solution for many complex parts that are required in large quantities. We produce investment castings in lost wax patterns from a few grams up to 40 pounds, and can economically produce low quantities with manual tooling, or high volumes utilizing multi-cavity automatic molding tools.
People often say Lost Wax Casting , Water Glass Casting , both are belong to Investment Castings.Below are some materials we often used :
| Alloy | Common Usage | Applications |
| 304 | Food grade steel, housings, bodies304 is widely accepted in the food industry as the standard for cleanliness as well as corrosion resistance. | Medical Mining Petrochemical |
| 304L / 316L | Similar to other 300 series steel, the “L” stands for low carbon, making it softer but more corrosion resistant for each grade of material. | Food & Dairy Medical Petrochemical |
| 316 | Housings, gears, plates 316 is known for its superior corrosion resistance, making it ideal for many uses including marine environments. | Automotive Petrochemical Food & Dairy |
| 2205 | Pool Fencing, Stairs, Housings 2205 duplex stainless steel are high strength, thermostable, anti-corrosive, often used for ocean glass railing system . | Ocean, Outdoor, Balcony |
| 410 & 416 | Housings, bushings, handles, brackets 400 series steels are high strength and very machinable. They will tend to break rather than bend under intense pressure. | Automotive Machine Tool Food & Dairy |
| 17-4 | Rods, pins, links, arms 17-4 is the strongest of the stainless steel family and is used on parts that cannot bend. | Military Medical Machine Tool |
