Investment Casting
Investment casting, also known as lost wax casting or precision casting, is a casting technology that can produce near-net-shape parts. This technology is applicable to almost all types of metal materials, including but not limited to the following:
1. Stainless steel: strong corrosion resistance, commonly used in medical equipment, food processing equipment, chemical equipment and other fields.
2. Carbon steel: has good mechanical properties and processing properties, widely used in the manufacture of various mechanical parts and structural parts.
3. Alloy steel: by adding different alloying elements, such as chromium, nickel, molybdenum, etc., to improve the specific properties of steel, such as heat resistance, wear resistance, etc.
4. Aluminum alloy: light weight, high strength, good thermal and electrical conductivity, commonly used in aerospace, automobile, electronics and other fields.
5. Titanium alloy: has high strength, low density and good corrosion resistance, often used in aerospace, medical equipment and other fields.
6. Copper alloy: including brass, bronze, etc., has good electrical and thermal conductivity, often used in the manufacture of electrical equipment and heat exchangers.
7. High-temperature alloys: They have excellent high-temperature strength and oxidation resistance, and are suitable for manufacturing parts that work at high temperatures, such as gas turbine blades.
8. Cobalt alloys: They are known for their excellent wear resistance and corrosion resistance, and are often used to manufacture cutting tools and artificial joints.
9. Magnesium alloys: They are lightweight, high-strength, and have good shock resistance, and are often used in aerospace and automotive lightweight parts.
10. Zinc alloys: They have good casting properties and low costs, and are often used to manufacture small parts and decorations.
11. Lead alloys: They have good X-ray shielding properties and are often used as shielding materials in the medical and industrial fields.
12. Precious metal alloys: Such as gold and platinum, they are often used in jewelry manufacturing and certain special industrial applications.
The reason why investment casting technology can be applied to such a wide range of metal materials is that its precise casting process can control the flow and cooling of molten metal, thereby achieving precise control of material properties. In addition, investment casting can also further optimize the performance of the material through post-processing, such as heat treatment and surface treatment.
