Investment Castings FAQ
Q1: What is an investment casting process?
A1: Investment casting is a manufacturing process in which a liquid material is poured into a ceramic mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is the casting, which is broken away from the ceramic mold to complete the process.
Q2: How accurate is investment casting?
A2: Quite Expensive: Investment casting is quite costly compared to other processes. This is especially true when dealing with a low volume of production. Labor Intensive: As the process is complex and involves a lot of steps, it is quite labor-intensive. So, the labor cost is high for precision casting.
Q3: Is investment casting expensive?
A3: Investment casting is preferred for its ability to produce complex and intricate parts with high precision. It offers excellent surface finishes and allows for the casting of thin-walled sections, reducing the need for secondary machining.
Q4: Why is investment casting costly?
A4: Investment casting, also known as lost-wax casting, allows for the creation of intricate and detailed metal parts. Factors that affect investment casting costs are hard tooling, casting size, casting shape, alloy material, quality requirements, dimensional requirements, and quantity.
Q5: What is the size limit for investment casting?
A5: Investment casting is used with almost any castable metal. However, aluminium alloys, copper alloys, and steel are the most common. In industrial use, the size limits are 3 g (0.1 oz) to several hundred kilograms. The cross-sectional limits are 0.6 mm (0.024 in) to 75 mm (3.0 in).
Q6: What kind of wax is used in investment casting?
A6: Paraffin wax is used to affect the rheological properties, the injection temperature and fluidity of the investment casting wax material. Microcrystalline wax is also a hydrocarbon based petrochemical produced as a by-product of the distillation of crude oil.
Q7: What products are made by investment casting?
A7: The applications of investment castings are limitless. However, the aerospace, power generation, firearm, automotive, military, commercial, food service, gas and oil, and energy industries use these metal components the most.
Q8: Why do people use investment casting?
A8: Investment casting is generally used for making complex-shaped components that require tighter tolerances, thinner walls and better surface finish than can be obtained with sand casting. The distinguishing feature of investment casting is the way the mould is made.
Q9: What is the difference between casting and investment casting?
A9: Investment casting accommodates both ferrous and non-ferrous metals, while die casting is only suitable for non-ferrous casting metals. Investment casting is ideal for low and medium-volume production runs, while die casting is more appropriate for high-volume production runs.
