What metals are used in investment casting?
Lost Wax casting or Investment Casting can be integrated with a variety of metals and alloys such as carbon steel, stainless steel, aluminium, brass, bronze, copper, zinc and super-alloys such as Inconel and Hastelloy.
What is investment casting What are the main materials used for making the investment pattern?
The term “invested” historically carries the meaning of “clothed” or “surrounded.” Investment casting employs a shell made of ceramic, plaster, or plastic that is formed around a wax pattern. The wax pattern is melted and removed in a furnace and metal is poured into the shell to create the casting.
Which of the following products is mostly produced by precision investment casting?
So the jewellery and surgical instruments are produced easily in the investment casting. Other products like vanes and blades for a gas turbine, shuttle eyes for weaving, wave guide for radars and impellers for turbo chargers can also be produced.

- White Iron.
- Ductile Iron.
- Stainless Steel.
- Carbon Steel.
- Copper-Based Alloy.
- Nickel-Based Alloy.
What is another name for investment casting?
Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mold.
What are types of casting?
10 types of casting process
- （1）Sand casting.
- （2）Investment casting.
- （3）Die casting.
- （4）Low pressure casting.
- （5）Centrifugal casting.
- （6）Gravity die casting.
- （7）Vacuum die casting.
- （8）Squeezing die casting.
Which casting is best for mass production?
The mass production of die-cast aluminium products is automatised and computerised, and therefore lends itself to high productivity. The constant control of the casting process ensures the best possible quality of die-cast parts and maximises the production efficiency of their plants.
Why is investment casting an expensive method?
Compared to other methods of metal casting, investment casting involves many complex steps making the process relatively expensive. But some of the steps can be automated for certain products. It can be more expensive than die casting or sand casting, but per-unit costs decrease with large volumes.
What are the main advantages and disadvantages of investment casting?
Advantages and disadvantages of investment casting
- Excellent surface finish.
- Tight dimensional tolerances.
- Complex and intricate shapes may be produced.
- Capability to cast thin walls.
- Wide variety of metals and alloys (ferrous and non-ferrous) may be cast.
- Draft is not required in the molds design.
- Low material waste.
What are the advantages and disadvantages of investment casting?
Advice
| Investment Casting vs Sand-Casting | |
| Sand Casting | |
|---|---|
| Advantages | Low cost in small volumes. Not limited by size. Easy to change part design. |
| Disadvantages | High cost in large production runs. Parts are less complex. Lower dimensional accuracy. Surface finish requires additional work. |
Why wax is used in investment casting?
Runner wax blends are used by investment casting companies when desiring exceptional mechanical strength and lower viscosity. This type of wax has a lower melting point than pattern waxes. So it will drain completely out of the ceramic mold during the dewaxing process without the need to use higher temperatures.
Why are refractory materials used in investment casting?
The material is poured into a cavity in a refractory material that is an exact duplicate of the desired part. Due to the hardness of refractory materials used, investment casting can produce products with exceptional surface qualities, which can reduce the need for secondary machine processes.
How is investment casting used in Reliance Foundry?
Investment casting is used to create parts with superior dimensional accuracy, where finished forms are often produced without secondary machining. Reliance Foundry works collaboratively with clients to design the pattern and molding method for each custom casting.
Why are steel foundries more hazardous than ferrous foundries?
Nonferrous foundries and steel foundries may produce hazardous waste because of the lead, zinc, cadmium and other metal present in the waste. Cupola furnaces produce more air pollution than induction furnaces due to coke use and sand castings produce more solid waste than permanent molds because of the sand fines that cannot be reused.
How many people work in iron and steel foundries?
Although the large iron and steel foundries produce billions of dollars in metal each year and provide many jobs, most foundries have far smaller budgets and employ less than 100 people. The first step in metal casting (Figure 3) involves the creation of a mold into which the molten metal will be poured and cooled.
