Why is Lost Wax Casting so Famous?

Investment casting is a process in which pattern of parts are molded, the wax pattern of part design and coated with refractory ceramic substance. After the material becomes tough internal geometry takes the form of casting. This complete process is also known as Lost Wax Casting. The product should be manufactured using superior quality raw materials as per international standards and specification, to produce high quality casting equipment. If the primary material is lower in quality then final casting product may be unwanted and faulty for longer period.

The casting design and specification may differ as per industrial requirements and usage of the customers. With the help of accurate and precise investment casting various parts like aerospace parts, power plant boiler parts, non-ferrous and ferrous parts, marine parts, industrial valves & pumps, firefighting equipment, jewelry, turbine blades etc. are manufactured. 

In the investment casting generally two procedure are followed, Silica Sol Process and Water Glass Process. Silica sol process mainly used for manufacture smaller design parts while Water glass process used for larger design parts like grey iron, alloy steel, carbon steel, and ductile iron. Apart from this lost wax casting is highly popular process to manufacture investment casting parts.

Advantages of Lost Wax Casting 

1. This process provides higher design flexibility, means complex shapes casting parts can be possible.
2. It provides greater details, close tolerances and excellent outward finishing.
3. It’ll reduce material cost and produce near net cast products.
4. It eliminates expensive and costly fabrications.
5. With the help of lost wax any metal can be cast.

Disadvantages of Lost Wax Casting

1. Labor cost is expensive
2. The process of manufacturing is lengthy that’s why it’s time consuming process
3. At one point casting size can’t exceed
4. Rarely or occasionally found faults

Applications
