In the mechanical industry casting is a process to develop or build different parts which has various shape and size along with perfect finishing. The products which are built through this process are known as casting products. In the casting process mold is created as per desired shape and pattern in which metal is poured and after the cooling phase it become exact or desired casting parts.
Casting process is a traditional process it has been known from thousands of years, and most popular method to develop small and accurate casting parts. There are mainly three procedures to develop casting parts such as Expendable Mold, Non-Expendable (Permanent) Mold, and Other. In these procedures mainly water & clay mold, Investment casting and die casting are famous sub process.
Investment casting is also known as lost wax casting, it’s one of the oldest metals forming technique. This process is ensure and guaranteed to produce superior and high quality components. In the investment casting foundry excellent and precise casting components are building, sometimes complex or critical design products also manufactured.
In the non-expandable casting mainly non-ferrous metals are used to produce casting parts, set up process of mold is time consuming but after that it produce around 10-50 pieces/hr-mold. These products are high in tensile strength compare to other casting. Generally iron, magnesium, aluminum alloys and nickel alloy casting are used to produce durable components.
Sand casting is one of the easiest and popular types of casting, it allows small groups to produce numerous number of casting such as 5-25 pieces/hr-mold. In this type of process most of the metals are applicable as per sand is used.
In the continuous casting production remain continuous with the help of reused and refinement mold. The product which are manufactures are premium in quality and strength, metals like steel, aluminum and copper are generally used to produce huge range of casting parts. This type of huge casting production is offered by Energy Technocast Pvt. Ltd. with an international standard and quality at the lowest price.
Last words, Different casting manufacturer uses various casting technique to produce high quality and durable casting components. Some of the other detailed casting types are available, hope present casting types are useful.
Waiting for your words and ideas in below comments.

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
- This process provides higher design flexibility, means complex shapes casting parts can be possible.
- It provides greater details, close tolerances and excellent outward finishing.
- It’ll reduce material cost and produce near net cast products.
- It eliminates expensive and costly fabrications.
- With the help of lost wax any metal can be cast.
Disadvantages of Lost Wax Casting
- Labor cost is expensive
- The process of manufacturing is lengthy that’s why it’s time consuming process
- At one point casting size can’t exceed
- Rarely or occasionally found faults
- Medical field
- Automobile industry
- Industrial Gas Turbine
- Industrial Pumps & Valves
- Industrial boiler parts
- Ferrous & Non-Ferrous parts
- Firefighting parts
Last Words, Lost wax casting is highly popular and affordable manufacturing process, for better quality and finishing always follow this process. Looking forward to your views and ideas in comments.
