Manufacturers Still Using Investment Casting Process for Producing Most Intricate Casting Shapes

Investment casting is still the most preferable casting process for manufacturers. They use special wax patterns, which are coated with a refractory ceramic material. Once the coated layer is hardened, its internal geometry takes the casting shape. Later, investment casting manufacturers India melt the wax to get the cavity to pour molten metal. They leave the molten metal for solidification within a ceramic mold and after that metal casting is broken out.

At times, this technique is recognized by the name of lost wax process and it was first introduced over 5500 years ago in China and Egypt. Some of the parts fabricated in industry using this process include gears, dental fixtures, cams, ratchets, turbine, machinery components, jewelry, and other complex geometry parts.

Major properties and considerations for investment casting manufacturing foundries:

  • The process allows engineers to shape complex parts along with good surface finish.
  • Engineers can intend and get thinner sections with this process.
  • Carbon Steel Castings Manufacturers can achieve high dimensional tolerance with investment casting method.
  • Initially, any type of metal can be used and cast with this process.
  • Manufacturers claim that investment casting is a bit complicated process and expensive than other processes. This claim is real and true.

Can manufacturing foundries replace the lost wax process with any other casting process?


Though technology has provided many other options and processes to cast metal shapes yet investment casting is recovering lost ground. Manufacturers have understood the fact that what investment casting can provide them can’t be replaced. They can’t have such super finished Manganese Steel Casting ranges using other casting processes and thus, investment casting process is once again leading the race.

There is no such casting process that can replace lost wax or investment casting method. It offers high production rate, mainly for small or extremely complex parts, and highly good surface finish with little machining requirement.

How to get reliable suppliers of castings across the world?

Google is a giant platform where you can get a list of casting suppliers. You must know to differentiate between the faux and reliable casting supplier to avail quality casting products. Sometimes business directories do wonder and let you know the best deals providers. You can use either online or yellow pages directories to fetch out some leading investment casting manufacturers’ name. When you found them-don’t forget to compare their products, quality service, and experience.
