If you want to create complex objects like metal, silver, or bronze, there is one process that will help you out, and it is the lost-wax casting.

Precision casting or lost wax casting has been widely in use since the oldest times. According to research, it is the oldest-known method of metal-forming with a history of 6000 years and is still most commonly used.

The manufacturing process is pretty simple and versatile and takes place manually or with the help of the latest machinery.

Now, let’s quickly get an idea of how lost wax casting can prepare your desired products?


How to Prepare Casting Products with Lost Wax Casting?

Lost wax casting is also known as the cire-perdue method of metal casting. This process generally involves the preparation of a mold by using wax as a manufacturing material.

Lost wax casting is a very accurate method for the preparation of products because it has an accurate tolerance of 0.005.

Following are the 5 major steps involved in the preparation of lost wax casting:

1- Preparation of a model or mold in the wax.

2- Removing the wax and choosing the metallic alloy

3- Pouring the molten wax into the mold cavity and then cooling the molten metal.

4- solidifying the molten metal and removing the mold.

5- Finally, finish the final product.

Hence, with these steps in hand, you are ready to go to prepare your first casting product.

But, wait.

You might be wondering why companies use this process and why we need it?

To answer this, let’s head over to our main topic of discussion quickly.


Why Do We Use Lost Wax Casting?

For the past few decades, millions of factories and industrial companies have been using this method to prepare cast products. Various daily life applications are taking advantage of this technology. This mainly includes medical, agriculture, and engineering industries.

Here you go with the list that covers all the beneficial points of the lost wax casting process:-


1- Use in Jewellery

The production of ornaments and fine arts is one of the main use cases of lost wax casting. This is the 21st century and you know very well that demand and hype of fashion products are increasing very quickly.

Several fashion industries and designing companies are taking advantage of lost wax casting. Different products involve this casting procedure.

This method involves both manual and latest technologies. Yet, the demand for hand-made jewelry products is more yet it’s a complicated process and takes a long time.

With the help of the latest inventions and machinery, the process of lost wax casting becomes very smooth and easy.

In the modern era, the following technologies involve in the production of casting products:-

  • 3D Printing
  • CAD software tools
  • Prototyping

3D printing is the most widely used among the latest technologies in precision casting. All the digital designs, fashion products, and advanced items involve the technique of 3D printing.

Jewelry manufacturers also use CAD software tools to design different pieces which are difficult to build. But, with the help of CAD software, manufacturers get a lot of benefits in producing precise and accurate geometrical objects.


2- Medical Industry

Do you know lost wax casting has been a crucial part of medical applications for decades?

All medical products, especially dentistry objects, involve the use of lost wax casting. In the field of dentistry, manual molds or models form the traditional die. The master dies then forms a tree-like assembly and is burnt out to give the lost wax workflow.

Enlisted below are some applications of the dentistry industry which involves the use case of lost-wax casting:-

  • Fabricate inlays
  • Onlays
  • Crowns,
  • Ceramic–alloy crowns
  • All-ceramic crowns
  • Partial denture frameworks
  • Other implant restorations

The anatomical features of a patient are not difficult to operate with the help of lost-wax casting. This mainly involves 3D printing and propping of the desired object. This 3-dimensional printing method solves many problems of manual casting. As a result, the manufacturing process becomes pretty easy.

You would be surprised to know that the use of lot-wax casting in the medical industry has made the industry grow in both the analog and digital worlds. The reason is it provides an easy workflow and reduces the risk of manual errors.


3- Use in Manufacturing Industry

For manufacturers who want highly accurate and dimensional metal products, lost-wax casting is the best fit for them.

This method is mainly concerned with production of smaller metal, silver, bronze, gold products that we use in our daily life most commonly. Furthermore, it has a slight difference from investment casting in a way that investment casting produces complicated components more effectively.

On the other hand, the lost wax casting is best for smaller manufacturing products. This includes aerospace, automotive, and several other medical applications.

No wonder, the most important aspect of lost wax casting is the use of 3D printing. So, let’s shortly discuss it below:-


How 3D Printing Plays its Role in Lost Wax Casting?

3D printing has the most vital role in the manufacturing process of casting components. With the use of 3D printing, industries enhance the process of manufacturing, and more versatile components came out as a result.

Historically, the casting method was not that smooth and easy as it involves the use of hand and manually prepared products. However, with the advent of the latest gadgets, different types of machinery have stepped into this process.

This has revolutionized the casting industry and made the process smooth.

CAD software tools, digital design making items, advanced techniques, and of course 3D printing took the investment casting industry to a new level of advancement.



Undoubtedly, with the latest inventions and digital work methods, lost wax casting proved to be a revolution in the industry. The smooth prints, fine designs, and easy processing speed are the unique features of lost wax casting that make the method quick.

Companies and production offices practically enhance this method. Due to this, several casting products involve the use case of lost wax casting that will surely increase in the future.
