What is Lost wax diecasting?


Lost-wax casting is a process for creating objects, from simple to complex, in a variety of metals (such as gold, silver, brass, or bronze) by casting an original model or pattern.

It is one of the oldest known metal-forming techniques dating back 6,000 years, but it is still widely used for producing jewelry, dentistry, and art. Its industrial form, investment casting, is a common way to create precision metal parts in engineering and manufacturing.

While traditionally associated with artisanal handcraft, creators can now transform the lost-wax casting process with digital design and 3D printing to simplify the workflow, save time, lower costs, and reshape the process for  the 21st century.



The mold cost is low, and the initial cost can be reduced. Therefore, it is a manufacturing method that is easy to achieve cost benefits even for small lot products.

2. The mold can be used semi-permanently. No need to update the mold.

3. It is possible to manufacture complicated 3D shapes relatively cheaply.

4. Abundant materials (4 steel types: iron, stainless steel, copper, and aluminum)

Manufacturing Procress

01 Wax molding : Create wax patterns by injecting wax into mold.


02. Ceramic coating : Coat about 4 to 6 layers of ceramic liquid and powder on the wax tree.

03. Dewaxing : Remove wax by high-temperature steam pressure

 4. Mold firing : Burn out wax completely, and sinter ceramic mold.

 05. Casting : Pour molten metal into the mold

 06. Cutting : Remove the mold and cut products from the tree.

07. Heat Treatment : Realize stable metal structures by heat treatment.

 08. Inspection : Inspect the product based on various strict quality standards.
