Lostwax Diecasting

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.

-----------------------------------------

Feature

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.
