In industry, we find a wide range of techniques for the creation of complex parts and components. One of these techniques is the creation of wax molds, which has its roots in ancient times. Although it may be hard to believe, the Indians, Sumerians, Chinese and Incas, independently and in parallel, were already using beeswax to make molds that were then filled with long-lasting and resistant materials, such as gold and other metals.

The current technique consists of creating a wax mold and covering it with a more resistant material, such as ceramic, and then melting the wax to obtain a mold that can withstand the heat of the molten metal.

Casting wax types

There are many waxes that can be used for this purpose. Nowadays, mixtures of natural and synthetic waxes are often used, resulting in a highly malleable material that enables the creation of high-precision molds that give excellent finishes.

The choice of the appropriate wax depends on the flow properties, the need to recycle the wax or not, the application requirements and the desired surface finish, among other factors. Among our products, we offer two types of casting wax.

These types of wax contain fillers that give it specific properties to ensure strength, stability, low expansion at high temperatures and minimal shrinkage. On the other hand, these types of wax can be more difficult to remove from the mold.

Non-filled pattern wax

This type of wax does not contain filler materials and gives great mechanical and thermal performance. It is generally preferable when creating molds with complex shapes or patterns. It has an excellent flow and gives surfaces with a formidable finish. Last but not least, it is perfectly reusable and recyclable.
