Custom Steel Lost Wax Casting Bracket

Product Introduction

This is a steel lost-wax casting bracket,  whether it's bearing heavy loads, withstanding extreme temperatures, or fitting into tight, specialized spaces, custom steel lost wax casting brackets deliver precision, strength, and adaptability, making them indispensable for advanced engineering applications.

Material and process

It's made from #45 steel by lost wax casting, or water glass casting. It's light and weighs 35g, there are left and right part to use cooperatively. The custom nature ensures that every aspect, from intricate structural designs to exacting dimensional tolerances, aligns with unique project needs.

Here is the bracket drawing:

Then we conducted in - depth analysis and, after careful consideration, confirmed that lost wax casting was the optimal manufacturing process for fabricating the bracket. This decision was based on multiple factors, such as the need for high precision in the bracket's complex geometry, the requirement to achieve intricate details, and the desire for a cost  effective solution.

First,  the fabrication of wax patterns and the assembly of the wax tree are essential initial steps. The wax patterns must be crafted with extreme precision, as they serve as the exact replica of the final steel bracket.

Once the individual wax patterns are completed, they are carefully attached to a central wax sprue to form a wax tree.

Then, the wax tree undergoes a meticulous investment casting preparation process. It is carefully dipped into a precisely formulated water glass slurry, which acts as a bonding agent. Immediately after, it is coated with refractory sand, the particles of which adhere to the slurry  covered wax tree, building up a protective and mold forming layer.

The coated wax tree is then transferred to a specifically designed drying room. In this controlled environment space, with regulated temperature and humidity, the water in the slurry evaporates, and the layer hardens. This dipping  coating  drying cycle is repeated 5 to 8 times.

Once the desired number of layers is achieved and the shell is sufficiently robust, it is placed into a furnace. Inside the furnace, the shell is baked at a high temperature. This baking process serves multiple purposes: it fully dries the shell, removes any remaining moisture, and also melts and removes the wax tree inside, leaving behind a precise, hollow mold cavity.

Then the molten steel heated to its liquid state at extremely high temperatures, is carefully poured into the empty shell mold. The molten steel fills the cavity, taking on the exact shape of the original wax tree. Then, we wait for the molten steel to cool down naturally within the shell. As it cools, the steel solidifies, forming the final custom steel lost wax casting bracket.

The hole in the middle, 15H7, is very important.

After processing, a gauge is needed for inspection.
