Lost Wax Process Heat Treat Baskets

Lost Wax Process Heat Treat Baskets are essential high temperature treatment carriers in the precision investment casting (lost wax casting) industry. They are designed to cope with the harsh environment of high temperature heat treatment furnaces (such as solution treatment, aging hardening, hot isostatic pressing, etc.), and are used to safely and efficiently hold and transport complex and precise wax castings. These baskets are made of specially designed high temperature alloy materials to ensure structural integrity and creep resistance at temperatures, effectively preventing deformation, adhesion or surface damage of castings at high temperatures. Its exquisite grid structure not only allows the uniform circulation of heat treatment atmosphere (such as inert gas or vacuum) and quenching medium (oil, water or polymer solution), ensuring consistent heat treatment effect and ideal cooling rate for the entire loading batch, but also minimizes the risk of physical collision of castings during handling and processing. It is a core tool to ensure the quality and yield of high-value, high-precision castings (such as aerospace turbine blades, medical device components, complex artworks, etc.) in key heat treatment links.

When designing Lost Wax Process Heat Treat Baskets, engineers took into account the unique geometric complexity, surface finish requirements, and batch processing efficiency needs of investment castings. The construction of the baskets usually includes adjustable internal compartments, customized cavity support structures, or sophisticated casting positioning devices to meet the stable loading requirements of castings of different shapes and sizes to prevent them from shifting or contacting each other during high-temperature cycles. Excellent resistance to high-temperature oxidation and carburization/decarburization is the key to its material selection, ensuring that the baskets themselves will not become a source of contamination or premature failure under long-term use. In addition, ergonomic designs (such as sturdy lifting ears and reasonable weight distribution) facilitate safe use of forklifts or overhead cranes for automated handling, significantly improving the efficiency of the production process and reducing the labor intensity of operators. Therefore, these special baskets are not just simple containers, but also a key link in the precision casting value chain that connects casting and final performance standards, providing reliable guarantees for the production of top-quality investment castings with strict mechanical properties and dimensional tolerances.
