Precision casting of heat-resistant steel heat treatment trays | Customized furnace tooling trays

Heat-resistant steel heat treatment trays are mainly designed for custom-made applications based on drawings, serving as load-bearing components for heat treatment furnaces, industrial furnaces, and high-temperature tooling. Product pricing cannot be determined solely by shape or weight; it also requires a comprehensive evaluation considering material standards, batch quantity, critical dimensions, tolerances, surface treatment, and the actual operating environment.

Structural and process evaluation of heat-resistant steel heat treatment trays

These types of parts typically require close attention to the mesh stiffeners, load-bearing units, and large-area thin-walled structures. Silica sol is used.Investment CastingDuring the drawing review stage, the wall thickness transition, fillets, parting method, casting shrinkage compensation and machining allowance will be confirmed to deal with deformation, shrinkage cavities, air holes and subsequent clamping risks as much as possible in advance.

If the parts involve pressure resistance, corrosion resistance, food contact, high temperature, or continuous stress, please specify the medium, temperature, pressure, load, and applicable standards when requesting a quote. Common designations such as 304, 316, and 316L are only preliminary guidelines; formal production should adhere to the grade, chemical composition, and acceptance requirements specified in the drawings.

Compatible CNC post-processing

After the casting blank is cleaned, the positioning surfaces, installation positions, and furnace loading dimensions can be arranged according to the drawings. For assemblies, the datum, key tolerances, surface roughness, and fit relationships should be marked in advance. For projects that require batch delivery, mass production can begin after the first piece is confirmed to reduce dimensional discrepancies.

Inspection and Delivery Key Points

• Material:Confirm the furnace batch and material requirements according to the agreed grade, and communicate the spectrum or material report if necessary.
• size:The key areas to check are the hole positions, end faces, threads, mating surfaces, and critical dimensions marked on the drawings.
• Appearance:Check for cracks, missing material, obvious pinholes, deformation, and cleaning condition.
• Specialized testing:For pressure-bearing, sealing, or critical load-bearing components, non-destructive testing and performance verification can be negotiated on a project-by-project basis.

What information should be provided in the inquiry?

We recommend providing PDF drawings, CAD or STEP models, material grade, purchase quantity, key tolerances, surface treatment, and expected delivery date. If the information is incomplete, you can also send photos of the actual product, its intended use, and key dimensions for process engineers to determine suitability.Investment Casting。
