The Premier Choice for High-Precision Components: Shell Molding Casting
Kunyongda adopts advanced Shell Molding Casting technology. By utilizing high-temperature metal molds and thermosetting resin sand to form precision shell molds, we achieve stable dimensional accuracy and excellent surface quality, which is widely applied in the manufacturing of high-requirement parts.
Shell molding is a precision casting process that uses resin-coated sand to cure on a heated metal pattern, forming a thin, shell-like mold. Compared to traditional sand casting, shell molding provides a denser mold structure and excellent permeability, significantly reducing the risk of porosity and sand inclusions in the castings.
Leveraging extensive experience in shell molding, Kunyongda brings the following significant advantages to our customers:
The high rigidity and low deformation rate of the resin shell mold allow casting dimensional tolerances to be controlled within a very tight range (e.g., to grades), ensuring high consistency in batch production.
The smooth and refined surface of the castings significantly reduces or even eliminates the need for subsequent rough machining, effectively lowering overall manufacturing costs.
Excellent metal fluidity makes it easy to handle high-difficulty parts with complex geometric shapes, deep holes, or thin-walled designs.
The shell mold preparation is fast and easy to automate, making it highly suitable for medium-to-large batch production of high-end products with strict quality requirements.
The stability of shell molding casting makes it the preferred choice for many demanding industries. Common applications include:
Precision valve bodies and pump housings that withstand high pressure.
Engine components, transmission cases, and high-strength structural parts.
High-precision gears and compressor parts.
