Factors Affecting the Dimensions of Stainless Steel Castings
Author: SAIVS Date Published: Oct 21,2024
Investment Casting is a method that produces complex-shaped stainless steel castings with precise dimensional tolerances and excellent surface quality. This technique often eliminates the need for further machining, which can be cost-prohibitive or impractical with other methods. While the dimensional accuracy of stainless steel castings from investment casting is generally high, various factors can lead to inaccuracies.
Types of Dimensional Inaccuracies
Systematic Inaccuracies: These arise from poor handling, incorrect assembly of wax models, or deviations from prescribed technology. Careful adherence to procedures can often eliminate them.
Random Inaccuracies: These are harder to rectify and can stem from material and design variations, particularly in areas with non-uniform wall thickness.
Key Factors Influencing Dimensional Accuracy
Volume Expansion/Contraction: The materials used—wax, shell, and casting—significantly impact the final dimensions and the precision of the wax model molds.
Deformation of Wax Models: Cooling and storage conditions can affect the wax model's shape.
Shell Deformation: The composition of the shell, along with the methods used for wax model smelting and firing, influences its integrity.
Casting Deformation: Factors such as the casting shape, gating system, and temperatures during the pouring process can lead to dimensional changes.
Deformation is often unavoidable for specialized designs, such as long, thin brackets despite rigorous procedural adherence. For example, a customer, Joey from Australia, submitted a long bracket design. After evaluation, our engineers determined that straightening would be necessary post-casting, as the design inherently predisposed it to deformation.
In conclusion, while many foundries in China offer stainless steel casting services, only experienced companies like saivs can assure consistent quality and accuracy. If you’re seeking reliable stainless Steel Casting solutions in China, please reach out to us!
