<h2 data-start="1937" data-end="2065"><br data-start="2091" data-end="2094" /> I&rsquo;m currently evaluating casting methods for producing high-volume metal components and came across the disadvantages of sand casting.</h2>
<h2 data-start="1937" data-end="2065">While I know it&rsquo;s cost-effective and versatile, I&rsquo;m more concerned about the downsides, especially in terms of surface finish and dimensional accuracy.</h2>
<h2 data-start="1937" data-end="2065">Are there modern techniques or post-processing steps that can minimize these limitations? If anyone here has experience balancing cost and quality with sand casting, I&rsquo;d love to hear your advice.</h2>
<h2 data-start="1937" data-end="2065">Is it still a viable choice for high-precision industries in 2025? Any case studies or examples would be great to know.</h2>
<h2 data-start="1937" data-end="2065">Thanks in advance.</h2>

The disadvantages of sand casting usually include rougher surface finishes, lower dimensional precision, and potential defects like porosity. That said, many companies still use it effectively by adding CNC machining or polishing as a secondary process.

For high-precision applications, this combination can give you the cost benefits of sand casting with the finish of more expensive methods. It&rsquo;s also adaptable for different alloys, which adds flexibility. If you need tight tolerances, though, you might want to consider investment casting or die casting.

Your choice depends on the balance between budget, quantity, and desired quality.
