Zeren Investment Casting Tolerance Table
Introduction to Our Investment Casting Tolerance Table
At Foshan Zeren, we guarantee high-precision investment castings by adhering to strict quality standards, including the German VDG P690 guidelines. 
Our Investment Casting Tolerance Table provides clear reference values for length, width, height, and hole positioning, helping clients optimize designs and reduce post-cast modifications. These standardized tolerances ensure consistency for complex geometries in aerospace, automotive, marine, and medical industries. 
For tighter tolerances, our CNC machining services deliver additional precision. The table serves as a key reference for design and quality control, ensuring smooth production. Review our tolerance chart to align your requirements with our capabilities for optimal results.
