What are casting tolerances?
General casting tolerances mean that after casting various metal castings, the measured values of the parts must be regarded as acceptable limit values. Therefore, the precise dimensions of castings require more accurate and strict tolerances.
The main content of casting tolerances
Generally, we divide casting tolerances into two parts: linear tolerance and shape tolerance
Linear Tolerance
Refers to the distance between two points, such as diameter, radius, width, depth, height, center distance, etc. The general standard uses millimeters (mm) as the basic unit of size. Generally speaking, the dimension unit is millimeter by default. Best Casting Company can meet your investment casting needs according to your actual situation.

geometric tolerance
Geometric tolerances include shape tolerances and position tolerances. Any part is composed of points, lines and surfaces. These points, lines, and areas are called elements. The actual elements of the processed parts always have errors relative to the ideal elements, including shape errors and position errors. Such errors affect the functions of mechanical products, and the corresponding tolerances should be specified in the design, and marked on the drawings according to the specified standard symbols.
