Casting tolerances depend on the materials used in the production and the casting method. According to international standardization

Organization (ISO) standard for general metal alloy castings, ISO 8062 MCL cast iron shall be cast with sand casting mould as an example。 Must meet casting tolerance (CT) of 8

Level 12. The molding sand casting capacity of our factory can control the casting conformity

Casting (CT8) to tolerance standard (CT9) grade. Suitable for all mechanical production of fixed

Parts and rotating parts.

More precise tolerances are available in specific situations

The detailed table of CT8 and CT9 is as follows:
