TMolded Channel PlatformFeatures:

①TThe work surface of the mold platform must not have defects such as sand holes, gas holes, cracks, shrinkage cavities, scratches, dents, rust spots, etc., which significantly affect appearance and usage.

②TThe surface of the mold platform should be coated with molding sand and be smooth, with a firm paint finish.

③Precision Grade:0Grade-3GradeTOn the work surface of the mold channel platform, diameter less than15mmThe sand holes allow for blocking with the same material, but the hardness should be less than that of the surrounding material. The number of sand holes that need to be blocked on the working surface should not exceed4Pieces, and the spacing between sand holes should not be less than80mm。

④TThe mold slot platform should be adopted   Manufactured from fine gray cast iron or alloys, the working surface hardness should reach170-220HB。

⑤TThe working surface of the profiled platform typically should be processed by scraping. For those using scraping processing,3GradeTType slot platform work surface, with a surface roughnessRaThe permissible value is5um。

⑥The scraping process should be followed by a color match inspection. The ratio of contact point areas displayed after the match grinding is shown in the table.3Regulation: Or as specified.25mm×25mmThe number of contact points for square area is listed in the table.3Regulations, and any25mm×25mmThe number of contact points should not exceed5Dot.
