TForming Slot PlatformFeatures:

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

②TThe surface of the mold platform should be properly sand-blasted and smooth, with paint that adheres firmly.

③Precision Grade:0Grade-3GradeTOn the mold groove platform work surface, diameter less than15mmThe sand holes can be plugged with the same material, but the hardness should be less than that of the surrounding material. The number of sand holes plugged 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 should typically employ a scraping process. For those utilizing scraping processing,3GradeTType groove platform working surface, with a surface roughnessRaThe permissible value is5um。

⑥The scraping process should be followed by a color matching inspection. The ratio of contact point areas displayed after matching is shown in the table.3Regulation: Or as specified25mm×25mmNumber of contact points for square area is shown in the table.3Regulations, and any25mm×25mmThe number of contact points should not exceed5Dot.
