  • Mold making inspection (3)

    Carbide inhomogeneity Cr12 type Leysite steel contains a large amount of eutectic carbides in the structure. Carbide inhomogeneity has a very important influence on the performance of use, so the distribution of carbides must be strictly controlled. All in all, because the production objects of the ... read more

  • General design rules for vacuum forming dies. (2)

    Geometric shape design, design, often have to consider the dimensional stability and surface quality. For example, product design and dimensional stability require the use of a female mold (female mold), but the surface requires a higher gloss product, but requires the use of a male mold (protrusion... read more
