Abstract: A silicon steel bars checking device includes a top board, a bottom board, a block unit and multiple bolts. A room is defined between the top board, the bottom board and the block unit. The silicon steel bars are inserted into the room and positioned between the top board, the bottom board and the block unit, and checked their specification. The silicon steel bars are removed from the device without any damage.

Abstract: The present invention discloses a composite molded casing, which comprises a casing body having a mold line and a decorative layer coated on the surface of the casing body to cover the mold line. The present invention exempts the composite molded casing from complicated secondary machining processes (such as processes of grinding and polishing) and thus indirectly reduces the fabrication cost of molds and promotes the yield of products. Further, the present invention uses an IMF technology to fabricate the decorative layer, not only completely covering the mold line but also overcoming the problem of color difference likely to occur in the conventional injection-molded plastic products. Therefore, the present invention can exempt the composite molded casing from complicated post-fabrication processes, such as processes of paint spraying, printing, electroplating, photoelectric engraving, etc.
