The non sparking safety tools development history 

Non sparking hand tools development:Cast Blank/steel mold casting process/precision casting/punch forging

First generation : Cast Blank

  Draw lessons from Denmark Casting process,mould blank producing process,and sales on market, and filled the national gap.

    Cast type products have pores, voids, loose casting, rough and irregular surface, easy to bend, easy to deform, easy to break, and short service life.

Second generation product: steel mold casting process

    The surface of steel mold casting products is rapidly refined, which solves the surface voids and improves the quality of some products, but it is still a steel mold casting product. In a product transition stage.

The third generation product : precision casting process

    Precision casting products, smooth surface, uniform density, no pores and no voids, improve the accuracy of the product, enhance the mechanical properties of the alloy, and improve the market competitiveness.

Fourth generation product: punch forging manufacturing process

    The company successfully created the copper alloy punch forging process, changed the production process of non-sparking tools, and rolled by different tonnage friction presses according to the tool size.

    Advantages: high density, good toughness, high torque,smooth surface, clear handwriting, not easy to bend and break, uniform hardness, long use life.
