The development history of OUYANG non-sparking hand tools

Here we want to write some words for OUYANG Non-Sparking Hand Tools,thank you for your reviewing.

First generation :

Cast Blank

Draw lessons from Denmark Casting process,mold 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 die 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.
