| Brief introduction of stamping die in Dongguan The materials for making Dongguan stamping die include steel, cemented carbide, steel bonded carbide, zinc based alloy, low melting point alloy, aluminum bronze, polymer material and so on. At present, most of the materials for stamping die are mainly made of steel. The common types of die working parts are carbon tool steel, low alloy tool steel, high carbon or medium chromium or medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel, hard alloy, steel cemented carbide and so on. Basic classification A. carbon tool steel The carbon tool steels used in stamping dies in Dongguan are T8A and T10A. The advantages are good workability and low price. But the hardenability and red hardness are poor, the heat treatment deformation is large, and the bearing capacity is low. B. low alloy tool steel Low alloy tool steel is based on carbon tool steel with a suitable amount of alloying elements. Compared with carbon tool steel, the quenching deformation and cracking tendency are reduced, and the hardenability and wear resistance of the steel are improved. The low alloy steels used for making moulds are CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD), etc. C. high carbon and high chromium tool steel The common Dongguan punching dies have Cr12 and Cr12MoV, Cr12Mo1V1 (code D2) and SKD11. They have good hardenability, hardenability and wear resistance, and the heat treatment deformation is very small. It is a high wear resistant micro deformation die steel, and the bearing capacity is second to high speed steel. However, the segregation of carbide is serious, so repeated upsetting and drawing (axial upsetting and radial pulling) should be repeated to reduce the inhomogeneity of carbides and improve the service performance. |
