我国硬质合金模具根据用途可分为四类：第一类为硬质合金拉丝模具，这类模具占硬质合金模具的绝大部分。我国目前拉丝模的主要牌号YG８、YG６、YG３，其次是YG１５、YG６X、YG３X，近几年来主要硬质合金生产厂家也研制一些新牌号，如用于高速拉丝的新牌号YL，还有从国外引进的 China’s carbide mold can be divided into four categories according to use: The first category for the hard alloy drawing dies, molds accounted for the vast majority of carbide mold. China’s current drawing die main brands YG8, YG6, YG3, followed by YG15, YG6X, YG3X, in recent years the major manufacturers of cemented carbide has also developed some new grades, such as for the new high-speed wire drawing YL, as well as from abroad Introduced
