随着电缆行业发展需要、电缆产品种类的多样化以及客户对电缆产品的特殊需求型，电缆类模具的种类及要求也逐渐增加。目前，电缆行业涉及到的模具较多的有：拉丝、绞合模具；紧压成型模具、成缆模具；挤出模具等。下面我们对电缆行业常用模具进行大概梳理，并针对我们工作接触较多的模具进行解析。
With the development needs of the cable industry, the diversification of cable products and the special needs of customers for cable products, the types and requirements of cable molds are also gradually increasing. At present, there are many molds involved in the cable industry: wire drawing and stranding molds; Compression molding die and cable forming die; Extrusion die, etc. Next, we will roughly sort out the common molds in the cable industry and analyze the molds we have more work contact with.
二、拉丝、绞合模具的种类、性能及应用
2、 Types, properties and applications of wire drawing and stranding dies
2.1 此类模具一般称为线模，可分圆模和型模，常用线模材料有钻石模、硬质合金模、聚晶模等。
2.1 this kind of mold is generally called wire mold, which can be divided into circular mold and mold. The commonly used wire mold materials include diamond mold, cemented carbide mold, polycrystalline mold, etc.
a 钻石模：钻石模也称金刚石，具有最高的硬度，耐磨，但价格较贵。在拉丝中，一般用在拉小规格单丝，如Φ0.40mm 及以下规格。
A diamond mold: Diamond mold, also known as diamond, has the highest hardness and wear resistance, but the price is more expensive. In wire drawing, it is generally used to pull small-sized monofilament, such as Φ 0.40mm and below.
b 硬质合金模：在拉伸生产中，过去使用的钨钢模全为硬质合金模所代替的。因为硬质合金模拉伸模与钢模相比具有：耐磨性较好， 抛光盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门性好、对被加工金属的粘附性小，摩擦系数小，导热系数高和具有很高的耐腐蚀性。
B cemented carbide die: in the drawing production, the tungsten steel die used in the past was replaced by cemented carbide die. Because the drawing die of cemented carbide die has better wear resistance, good polishing, low adhesion to the processed metal, low friction coefficient, high thermal conductivity and high corrosion resistance compared with the steel die.
