Five kinds of steel are commonly used in plastic molds

Plastic die steel is the key material for manufacturing plastic die, and its performance, quality and durability directly affect the service life and product quality of plastic die. In the choice of plastic die steel, there are five common steel worthy of our focus. This article will give you a detailed analysis of these five steels to help you make better choices in practical applications.

First, pre-hardened die steel

Pre-hardening die steel is to increase the hardness and wear resistance of die steel by increasing a certain hardness treatment in the production process. The representative of this type of die steel is gd steel, whose composition mainly includes C, Cr, Ni, Si, Mn, Mo, V and other elements. gd steel has high strength, high toughness and wear resistance, which is suitable for the manufacture of cold stamping dies that are easy to collapse and break. Due to its high service life, gd steel has become a popular choice in the field of cold stamping dies.

Two, high strength die steel

High strength die steel performs well in terms of strength and hardness and can withstand large shocks and pressures. The representative of this type of die steel is high-speed steel, and its main components are C, Cr, Mo, V, W and other elements. High speed steel has high red hardness and wear resistance, which is suitable for manufacturing high strength molds such as high-speed cutting and deep hole drilling. In the manufacturing of plastic molds, high-speed steel is often used to manufacture the cutting edge of the mold, cutting parts and other high-strength, high-wear parts.

Third, high toughness die steel

High toughness die steel has a good balance between strength and toughness, which can effectively avoid problems such as fracture in the production process of the die. The representative of this type of die steel is alloy tool steel, whose main components include C, Cr, Ni, Si, Mn, Mo, V and other elements. Alloy tool steel has good toughness and wear resistance, which is suitable for manufacturing complex and large plastic molds. In practical applications, alloy tool steel is often used to manufacture plastic molds in automotive, home appliances and other fields.

Four, stainless steel die steel

Stainless steel die steel has good corrosion resistance and is suitable for manufacturing plastic molds with high corrosion resistance requirements. This type of die steel is represented by martensitic stainless steel, its main components are C, Cr, Ni, Si, Mn, Mo, V and other elements. Martensitic stainless steel has good corrosion resistance and wear resistance, and is often used in plastic mold manufacturing to make mold cavities, guide posts and other parts.

Five, powder high speed steel

Powder high speed steel is a new type of high performance die steel with high strength, high toughness and wear resistance. The representative of this type of die steel is powder high-speed steel, whose main components are C, Cr, Mo, V, W and other elements. Powder high speed steel has high red hardness and wear resistance, which is suitable for manufacturing high strength molds such as high speed cutting and deep hole drilling. In the manufacture of plastic molds, powder high-speed steel is often used to manufacture the cutting edge of the mold, cutting parts and other high-strength, high-wear parts.

In SUMMARY:

When choosing plastic die steel, it is necessary to consider it comprehensively according to the actual production needs and the characteristics of the mold. Pre-hardened die steel, high-strength die steel, high-toughness die steel, stainless steel die steel and powder high-speed steel these five steels have their own characteristics, respectively, suitable for different types of plastic mold manufacturing. Through in-depth understanding and mastering the performance characteristics of these steels, we can better choose the right steel for plastic mold manufacturing, improve the service life of the mold and product quality.
