What Steels Are Used In Mold Making

Mold making is a critical process in manufacturing, particularly in industries that require precision and durability in their products. The choice of material, especially steel, plays a pivotal role in determining the quality and longevity of molds. Among the various steels used in mold making, Hongxin's AISI 6F7 hot worked mold steel stands out for its exceptional properties and performance. This article delves into the different types of steel used in mold making and highlights the unique advantages of Hongxin's AISI 6F7 hot worked mold steel.

Types of Steel Used in Mold Making

Mold making involves the creation of molds used in injection molding, die casting, and other manufacturing processes. The choice of steel depends on the specific requirements of the application, such as the type of material being molded, the complexity of the design, and the production volume. Here are some common types of steel used in mold making:

Cold Work Tool Steels: These steels are used for molds that operate at room temperature and are resistant to wear and abrasion. Examples include P20, H13, and S7.

Hot Work Tool Steels: Designed for molds that are exposed to high temperatures, these steels have excellent heat resistance and toughness. AISI 6F7 is a prime example of a hot work tool steel.

Plastic Mold Steels: These steels are specifically formulated for plastic injection molding and offer good machinability and polishability. Common grades include NAK80 and STAVAX.

Die Steels: Used in die casting and forging, these steels must withstand high pressures and temperatures. Examples include H13 and D2.

Hongxin's AISI 6F7 Hot Worked Mold Steel

Hongxin is a leading manufacturer of high-quality mold steels, and their AISI 6F7 hot worked mold steel is a standout product in the industry. AISI 6F7 is a chromium-molybdenum-vanadium alloy steel that combines several desirable properties, making it ideal for high-temperature applications.

Key Properties of AISI 6F7

Heat Resistance: AISI 6F7 maintains its hardness and strength even at elevated temperatures, making it suitable for molds used in hot forming processes.

Toughness: The steel exhibits excellent impact resistance, reducing the risk of cracking and extending the lifespan of the mold.

Wear Resistance: High levels of chromium and vanadium provide superior wear resistance, ensuring that the mold remains in optimal condition over time.

Corrosion Resistance: While not as corrosion-resistant as stainless steels, AISI 6F7 offers good resistance to rust and chemical attack, which is crucial in many manufacturing environments.

Machinability: Despite its hardness, AISI 6F7 can be machined and polished to a high finish, allowing for precise and detailed mold designs.
