In modern sheet metal processing, press brake tooling is a key component that determines bending quality and production efficiency. The choice of press brake tooling material not only affects the durability of the mold, but is also directly related to processing accuracy and product quality.
With the diversification of market demand and the continuous development of technology, different press brake tooling materials have emerged, each with unique performance characteristics. This article will explore in depth the types, characteristics and applicable scenarios of common press brake tooling materials to help you find the best choice and improve production efficiency.
Introduction of press brake tooling material
There are many types of press brake tooling materials. According to their characteristics and uses, they can be divided into steel materials, alloy materials and polymer materials.
Among them, steel dominates, mainly including carbon tool steel, low alloy tool steel, high carbon high chromium tool steel, high carbon medium chromium tool steel, high speed steel (HSS), 42CrMo high strength alloy steel, carbide, and Steel and carbide composite materials, etc. Below is a detailed introduction to each material.
Carbon tool steel
Carbon tool steel is an economical mold material, and common types are T8A and T10A. Due to its high carbon content, hardness up to 60-65HRC, simple composition and low cost, it is widely used in light-load and general hand tool manufacturing.
This kind of steel has good mechanical properties, but its hardenability and red hardness are poor, it is prone to significant deformation during heat treatment, and its load-bearing capacity is low. Therefore, carbon tool steel is often suitable for lightweight bending applications with limited budgets.
Low-alloy tool steel
Low-alloy tool steel contains elements such as molybdenum, vanadium, manganese, and silicon, which significantly improve the hardness, toughness, and wear resistance of the material. Common types include CrWMn, 9Mn2V, 7CrSiMnMoV and 6CrNiSiMnMoV.
This type of steel has better toughness and wear resistance, longer life, and is suitable for bending harder materials such as stainless steel. Due to its stable performance, low-alloy tool steel is suitable for various medium- and heavy-duty bending processing scenarios.
High carbon and high chromium tool
High carbon and high chromium tool steel is a material with excellent wear resistance. Common types include Cr12, Cr12MoV and Cr12MoV1. This steel has high carbon and chromium content, has excellent strength, wear resistance and hardenability, and performs well in high-load machining.
However, due to obvious carbide segregation, its unevenness needs to be reduced through axial upsetting and radial drawing processes. High carbon and high chromium tool steel is suitable for high-precision and high-load mold manufacturing, such as the bending processing of automobile parts.
High carbon medium chromium tool
High carbon medium chromium tool steel is an improved material, common types include Cr4W2MoV, Cr6W and Cr5MoV. Compared with high carbon and high chromium tool steel, this type of steel has lower chromium content, more uniform carbide distribution, small heat treatment deformation, good hardenability, and high dimensional stability.
High carbon, medium chromium tool steel is suitable for applications that require high heat treatment deformation, such as aerospace and precision manufacturing.
High-speed steel (HSS)
High-speed steel (HSS) is a mold material with excellent performance. Common types include W18Cr4V, W6Mo5Cr4V2, etc. High-speed steel is known for its high strength, wear resistance and compressive strength, and it maintains its hardness (62-67 HRC) even at high temperatures.
In addition, it has a very high load-bearing capacity and is suitable for bending operations that are subject to significant thermal stress over long periods of time. High speed steel is widely used in high thermal stress processing scenarios in the aerospace and automotive industries.
42CrMo high-strength alloy steel
42CrMo high-strength alloy steel is a high-quality alloy steel that has been quenched and tempered and has high strength and toughness. It is unique in its ability to operate in cryogenic environments (-500°C) while providing exceptional durability and impact resistance.
This steel is commonly used in the heavy machinery and construction industries and is ideal for heavy-duty bending operations where durability is required.
Carbide
Carbide is composed of tungsten carbide and cobalt and is known for its extremely high hardness and wear resistance. Despite its higher cost, its long life and high efficiency make it the first choice for high-frequency, high-precision bending operations.
Carbide is particularly suitable for long-term continuous production and high-end precision machining, such as bending operations of components in the electronics industry.
Steel and carbide composite material
Steel and carbide composite material is a new material that combines the characteristics of cemented carbide and steel. It combines the high hardness and wear resistance of carbide with the toughness and processability of steel, achieving a balance between wear resistance and processability. The material is suitable for high-precision bending operations where versatility is required.
By understanding the above materials, companies can choose the most suitable mold materials according to specific needs, thereby achieving the best balance between processing efficiency and cost.
