The die board of the automatic rule bender must not be worn or broken, so as not to affect the use of the automatic rule bender. The die board made of good materials can be used for a relatively long time. Therefore, the die board of the automatic rule bender is preferably made of imported high-speed steel.

High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel, and is a widely used material for making the die board of the automatic steel rule die bender.

The die board of the automatic steel rule die bender made of high-speed steel has characteristics of high hardness, high wear resistance and sufficient toughness, so that the die board of the blade bending machine is more durable and does not require frequent adjustment of machine parameters.

This material of the die board is used with a blade bending machine, which greatly improves the production efficiency.
