Some customers think of bending machine tooling as a secondary accessory in sheet metal bending, but the opposite is true. Although bending machines have developed into multi-axis, high-precision machines with self-stabilisation, it is the tooling that actually touches the workpiece during the bending process, and this requires HARSLE tooling that is both high-precision and high-quality. Customers can choose different dies to suit their needs before sectioning, and a wide range of clamps and related accessories are available.



We have the strong technical support team, and if you have any questions, we can give you solutions in 12 hours.



Our machines are designed by our professional team, which guarantees the accuracy and speed of our machines.



HARSLE will offer 3 years warranty for your machine, we can also replace your parts for free during the warranty period.



We have sold tens of thousands of machines, and our customers all over the world are full of praise for our machines.

Development History


Established Nanjing HARSLE Machine Tool Co.,Ltd., engaged in the production, sales and maintenance of sheet metal machinery such as bending machines, shearing machines, punching machines, and hydraulic presses.



Provide customers with a complete set of machines for metal door processing, metal sink processing and other production lines, and have signed cooperation agreements with overseas agents to provide our customers with better services.



The annual sales of both domestic and foreign trade have exceeded 10 million dollars. More and more customers trust us and to work with us, and we have also provided them with the most suitable products. With strong export volume and excellent customer feedback, it was selected as a certified supplier by Made-in-China.com.


Our company's main products: press brake, shearing machine and hydraulic press have obtained the utility model patent certificate certified by the State Intellectual Property Office. In the following years, the CNC press brake produced by our independent company obtained the appearance design patent certificate certified by the State Intellectual Property Office.


The press brake and hydraulic presses produced by HARSLE have obtained CE certification. We Participated in the 6th India BLECH Exhibition in the same year and attracted many overseas customers to place orders on the spot with high-quality machines and professional explanations.


The punching machine and shearing machine produced by our company have successively obtained CE certification. In the same year, the company participated in the Dubai exhibition and passed the ISO9001:2015 quality system certification.

Feature Blogs & Articles

HARSLE is a press brake toolings manufacturer and we will share useful knowledge about bending tooling every week. Because HARSLE has a professional engineering team, we will offer more various press brake tooling tips and knowledge to our users.


Arrow Punch

This type of mold is generally vertical with a relatively thin thickness, which is suitable for products to be bent from both sides.

Gooseneck Punch

This type of mold is generally used for folding groove type or products with greater depth requirements for the center of the upper mold.

Sash Punch

The elbow part of this type of mold is very narrow and is usually used for processing facades or door frames.

4V Die

The appropriate V-shaped opening width can be selected according to the bending thickness, and it can also be used with semi-circular notches.

Single-V die

The notch angle is generally between 30 degrees and 90 degrees. Compared with the multi-V die, the workpiece has more free space during the bending process.

Double-V die

Because the double-V lower mold is directly installed on the guide rail, there is no screw fixation, so the notch can be quickly switched.

asked questions

Press brake tools are used in conjunction with a press brake, which operates are heavy boom or press in order to shape and bend sheet metal. The press uses a punch to force the metal sheet into the die, creating a permanent crease and reshaping the metal. Press brakes and their accompanying tools operate without an external heating device; the heat and friction from the press' tools are enough to reshape the material. Press brake tools are usually steel, but other materials such as urethane do exist.

Many people believe that the press brake tools are some insignificant accessory in metal processing, where it is quite the opposite. Despite press brakes becoming multi-axial machine with high precision, it is the tools that come into contact with the metal during bending (see the image above).
The differences among the tools of RFA, Eueopean, American and new type of grip are being slowly vanishing. Many functions that are needed for high effective bending are now implemented into the various types of tools. Whatever style of tooling and grip you might choose, make sure it meets the minimum requirements listed below.

HCHCr steel is widely used in cold forming molds, press tools, and die making industries, primarily due to excellent wear resistance, high compressive strength, greater dimensional stability, and high hardness.
Generally, the materials of press brake die including T8 steel, T10 steel, 42CrMo, and Cr12MoV. Cr12MoV is also good material.

Press brake punches come in a wide variety of shapes and sizes, which one you choose for any given job, will depend on the job itself. There is a vast range available, although they can be generally classified into three unique types, Goose Neck Punch, Swan Neck Punch and Acute Angle Punch. There are of course sub-divisions of these three types,with different radius on the nose to suit different material thicknesses and some can even be made specifically by us at Selmach for the more bespoke and unique tasks such as joggle and curl tooling. Knowing which type is best for which application can and will pay dividends.

Press brake dies is a tool used by the press brake to form a sheet metal. This tooling consists of various parts, and the different toolings are made up of different parts. It mainly realizes the processing of the shape of the parts by changing the physical state of the formed material.They are also strong, typically crafted from materials such as T8 steel, T10 steel, and the more expensive Cr12MoV or 42CrMo for high strength, superior durability and the best possible resistance to wear and tear.
