We specialize in a wide range of machine tools, including electric shearing machine, plate bending machine, pipe bending machine, hydraulic press machine, and more. Over the past 40 years, we have gained much experience and placed it into the creation of quality products. Hence, our metal working machines are reliable, accurate, and cost effective, and are popular with customers from Europe, South America, Southeast Asia, the Middle East, and North Africa.
We have been in machine tool business for over 40 years. After continuous improvement on our production and management system, we are now able to produce a wide range of plate bending machine and shearing machine which are competitive in the market.
As an experienced shearing machine manufacturer in China, we provide quality built guillotine shearing machine, swing beam shearing machine and electric shearing machine. Our shearing machine is a metal forming machine primarily used to cut aluminum sheets, steel plates or copper plates without the formation of chips or the use of burning or melting. It is commonly applied in aviation, metallurgy, chemical, construction, shipbuilding, automobile, electric power, decoration, and light industries.
In addition to its enough shearing force supply, our guillotine shearing machine is known for its wide range of shearing thickness and width. The deformation of the shearing piece is greatly reduced due to variable shearing angle. Protection fence is also available to ensure the security.

A press brake, also called a brake press, is a machine tool which is primarily used for bending sheet metal. As an experienced press brake manufacturer in China, we at Donghai provide several types of brakes, including NC hydraulic press brake, CNC hydraulic press brake and tandem CNC press brake etc.
Thanks to the use of mechanism compensation system, our hydraulic press brake provides higher bending accuracy. In addition, punching tools and lower die can be specially designed to meet specific workpiece requirements.
Our NC hydraulic press brake operates by means of two hydraulic cylinders on the C-frames moving the upper beam. The steel welded structure, coupled with high tensile alloyed punching tool, helps ensure the durability of our press brake. Additionally, DA-41 NC controller from DELEM Company, DNC60 NC controller from ...
In addition, the use of BOSCH hydraulic oil pump and SIEMENS main motor helps ensure the performance of our products. Furthermore, the accuracy of the workpiece is also guaranteed because our press brake can automatically carry out all operations according to the preset procedures.
Our tandem CNC press brake is specially designed for extra long pieces, such as a piece with length over 8000mm. This fabricating equipment is widely used for forming the lighting pole, launching tower, heavy truck beam, etc.
1. Plate bending machines should be managed and operated by a specialized person. Meanwhile, it is a necessary to make sure that the operator is familiar with the equipment performance and know well how to use the machine.
2. Before starting the machine, please double check and make sure that safety devices are in good condition.

This four roll bender is designed to pre-bend and coil steel sheets and metal plate in industries like pressure container making, hydroelectricity, and architectural, etc. Both coiling and leveling functions are available.
W24S angle bending machine, a type of three-roll double-pinch bender, is designed with one fixed roll and two movable rolls. The rollers can be adjusted to bend materials symmetrically or asymmetrically and pre-bend both ends of the workpieces in a single pass.
A hydraulic press machine is a machine which is designed for drawing, forming, bending, straightening and mounting applications. It uses a liquid as the working medium. Presently, the hydraulic press machine is used for almost all industrial purposes. Basically it is used for transforming metallic objects into sheets of metal in industries such as aviation, automobile and pipeline.

A leveller is a device that can be used for the straightening of metal section, bar, wire rod and tubular product, just to name a few. It uses leveling rolls to extrude the bar materials or other metal materials to change their straightness. An uncoiler is a device that can hold coil and gradually decoil it during the course of press operations. The straightener and decoiler are usually configured into a leveller-uncoiler to produce metal plate or other sheet materials.
