Since 1980, Dongjin Machinery Co., Ltd. has been the leader in hydraulic bench presses in Korea. Under its slogan, “Be Honest, Faithful and Accurate, Dongjin has been keeping its promise to satisfy its customers’ expectations with the best quality.
Dongjin has produced small and compact hydraulic presses for inserting, caulking, trimming, blanking, stamping, coining and etc.
The bolster size, the open height and stroke can be changed according to the the customers’ requirements.
Dongjin’s hydraulic bench type presses’ strength is highspeed and high-precision. Dongjin press is very efficient due to the two different stages (Approach (High Speed range) and Press (Low Speed range)) of RAM speed.
Dongjin presses’ differential piston function makes the press work two different stages of ram speed. Its differential piston function is the ram speed increase by the working fluid increase which happens by the difference of the cross-section area of the upper piston rod and lower piston rod.
Dongjin developed control box can set the pressure time and pressure power easily and the operator can set the jig fixture by its 3 operation mode(manual mode, inching mode and auto mode).
It can be safely operated with two hand button switches and an electronic safety device. Its compact size makes the installation easier. It makes low noise and there is less vibration.
There are several options for Dongjin Hydraulic presses which are opto-electronic safety device, cooler (Ait/Water ), heater, pressure switch, throttle valve, guided ram. Load cell and so on. The open height and stroke can be adjustable depending on the customer’s request. Dongjin’s presses have acquired KCS certification and CE certification for safe operation.
Dongjin’s reputation as the masterpiece of machinery has been spreading not only through the domestic market but through the overseas market. Dongjin Machinery started its business with pneumatic press and booster cylinder press, and it soon has expanded the product to hydraulic press and servo press.
PCDF process and accumulated experience bring the trust of its machines. Dongjin’s spirit toward masterpieces of machines is its responsibility for the customers and its R&D investment for the future is its competitive power for the customers. Now all the presses are exported to the United States, China and Southeast Asian countries.

1/2~16 inch), longer lifetime than steel valves, and environment-friendly material (Polyethylene is safe for the human body).
ingredients from indoor spaces to get rid of odors. Fourth, as an additional convenient function, it relieves stress and enhances immunity utilizing natural essence, and performs access blocking function instead of killing mosquitoes. In addition, it passed the A1 class test for fi re resistance, which is stricter than class 1 nonflammable materials, and the emission of radiant matters like recently highlighted Radon is hardly found (Radioactivity index based on Environment Product Declaration is 1.0, while that of IECO block is 0.043).
where many people spend most of their time.
LB&PCK’s forged and casting valves met international standards such as ANSI, DIN, API 6D and ASME B16.34.
Strainers are devices which arrest these solids in flowing liquids or gases, and protect equipment from their harmful effects, thus reducing downtime and maintenance.
LB&PCK Co., Ltd. utilizes both the spiral weld and rolled and welded methods of manufacturing for large diameter double-submerged arc-welded pipes. The spiral weld pipe is manufactured in sizes of 12-inch through 156-inch OD and wall thickness of 0.105-inch through 1.00- inch.
Based on its leading-edge technological process, SOOSAN hydraulic breaker boasts a strong hitting power with the highest power-toweight ratio in its class, guarantees the durability by installing a built-in valve, and saves the maintenance cost with composition of parts of about 80% level compared with other companies.
SOOSAN crane dominates domestic market share of the truck-mounted crane regardless of the type of domestic and overseas commercial trucks with excellent mounting performance and the largest product lineup in Korea. SOOSAN crane, which guarantees excellent lifting capacity and durability with convenience capable of lifting work only with easy operation, crane boom design technology of the minimum weight in the same class, and selection of high-tensile-strength boom, minimizes shaking of the boom while in operation through the technology of minimizing the gap between booms.
SOOSAN hydraulic drill is equipped with a drilling capacity and control system that can optimally respond to various qualities of rocks or changes of working conditions with its independently developed drifter technology by utilizing the core technology of SOOSAN Breaker accumulated over the past 30 years. Like this, SOOSAN hydraulic drill with excellent drilling efficiency has better fuel consumption rates than other domestic and foreign competitors, has outstanding work capacity even in the environments of bare ground, tunnel and special work environment.
You need not purchase a storage box separately as there is a separate storage space in the conventional bag that can be quickly installed and disassembled, thereby facilitating portability. This product can even be used as a fishing rod rack after being installed on the waterfront. Using this product, you can cook various foods even in a narrow space.
Most of the sites using the flexible packaging printing machines such as gravure printing, dry laminating, coating machines, etc. have difficulties in systematic management and process improvement after initial installation of the machine. They manufacture their products only based on the intuition of the workers having long-time experience with no exact figures on how the air actually flows into the chamber during the drying process and whether the balance between exhaust and intake is properly maintained.
The characteristics of the product are the flow control capability, which is an advantage of globe valves, and a simple structure that is a merit of ball valves. This product has solved the shortcomings of globe valves, which are expensive, relatively low flow rate, the cavitation phenomenon caused by the bent pipe and generation of noise and vibration, and the disadvantages of ball valves including sludge inflow between ball and body and seat ring breakage in the fluids containing fiber (paper pulp)-like sludge at the time of valve locking.
by vision. The company also possesses the vibration and shock test equipment required by the OEM customers additionally as well as geometry, photometry, life test equipment and temperature measurement equipment, thereby strictly checking the bulb quality against the damage that may occur when the bulb is mounted on the vehicle.
As shown in the image, Sindo is a company specialized in manufacturing cold forging products. In order to satisfy the diverse needs of its customers, Sindo has more than 20 former facilities ranging from 80 tons to 2,220 tons, In particular, 2,200 ton former facility it possess is a facility uniquely owned by itself among global cold forging companies. In addition, as its strength, Sindo has 13 knuckle press facilities ranging from 150ton to 1,500ton that can meet the size and specifications required by the customers by 99% or higher.
itself are always supplied and, for the products exported overseas, 100% inspection is carried out by automatic inspection machine.
