[INQ. NO. 1912M20] Daesung Hi-tech Co., Ltd., established in 1995, started its first business with Yamazaki Mazak by supplying high-precision parts in 1997. It has been highly acknowledged as one of the companies having top class technical skills in the Japanese market over the past 20 years.
Daesung Hi-tech exports such high-quality parts to a variety of countries such as Japan, the UK, Singapore, etc. As much as 85% of its profits are being made from exporting goods. Moreover, Daesung Hi-tech acquired AS9001 (Aerospace quality certificate), which makes it competitive in the aerospace market.
Its main products are high-precision parts, units, jig fixes, high-precision ass’y, automatic lathes, hobbing machines, and tapping centers.
Index Coupling (Hirth Type)
This is the device used for delivering the rotation from one shaft to another. It is different from the clutch, and it is impossible to cut the delivery of power randomly during the rotation as it connects the two shafts directly. It is classified into the fixed type that connects the two shafts semi-permanently, the movable type that somewhat allows movement between the two shafts, and the retractable type that is used when the two shafts form a certain angle.
Daesung Hi-tech’s coupling, being self-developed is exported all over the world including Japan. This product is used for splitting positions of such equipment as the index table, NC lathe, turret device, etc., and is convenient for semi-finishing due to excellent durability and high-power delivery.
Spindle Spacer
Spindle spacer is a spacer for fixing the spindle bearing which is the core of the machine tool, and it is a high precision product requiring up to 0.001 parallelism; applicable to various kinds of spindle bearings.
Collet
Collet is a part for fixing a drill or an end mill, and there are multiple grooves on the cylinder-shaped barrel of the collet. By tightening the barrel with uniform force from the outside using the screw, the collect is tightly fixed to the drill or the end mill which is inserted into the barrel.
Daesung Hi-tech’s collet is a unit part for fixing the M/C seal that is a functional product which is complex in the process of each part and requires high precision.
As of 2018, with the aim of diversifying its current field of business, Daesung Hi-tech is emphasizing its capability and influence – not only in the field of machine tools but also in the field of other industrial machines – in order to make much more profit, as well as to take a huge step forward in the various industrial markets.

As HIMC processes its hydraulic cylinders with self-produced SRB (Skiving Roller Burnishing), they have better durability and working performance than existing products. The company is producing tubes up to Ø 250 mm of bore, 3000 mm of length, and 750kgf/cm2 of test pressure. Contamination level for cleaner and hydraulic fluid is managed in NAS (National Aerospace Standard) class 7, and measured periodically, once a week. Because the company has its own manufacturing for head covers, rod covers, pistons, and parts required in manufacturing hydraulic cylinders, it has a system that can respond in a timely manner, even for small quantity orders.
TECHCROSS Inc. has been setting setting records such as succeeding in the installation of an explosion-proof product for the first time in the world, and of VLCC product for the first time in the industry, and conquering the global market with excellent product performance and installation know-how. It obtained a type approval from USCG in June 2018, the first in Korea which is expected to become a new solution for continuing long-term recession in the marine equipment industry.
Recently, TECHCROSS Inc. developed an indirect treatment system besides the treatment system using a direct electrolysis method, and maintained a systematic AS service system to quickly respond to customers’ enquiries related to the approval and product operation.
And, each of the five molds could be replaced separately as well by designing and manufacturing the car accordingly, if needed.
This bimetallic thermometer with specifically high resistance against vibration is receiving favorable responses from overseas customers, and is applied mainly for high temperatures like 650°C, not only to marine engines but also to power plants, general industrial purpose engines and medium/small-sized engines, and is suitable for measuring a wide range of temperatures such as 60°C, 100°C, 150°C, 200°C, 250°C and 320°C.
Radiators used for generators are mostly made out of copper, brass and aluminum and could be designed and manufactured as long as cooling data and site conditions of engines are available. We are capable of designing and producing radiators for high-speed engines (Doosan, Caterpiller, Cummins, MTU, etc.). We are also producing and supplying customized radiators for middle & low-speed engines (Wartsila, MAN, Himsen, etc.) and gas & middle-speed radiators to cool down all types of engines (diesel and gas engines) used for power plants.
We have recently developed and provided air coolers not only for generator engines, but also for hydrogen fuel cells and hydrogen compressors.
Costal is manufacturing some 2,000 types of products for over 200 customers at home and abroad. It is also capable of providing various types of coated, plated and insulated products.
Costal, as a metal-processing company, is manufacturing varied products including copper & aluminum branch sleeves, C-type sleeves, copper busbars and copper rods for distributing boards, casting lugs for substations, radiator panels and IGBT heat sinks used for vehicles, hydraulic and mold-type transformer parts, distribution box lugs and others.
Starting with the agreement, Costal is planning to advance not only into the Japanese market, but also into the German, Australian and European markets. By doing so, it has a medium & long-term plan to increase its exports which are currently standing at around KRW 1.7 billion up to KRW 3 billion.
The technology is widely applied to cast-iron molds, press molds, gears, rails, rings and vehicle parts and industrial machine parts.
As the laser-based technology requires less energy and neither water nor oil for cooling the heated metal surface, it is coming into the spotlight as an eco-friendly, new laser hardening that leaves the work environment and applied metal surface clean.
In addition, the Korean-Type Soft Top Wing Van developed by Hansung Special Equipment in co-operation with Europe uses loading and unloading space as efficiently as possible and lowered the weight of its body, thereby maximizing its payload and pruning fuel costs.
Hansung Special Equipment’s wing van which has dramatically lowered logistics loading and unloading and maintenance costs, and the Cold Chain Optimization Solution through quick freezing technology create value optimized for the domestic and overseas logistics markets.
