https://korean-machinery.com///inquiry

[INQ. NO. 2408M23] Tae Sung Co. was founded in 1980, and is currently a leading company in Korea in diamond core bits. It is the only company in Korea that can provide total solutions for impregnated core bits, reamers, drill rods, core barrels, and drilling accessories.
Tae Sung has approximately 600 domestic customers and is currently exporting it top-quality products to more than 27 countries.

Impregnated diamond core bits
Impregnated diamond core bits are attached to the foremost part of the core barrels to be used in direct drilling of the ground, and play the most important role among the equipment that are used in drilling. There are many types of bits classified and used according to the purpose of drilling or ground conditions, and the bits also differ in terms of their material, shape, and performance.
It is thus economical and highly effective in drilling works to use the proper bits after full understanding of the characteristics of each bit. Impregnated diamond core bits are used for the drilling of hard rocks, and metal bits are normally used for the ground or soft rocks.

Impregnated diamond core bits are normally used in cases where core drilling is needed, while non-core bits are used where core is not needed. However, the drilling efficiency and economic feasibility increase if core bits are used while core is not needed.
Due to the global trend of moving toward a carbon-free era, the demand for mineral resources such as electric vehicles and batteries is expected to steadily increase in the future. Accordingly, the demand for diamond coring products produced by Tae Sung will also automatically increase, so the outlook is bright.

Diamond reaming shell (reamer)
A diamond reaming shell is connected with a bit to be used, and the drilling by bit and grinding of side surfaces can be done simultaneously, but the drilled hole should be kept not smaller than the diameter of the bit (reaming).

It should be used to prevent early wear and tear of the outer diameter of the bit, and also to prevent vibration and deformation of the hole walls. Diamond reaming shells are produced with the outside diameter larger than that of the bit.
There are two types of diamond reaming shells — one is for general rocks, and the other is the screw-type for strong rocks.
Taesung’s diamond reaming shells have an excellent lifespan and reaming ability as high-quality shank and natural diamond are used in producing them.

Syringe-Manufacturing Machines

August 21, 2024 by Leave a Comment
https://korean-machinery.com///inquiry

 [INQ. NO. 2408M20] The syringe-manufacturing machines of JEESUNG Engineering include a chain of machines that print the markings onto, assemble, package, and sterilize the syringes that we usually see at the clinics.
The machines manufacture general (conventional) syringes of different sizes, including 3ml, 5ml, 10ml, 20ml, etc.

The machines also manufacture some special syringes, such as the 1ml uni-body insulin syringe for diabetic patients, as well as auto-disable syringes, and safety syringes.
These syringes have different purposes. The auto-disable syringes are designed to be automatically disabled when someone intends to use them the second time (by breaking the piston when pulled, etc.) to prevent infection by blocking any attempt to use it more than once.
The safety syringes are designed to protect the medical staff from accidental infection. They are specially manufactured so that the needles will retract into the syringe after use and will not puncture the skin of the medical staffs.
In general, syringes of different sizes are manufactured by: the parts (barrel, plunger and gasket) of different sizes being manufactured by injection; the marks being printed onto the barrel; and the parts being assembled.

The process of syringe-manufacturing
When the machines assemble the parts into the completed products, they are blister-packaged, placed into cartons, and (as the final process) sterilized by the EO sterilizer so that they can be used on human patients at the clinics.
All these processes are carried out by a chain of machines (mold, injector, printer, assembler, and packager), called syringe-manufacturing machines.

Safety Valves

August 21, 2024 by Leave a Comment
https://korean-machinery.com///inquiry

[INQ. NO. 2408M19] Il-O-Sam Co., Ltd. is a company that has been specializing in the production of valve fittings through forging and processing brass materials since its establishment in 1985.
Il-O-Sam developed the cut-off overflow valve to prevent secondary accidents in the event of a large shock such as an earthquake or fire. This product can significantly reduce accidents with gas cylinders by preventing accidents through the valve’s own function in situations where people cannot do anything.

Cut-off overflow valve
The company’s cut-off overflow valve built into the safety valve can be used for LPG/propane gas for household and restaurant use. The conventional safety valves cannot automatically cut off the flow of gas when an earthquake, fire, severe shock, or accident occurs, affecting the tank, hose, or combustion unit.

The Overfill Prevention Device (OPD) valve developed in the United States has the limitation that it can only be operated when the pressure regulator is removed. However, Il-O-Sam’s cut-off overflow valve is designed to operate automatically in the event of a gas pipe rupture (above the allowable level).
The cut-off overflow valve disconnects the pressure regulator and automatically cuts off the gas when the valve is opened. This product also has such additional functions as automatic gas shutoff if the pressure regulator is accidentally separated or detached from the hose during use; automatic gas shutoff if the gas supply line (hose or pipe) is cut or ruptured; automatic gas shutoff if the LPG cylinder falls over due to an earthquake or impact; automatic gas shutoff if the valve itself is defective or damaged by external impact; and automatic gas shutoff if the pressure regulator is damaged during use.
The cut-off overflow valve is installed inside the valve (embedded type) and costs only about 10% of the price of the existing valves. Therefore, by simply adopting the company’s overcurrent blocking component to the existing OPD valves, users’ products ultimately can be upgraded to the best safety valve.

https://korean-machinery.com///inquiry

[INQ. NO. 2408M18] YUSEUNG Co., Ltd. was established in 2011, and has since been developing EGR cooler parts and powder metallurgy parts for internal combustion engines. YUSEUNG is a company that develops magnetic inductor cores and materials for power-conversion devices.
YUSEUNG recently began developing inductor cores for the On Board Chargers (OBCs) of electric hydrogen vehicles and hybrid vehicles, and confirmed delivery to Hyundai Motor Company in 2026.
YUSEUNG has a mission to ‘lead the way to energy-efficiency improvement through innovative technology and product development to reduce energy loss that inevitably occurs during power conversion.’
“We plan to expand our business to inductor core products in the future, leading the way in accelerating the transition to sustainable energy,” remarked the company’s CEO.

Inductor Core
An inductor is one of the three passive components that make up an electric circuit. It is made up of a core made by molding a soft magnetic powder material, and winding a conductive coil (wire) around it.
An inductor temporarily stores energy in the form of a magnetic field in the coil and acts to block changes in the current passing through it, and its size is determined by inductance, which is the ratio of electromotive force to current change (unit: henry, H).

Inductors are essential passive components that make up power circuits, and they play a role in smoothing the current and controlling noise in power circuits. They are also essential components used in power-conversion systems of power-driven devices such as electric vehicles.

Powder magnetic cores
Powder magnetic cores are manufactured by compressing insulating-coated metallic magnetic powder that has uniform voids distributed between the powder particles.
This unique design results in minimal magnetic flux leakage and high insulation proper-ties between the powder particles, thereby making them suitable for low-loss applications even in high-frequency environments.
