Core Barrels[INQ. NO. 2005M06] TaeSung Co. is a leading manufacturer of exploration drilling equipment for Korea and the surrounding region since 1980. Taesung is specialized in the production of high-quality impregnated diamond core bits, reaming shells, core barrels, casing, drill rods, and more.
Taesung’s Core Barrels are made of raw materials of best quality appropriate for drilling, so they have excellent lifespan and quality and are currently being exported to various countries such as Kazakhstan, Mongolia, Uzbekistan, etc.
Now there are many types of these barrels produced by the company – single tube core barrels, double tube core barrels, triple tube core barrels, and wire line core barrels.

The single tube core barrels are generally used to increase the collection rate of cores on an even ground. They cannot be used at the ground that can be easily collapsed or eroded by the circulation water.
The double tube core barrels are made of double tubes (outer tube, inner tube), and circulation water passes through the gap between the tubes and is not touched by the collected cores. They are not suitable to be used for the geological strata where core collection is difficult due to uneven strata with many cracks, coal beds, and soft layers. Also, they play a role of increasing the core collection rate.
The triple tube core barrels have almost the same structure with double tube core barrels, but tubes for the core case are built inside the inner tube.
The inner tube can be easily removed from a core case tube along with the cores taken into the inner tube.

It is a product that is made to collect the fresh cores without disruptions from the weak ground or broken layers where core collection is difficult with normal double core barrels.
The wire line core barrels are used to hoist the rods during the drilling and core collection works by the bits of Core barrels or at the time of bit changing.
The greater the depth of the hoisting works, the more becomes the number of the rods and the weight of the rods as well as the cost, time, and labor of works. In order to solve these problems, wire line core barrels have an inner tube that is fitted inside the outer tube, and hoist the inner tube onto the ground within the hole by use of wire rope. If you use this core barrel, the number of hoistings of the rods is reduced, and accordingly this is the most reasonable core barrel especially for the drilling of cores from deep layer.
As a long-lasting No.1 supplier in Korea over the past 40 years and a preferred supplier to many other countries, Tae Sung is committed to supplying its clients with only the best-quality products. | Blog Magazine of korean-machinery, brands and Goods

Cast-resin Transformer[INQ. NO. 2005M05] Cast-resin transformers are becoming more popular due to strict environment regulation and increased concerns over fire explosion. Enertech Co., Ltd. has developed and manufactured cast-resin transformers for 15 years to cope with market demand.

Enertech’s Cast-resin Transformer has succeeded in combining the advantages of oil-filled and conventional dry-type transformers, which are fabricated with an epoxy resin. The windings are completely embedded under vacuum conditions. This casting method makes it possible to ensure void-free epoxy penetration of both the inner layer and turn-to-turn insulation.
The cast coil with epoxy resin with non-flammable characteristics has a self-fire-extinguishing performance, to be free from a fire caused by electrical sparks.
The cast coil with epoxy resin with high electrical and mechanical strength is manufactured in a robust structure against an electro-mechanical force occurring during short circuit, external impacts, and abnormal vibrations.
The cast coil with epoxy resin has an enhanced dielectric strength and does not suffer from the deterioration of dielectric property due to humidity and the aging effects of insulating materials, even after a long term without maintenance.
Compact size and lightweight type can be embodied by designing and manufacturing the coil by casting in a high vacuum using epoxy resin and insulating materials with good dielectric strength.
The cast coil with epoxy resin has a high thermal time constant factor, and it can thus endure much higher overloads for a short period of time.
Low-loss and low-noise are embodied through the optimal compact design using silicon steel of low-loss and good-insulating materials.
The cast coil with epoxy resin does not suffer from the deterioration of an insulating property due to humidity and moisture, so it is easy to inspect and maintain a transformer including the coil.
Founded in 2003, Enertech has been providing energy-saving products to the global market. The enterprise is supplying power distribution transformers, ESS (Energy Storage Systems), and power-savers, and they are recognized as excellent products in technology and performance.

Metal 3D Printer[INQ. NO. 1812M07] 3D printing is attracting attention as a core technology to restart the heart of the manufacturing industry. In traditional manufacturing, liquefied metal is placed in a mold which becomes a cast when producing one part, and that liquefied metal should solidify in the mold.
However, 3D printing prints an object three- dimensionally based on a digital three-dimensional blueprint file so it actually reduces costs and shortens the processing time. Because of these advantages, it has risen as ‘a thriving segment’ in the manufacturing circles.
However, what 3D printing should get through to create a synergy effect with industries of various areas is ‘a limit to materials.’ It requires durability and precision, second only to outputs made with the previous manufacturing methods. The width of material applications needs to be widened to catch up with this.
PROTOTECH unveiled the metal 3D printer of Desktop Metal (hereinafter, DM) at ‘Korea Metal Week 2018’ held in Kintex, Ilsan, for 4 days from October 30 under the supervision of Korea Trade Fairs Ltd.
Section Chief Choi, Ji-yoon of PROTOTECH said, ‘the 3D printer of DM which will be available from next year, adopted the new technology which was developed using a similar method to that of the FMD (Fused Deposition Modeling) method, which showed a limitation when applied to metal. This technology that makes metal powder and binder like clay by mixing them will make it difficult for the parts to be realized when the CNC is to be replaced.”
The chief also explained that ‘the metal 3D printer of DM is safe and easy to operate, so non-experts can use it easily.”
Another industry insider there said, ‘we cannot focus only on the good side of the new technology. The metal printer of DM uses a method of releasing the binder which had played the role of a glue before, so I’m not really satisfied with its precision. This is another task that the 3D printing community needs to work on.”
It is true that there are a lot of things to get through including the ‘reduction of time,’ ‘reduction of errors,’ etc. until 3D printing replaces the previous industry completely. However, concerned industries have been constantly evolving by making the metal parts lighter, improving their precision and diversifying materials through technological development. | Blog Magazine of korean-machinery, brands and Goods

Eco-friendly Gas Insulated Switchgear for Electric Railway[INQ. NO. 1811M08] KEREC (Korea Electric Research Engineering Construction Co., Ltd.) is planning to become a total engineering company by expanding its business to the field of heavy electric machinery manufacturing. KEREC, having started as a company specialized in engineering such as design, supervision and construction of railroad, has carried forward diversification of its business model into heavy electric machinery manufacturing, such as distribution board, switchgear, etc. from years ago.
Recently, KEREC has completed development of KE-29GIS, an ecofriendly gas insulated switchgear for electric railways, which minimized the filling volume of sulphur hexafluoride, and now is taking the lead in the market in earnest. This product is a device used for the sectioning post and auxiliary sectioning post for the power supply system of the electric railway, power plant, substation, etc. The characteristic of this product is that as it is embedded in the metal enclosure such as circuit breaker, disconnecting switch, etc., the stability of the facility is secured.
KEREC plans to discover new markets by participating in a tender of Korea Rail Network Authority from the latter half of this year. In particular, as broadscale projects of improvement and repair are anticipated to be ordered due to deterioration of the railway facilities, the utilization rate of KE-29GIS is expected to be even higher.
Seong-Oug Lee, President & CEO of KEREC, commented, “Expectations are high due to the situation where safety and environment are being emphasized and SOC-related improvement and repair orders are being expanded. Demand is likely to increase more if related businesses such as the North-South railway project get started in earnest.”
At the same time, the 25.8kV eco-friendly switchgear under development is also noteworthy. This product, planned to be completed next year, is expected to become a stepping stone for KEREC to advance into the overall electric power industry, including KEPCO projects.
KEREC’s efforts to expand into heavy electric machinery were affected by the recession in the electric railroad engineering sector. In recent years, the electric railway sector has been slowing down due to overall reduction of the business. Therefore, KEREC has selected the heavy electric industry as a sector in which it can combine the technologies and capabilities accumulated in the engineering sector.
CEO Lee explained, “We are a professional company owning as many as 20 professional engineers and doctors of engineering rarely in the industry. I thought that there will be enough chance of winning if we combine the experiences accumulated for the time with the manufacturing business.”
In addition, KEREC is planning to be reborn as a total engineering company in the electric power field by considering advancement into the new, renewable energy and energy storage system (ESS) as well as heavy electric machinery. Research and development of a microgrid combining the distributed power sources such as photovoltaic and wind power with ESS is now underway, and the outline of the project is expected to be unveiled by the end of next year. CEO Lee said, “We aim to become a total engineering company by expanding our business range into the heavy electric machinery manufacturing based on our technological prowess in the electric railway. We will contribute to development of the industry with continuous technology investment and training of human resources.” | Blog Magazine of korean-machinery, brands and Goods
