Metal 3D Printer

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

Eco-friendly Gas Insulated Switchgear for Electric Railway

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

This equipment is supplied to major Korean IT companies such as Samsung Electronics, LG Display, and SK Hynix as well as exported to countries including the UK, the USA, and France.
Semisysco started its electric car business last year and established an electric car factory in Sejong City for the first time in Korea in May last year. The city has been selected for being the multifunctional administrative city accommodating the Ministry of Land, Infrastructure, and Transport (MoLIT), the Ministry of Environment (ME), and the Ministry of Trade, Industry and Energy (MOTIE). Sejong City also has the highest population inflow of all cities in the country, and is close to many areas, while being an emerging city.
Semisysco’s lineup includes D2, a two-passenger compact car, U4, a four-wheeled micro freight car, and R3, a three-wheeled vehicle. The D2 travels up to 150km, the highest mileage on a single charge among the micro compact EVs available in Korea. It is equipped with an air conditioner and heater to suit the climate of Korea and has acquired L7, the European safety certification for microcompact cars. The R3 and U4 have the same vehicle structure and dynamics as a regular automobile and have an advantage of 25 to 30% uphill gradability.
Although it is not possible to disclose specific figures for pre-orders for the D2 received last year, the number of orders and the actual purchase rate are positive. The R3 and U4 are also aiming to launch in May and June this year, respectively.
Semisysco focuses on micro-compact models. The reason is that the micro car is a suitable model for the Korean environment and can also avoid competition with other big auto manufacturers. The advantages of a micro car include smallness in size, affordability, and free from the shortage of EV-charging infrastructure.
Since releasing the D2 in February, Semisysco started to yield profits in the electric car business. Currently, the model is manufactured by Zhi Dou (ZD), an electric car manufacturer in China. However, Semisysco plans to shift it to “Made in Korea” in the near future. The company has had this vision since it entered the electric car business. Semisysco expects its break-even point at about 200 units per year as of now.
