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

HANSBAR is the brand name of cast iron bars produced by HANS Materials Inc. since 1991 through a horizontal continuous casting process.
Due to the dense microstructure and the extreme suppression of defects, HANSBAR shows superior characteristics when compared to conventional sand-casting products. Furthermore, when compared to steel with similar mechanical properties, it delivers excellent machinability, with superior noise and vibration characteristics.
HANS Materials seeks continuous improvement and innovation to ensure world-class products. This, combined with strict adherence to basic production principles and dedication to satisfying the customers, ensures the high integrity of HANSBAR.
The molten iron held in the concast holder provides a large head of iron above the graphite die, thus reducing the risk of internal shrinkage defects in the pulled bar, whilst also allowing the lighter impurities in the iron to float upwards in the holder. This ensures homogenous material properties in the finished product.

Due to its excellent quality and mechanical properties, HANSBAR is being applied to critical components across various industries – such as for pneumatic and hydraulic parts, rotors for high vacuum pumps and compressors, gears and shafts for automobiles. By adopting HANSBAR in your products you will immediately increase your competiveness in your market.

HANSBAR is produced in round, square or rectangular shapes. HANS Materials Inc. is the only manufacturer of continuous cast iron bars in South Korea, and as such they can be produced and supplied according to the material properties and sizes required by the customer.

A spokesperson for the company commented, “Our technical team will suggest the optimum solutions to your problems.”

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

Oxygen therapy is a treatment that restores oxygen saturation and improves survival rates by supplying medical oxygen of 90% or more purity to patients whose blood oxygen saturation is excessively low due to respiratory diseases.
In general, the medical oxygen generator is a facility that continuously discharges high-purity oxygen and supplies it to a patient’s oxygen breathing device through a gas facility in a hospital.
As a system built to replace the continuous supply of liquefied and high-pressure oxygen to the central gas piping system used in medium, large hospitals, and nursing clinics, OXUS’s RAK-U06M2E medical oxygen generator can continuously operate and supply oxygen to the central piping system for 24 hours, 365 days per year.
RAK-U06M2E can supply uninterrupted oxygen with continuous oxygen generation. It ensures excellent cost savings compared to normal liquid oxygen.
The model contributes to space saving by eliminating the need for high-pressure vessel storage. It can also save maintenance costs by not using high-pressure cylinders. Even if one unit fails, the equipment does not turn off.

OXUS unveiled its new oxygen generator at the 2025 KIMES exhibition. With 25 years of experience manufacturing oxygen generators, OXUS possesses proprietary PSA oxygen process technology. It currently holds a dominant market share in the domestic medical, healthcare (wellness), and aquatic oxygen generator sectors. At this event, OXUS showcased two healthcare oxygen generators and one portable medical oxygen generator.
The healthcare oxygen generators continuously supply high-purity oxygen (over 90%) at up to 1 liter and 3 liters per minute, respectively. User convenience was particularly emphasized. Users can adjust purity, flow rate, and run time by using a large light-emitting diode (LED) touchscreen.
