HANSUNG started as Saehan Company in 1978 and specializes in producing and exporting oil seal, o-ring, and cylinder packing.

Then we have grown into a leading company in the domestic sealing industry.

Our company is taking the lead in R&D to replace overseas sealing products with domestic products.

From 1978, we have accumulated technical know-how in the production of sealing products, had a large number of molds, and eventually grew into a technology-leading company.

HANSUNG completed the construction of smart factory system facilities to improve the process capability of the product and minimize the defect rate.

Furthermore, we can meet a customer needs and maintain high quality at the same time.

We continue to invest in research and development to develop sealing products suitable for new industries.

We will grow into a global company that innovates sealing products.
