Discovery of dynamic sensors on the battlefield

While examining the wreckage of a US bomber that crashed in a Tokyo air raid during the Pacific War, a Japanese military arsenal researcher Hayashi found numerous insect-like objects attached to the wall inside the burnt plane. After research, he found out that the object was a strain gauge, a mechanical sensor used in structural engineering experiments, and Japan started a business based on this technology.
In 1983, after a long period of persuasion, CAS had received technical advice from Hayashi on strain gauges, which became the basis for our own development of strain gauge.

Development the world's first CNC RING ROLLING MACHINE

CAS, a venture company that started with the dream of developing a robotic machine in 1983, succeeded in developing the world's first CNC Ring Rolling Machine (8 meters in height and 35 tons in weight) that produces metal tires for trains in full automation with KAIST. It was the first attempt for CNC machine for the area of ring rolling field in the world.
Afterwards, using the core sensor of the machine, the load cell technology was further developed and distributed into various industry including the humanoid robots with multi-axis load cell.

Changing the scale culture (CAS Scale is good for both customer and vendor)

In 1985, CAS succeeded in developing various electronic scales and challenged the retail market. At that time, analog mechanical scales measured everything, and there were many difficulties in pioneering the market, because the vendor preferred conventional scales that were easy to manipulate rather than accurate electronic scales.
In response, CAS campaigned with the phrase, "use of accurate electronic scales will earn trust from customer, so it is also beneficial for vendor." It took almost 10 years, but CAS have changed scale culture. Currently, CAS is the No. 1 distribution scale brand with more than 75% of the domestic market share.

World’s first export of the electronic scale – Portugal

In 1987, CAS began to challenge the global market beyond the domestic market.
It was the first in the world to export electronic scales to Portugal. However, the challenge was not easy.
Scales are managed through regulations for weighing verification in each country, but at that time, Portugal did not have a regulation on weighing verification for electronic scales. CAS cooperated with the Portugal weighing department for 8 months of education and establishing weighing regulations to successfully export electronic scales. CAS continues to keep working together with Pedro Proto ever since for the past 36 years.

Transcontinental Road Trip of the Asia Continent (from Mt. Baekdu to Istanbul)

Celebrating its 10th anniversary in 1993, CAS challenged to cross the Asian continent, a whopping 15,000 km from Cheonji, Mt. Baekdu to Istanbul, Turkiye.
Looking forward to the new decade of CAS, with the goal of becoming the world's largest weighing company, the CAS expedition successfully crossed inland Asia, Silk Road, the ancient trade route that connects China, Western Asia, and the Mediterranean region.

Challenge the international accredited weighing certifications

In the 1990s, CAS focused on entering the global market and faced international certification for weighing. CAS had been approved by NTEP (National Type Evaluation Program) certification in 1990 and OIML (International Organization of Legal Metrology) certification in 1994, and continued to expand in the global market.
CAS Galileo House, established in Yangju in 1995, represents the starting point for entering the global market. CAS Galileo House was named after Italian astronomer, mathematician, and physicist Galileo Galilei, and it is where the development and production of weighin and measurement take place.

Weighing History - Emile Bell

In 1997, CAS measured the weight of the Emile Bell (Bell of King Seongdeok), the best Buddhist temple bell, first time in History.
The Emile Bell, completed in 771 A.D., has been estimated to weigh about 20 tons. According to the records of the Heritage of the Three States, it was made of 120,000 coppers ‘geun.’
It was the first time in over 1200 years that CAS measured the unknown weight of the Emile Bell. We had spent a year developing customized measuring instruments and tools, and finally, the measurements revealed that the bell weighed 18.9 tons, equivalent to 15 mid-size cars.
As a result of this measurement, one ‘geun’ from the Silla Dynasty period could be estimated to be 157.6 g when converted into modern weights.
With an accurate weighing solution, it was an opportunity to discover the weight of national treasure, and to rewrite the history of the unit of weight.

Weighing in harsh environments

CAS provides customized solutions optimized for harsh industrial environments based on strain gauge and load cell sensor technology through independent R&D.
CAS, which has acquired various certifications including explosion-proof and dust-proof since 1998, is used in industrial facilities requiring explosion proof rating, semiconductor manufacturing facilities, automobile, and ship industries, for high-temperature, vacuum, and multi-axis, measuring small-capacity miniature special load cells to hundreds of tons.
We develop, produce, and distribute customized solutions.

Weighing the world's largest aircraft - A380

In 2012, CAS was the first to weigh the world's largest passenger aircraft, the A380. Managing the exact weight and position of the center of gravity of an aircraft is the most basic process in aircraft management.
It is also very important for fuel saving and economical operation.
The W380 was developed with proprietary technology of CAS, and it is a portable weighing device designed to measure the exact weight and accurately.
The weight of A380 was measured to be 281,456kg (around 282 ton).

Establishment of Global production base & Galileo Academy Center

In 2013, CAS established a global production base in Zhejiang, China, which is the world's production plant for electronic scale. It was built to as a strategic production base to supply the highest quality products. We are developing and producing products necessary for various industries from core sensors to sensors used in automation solutions. In 2015, CAS had updated the facility with automated production and is now providing one stop solution for production and calibration for industrial products.
In addition, the CAS Galileo Academy Center is a place that trains professional marketers around the world through Galileo marketing education providing accommodations with leisure and sports facilities, and restaurants where global marketers would enjoy.
We plan to train 12,000 global marketers in the future, and we are equipped with various practical training ready for different sites.

Visiting Customers CMO - CAS Mobile Office

Since 2020, CAS is providing a CMO (CAS Mobile Office) service that visits customers based on regions assigned to provide faster customer service.
CMO service is an activity that manages products through periodic customer visits maintaining reliability.
This will ensure customer satisfaction.
The CMO service, which started in Korea, is currently being expanded to overseas branches and is expected to serve as a bridge connecting national and global companies beyond the region.

CAS Vision 2023 - CAS SFC (Smart Factory Complex)

In 2023, CAS is preparing to establish CAS Smart Factory Complex on a 20,000㎡ site in Gimhae Techno Valley to celebrate its 40th anniversary.
In line with the 4th Industrial Era, CAS plans to reorganize our business portfolio with sensor-oriented smart factory engineering and grow into a central hub of smart factory technology in Korea that provides customized solutions from the development of automation facilities in various industries requiring big data based on sensor technology. This is the future vision of CAS.
