Our company has been established for 40 years since 1966. In the early years, we mainly produced small types of scales and thus accumulated experience related to such product. Upon the faith of pursuing upgraded improvement, we started to produce large mechanical scales and owned the very first factory. In 1981, the company decided to get involved in the development and production of automatic measuring packing machines and launched the factory in Thailand. We thus covered over 30% of the market in Thailand. In 2002, the company also succeeded in the application of the patent of two types of automatic measuring packing machines.
