Mr. Wittaya Manitchotiphisit, Chairman and Founder of Kollakij Ban Pong Company. Mr. Wittaya was originally born into a farming family that grew tobacco in Kanchanaburi Province. At that time, most farmers relied entirely on manual labor for their work. Mr. Wittaya had the idea that it would be great if labor-saving machines could be used on tobacco farms. When he was in his 20s, he left home and headed to Bangkok to train as a lathe machinist in the "city of angels." However, he couldn't find lathe work — only a job at an auto repair shop. After staying there for a while, Mr. Wittaya realized that he wouldn't make progress there, since the senior craftsmen guarded their knowledge and refused to teach him. He therefore decided to return home and open a lathe workshop in Ban Pong. Through his own diligence and perseverance, Mr. Wittaya taught himself lathe work — buying textbooks to study and practicing on his own. Starting from small jobs, the workshop gradually gained more work, and he eventually brought his father, mother, and two younger brothers to join him. Today, this has grown into a group of affiliated companies: Kai Heng Lee, Kai Heng Lee Machinery, and the Kollakij Ban Pong factory itself has expanded into two additional factories: Phatthanakij Ban Pong (which makes sugarcane harvesters) and Rungruangkij Ban Pong.
