As a leading manufacturer of precision parts in China, Gian Technology's customers include Samsung, OPPO, Vivo and other well-known enterprises. They have very high requirements for the precision and appearance of products. Every year, Gian invest a substantial amount of capital in manpower and capital in quality control and quality inspection. The "original" method of the traditional naked eye + magnifying glass is intensive and boring, making many young people reluctant to choose this job. The gap between business volume and manpower is getting bigger and bigger, and it is difficult to meet the quality inspection needs in three shifts and eight hours. Overtime is a common occurrence.
