About

PTC ASIA 2014 is scheduled to open from October 27 to 30. Statistics indicate that this year’s exhibition will have an unprecedented scale.The exhibition area totals 85,500 square meters, but it is still unable to satisfy the market demand, although the exhibition halls have reached a 110 percent utilization rate.

Despite its eminence, PTC ASIA sticks to its original purpose: to showcase innovative technologies and products and become the most effective platform of communication, exchange and cooperation for enterprises and users.
