in June 2002, StrongMetal signed a strategic cooperation agreement with the Swiss SOLO Group, becoming the company's production and manufacturing base in China, and at the same time as the general agent of SOLO in China to promote its products. For many years thereafter, the two companies exchanged engineering personnel for learning and training. So far, Shichuang Technology has sent 50 or 60 scientific and technical personnel to Switzerland for exchanges and inspections, and they have worked together to improve their heat treatment skills. The Swiss SOLO brand has become one of the well-known international brands of heat treatment equipment in China's military and aerospace industries.
