Innovation is CHNCON inherent gene
Since the beginning of 2001, zhengkang has continuously invested in scientific research and production without stopping.Tens of millions of yuan are invested in scientific research and improvement of production facilities every year.
Whether we own the independent intellectual property rights of the bulge connection technology, or the introduction of press fitting connection technology from the overseas, and later we developed the welding, groove and other connection methods, we are on the basis of the original technology, constantly improve, to upgrade the technology, making the product performance greatly advanced.
In addition, from the aspect of manufacture, in order to meet the increasing market sales, zhengkang constantly optimizes the production equipment. Some of the production equipment have obvious defects in the market. We will design the equipment performance and improve the equipment performance jointly through the scientific research staff and the joint production equipment manufacturers.
Since the first factory building was built, zhengkang has expanded the factory building four times to furtherly meet the market demand.
Through innovation, zhengkang has always placed its products in an active competitive position in the market competition.
