Weihai Runtong is a company specializing in the production of rubber products. Its main products include inner tubes, air springs, and rubber tracks. It has a history of more than 30 years, has more than 1,000 workers, and has a professional R&D and design team. Inner tubes are mainly supplied to large tire companies, with sales of 500-600 million yuan per year. It is the largest inner tube manufacturer in China.

Again, based on this, we developed air springs and rubber tracks. Because we started late, our technology is relatively mature and our equipment is relatively advanced. Compared with old manufacturers, our production efficiency is more higher. Moreover, we have good rubber raw materials and we are the only company in China that has its own internal mixing workshop and calender, so that we can produce the cord fabric for air springs by ourselves, this operation can effectively control the cost.

 Moreover, we have advanced experimental equipments, and our products must undergo strict blast testing, fatigue testing, and air tightness testing before leaving the factory. Ensure that every product meets world standards.
