More than 20 large-scale tire manufacturers in China have recently gathered in Dalian Rubber Plastic Machinery Co., Ltd. to negotiate orders for the first internal mixer with a total volume of 650 liters in China with independent intellectual property rights.

The internal mixer is an indispensable key equipment for the production of tires and the production of various rubber products. At present, the largest capacity internal mixer used by domestic rubber tire companies is 370 liters. The rubber volume of the 650-liter mixer developed and manufactured by the company is equivalent to 1.6 times the mixing volume of the 370 litre mixer. It can directly save 20% for rubber tire companies and save 15% of energy. So far, only two companies in the world can produce large-capacity mixers.

Dalian Rubber & Plastic Co., Ltd. produced the first 250 litre internal mixer in China in 1955 and has been producing mixers for more than 50 years. In the process of R&D and production of mixers, technicians combined advanced foreign technology and accumulated years of process technology to form a series of “Made in China” mixers ranging from 250 liters to 650 liters in 10 specifications.
