A few days ago, the first “ one-step legal rubber production line” independently designed, developed and produced by Qingdao Double Star Group was officially put into operation at Double Star Dongfeng Tire Company. The rubber refining process is a key process for tire manufacturing and directly determines the quality and cost of the tire. In the past, Lianpeng always used traditional old techniques, old techniques, and old processes, which resulted in low production efficiency, large investment in equipment, high labor intensity, and complicated production processes. Double Star Dongfeng Tire Co., Ltd. has broken through the technical exclusion zone of “traditional refining technology must be divided and mixed” through hundreds of technical optimizations and equipment transformations, and realized the transformation of the rubber refining process from the past four times to one-time completion, creating The “one-time-advanced rubber compounding technology” featuring dual-star features has achieved one-stop production of tires from raw material input to extrusion extrusion.

The putting into operation of the “one-time legal rubber production line” has improved production efficiency, reduced production costs, and reduced labor intensity. It has also achieved outstanding results in terms of reduction of staff, quality of energy materials, and harmful gas emissions. Benefits of nearly 10 million yuan. After testing, the performance of the tires produced by the “one-step blending rubber production line” has been significantly improved, in which the tread wear resistance has been improved by 10-15% and the quality stability has been improved by more than 20%. The operation of the “One-Stage Lacquer Production Line” is a major contribution to the development of the national tire industry by Double Star Tire, which symbolizes that the Twin Star Tire with its own responsibility for the development of national brands has once again achieved a new level of core technology and characteristic technology. Breakthrough and leapfrogging.
