Recently, Guilin Rubber Machinery (GRM) has upgraded two all-steel giant tire molding machines respectively with models of 49"-51" and 57"-63". The newly upgraded machines have been applied with 33 national patent technologies, including 15 invention patents, ensuring high efficiency and precise control and enhancing the quality and stability of tires. Through the customer’s on-site inspection, they have met the new technology requirements and strict safety standards. They have been successfully delivered to the customer.
The upgraded 49"-51" all-steel giant tire molding machine is “in service” at the customer’s site
The molding machine represents the core equipment for tire manufacturing. The two molding machines are tailored for manufacturers to make giant engineering tires of 49", 51", 57" and 63". They have been in good use since they were put into service at customers’ plants in 2018. For this upgrading, GRM’s technical team has focused more efforts on the quality of tires to improve the performance of production equipment as a way to meet the demand of customers for high-quality giant tires. Through more than a year of technical research, the team has achieved automatic blowing and floating of tire carcass steel cord ply compound and automatic centering and laminating of steel cord ply, significantly improving the laminating efficiency and guaranteeing its quality. It has innovated the structure of two-axis connecting device, with more uniform force in the tire molding. It has designed a new mechanical forward and reverse package device and increased the positioning sleeve to significantly reduce the wear and deformation of parts, which strongly guarantees the equipment precision. In addition, the technical team has also upgraded the automation and operating efficiency of equipment.
GRM produced and sold its first one-stage three-drum molding machine for all-steel truck radial tires in 2006 and developed 51" all-steel radial giant tire molding machine in 2007 and 40R57 all-steel giant tire molding machine in 2009. Specifically, 51" all-steel radial giant tire molding machine was included in the national science and technology support program, winning the first prize of Guangxi Science and Technology Progress Award in 2009. GRM has made an important contribution to its independent production of all-steel radial giant engineering tires for China’s tire manufacturers and the removal of international trade barriers. In 2017, the drum-type ply tube molding machine for engineering tires went global for the first time, with Made in China recognized by overseas customers.
Currently, GRM has been capable of designing and producing a full range of LCZ all-steel giant tire molding machine, a series of LCG bias engineering tire molding machine, two-stage molding machine for all-steel truck radial tires, agricultural radial tire molding machine and other molding machines, with rich experiences in providing tire molding solutions for manufacturers.
