Semi Steel Radial R18 Tire Curing Bladder (PCR)

Key points for the design, manufacturing, and use of curing bladders for radial tires

Tire vulcanization is the main and final process in tire production. No matter how perfect all the previous processes are, if there is a problem with the vulcanization process, it can only be a complete waste and a defective product. Due to structural reasons and limited stretch, radial tires have a lower qualification rate for vulcanization. According to statistics, defects caused by vulcanization account for 60% of the total defects, while defective products caused by curing bladders account for over 30% of vulcanization defects; At the same time, it also affects the uniformity, dynamic balance, and even safety performance such as high-speed and durability of radial tires. The following mainly discusses the design, manufacturing, and usage elements of curing bladders for radial tires.
