Semi-steel A- type curing bladder is a key component for curing and shaping of semi-steel radial tires in the tire curing process.

1. basic concepts
The vulcanizing bladder is a hollow thin-walled rubber product of the tire vulcanizer, which is used to be filled into the inner cavity of the tire blank to be vulcanized, and then a heating medium is introduced to cooperate with the vulcanizer for shaping and vulcanizing operations. Semi-steel type A curing bladder refers specifically to a specific type of bladder used in the curing process of semi-steel radial tires.

2. function and role
Shape retention: During the vulcanization process, the semi-steel A- type vulcanization bladder plays a supporting role to ensure that the tire maintains the correct shape and size.
Vulcanization medium: The heating medium in the bladder is used as a vulcanization medium to promote the vulcanization reaction of the tire material by heating and pressurizing to achieve the expected physical and chemical properties.
Improve quality: The use of semi-steel A- type vulcanization bladder can significantly improve the vulcanization quality and consistency of tires, and enhance the wear resistance, impact resistance and service life of tires.
