Injection Type Tire Capsule Curing Press

A tire curing press is a machine used in the tire manufacturing industry to cure or vulcanize the rubber compound inside a tire to achieve its final shape and properties. The curing process involves applying heat and pressure to the tire to bond the rubber compounds, reinforcing materials, and other components together, resulting in a strong and durable tire.

An injection type tire capsule curing press is a specific type of tire curing press that utilizes injection technology. It combines the functions of an injection molding machine and a curing press to produce high-quality tires.

Here's how an injection type tire capsule curing press generally works:

1. Preparing the tire capsule: A tire capsule is a hollow bladder that is used to contain the uncured tire during the curing process. It is typically made of heat-resistant rubber or elastomeric material. Before the curing process, the tire capsule is prepared by placing it inside the mold cavity of the curing press.

2. Injection molding: In this step, the rubber compound is mixed and heated to a molten state. The molten rubber is then injected into the tire capsule through injection nozzles or channels in the mold. This injection process helps to mold the rubber compound into the desired shape and distribute it evenly inside the tire capsule.

3. Curing: Once the tire capsule is filled with the molten rubber compound, the curing press applies heat and pressure to the assembly. The heat causes the rubber compound to vulcanize or cure, transforming it into a solid and stable form. The pressure applied ensures proper bonding between the rubber compound and any reinforcing materials, such as steel belts or fabric plies.

4. Cooling and demolding: After the curing process, the tire is allowed to cool down gradually to room temperature. Cooling helps to set the tire's shape and properties. Once cooled, the cured tire is then removed from the tire capsule using demolding mechanisms, such as ejector pins or hydraulic cylinders.
