Tyre Retreading Precured Tread Rubber and Tread Rubber Compound

tyre retreading precured tread rubber and tread rubber compound

Precured tread rubber is a specialized component used in the tyre retreading process.  Tyre Retreading is a sustainable practice that involves replacing the worn-out tread of a tire with a new layer of tread, extending the life of the tire and reducing overall waste.  Precured tread rubber plays a crucial role in this process.

Precured tread rubber is made by applying a layer of pre-vulcanized rubber onto a fabric or steel belt.  This layer has a predetermined tread pattern and is cured (vulcanized) before being applied to the tire casing.  The precuring process ensures that the tread is already vulcanized and ready for use, making it more efficient and cost-effective in the tyre retreading process.

We produce different pattern and different size tread rubber and cushion gum according to customer's needs for truck and OTR tyres.

A tire retreading machine is a specialized piece of equipment used in the process of retreading tires.
Retreading is a cost-effective and environmentally friendly alternative to buying new tires, as it involves replacing the worn-out tread of a tire with a new one.Here is some information about tire retreading machines:

1.Purpose:Tire retreading machines are designed to remove the old tread from a tire and apply a new tread. This process helps to extend the life of a tire, reduce waste, and save money.

2.Types of Machines: There are different types of tire retreading machines available, including:
Tyre Buffing Machines: These machines are used to remove the old tread from the tire.They use abrasive tools to buff the surface of the tire, preparing it for the application of a new tread.

Tyre Building Machines: Building machines are used to apply the new tread onto the tire. They use specialized tools and techniques to ensure a precise and secure application.


Curing Chamber Machines: Curing machines are used to heat and press the tire, allowing the new tread to bond with the tire's surface. This process ensures a strong and durable connection.
Envelope changer: It is mainly used for assembly and disassembly of envelope in the pre-vulcanized tire recapping processes. This machine could effective relieve the labor intensity required for the assembly and disassembly of envelope and save the labor force and time and improve the working efficiency.


Rubber cement mixer: It is used to prepare the rubber cement used for rubber lamination of rubber products. This machine is reasonable in structure, simple in operations and reliable in safety and long in service life.



The screw type rubber extruder: is necessary for tire recapping process. This machine features stable running, proper extruding speed and proper temperature and simple operation and good durability etc.


Multifunctional tire repair machine: It is special equipment used in prevulvanizing recapping process. This machine could realize a series of functions including inspection, grinding, rubber cement brushing, and application of intermediate adhesive in the recapping process, which could be operated simply and conveniently and lower labor intensity of workers and improve the working efficiency. 


The steel ring changer: It is used for assembly and disassembly of steel rings in the pre-vulcanizing tire recapping process. In order to facilitate the operations, it is usually used together with envelope changer. It is fixed at the back or side of envelope changer.


3.Process: The process of tire retreading involves several steps:
Inspection: The tire is thoroughly inspected to determine if it is suitable for retreading.Any damage or defects are identified and repaired.
Buffing: The old tread is removed using a buffing machine. This step prepares the tire for the application of a new tread. Building: The new tread is applied to the tire using a building machine. The tread is carefully selected based on the specific requirements of the tire.
Curing: The tire is placed in a curing chamber machine, where it is heated and pressed. This step ensures that the new tread bonds securely with the tire's surface.

4.Benefits: Tire retreading offers several benefits, including: Cost Savings: Retreaded tires are significantly cheaper than new tires, making them a cost-effective option for businesses and individuals.

Environmental Impact: Retreading tires reduces the demand for new tires, which helps to conserve natural resources and reduce waste.
Performance:Retreaded tires can offer similar performance to new tires, especially when they are properly maintained and used in appropriate conditions. In conclusion, tire retreading machines play a crucial role in the process of retreading tires. They help to extend the life of tires, reduce waste, and provide a cost-effective alternative to buying new tires.
