Hydraulic vulcanizing press for manufacturing truck retread tire
tread
The retread tread pre-vulcanizer is a device specially used for
pre-vulcanizing the tread during the retreading process. The
retread pre-vulcanization is to peel off the worn tread of the old
tire, vulcanize the new tread rubber through the pre-vulcanizer,
and then adhere it to the old tire body, so as to extend the
service life of the tire.
Main components of the retread tread pre-vulcanizer
Heating system: usually electric heating or steam heating is used to ensure that
the rubber material reaches the predetermined vulcanization
temperature.
Mold: used to mold the tread, the design of the mold directly affects
the pattern and performance of the tread.
Pressure system: using hydraulic or mechanical pressure system to ensure that the
tread material is subjected to uniform pressure during the
vulcanization process.
Control system: including temperature, pressure and time control to ensure that
each tread can achieve consistent vulcanization quality.
Advantages of retread tread pre-vulcanization
Cost saving: through the retreading process, old tires can be reused, greatly
reducing the overall cost of tire use.
Environmental protection: reducing the discarding of waste tires is conducive to
environmental protection.
Improve tire performance: Pre-vulcanized tread rubber materials have higher wear resistance
and adhesion, making the performance of retreaded tires close to
that of new tires.
Process flow of pre-vulcanization of retreaded treads
Old tire inspection: Check whether the old tire body is suitable for retreading and
remove unqualified tire bodies.
Tread stripping: Peel off the worn part of the old tread.
Surface treatment: Treat the surface of the tire body to enhance the adhesion of the
new tread.
Tread pre-vulcanization: Use a pre-vulcanizer to vulcanize the new tread rubber.
Adhere to the new tread: Adhere the pre-vulcanized tread to the treated tire body.
Final vulcanization: Perform final vulcanization on the adhered tire to ensure a firm
bond between the tread and the tire body.
Precautions for use
Equipment maintenance: Regularly check and maintain the equipment to ensure the normal
operation of the heating system, pressure system, etc.
Temperature control: Strictly control the vulcanization temperature to avoid excessive
or low influence on the tread quality.
Safe operation: High temperature and high pressure equipment must
be operated in strict accordance with the operating procedures to
prevent accidents.
The retread tread pre-vulcanizer plays an important role in the
tire retreading industry. Through reasonable use and maintenance,
it can greatly improve the quality and service life of retreaded
tires, reduce production costs, and contribute to environmental
protection.
