Solid tire manufacturing process

Core Materials of Solid Tires
The 'skeleton' of a solid tire is constructed from three layers of special materials:

 

Base Rubber: A composite of high-hardness natural and synthetic rubber, with added carbon black to enhance wear resistance.

 

Cushioning Layer: A microporous polyurethane interlayer that absorbs over 80% of impact energy.

 

Tread Pattern: Specially formulated rubber laser-engraved, increasing grip by 2 times.

 

Key Hot-Pressure Molding Process
The 'solid transformation' is completed in a 150℃ mold:

 

Step 1: The pre-formed rubber blank is placed in the mold, initially shaped under 10MPa pressure.

 

Step 2: Segmented heating to 180℃, allowing for full cross-linking of the rubber molecular chains.

 

Step 3: Rapid cooling with cold water, forming a uniform network structure internally.

 

Performance Enhancement
These designs make solid tires 'hard but not brittle':

 

Honeycomb Structure: Internal honeycomb-like arrangement, reducing weight by 30% while maintaining rigidity.

 

Graded Hardness: Hardness increases from the tread to the rim, balancing comfort and support.

 

Self-Cleaning Tread Pattern: V-shaped groove design automatically removes debris such as stones.
