Detailed explanation of solid tire vulcanizer
Solid tires are mainly used in low-speed and high-load scenarios such as forklifts, AGV trolleys, construction machinery, and port equipment. Their vulcanization process is different from that of pneumatic tires and requires a special vulcanizer. The following is an analysis of the core technology, equipment types, and process of solid tire vulcanizers:

1. Core functions of solid tire vulcanizers
Solid tire vulcanizers must meet the following requirements:

High-pressure vulcanization (15-25MPa) ensures that the rubber and the rim are tightly bonded.

Sectional heating (the temperature of the tread and sidewall can be independently controlled).

Quick demoulding (solid tires have no inner cavity and require special mold design).

2. Main types of solid tire vulcanizers

(1) Flat plate vulcanizer (molding type)
Applicable products: small and medium-sized solid tires (such as forklift tires, AGV tires).

Working principle:

Put the preformed rubber into the mold and pressurize and heat the upper and lower plates (temperature 150-180℃).

Vulcanization time is adjusted according to thickness (usually 30-90 minutes).

Advantages: low investment, suitable for small-batch production of multiple specifications.

(2) Injection vulcanizer
Applicable products: high-precision solid tires (such as medical equipment wheels, precision industrial tires).

Working principle:

The rubber is filled into the mold through screw injection and vulcanized under high pressure.

Advantages: no bubbles, high rubber utilization rate, but high equipment cost.

(3) Automatic flip vulcanizer
Applicable products: large solid tires (such as port machinery tires, mining tires).

Features:

The mold can be flipped 180° for easy demoulding.

Integrated hydraulic ejector device to reduce manual labor intensity.

(4) Continuous vulcanization production line (for pre-vulcanized tread)
Applicable process: Some solid tires use pre-vulcanized tread + secondary vulcanization process to improve efficiency.

Technical parameters

5. Suggestions for selecting solid tire vulcanizing machines
Small tires (diameter <500mm) → flat vulcanizing machine (500-1000 tons).

Medium-sized tire (diameter 500-1000mm) → flip-type vulcanizing machine (with automatic top die).

Large tires (diameter >1m) → Customized hydraulic vulcanizing machine (segmented heating control).

High-precision tire → injection vulcanizing machine (suitable for PU or special rubber).
