The vulcanizing machine in the production of motorcycle inner tubes is a key piece of equipment in the manufacturing process. It is mainly used to heat and pressurize the formed raw tubes (unvulcanized rubber blanks) to make them undergo vulcanization reactions, thereby endowing the inner tubes with elasticity, strength and durability. The following is a detailed introduction to the inner tube vulcanizing machine for motorcycles:
The function of the vulcanizing machine
Vulcanization reaction: By heating (typically 140°C to 160°C) and applying pressure, the rubber molecular chains are cross-linked, enhancing the physical properties of the inner tube (such as tear resistance and aging resistance).
Shaping: Ensure that the inner tube shape is stable and meets the standard size (such as the common 17 inches, 18 inches, etc. on motorcycles).
2. Main types of vulcanizing machines
(1) Individual vulcanizing machine (single-mode vulcanizing machine)
Features: A single mold works independently, suitable for small-batch or multi-specification production.
Applicable scenarios: Small and medium-sized inner tube factories or situations where molds need to be frequently changed.
(2) Automatic vulcanizing machine (multi-mode vulcanizing machine)
Features: Multi-station design, high degree of automation (automatic mold opening, closing, and exhaust), and high efficiency.
Applicable scenarios: Large-scale production, such as a production line for motorcycle tires.
(3) Vacuum vulcanizing machine
Feature: Vacuuming is carried out before vulcanization to prevent air bubbles inside the inner tube and increase the yield of finished products.
Advantages: Suitable for the production of high-end inner tubes or Butyl inner tubes.
3. The core structure of the vulcanizing machine
Molds: They are divided into upper and lower molds, engraved with tire patterns and specification marks, and are mostly made of alloy steel.
Heating system: Electric heating or steam heating (steam is more uniform, but it needs to be matched with a boiler).
Hydraulic system: Provides clamping pressure (typically 10 to 20MPa) to ensure sealing during the vulcanization process.
Control system: PLC automatically controls temperature and pressure, and records the vulcanization time curve.
4. Key parameters of vulcanization process
Temperature: Butyl rubber is commonly used at 150°C to 160°C, while natural rubber is slightly lower.
Pressure: The pressure inside the mold needs to be stable (1.5-2.5MPa).
Time: Adjust according to thickness (usually 5 to 10 minutes for motorcycle inner tubes).
5. Example of production process
Preparation of rubber blanks: Extruded inner tube rubber blanks (including valve spouts).
Mold installation: Place the rubber blank into the preheated mold, and align the valve orifice with the positioning holes.
Vulcanization: The mold is closed, pressurized and heated. After vulcanization is completed, the mold is automatically opened.
Post-processing: Trim burrs and conduct air tightness testing.
6. Selection suggestions
Output: Single-mode is selected for small batches, and multi-mode automatic lines are chosen for large batches.
Energy: Electric heating is convenient but costly, while steam heating requires a boiler.
Mold compatibility: Supports mold replacement to adapt to different types of inner tubes (such as off-road vehicles/scooters).
7. Common Problems and Solutions
Insufficient vulcanization: Check the temperature uniformity or extend the vulcanization time.
Bubble defect: Switch to a vacuum vulcanizing machine or optimize the exhaust of the rubber compound.
Mold adhesion: Regularly clean the mold and use a mold release agent.

Inner tube process flow
Inner tubes are indispensable components on vehicles such as bicycles, motorcycles and cars. They are responsible for bearing the weight of the vehicle and withstanding the impact of the road surface. Therefore, their manufacturing process is of great significance. The following is a brief introduction to the inner tube process flow:
1. Raw material selection: The raw materials for inner tubes are usually natural rubber and synthetic rubber. Before the process flow begins, the selection and mixing of raw materials must be carried out first to ensure that the inner tube has sufficient flexibility and wear resistance.
2. Mold making: The formation of inner tubes requires the aid of molds, so the design and manufacture of molds should be based on the size and shape of the inner tubes.
3. Mixing and molding: The rubber that has been mixed with raw materials is placed in a mixer for heating and mixing, and then extruded into position through an extruder
4. Molding and vulcanization: Rubber is molded through molds, and then the molded inner tubes are placed in a vulcanizing machine for vulcanization treatment to enhance the strength and wear resistance of the rubber.
5. Inspection and Packaging: Quality inspection is carried out on the inner tubes produced to ensure they meet the standard requirements. Then, they are packaged and sent to warehouses and other places for storage and distribution.
Although the production process of inner tubes is simple, the involved process steps are very complicated. Every link needs to be strictly controlled to ensure the stable quality of the inner tubes produced. With the development of technology and the improvement of craftsmanship, the production process of inner tubes is constantly being refined and enhanced to meet people's demands for safety, comfort and durability.
