High Quality Double Layer Inner Tube Curing Machine For Motorcycle And Bicycle Inner Tube Production Line

Product Examples

• LLN-25/2 Double-Layer Hydraulic Tube Curing Press: It is suitable for curing various bicycle and motorcycle inner tubes. Except for the manual operation of loading and unloading the inner tubes, the entire curing process is automatically controlled. It has a maximum mold clamping force of 255 kN, a heating plate with a maximum outer diameter of 760 mm, and can adapt to molds with a height of 70-120 mm.
• Motorbike Two Layer Inner Tyre Tube Vulcanizing Machine with Hydraulic Pressure Station: It is of Chinese origin, with the brand "Running" and certifications like CE, ISO, and SGS. It is available in the model number 6-19 inch. It uses a multi-network structure, and multiple vulcanizing presses share a hydraulic pressure station. Each machine can operate independently without affecting the work of other units.

Structure and Principle

• Structural Components2: Usually includes a base, a "П"-shaped frame mechanism, a hydraulic lifting mechanism, a curve guiding mechanism, and an automatic control box. The base is fixed on the ground, and the hydraulic lifting mechanism is installed in its installation cavity, connecting the lower mold plate of the frame mechanism. The curve guiding mechanism is set between the left and right support arms of the "П"-shaped frame mechanism and is hinged to the mold plate. The automatic control box is on the outside of the support arm, connecting the hydraulic circuit to the oil cylinder of the hydraulic lifting mechanism and the air circuit to the mold on the mold plate of the "П"-shaped frame mechanism.
• Working Principle: First, the pre-inflated and shaped inner tube is placed into the mold5. Then, steam is input into the jacket of the upper and lower tire molds respectively for continuous heating according to different curing conditions and time requirements. The machine completes operations such as mold closing, inner pressure steam filling, steam exhaust, and mold opening automatically or manually. Finally, the cured inner tube is taken out.

Advantages over Single-Layer Machines

• Higher Production Efficiency: As it cures two layers of inner tubes at a time, the production output is theoretically doubled compared to single-layer curing machines, improving production capacity.
• More Uniform Curing: The double-layer structure can make the heat transfer and pressure distribution more uniform, reducing the occurrence of partial vulcanization and improving the quality stability of the inner tube.

Considerations When Choosing

• Production Capacity: It should match the production scale of the enterprise. If the production volume is large, a machine with higher production efficiency and larger mold clamping force is required.
• Accuracy and Stability: High-precision equipment can ensure the dimensional accuracy and physical properties of the inner tube, while stable performance reduces equipment failures and maintenance costs.
• Energy Consumption: Energy-saving equipment can reduce production costs. It is necessary to compare the energy consumption of different models under the same production conditions.

Additional Notes

1. Customization: Many manufacturers offer customizable options for mold sizes, heating systems, and automation levels to suit specific production needs.

2. Cycle Time: The curing time depends on the rubber compound, tube thickness, and curing temperature.

3. Energy Source: The choice of heating system (electric, steam, or hot oil) depends on the availability and cost of energy in your facility.

4. Production Capacity: The number of tubes produced per shift can vary based on the machine's efficiency, operator skill, and workflow.
