Semi-automatic Electric Heating Hydraulic Four-layer Motorcycle Tyre Curing Press
machine
This is a highly specialized piece of equipment used in the manufacturing and retreading of motorcycle tires.
Overall Description
This is a Tire Curing Press or Vulcanizing Press. Its primary function is to transform a soft, uncured rubber "green tire" into a strong, durable, and finished motorcycle tire by applying heat and pressure in a precise mold. The process is called vulcanization.
Breakdown of Key Terms:
1. Motorcycle Tyre Curing Press
Curing/Vulcanization: This is the core process. It involves heating the raw rubber compound (with its fabric or steel cords) under high pressure inside a metal mold. This cross-links the polymer chains in the rubber, turning it from a pliable material into a resilient, elastic, and long-lasting tire.
Motorcycle Tyre: The machine is specifically designed for the smaller size and different shapes of motorcycle tires (from scooter tires to large cruiser tires), as opposed to larger presses for car or truck tires.
2. Four-Layer
This refers to the machine's physical structure and capacity.
It means the press has four independent curing stations stacked vertically on a single frame.
Advantage: This is a major space-saving and efficiency feature. One machine can cure four tires in the same cycle time it would take a single-layer machine to cure one, while occupying a much smaller footprint than four separate machines.
3. Hydraulic
This describes the power system used to generate the massive clamping force required.
A hydraulic pump and cylinder system create the pressure needed to:
Clamp the two halves of the mold tightly shut.
Force the rubber to fill every detail of the mold (creating the tread pattern and sidewall lettering).
Maintain internal pressure against the expanding steam/air inside the tire during curing.
Advantage: Hydraulic systems provide extremely high, controllable, and consistent force.
4. Electric Heating
This describes the heating method.
Instead of using steam (common in older or very large presses), this machine uses electric heating elements (like large cartridges) embedded in the mold platens (the metal plates that hold the mold).
Advantages:
Precise Temperature Control: Allows for highly accurate and even heating, which is critical for tire quality.
Energy Efficiency: No need for a separate steam boiler, reducing energy consumption and infrastructure.
Cleanliness: No condensate or steam leaks.
5. Semi-Automatic
This describes the level of operator involvement.
What the Operator Does (Manual Part):
Loads the uncured "green tire" into the open mold.
May place the curing bladder inside the tire.
Unloads the finished, cured tire after the cycle is complete.
What the Machine Does Automatically:
Once the operator initiates the cycle (e.g., by pressing a button), the machine automatically:
Closes the mold.
Applies hydraulic pressure.
Activates the heating and controls the temperature for a pre-set time.
Injects a medium (like steam or hot water) into a bladder inside the tire to apply internal pressure and heat.
Cools the tire (if programmed).
Releases the pressure and opens the mold at the end of the cycle.
Technical Parameter
| CURING TIRE SIZE | 8"-18" |
| GREEN TIRE MAX HEIGHT | 155-300 |
| MOULD MAX DIAMETER | Φ750 |
| POWER | 15-18KW |
| MAX DISTANCE BETWEEN HOU PLATE | 690 |
| BALDDER PRESSURE(kgf/cm2) | 18-20 |
Typical Workflow:
1.Preparation: The operator prepares the "green tire" and ensures the mold is clean.
2.Loading: The operator places the green tire into the bottom half of the open mold.
3.Cycle Start: The operator presses the start button for that specific layer.
Curing Cycle (Automatic):
The press closes with high hydraulic force.
An internal rubber bladder inflates inside the tire with steam or hot water, pressing the rubber against the hot mold walls.
The electric heaters maintain a precise mold temperature (e.g., 150-180°C) for a set time (e.g., 5-15 minutes, depending on tire size and compound).
1.Cycle End: The machine deflates the bladder, releases the hydraulic pressure, and opens the mold.
2.Unloading: The operator removes the finished, vulcanized tire and trims any excess rubber (flash).
Summary of Advantages:
3.High Productivity: Four-layer design allows multiple tires to be cured simultaneously.
4.Space Efficient: Compact footprint compared to multiple single-station machines.
5.Consistent Quality: Precise electric heating and hydraulic pressure ensure every tire is cured identically.
6.Operator-Friendly: Semi-automatic operation reduces physical strain and human error compared to fully manual presses.
7.Cost-Effective: Balances the high output of automation with the lower initial cost of requiring one operator for multiple stations.
This type of machine is a common workhorse in small to medium-sized tire manufacturing and professional retreading shops for the motorcycle industry.
