Tube Curing Press
Direct-curing vulcanizing presses for inner tube production — six frame sizes covering bicycle, motorcycle, passenger car and truck tube moulds.
The Tube Curing Press vulcanizes extruded and spliced rubber tube into its finished form. Upper and lower heated platens close onto the mould under hydraulic pressure, holding temperature and pressure through the cure cycle to give the tube its final strength and elasticity.
Six frame sizes are available, selected by the mould the tube requires — from the smallest bicycle tubes up to 16.00-30 truck moulds. Presses are built to order, and platen configuration can be adapted to the customer’s mould and layout.
| Process | Direct curing (vulcanizing) of inner tube |
| Frame sizes | 6 — NO.L1 / NO.1 / NO.2 / NO.3 / NO.5 / NO.6 |
| Mould range | Bicycle ID 2.00-4 up to truck 16.00-30 (inch) |
| Mould actuation | Two-stage open / close speed |
| Platen structure | Internal Junction Structure, optional |
| Build | Made to customer requirement |
Select the frame by the mould.
| Model | Applicable mould specification | Typical application |
|---|---|---|
| NO.L1 | 8.25-20 ~ 16.00-30 (inch) | Truck / heavy duty |
| NO.1 | 7.50-15 ~ 12.00-20 (inch) | Truck / light truck |
| NO.2 | 6.00-13 ~ 8.25-16 (inch) | Light truck / passenger car |
| NO.3 | 6.00-13 ~ 6.50-14 (inch); bicycle ≥20″; motorcycle | Passenger car / motorcycle / bicycle |
| NO.5 | ID 6.00-12 (inch); bicycle 20″–24″ | Bicycle / motorcycle |
| NO.6 | ID 2.00-4 ~ 5.00-12 (inch); bicycle ≤20″ | Bicycle, small wheel |
Mould specification is the selection criterion. If your mould falls between two frames, or you are working to a mould we have not listed, send us the drawing and we will confirm the frame.
Built for multi-press tube curing lines.
Four of the six frames.
Key Features
- Two-stage mould speed — the mould approaches fast, then closes slow. It does not slam. Mould life is extended and the cured tube is more consistent. (NO.1, NO.2, NO.3, NO.5, NO.6)
- Internal Junction Structure — a platen design available with or without, specified to suit the customer’s tooling. (NO.1, NO.2, NO.3, NO.5, NO.6)
- Silicone O-ring sealing — a patented seal design that extends the replacement interval and lowers long-term consumable cost. (NO.L1)
- FC 35 cast machine body — cast iron frame, chosen for rigidity and long service life under continuous production. (NO.L1)
- Uniform heating — upper and lower platens heat evenly across the mould face.
- Made to order — the press is built around the mould and the line, not the other way round.
Benefits
- Longer mould life — controlled closing removes the impact that shortens tooling life
- Consistent cure — even platen heat and held pressure give repeatable tube quality
- Lower running cost — durable seals and a cast frame reduce downtime and consumable spend
- Full size coverage — one supplier across bicycle, motorcycle, passenger car and truck tubes
The Tube Curing Press is the curing stage of the inner tube line. It follows extrusion, splicing and valve insertion — see the full inner tube production sequence.
