A New Industry.
Seven Cylinders.
One Tire.<\/h2>\n

From forging presses to electric furnaces, from cement mills to injection moulding machines \u2014 now tire manufacturing. A vulcanizing machine (tire curing press) uses seven hydraulic cylinder types to clamp the mold, shape the rubber, cure it under heat and pressure, open the mold, remove the finished tire, and flip it for the next stage. The tipping cylinder handles the last step: rotating the freshly cured tire 180\u00b0 so it lands in the correct orientation on the post-cure conveyor.<\/p>\n

What Happens Inside a Vulcanizing Machine \u2014 And Where the Tipping Cylinder Fits<\/h2>\n

A tire starts as a “green tire” \u2014 an uncured assembly of rubber compounds, steel belts, and fabric plies built on a tire building machine. The green tire is soft, tacky, and has no tread pattern. The vulcanizing machine transforms it into a finished tire by curing it under heat (150\u2013180 \u00b0C) and pressure (15\u201325 bar) for 10\u201330 minutes inside a precision mold that imprints the tread pattern, sidewall markings, and final shape.<\/p>\n

After curing, the mold opens, the tire is lifted out (by the loading\/unloading cylinder), and then it must be flipped \u2014 rotated 180\u00b0 \u2014 before it is placed on the post-cure conveyor or post-cure inflator. The tipping cylinder performs this flip. It is the final motion in the vulcanizing cycle before the tire moves to inspection and storage. Korea Ever-Power manufactures the tipping cylinder as the first of seven vulcanizing machine hydraulic cylinders<\/a>.<\/p>\n

Fixed Specification \u2014 Why This Cylinder Has No Range<\/h2>\n
\n \"Fixed-specification<\/p>\n

Most cylinders in this catalogue are specified as ranges \u2014 bore 200\u2013700 mm, stroke \u22644,000 mm \u2014 because they serve machines of varying sizes. The tipping cylinder is different: bore 50 mm, rod 28 mm, stroke 310 mm. Fixed. One size.<\/p>\n

The reason is the flipping mechanism geometry. The tipping mechanism on a standard tire curing press is a standardized linkage \u2014 a hinged arm that grips the tire at two points and rotates it 180\u00b0. The cylinder’s connection to this linkage is at a fixed distance from the pivot, and the required arc (180\u00b0 of tire rotation) translates to exactly 310 mm of linear cylinder stroke. The force to flip a passenger car tire (8\u201315 kg at 150\u2013180 \u00b0C) through this linkage requires a 50 mm bore at the press’s system pressure.<\/p>\n

This standardization is an advantage for tire manufacturers: the tipping cylinder is a drop-in replacement part \u2014 no engineering review, no custom drawing, no lead time for bore\/stroke selection. Korea Ever-Power manufactures the tipping cylinder as a stock item for immediate delivery to vulcanizing machine builders and tire plant maintenance departments.<\/p>\n<\/p><\/div>\n

\n

Why a Freshly Cured Tire Needs to Be Flipped<\/h2>\n

The tire exits the mold in a specific orientation \u2014 typically with the upper sidewall facing up. But the next process step may require a different orientation:<\/p>\n

\n
\n Post-cure inflator (PCI) loading<\/strong><\/p>\n

Many curing presses feed the tire directly to a post-cure inflator \u2014 a device that holds the tire inflated at controlled pressure while it cools, preventing it from deforming as the rubber contracts during cooling. The PCI may require the tire in a specific orientation (lower bead down) that is opposite to the mold exit orientation. The tipping cylinder flips the tire to match the PCI loading orientation.<\/p>\n<\/p><\/div>\n

\n Conveyor orientation for inspection<\/strong><\/p>\n

The post-cure conveyor transports the tire to the inspection station, where automated cameras and laser scanners check the tread surface, sidewall markings, and overall shape. The inspection equipment may require the serial-number sidewall facing a specific direction. The tipping cylinder ensures every tire arrives at inspection in the standard orientation \u2014 regardless of which mold cavity it came from.<\/p>\n<\/p><\/div>\n

\n Stacking and palletising<\/strong><\/p>\n

Finished tires are stacked in specific orientations for warehouse storage and shipping. Some stacking patterns require alternating tire orientations (one tread-up, one tread-down) to create stable stacks. The tipping cylinder flips every other tire to create the alternating pattern automatically \u2014 without manual handling of hot, heavy tires.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

<\/p>\n

\n
\n

150\u2013180 \u00b0C and Still Pliable \u2014 Why the Flip Must Be Gentle<\/h2>\n

The tire exits the mold at vulcanizing temperature \u2014 150\u2013180 \u00b0C. At this temperature, the rubber is fully cured chemically but still mechanically softer than at room temperature. A hard impact or an abrupt stop during flipping can distort the tire \u2014 creating a flat spot, a bead deformation, or a sidewall crease that becomes a permanent defect once the rubber cools and stiffens.<\/p>\n

\n
\n Smooth acceleration at flip start<\/strong><\/p>\n

The cylinder must lift the tire off its resting surface and begin the rotation without jerking. A sudden start snaps the tire’s weight against the gripper \u2014 potentially slipping the tire in the gripper or deforming the bead area. The flow control valve ramps the cylinder speed from zero to operating speed over 0.2\u20130.5 seconds.<\/p>\n<\/p><\/div>\n

\n Cushioned deceleration at flip end<\/strong><\/p>\n

At the end of the 180\u00b0 rotation, the cylinder must decelerate the tire smoothly onto the receiving surface \u2014 not slam it down. The end-of-stroke cushion absorbs the kinetic energy of the tire’s mass and the linkage inertia, bringing the assembly to a controlled stop. This cushion is critical for every cycle \u2014 a hard landing every 10\u201330 minutes (one cure cycle) accumulates into thousands of impacts per month.

Korea Ever-Power supplies all seven cylinder types for vulcanizing machine builders \u2014 from the 50 mm bore tipping cylinder to the 220 mm bore pressurised cylinder \u2014 as a coordinated set engineered for the same press’s hydraulic system, temperature environment, and cycle time.<\/p>\n<\/section>\n

Manufacturing \u2014 Standardised for Stock Availability<\/h2>\n
\n \"Korea<\/p>\n

The fixed specification (50 mm bore, 28 mm rod, 310 mm stroke) allows Korea Ever-Power to manufacture the tipping cylinder in batches for stock rather than as custom orders. Batch production ensures dimensional consistency across units \u2014 every tipping cylinder is interchangeable with every other, which is critical for tire plants that operate dozens of identical vulcanizing presses and need identical replacement parts across all machines.<\/p>\n

The bore is honed to Ra 0.2\u20130.4 \u00b5m. The rod is chrome plated at 30\u201350 \u00b5m. Seals are FKM (Viton) rather than standard NBR \u2014 because the cylinder operates near the vulcanizing mold, where ambient temperatures reach 60\u2013100 \u00b0C from the mold’s radiant heat. Standard NBR seals would age prematurely at these temperatures; FKM provides the required heat resistance for the cylinder’s operating life.<\/p>\n

Every tipping cylinder is hydrostatic tested at 1.5\u00d7 working pressure and functionally tested for full extend-retract with cushion verification. The standardised test protocol matches the standardised specification \u2014 ensuring every unit performs identically out of the box.<\/p>\n<\/p><\/div>\n

FAQ<\/h2>\n
\n
\n

How many times per day does the tipping cylinder operate?<\/h3>\n

Once per cure cycle \u2014 typically every 10\u201330 minutes for passenger car tires, every 30\u201390 minutes for truck and bus tires. On a press running 24\/7, that is 48\u2013144 cycles per day for passenger tires. The cycle count is moderate compared to injection moulding cylinders (which cycle thousands of times per day) but still demands reliable cushion performance and consistent seal life over the annual campaign.<\/p>\n<\/p><\/div>\n

\n

Does the tipping cylinder handle truck tires too?<\/h3>\n

The standard 50 mm bore specification is designed for passenger car and light truck tires (8\u201325 kg). Heavy truck and bus tires (50\u201380 kg) and OTR (off-the-road) tires (200+ kg) require larger tipping cylinders with more force and a different linkage geometry. Korea Ever-Power engineers custom tipping cylinders for large-tire presses \u2014 with bore, rod, and stroke sized to the specific tire weight and flipping mechanism. Contact the vulcanizing cylinder team<\/a>.<\/p>\n<\/p><\/div>\n

\n

Can the tipping function be omitted if the post-cure conveyor does not require flipping?<\/h3>\n

Yes \u2014 some press layouts do not require tipping. But most modern tire plants specify the tipping function because it provides flexibility: the same press can feed different downstream equipment (PCI, conveyor, stacker) without reconfiguring the line. The tipping cylinder is a low-cost insurance policy against future layout changes. Similar application flexibility applies across the forklift attachment cylinder range<\/a> and telescopic cylinder programme<\/a>.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n
