Customized Fully Automatic Vulcanizing Machine Hydraulic System Telescopic Multi-Stage Cylinder Good Hydraulic Cylinders – We Make Sure Inside Parts The tube follows GUOYUE CD250 style.
Tube steel can be 45#, 42CrMo, or 27SiMn.
Hole is ground to H8 and feels smooth, Ra under 0.4 μm.
Head, base, ears, and piston are only 45# steel.
We do not use cast iron or cast steel. Slow-Down Parts
You can pick fixed bumpers or floating bumpers so the rod slows down safe at any speed or load. Welds
We hit every heavy-load weld with ultrasound.
This takes away most of the stress and makes the weld last longer. Seals
We only use top seals from NOK (Japan), Trelleborg (Sweden), Merkel and GP (Germany).
We do not use local seals. Checks
Each cylinder is tested to GB/T15622-2005 and our own Q/GAKY014-2023.
You get a test sheet and a pass paper. Promise
We give one year cover from ship date.
If it breaks because of how we made it, we fix or swap it for free.
This cylinder is strong. It uses thick steel and hard rod. It does not bend. The seal keeps oil in, no leak. It has many tubes that slide out one by one. It lifts high but stays short
Advantages: She’s the gentle giant who knows how to reach far without taking up much space. Custom-built for your fully automatic vulcanizing machine, this telescopic multi-stage hydraulic cylinder unfolds like a magician’s wand, giving you the long stroke you need while folding back into a compact form. Each stage extends smoothly, like a slow, steady breath, ensuring precision and control. Chrome-plated rods and high-quality seals mean she stands up to the heat and pressure of vulcanizing, whispering, “I’ve got this,” every time she lifts or presses
Application Scenarios: Picture a rubber factory at dawn: this cylinder powers the vulcanizing press, opening and closing the mold with perfect precision, turning raw rubber into tough, durable tires. Or in a manufacturing plant where she helps position heavy steel plates into the vulcanizing machine, ensuring every part is perfectly cured. From tire production to industrial rubber goods, she’s the quiet heartbeat that keeps the process running smoothly, turning raw materials into finished products with grace and reliability
