How to make rubber tire bladder?
When it comes to manufacturing rubber tire bladders, precision, efficiency, stability and energy saving are the key concerns.
Hengyang Huayi Rubber Machinery — a trusted leader in the industry — stands at the forefront of innovation, providing advanced equipment and turnkey solutions for high-quality rubber bladder production.
In this article, we’ll introduce how rubber tire bladders are made and our core advantages.
1. Material Preparation
Prepare the rubber compound — including natural rubber, additives, and other ingredients — and mix them thoroughly in the mixing mill.
After mixing, the compound is cut, weighed, and preheated for injection.
⚠️ Always check the shelf life of raw materials to ensure no aged or expired compound is used before molding.
2.Injection Process
At this stage, Huayi’s high-precision rubber injection molding machines come into play. Using First-In-First-Out (FIFO) injection technology, the preheated rubber is injected into the bladder mold cavity at controlled pressure and temperature.
Servo-driven injection system ensures accuracy within ±0.5%.
SIEMENS or B&R PLC control provides intelligent and responsive operation.
Energy-saving servo system reduces power consumption by 30–70%.
Rexroth hydraulic valves ensure smooth, stable, and repeatable pressure control.
The mold is heated evenly, allowing the rubber to vulcanize under consistent temperature and pressure. Once cured, the bladder is de-molded, cooled, and inspected for quality.
