Rubber Vulcanizing Machine
The rubber vulcanizing machine also called hot heating vulcanizing machine, rubber compression molding machine, rubber molding machine, hot pad press, or rubber vulcanizer is a traditional and old method of making rubber parts in the world, and also the most economic way to make rubber products. The rubber vulcanizing machine is a machine for vulcanizing various rubber and plastic products. It has functions such as timing clamping, automatic pressure replenishment, automatic temperature control, automatic timing, and alarm when the time comes. The vulcanizing machine is divided into three forms: electric heating, steam heating, and heat conduction oil heating. Want to know more machine details?

Rubber vulcanization is a process from raw rubber to cooked rubber. In this process, it is necessary to provide pressure, and temperature, and control the vulcanization time. The vulcanizing machine satisfies this process, the frame and hydraulic plate provide pressure, and the electric control box and heating plate provide temperature and control the vulcanization time. Regarding vulcanized raw rubber, it is a clay-like plastic body, which contains a certain proportion of sulfur. It becomes elastic rubber through a chemical reaction under a certain temperature and pressure for a period of time by heating and pressurizing. In this process, sulfur acts as a bridge between rubber molecules and molecules, so the process of rubber becoming ripe is called vulcanization. Vulcanization time refers to a period of time for maintaining the vulcanization temperature to fully vulcanize the tape, also known as holding time.
The Following are the Main Processes:
conching: Put the rubber granulates and stain into the stirring barrel to stir, and then put them into the adhesive to stir, this process requires 46 minutes ( because the adhesive is easy to cure, so stir it when used).
Weighing raw materials: weight of the rubber granulates stirred, according to the granulates’ thickness requirement of the tiles.
Paving and pressing: Paving the rubber granulates weighted on the mold, then floating it by trowel. Firstly paving the surface rubber granulates which is refined and color, then the thickness and black.
Vulcanization molding: Covering anti-adhesion cloth, and pushing the mold into the vulcanizer to vulcanize, the time of vulcanization according to the thickness of the rubber tiles, in general, 38inutes finished. After that, the mold is separate automatic, then remove floor tile on the shelves is to dry.
Inspecting: Inspect the surface of the floor tiles’ formality, no aberration, no flaw, and line with the product quality.
In special new-type rail mold openings, the mold opening angle can reach 90 degrees, which is convenient for personnel to operate. When changing the mold, it can be easily completed without removing the rail mold opening seat.
It adopts dual power, dual oil pumps, dual motors, and dual coolers, and the two shafts work completely independently.
The special design of the oil circuit system, no vibration, good stability, fast in and out of the mold, rising and falling.
The vacuum is high, and the average pumping method is used to stabilize the product and improve the quality and production capacity.
Vacuum gas storage tank base type, large gas storage space.
The new mold lifting mechanical design has a long service life, and the mold entry and exit are quiet, fast, and stable.
It is suitable for the application of precision silicone rubber products such as buttons, O-rings, and tights.
