Introduction to the functions of rubber flat vulcanization machine:
1. The rubber flat vulcanization machine of Qingdao Steady Machinery has an automatic pressure compensation function.
During the pressing process of rubber products, the pressure drop caused by the flow of raw materials can be automatically compensated.
2. The automatic exhaust time, exhaust frequency, secondary exhaust, upper and lower residence time during the exhaust process, heating temperature, vulcanization time, and mold closing pressure can all be set,
making operation convenient. Sulfurization countdown display function, vulcanization end early alarm function, and automatic mold opening.
3. Quick opening and closing of the mold, high production efficiency, slow locking and pressurization to protect the mold.
4. When the product is formed, in the vulcanizing process the oil pump motor stops working, saving electricity.
5. Adopting electric heating tubes, the temperature control accuracy of the hot plate is high.
6. Reasonable oil circuit configuration, energy-saving, and the use of high quality valves for safer and more reliable use.
7. The rubber flat vulcanization machine is designed reasonably, easy to operate and maintain.
8. Single layer, double layer or multiple layers available for selection.

Control Panel
we design different type control panel according to machine needs or customers' requirements, here just put a few for your reference.
Control Box
Mainly there are two kinds of electronics for choice. 1. China domestic made: CHNT or Delixi
2. imported international famous brand: Siemens, Schneider, Omron, Abb, etc.
Oil Cylinder and Piston of my company's rubber vulcanizing press machine:
Oil cylinder adopts QT500-7 ductile iron, called FCD50 in Japan, and for some huge size machines, we adopt cast steel oil cylinder;
piston adopts chilled hard alloy cast iron; seal adopt imported international quality sealing ring and dust proof ring, to ensure long working life.
Main parts of our rubber vulcanizing press machine, all adopts casted ductile iron or cast steel, which has good stability, don't deformation.
The piston of our rubber vulcanizing press machine adopts cold/chilled hard cast iron
1、Basic knowledge of cold hard cast iron
Cold hard cast iron is a casting alloy material that is based on elements such as iron, carbon, and silicon. By adding alloying elements such as chromium, molybdenum, and vanadium, and through casting and heat treatment processes, it achieves excellent hardness and wear resistance. Its hardness and wear resistance far exceed those of ordinary cast iron and gray iron, and it also has high strength and toughness, which has been widely used in the industrial field.
2、 The Hardness Characteristics of Cold Hardened Cast Iron
The hardness of cold hard cast iron is mainly achieved through heat treatment and chemical composition control. Compared to other casting materials, its hardness is extremely high, usually between 60-65 HRC, while the hardness of steel is only between 50-55 HRC.
3、 The manufacturing process of cold hard cast iron
The manufacturing process of cold hard cast iron mainly includes two processes: casting and heat treatment. During the casting process, control the chemical composition ratio in the as cast state to ensure the ratio of ferrite and pearlite; During the heat treatment process, magnesium spheroidization is subjected to high-temperature treatment, followed by quenching and tempering to obtain excellent hardness and toughness.
4、 The Application Prospects of Cold Hardened Cast Iron
Due to its excellent properties such as hardness and wear resistance, cold cast iron is widely used in manufacturing mechanical parts and tools under high load and high wear working environments. In the field of engineering machinery, some key components have also begun to use cold cast iron materials to improve the service life and safety performance of machinery.
Valves
Qingdao Steady Machinery Co.,Ltd. adopts international famous brand solenoid valves for it's rubber vulcanizing press machine.
Which works accurately and has a long service life.
Motor
We adopts China famous brand motor or imported brand motor if customers' have special demand.
The brand of motor we choose uses high-quality copper wire for coils and wiring, which has excellent conductivity.
Copper wire motors have good conductivity, low resistivity, and can achieve larger output power at smaller currents, thereby reducing electrical energy loss. Good corrosion resistance.
Copper wire motors are less prone to rusting and have a longer service life.
Excellent reliability. The connection points and joints of copper wire motors are easy to solder and connect, thus having higher reliability.
More durable.
The durability of copper wire motors is better than that of aluminum wire motors, because aluminum wire has a higher resistance than copper wire and generates higher heat during use, which can easily burn out the motor.
More energy-efficient, copper wire motors have a smaller resistance and lower heat generation, making them more energy-efficient.
More silent, copper wire motors used in our rubber vulcanizing press machine have less noise because aluminum wire motors have a noise level approximately 7 decibels higher than copper wire motors.
Good parts ensures good machine quality, but it need plus a good design.
Our engineer service team provide in time design according to customers work needs or special requirements:
Various kinds rubber products can be made by rubber vulcanizing press machine
