Vacuum Rubber Curing Press Machine_Rubber Press Machine

A vacuum rubber curing press machine, also known as a vacuum rubber vulcanizing press machine, is a specialized equipment used in the rubber industry for curing or vulcanizing rubber products under vacuum conditions.

It is designed to enhance the quality and performance of rubber products by ensuring uniformity in the curing process.

The machine typically consists of a hydraulic system, heating plates, a vacuum chamber, and a control panel. The hydraulic system applies pressure to the rubber material, while the heating plates provide the necessary heat

for curing. The vacuum chamber is used to create a vacuum environment by removing air and gases, allowing for more effective curing of the rubber.

The vacuum curing process helps to eliminate air bubbles and improve the overall quality of the rubber product. It enhances the bonding of rubber compounds, reduces porosity, and increases the strength, durability,

and uniformity of the cured rubber.

Vacuum rubber curing press machines are commonly used in the production of various rubber products, including rubber seals, gaskets, tires, hoses, and other rubber components. The specific design and specifications of

the machine may vary depending on the manufacturer and the requirements of the application.

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 dustproof 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.
