EVA foaming vulcanization machine is a mechanical equipment specialized in producing foaming products of materials such as EVA (ethylene vinyl acetate copolymer), PE (polyethylene), PVC (polyvinyl chloride), 

SBR (styrene butadiene copolymer), etc. These types of machines are widely used in the manufacturing of shoe materials, floor mats, sports protective materials, beach soles, insulation materials, and other fields. 

Its main features and functions include:

1. * * Automatic Control and Exhaust * *: Modern EVA foaming vulcanization machines are usually equipped with an automatic control system, which can accurately control parameters such as temperature, pressure, 

and time during the foaming process. At the same time, it has an automatic exhaust function, which helps to improve the quality of the finished product and ensure that the produced foaming material is uniform and 

free of bubbles.

2. * * High Performance and Stability * *: Equipment design focuses on performance stability, ensuring reliability during continuous production processes, reducing failure rates, and improving production efficiency.

3. * * Wide range of applicable materials * *: Suitable for foaming treatment of various materials, meeting the needs of different industries, such as EVA, PE, PVC, SBR, etc., with strong adaptability.

4. Customized Services: Our factory can provide customized processing services to customize equipment models, specifications, and special functions according to the specific needs of customers.

5. Heating and temperature control: Using hydraulic or electric heating methods, combined with a mold temperature machine, can ensure uniform temperature of the heating plate, which is crucial for foam quality. 

Uneven temperature may cause problems such as loose bonding of product joints, so equipment is usually equipped with functions to detect and adjust the temperature of the heating plate.

6. * * Non standard and PLC Control * *: Some devices offer non-standard designs and use PLC (Programmable Logic Controller) for higher-level automation control, making the production process more flexible and efficient.

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.

Good parts ensures good machine quality, but it need plus a good design.
