EPDM Rubber Seal Strip Production Line

Automatic EPDM Rubber Seal Strip Production Line Produces High Quality Rubber Seals Of Different Sizes

Product details:

The rubber seal strip extrusion line manufactured by Qingdao Beishun Environmental Protection Technology Co., Ltd. is a kind of equipment specially used for producing rubber seal strips. It processes rubber materials into seal strips of various shapes and sizes through extrusion molding process. The following is some key information about the rubber seal strip extrusion line:

 

main component
1. Extruder: Depending on the output and rubber characteristics, screw diameters of 65mm, 75mm, 90mm, and 120mm can be used to heat, plasticize and extrude rubber materials.

2. Mold: Installed on the head of the extruder. The size of the head can be customized according to the customer's product and used to shape the specific shape of the rubber sealing strip.

3. High-temperature shaping system: After the special-shaped sealing strip is extruded, high-temperature shaping is quickly performed to ensure that the product appearance meets the requirements.

4. Microwave vulcanization system: Microwave vulcanization refers to the method of vulcanizing using electromagnetic waves with a wavelength less than lm and a frequency of U.3 to 3UD MHO;. Microwaves have strong directivity and can penetrate bad conductors such as rubber, causing rubber molecules to oscillate and rub to generate heat on their own. Microwave heating does not cause the temperature difference between the inside and outside of the rubber product due to uneven heat conduction during normal heating and vulcanization, which is beneficial to improving the vulcanization quality of the system. Especially for the preheating and vulcanization of thick products such as tires, it can greatly shorten the vulcanization time. Microwave continuous vulcanization is simpler than other continuous vulcanization methods, has high vulcanization quality, saves energy, and significantly reduces costs.

5. Hot air vulcanization: The key to hot air vulcanization is to soften the raw rubber through heating, which then reacts chemically with the vulcanizing agent, transforming macromolecules from linear structures into macromolecules with three-dimensional network structures, thus significantly Improve the performance of rubber products, including strength, elasticity, wear resistance and corrosion resistance, etc.

6. Cooling system: usually includes a water tank or cooling roller, which is used to cool and shape the extruded rubber sealing strip.

7. Traction device: used to pull out the extruded sealing strip stably to ensure its uniformity.

8. Cutting equipment: Cut the sealing strip to the required length as needed.

9. Control system: used to regulate and monitor various parameters of the extrusion process, such as temperature, pressure and speed.

 

Parameter:

Extrusion process flow:

1. Batching and mixing: Mix the rubber raw materials and various additives evenly according to the formula ratio.

2. Feeding: Add the mixed materials to the feeding port of the extruder.
 

3. Heating and plasticizing: The extruder pushes the material forward through the rotation of the screw, and heats the material to the appropriate temperature through the heater to plasticize it.
 

4. Extrusion molding: The material is extruded through the mold to form the required sealing strip shape.
 

5. Cooling and shaping: The extruded sealing strip is cooled by the cooling system to ensure its stable shape.
 

6. Traction and winding: The cooled sealing strip is pulled out through the traction device and wound or cut as needed

Advantages

1. Efficient production: The extrusion process is characterized by efficient and continuous production.
 

2. Diversification: Sealing strips of various shapes and specifications can be produced to meet different application requirements.
 

3. Stable quality: The consistency of product quality can be guaranteed by precisely controlling the extrusion parameters.
