How much do you know about elastomer extruder?

There are many rubber products in our life. The car tires we usually see are made of rubber, and many products we usually see are made of rubber. There are many products that can be made in a single move, and they are very common in our lives. The bottoms of some soles are also made of rubber. When rubber is processed, a rubber extruder needs to be used. The elastomer extruder is a kind of equipment used for extrusion.

What is a plunger elastomer extruder?

The extruder originated in the 18th century, and the manual piston extruder for making seamless lead pipes made by Joseph Bramah of Inge in 1795 is considered to be the first extruder in the world. Since then, in the first 50 years of the 19th century, the plunger elastomer extruder was basically only used in the production of lead pipes, the processing of macaroni and other foods, the brick making and the ceramic industry.

What will happen to the deviation of the elastomer extruder head?

The deviation of the elastomer extruder head will cause uneven force! The higher the plasticity of the elastomer extruder, the smaller the elasticity, the better the fluidity of the rubber, and the smaller the extrusion deformation, and vice versa. The uniformity of the rubber is conducive to reducing extrusion deformation, but the plasticity of the rubber compound should not be too large, otherwise it will affect the stiffness of the semi-finished product and the physical and mechanical properties of the finished product.

Properly increasing the temperature of the elastomer extruder head can increase the fluidity and relaxation speed of the rubber compound, and can also reduce the extrusion deformation.

What are the working parameters of the elastomer extruder?

a. The working parameters of the elastomer extruder are main engine speed, main engine current, feeding speed, pelletizing speed, melt pressure, melt temperature, section temperature, etc.

b. There is no direct relationship between the speed of the main engine and the current, but the higher the speed is, the more electricity loss will be saved accordingly.

c. The feeding is generally semi-starved, so the size of the feeding is directly related to the extrusion production capacity.

d. The melt temperature is basically the actual temperature of the material; there is a gap between the section temperature and the actual material temperature, generally 5~20 degrees. This is the difference caused by whether the temperature probe is in contact with the material or not.
