Foaming extrusion: Thermoplastic elastomer tpv can be foamed by chemical and mechanical methods. For chemical foaming, foaming agents such as bihydrochloride can be used. The achievable foam density specific gravity ranges from 0.97 (typical unfoamed tpv) to 0.70. The lower density is affected by patents. Blowing agents will degrade at 180°C to 190°C, because most of the tpv base is...

Hopper cylinder – The rubber extruder machine is made of cast steel and is jacketed for water-cooling. The insides are made wear resistant by chrome plating or nitrited alloy steel. The insides also have spiral undercuts for high feeding efficiency. Rollfeeder – The feed roll is operated by the screw by the means of a gear and pinion. The feed roll surface is hardened and an inside...

The rubber extruder manufacturer introduced some extrusion types: Hot ExtrusionHot extrusion, on the other hand, involves heating metal at high temperatures and then forcing it through the die while in a molten state. Depending on the type of metal, temperatures may range from 650 degrees Fahrenheit (magnesium) all the way to 1,300 degrees Fahrenheit (steel). It’s important for...

The function of the rubber extruder machine is to use heating, pressure and shearing methods to transform solid plastic into a uniform melt and send the melt to the next process. The production of the melt involves the process of mixing additives such as color masterbatches, blending resins, and pulverizing. The finished melt must be uniform in concentration and temperature. The pressure must...

The rubber extruder machine begins with a rubber compound being fed into an extruder.Once the material reaches the die, the built-up pressure forces the material through the openings.After vulcanization, a length of rubber hot air oven will tend to be reduced in dimension more in the center of the length than in the ends. The rubber extruder solves the most critical issues manufacturers face to...

When choosing a rubber extruder machine, we must choose according to the size of the product. The maximum extrusion capacity of rubber extruders of different models is different. The types of rubber extruders are classified according to the diameter of the screw, that is to say, the larger the screw diameter of the rubber extruder, the greater the amount of rubber processed by the extruder...

The main function of the cold feed rubber extruder machine is extrusion molding, and most of the rubber extruders for extrusion molding are cold feed rubber extruders. Cold feed is defined relative to hot feed, which means whether hot glue needs to be fed at the feeding port when the rubber extruder is working, or both hot and cold glue can be fed. Generally, the way to distinguish between a...

The mechanical principle of the rubber extruder machine:Add water or appropriate liquid to the raw material powder, and continue to stir. Extrude the mixed material from the porous die or metal mesh with high extrusion pressure.Usually, after putting the material into a cylindrical container, the material is extruded with a screw. After using the frequency conversion technology, the pressure...

①The rubber extruder head should be assembled together and installed on the extruder as a whole. ②Before assembling the machine head, wipe off the grease applied during storage, carefully check the cavity surface for bruises, scratches, and rust spots, perform necessary polishing, and then apply a layer of silicone oil on the surface of the runner. ③Assemble the plates of the machine head in...

The rubber extruder machine plays the role of extrusion molding when producing rubber products. We need to choose the type of rubber extruder according to the type and characteristics of the product during production. No matter what kind of rubber extruder is in production, the rubber is sheared, compressed and mixed by the screw in the barrel. Therefore, the barrel and screw of the rubber...

Extrusion molding is a process in which a plastic material with a certain degree of plasticity is continuously pressed out through a mouth under certain conditions, so that it becomes a product with a certain cross-sectional shape. As the rubber material moves forward along the screw, the viscosity and plasticity of the rubber material change to a certain extent due to mechanical and thermal...

　　The structure of rubber extruder machine is usually composed of barrel, screw, feeding device, die (mouth), heating and cooling device, transmission system and other parts. 　　1, barrel 　　The barrel cooperates with the screw during work, so that the rubber material is subject to the interaction of the inner wall of the barrel and the rotating screw to ensure that the rubber material moves and...

The steps for debugging the rubber extruder machine are as follows: 　　 1. It is necessary to do a temperature control check before starting to make sure that the temperature control is normal, the instrument is normal, and the cooling water path is unblocked. 　　2. The screw, barrel and die of the rubber extruder need to be heated. Generally, the temperature reaches the appropriate temperature...
