Understanding the role of different machines in rubber processing process

Rubber industry is one of the major forms of saleable industrial sector. Its fabrication and treatment requires different machines to purify it and convert into the rubber which we generally find in many of our daily use products. Rubber is extracted from trunks and barks of rubber trees. Though, at the time of extraction it remains in its natural form called latex that contains the qualities of rubber which is technically known as elastomers or elasticity. After that, the natural latex is polymerized and processed into the commercial or synthetic rubber.

The rubber factories where this processing is done need several advanced equipment to establish the shape of the rubber. Rubber cutter machine and rubber crusher machine are two such machines used by almost all rubber manufacturing factories and mill. These machines produce some of the finest rubber which is used for various purposes. Let us understand about rubber crusher machines and some other machines used in rubber mill in detail.

  • Rubber crushers- It uses the centrifugal technology to compress the rubber which is reshaped further as per the need. It is made from nickel and chromium alloy which guarantees its long shelf life and efficiency.
  • Calendar machines– It is used in transforming rubber into thin layers which then shipped to various industries which need rubber in their product manufacturing procedure.
  • Open Mill- Rubber fabrication process is a mechanical task which requires rubbing, mixing and refinement of rubber before processing it. Open mill machine is used for this purpose. It is one of the most noteworthy forms of tool used in the rubber mils.

These machines are backbone of the rubber industry, without which it is impossible to form perfect rubber. Therefore, it is vital for every rubber mill owner to get the right machines for rubber production. There are many rubber machine manufacturers which offer latest machines at reasonable rates.

Understanding overall meaning of machine tool

A machine tool is a used for shaping metal or other inflexible materials, normally by boring, cutting, grinding, shearing, or other types of bending. Machine tools utilize some kind of equipment that does cutting and shaping. All machine tools have some means of restraining the work piece and supply a guided movement of the parts of the machine. Thus the comparative movement between the cutting tool and work piece is controlled or guarded by the machine to at least some degree, rather than being entirely “offhand”.


Today machine tools are usually powered other than by human power (e.g. hydraulically or electrically) used to make manufactured parts in many ways that include cutting or some other kinds of buckling.

Machine tools can be operated manually, or under mechanical control. Early machines used flywheels to alleviate their movement and had compound systems of gears and levers to manage the machine and the piece being worked on.

After WWII, the numerical control (NC) machine was invented. These machines used a series of numbers punched on punched cards or paper tape to control their motion. In 1960s, computers were added to the machine give more flexibility to the course of action. Such machines are known as computerized numerical control (CNC) machines. NC and CNC machines could exactly repeat sequences time and again, and could produce much more intricate pieces than even the most expert tool operators.


Before long, the machines could involuntarily change the particular cutting and shaping equipment that were being used. For instance, a drill machine might contain an arsenal with many drill bits for producing holes of diverse sizes. Until that time, either machine operators would generally have to manually change the bit or move the work piece to another station to perform these dissimilar actions. The next rational step was to join different machine equipment together, all under computer control. These are known as machining centers, and have noticeably changed the method parts are made.

From the simplest to the most multifaceted, most machine equipment are competent of at least fractional self-replication, and produce machine parts as their key function. Some of the examples of machine tools are as follows:

Broaching machine

Gear Shaper

Drill press

Hobbing machine



Screw machines

Milling machine



Stewart platform mills

Multitasking machines

Rubber cutter machine

Ever since the use of plastics in all shapes and forms has become widespread, rubber manufacturing industry has gained in size and importance. Humans use plastics in various different ways which require rubber to be cut and manufactured in various different ways for meeting different plastic requirements. A central process of any rubber manufacturing plant is the cutting of rubber into appropriate sizes and shapes depending upon the requirement, which is where rubber cutting machines come into play. The primary function of a rubber cutting machine is to cut any type of rubber, be it natural rubber or synthetic rubber or even any other composite material, quickly and accurately, into specified shape, size and length.


Rubber cutter machines come equipped with very low knife speed and high speed torque motor to prevent heat buildup and minimize friction between surfaces. There is a wide range of models to choose from with varied cutting capacities ranging from a minimum of 3 inches to a maximum of 48 inches lengths. Based on your specific material and length requirement, you can choose a rubber cutter machine that not only falls within your budget but also provides you with the most accurate cutting length.

Quality plays a very important role when choosing a rubber cutter machine since rubber strips needs to be cut to exact shape and size with minimum wastage and in the lowest possible cycle time. Rubber cutter machines are available in both manual and automatic mode and choice of model should be based on the thickness and nature of material being cut. Materials can include not only rubber, but also coated textiles, silicone, laminates, foam and even PU and leather. They can also come in various forms like sheets, tubes, strips, cords, blocks and rolls. With the advent of computer controlled rubber cutter machines, it is possible for one machine to perform an array of cutting tasks from varied angles and positions. However not every rubber cutting task needs an advanced rubber cutting machinery. Basic simple cutting tasks can be performed by even manual rubber cutting machines. Since investing in a rubber cutting machine is a one time activity, it is best to consult manufacturers before deciding upon which machinery can best serve your purpose and budget.

Modern forms of rubber are however making it imperative for rubber manufacturing units to employ greater flexibility in its operations which is why many units are finding it a more feasible option to investing in a higher grade machine simply as a bet against future investments.

Twin Screw Roller Head Extruder

Twin Screw roller head extruder represents a significant advancement over the sheeting mill and dump mill technique used in traditional mixing lines that consumes more energy and does not produce half the required quality. With a twin screw roller head extruder, the mixed compound is transferred directly from the internal mixer into the machinery to be converted into high quality smooth, seamless rubber sheets that are then fed into the batch-off cooling machine. It is also far safer than the traditional mill apparatus and also far more reliable.


Once the compound is fed into the twin screw roller head extruder, it is heated up with the help of screws and heaters present in the machine. Heated rubber is then molded into specified shapes and extruded onto the cooling line. It comprises of a highly specialized twin screw extruder with an inclined roller-head and is widely used in manufacturing processes related to the production of industrial rubber goods, belts and hose as well as tire manufacturing.


Twin Screw roller head extruder offers many advantages over traditional dump mill rubber production. It has a more diverse application portfolio and can be used for industries as diverse as tire production and industrial rubber production. But its biggest advantage lies in the fact that it offers a significant energy saving over traditional machinery. By avoiding the use of double machinery for the mixing and cutting of rubber into shapes twin screw roller head extruder enables organizations to reduce energy consumption by more than 15%. Also the use of twin roller extractors helps reduce labor costs as it eliminates the need for manually performing rubber sheeting function. Reduced labor leads to fewer accidents and less wage cost which all adds upto lower production costs and ultimately lower rubber cost.

One reason why twin screw roller head extruder is so popular is the fact that is produces higher quality rubber by reducing exposure of rubber to air and dirt. In a traditional production environment, rubber travels from the internal mixer onto the sheeting machinery and there is the risk of contamination due to the exposure of the rubber to outside air and the dirt, moisture and pollutants present therein. In a twin screw roller head extruder, since the mixing and sheeting process is performed by a single piece of equipment in a closed environment, there is no contamination due to exposure leading to a higher quality output of rubber.



Internal mixer

One of the most widely used and important machinery in the rubber industry, internal mixers are used to mix together rubber materials to produce different kinds of rubber for use in various industries. Internal mixers play a very important role because it ultimately determines the functional characteristics of the final rubber product, which is why there is a huge selection of internal mixers available in the market based on different mixing needs. Mixing needs in turn are determined by the kind of rubber compounds to be mixed, quality requirement as well as the production need.

The two most popular categories of internal mixers include Tangential and Intermeshing Mixers and choice of one or both is based on the production need. For instance industrial rubber production requires intermeshing mixers since quality is a paramount factor. The tire manufacturing industry on the other hand requires tangential mixers since productivity plays a more significant role there. However the introduction of modern materials like silicone and emphasis on fuel efficient technologies has led to the availability of a new range of internal mixers that are energy efficient and compliant with a wide range of materials and mixing technologies.

Advanced high performance internal mixers available today combined with improved mixing technologies are able to produce far better quality compounds in shorter batch times. They also consume much less energy and the final output has a greater product uniformity than what was available in the past. But the greatest innovation in mixers has been the introduction of customized internal mixers which allow each component of the mixer including the rotor and the chamber volume to be customized as per product requirements. They are also capable of adapting to a wider range of materials to provide greater value for money.

Internal mixers come with both manual and automated control options depending on different production environments. They also come equipped with water temperature controls to simplify operations and increase productivity. One of the biggest challenges for the rubber industry has been to marry the speed of production with quality since running internal mixers at very high speeds causes excessive heating which has the potential to damage the rubber mix inside unless cooled immediately. However modern internal mixers come fitted with advanced rotors that are capable of functioning at high speeds in a temperature controlled environment. This improvement in internal mixers is one of the most important factors behind the improved quality of rubber available in the market today.
