A Guide to Micro bore Tubing

The new and innovative ideas using vacuum sizing for micro bore tubing are making a huge difference in the medical field.  Although this technique dates back to the 1950s, the more modified and modern form established in the 1980s. The idea behind vacuum sizing for micro bore tubing is the use of extrusion freely. It enhances the entire procedure by developing a way of processing materials that had tacky nature and extreme flexibility.

Another reason to incorporate vacuum sizing in micro bore tubing is to improve the sizes of the tubing available. A micro bore tube usually has a diameter of 0.03 inches and a wall of 0.005 inches.

The use of the vacuum sizing principle is very successful in the production of micro bore tubes.  The major changes include the cross-section at smaller tanks, very low disturbance rate, vacuum cooling, and much more.

What is Micro bore Tubing?

Micro bore tubing is normally lesser in diameter than macro bore tubing. The internal diameter can vary due to the manufacturing differences. They often range from 0.5 to 1.5 millimeters. Moreover, the tackiness of the materials used in the tubing also affects the performance and efficiency.

Free Extrusion Vacuum Sizing for Micro bore Tubing

We can successfully say that the use of vacuum sizing can drastically improve the manufacturing procedure by rendering online cutting.  This has the least amount of effect on the dimension and stability by miniaturizing the drawdown which guarantees roundedness for multi-lumen tubing.

When deciding to go for free extrusion vacuum sizing the internal air regulation system introduces very precise air pressure.  This occurs through you either a single or multiple cavities that are in the structure of the die.  It allows the cavity to fill up at a constant speed.

The heat transfusion rate is very slow yet consistent which helps in determining the amount of drawdown taking place within the die and the tank. Here, the air and heat pressure increases and decreases gradually to create variations in the size, diameter, and thickness of the micro bore tubing. This step is extremely vital for maintaining the size of the tubes.

This complete procedure is very precise and controlled due to using different levels of air and water pressures. The only limitation is to maintain the roundedness of the tube which becomes difficult due to free extrusion in vacuum sizing. This is why; there can be irregularities in the thickness of the wall as well as the shape of each lumen which can vary due to their different cooling rates.

Moreover, it is imperative to work on maintaining the evenness in the micro bore tube structure in order to get efficient and effective results.

Vacuum Sizing for Micro bore Tubing

The main motive behind the medical tubing usage includes its miniature size.  The more the tube falls on the smaller side, the more it is effective and more useful for different types of medical procedures.  More than ever now is the time when we need the roundedness, dimensional precision, and higher presence level in the performance of the single, double, and multiple lumens micro bore tubing.

Many researchers are coming up with sizing techniques that involve the use of vacuum. This is why vacuum sizing is becoming all the rage in the manufacturing of different medical tubing. Also, they owe its popularity to the increased number of advanced results of using the vacuuming technique.

It is facilitating many processes in incorporating different materials in a single tube thus increasing the performance level by manifolds. Another major improvement has occurred in miniaturizing the size to improve the quality of the previous tubes.

There are some major steps involved in vacuum sizing for micro tubing. It makes use of different vacuum pressures.  This vacuum is forced in order to make adjustments in the sizing requirements. During this process, the external heat remains constant for keeping the external diameter intact.

After the tube exits the sizing equipment, it stays within the vacuumed cavity. Here the vacuum acts as an external force on the tube by maintaining its roundness. In most scenarios, water rings help in employing the creation of sealants that lubricate the extrudate. This allows them to handle the stickiness that may occur in the early vacuum calibration.

Water rings are a great way to introduce a thin cooling layer outside the actual tube to protect the structure and roundness before they come in contact with the vacuum.

Vacuum Calibration Tooling for Micro bore Tubing

There are many researchers who are working on developing different sizing tools with the help of using vacuum calibration.  This is very important to manufacture micro bore tubing in order to use different polymer materials to incorporate the maximum amount of features and qualities in a single tube.

In order to successfully manufacture the tube, these sizing tools make use of a slightly larger mold that reduces in size after departing the sizing tool. It totally depends on the nature, features, and characteristics of the polymers used.

Moreover, the vacuum cavity must have adequate levels that match the requirement of the tubing size. It is almost the same for most of the polymers thus; it is the most approachable technique as well. This is because it ensures the roundness of the tube which is the most desirable trait in any micro bore tubing.

Conclusion

It is undeniable that vacuum sizing for Micro Bore tubing is a popular way of obtaining error-free tubing solutions. Hence, it can easily overtake the free extrusion for attaining tubes by providing much better quality and efficient micro bore tubes. It eradicates the excess air by creating a vacuumed cavity that works hand in hand with pressure tactics.

Moreover, it can help in reducing production costs as well as reducing time consumption. It has become a viable and sustainable option for different medical problems. However, there is a scope for more improvements and innovations for keeping up with the benchmark provided by the medical community.
