Standard FEP tubing can work well for many applications. However, some manufacturing processes need more control than a standard tube can provide. Tube size, wall thickness, length, expansion, and shrink performance can all affect production. Medical device manufacturers may also need custom processing equipment for repeatable results. A standard tube may be a good starting point, but it may not suit every production requirement.
A Standard Tube Does Not Fit Every Production Line
Manufacturing requirements can change from one application to another. One project may need a specific tube diameter. Another may require a certain length or wall thickness. Some applications also need tubing that shrinks to a controlled size during heating. Standard tubing comes with set dimensions and production characteristics. Those specifications may work perfectly for one application. Another project may need something more specific. Manufacturers should look at the complete production process before deciding that standard tubing is enough. The question is not simply about finding a tube that fits. The larger question is how that tube will behave throughout production.
What Does Your Application Actually Need?
A closer look at the application can reveal whether standard tubing will work. Start with the required outside diameter and inside diameter. Next, consider the tube wall thickness. The required tube length should also be clear. Some applications need tubing that will shrink around another component. Others use tubing during a manufacturing process and remove it later. Catheter manufacturers, for example, can use FEP shrink tubing during reflow. The tubing helps during production and is stripped away afterward. Other medical devices may use FEP as a functional component. Each use creates different production requirements. A manufacturer should also consider the number of tubes needed per day or production run.
Shrink Tubing Brings More Variables
Shrink tubing needs to perform differently from a simple tube. The tubing needs to respond to heat during the shrinking process. Its starting dimensions can affect the final result. The expansion process also needs careful control. FEP shrink tubing may be produced with specific dimensions for a particular manufacturing application. An incorrect size can affect how the tube fits around the component. A defect can create another problem during processing. Pin-holes or blow-outs can appear during tube expansion. Such defects can lead to rejected parts or wasted material. Production equipment can help identify and manage these issues.
When Does Custom Production Start Making Sense?
Custom production becomes useful when standard dimensions no longer match the application. A manufacturer may need unusual tube sizes or specific lengths. Another project may require higher control during expansion. Some applications also need automatic cutting after expansion. Those requirements call for more than a standard tube supplier. An FEP tubing manufacturer with suitable production equipment can work around specific requirements. Custom production can also help manufacturers reduce unnecessary manual steps. The goal is not to customize every tube simply because customization is possible. The goal is to create tubing that fits the actual manufacturing process.
What Happens When Quality Changes From One Tube to Another?
Consistency becomes important when every part needs to meet the same requirements. A production system should identify tubes that do not meet the required quality level. Pin-holes and blow-outs are examples of problems that can occur during expansion. The Engineering Resource Group's expansion machines include automated recovery for these issues. Its system can also separate parts based on quality information from the expander. That feature connects quality control with the next production step. Instead of treating inspection and cutting as completely separate tasks, the system links them together.
Cutting Lengths Manually Can Add Extra Work
Tube length may seem like a small detail. It can become a larger production issue during high-volume manufacturing. A small difference between pieces can create inconsistent parts. Manual cutting also adds another task for production staff. The Engineering Resource Group developed its proprietary Linear Cut-to-Length system for this purpose. The LCTL system is patent-protected. It can automatically separate tubing parts based on quality results from the expansion process. The system can also be used in two different ways. Manufacturers can integrate LCTL directly with the tubing expansion system. The system is also available as a stand-alone unit. That flexibility allows the equipment to fit different production setups.
Look at the Equipment Alongside the Tube
Choosing the right tube is only one part of the decision. The equipment used to expand and cut that tube can affect the overall production process. Manufacturers should consider how the tubing moves from one step to the next. Expansion may need specific controls. Cutting may need exact lengths. Quality information may also need to guide the next production step. An FEP tubing manufacturer with custom equipment capabilities can address these needs together. That approach can be useful when standard tubing alone does not solve the production problem.
What Could a More Complete System Look Like?
A more complete setup can begin with FEP shrink tubing. The tube enters an expansion machine and moves through the required process. Quality information can then identify acceptable and defective parts. The LCTL system can use that information when separating the tubing. Automatic recovery can also help handle certain expansion problems. The result is a process that connects several production steps. The Engineering Resource Group develops systems around this type of FEP tubing production. Its equipment is designed to support manufacturers with specialized requirements.
So, Is Standard FEP Tubing Enough?
Standard FEP tubing can be enough for straightforward applications. More demanding production processes may need custom dimensions or specialized equipment. The right answer depends on what happens after the tube is purchased. A medical device manufacturer may need controlled expansion, specific lengths, quality detection, or automated separation. Catheter manufacturers may need FEP shrink tubing for reflow processes. Other devices may use FEP as part of the finished product. Each application places different requirements on the tubing.
The Engineering Resource Group develops systems to produce FEP shrink tubing for specialized manufacturing needs. Its expansion machines can support controlled production and automated recovery. The company's patent-protected linear cut-to-length system adds automated cutting and part separation. LCTL works as a fully integrated part of the tubing expansion system or as a stand-alone system. For manufacturers asking if standard tubing is enough, the production process provides the answer. An FEP tubing manufacturer with custom equipment capabilities can help bridge the gap between standard tubing and specialized production needs.
