Heat shrink tubing is widely used in electrical and electronics work to insulate wires, provide strain relief, and protect solder joints. Traditionally, a heat gun is the tool of choice for shrinking tubing evenly and efficiently. But can a hot air rework station serve the same purpose?
At Gordak Electric, we understand that technicians often look for versatile tools to optimize their workspace. This article explores whether a hot air rework station can be used for heat shrink tubing, its advantages, limitations, and best practices.
Is a Hot Air Rework Station Suitable for Heat Shrink Tubing?
A hot air rework station generates controlled, focused streams of heated air primarily designed for soldering and desoldering surface-mounted components on PCBs. Because of its precise temperature control and adjustable airflow, it can be used to shrink heat shrink tubing—especially in small or delicate applications where a traditional heat gun’s broad airflow might be too intense.
However, there are some important considerations:
- Nozzle size and airflow: Hot air stations typically have smaller nozzles designed for focused heat. For larger tubing, shrinking might be slower compared to a heat gun’s wider nozzle.
- Temperature range: The station’s temperature settings usually suffice to shrink common heat shrink tubing (typically 90°C–200°C), but always confirm your tubing’s specifications.
- Work area size: Hot air rework stations are best for precise, small-area heating rather than broad heat application.
Advantages of Using a Hot Air Rework Station for Heat Shrink Tubing
- Precise temperature and airflow control prevent overheating or damaging sensitive components nearby.
- Focused heating is ideal for shrinking tubing around small connectors or delicate electronics.
- Compact and versatile tool reduces the need for multiple devices on the workbench.
Limitations Compared to a Heat Gun
- Longer shrink time for large or thick tubing due to lower airflow volume.
- Limited coverage area, making it impractical for bulk wiring tasks.
- Potential nozzle compatibility issues if tubing diameter exceeds nozzle size.
Best Practices for Using a Hot Air Rework Station on Heat Shrink Tubing
- Select the appropriate nozzle size to direct airflow evenly around the tubing.
- Set the temperature according to the tubing manufacturer’s recommended shrinking temperature.
- Maintain a safe distance (usually 2–4 cm) from the tubing to avoid overheating.
- Move the nozzle in slow, circular motions to ensure uniform heating and shrinking.
- Avoid direct contact between the nozzle and tubing to prevent melting or burning.
Conclusion
While a hot air rework station is not traditionally marketed as a dedicated tool for heat shrink tubing, it can effectively perform this function for small, precise tasks—especially when working near sensitive electronic components. For larger or general wiring jobs, a dedicated heat gun remains the preferred tool.
