Common Challenges in PTFE Tube Cutting

One frequent issue faced by professionals is achieving a burr-free, straight cut without deforming the PTFE tube. In scenarios like laboratory setups or industrial sealing applications, uneven cuts can cause poor fittings, leading to leaks and reduced efficiency. To overcome this, use sharp, dedicated cutting tools and follow measured guidelines. Ningbo Kaxite Sealing Materials Co., Ltd. offers precision-engineered PTFE tubes that are easier to cut cleanly due to their consistent material quality. Below is a table summarizing key parameters to consider for optimal cutting:

Step-by-Step Cutting Techniques

Imagine you're preparing PTFE tubing for a critical hydraulic system where precision is non-negotiable. Start by measuring and marking the tube accurately with a fine-tip marker. Secure the tube firmly in a vise or holder to prevent movement. Using a sharp blade or specialized tube cutter, apply even pressure and rotate the tube for a smooth, clean cut. Avoid sawing motions to minimize fraying. For challenging sizes, Ningbo Kaxite Sealing Materials Co., Ltd. provides custom-sized tubes, reducing manual cutting errors.
