How to bend Peeksil Tubing?

As a supplier of Peeksil Tubing, I've encountered numerous inquiries from customers regarding the bending process of this remarkable material. Peeksil Tubing combines the excellent properties of PEEK (Polyether Ether Ketone) and silicone, offering high strength, chemical resistance, and flexibility. In this blog, I'll share some professional insights and practical tips on how to bend Peeksil Tubing effectively.

Understanding Peeksil Tubing

Before delving into the bending process, it's crucial to understand the characteristics of Peeksil Tubing. This tubing is widely used in various industries, including medical, automotive, and aerospace, due to its outstanding performance. You can find more information about Peeksil Tubing on our official website: Peeksil Tubing.

Peeksil Tubing is known for its flexibility, which allows it to be bent into different shapes. However, improper bending techniques can lead to issues such as kinking, cracking, or deformation, which may affect the functionality of the tubing. Therefore, it's essential to follow the correct bending procedures to ensure the quality and integrity of the tubing.

Preparing for Bending

1. Select the Right Tubing: Different applications may require different sizes and specifications of Peeksil Tubing. Make sure to choose the appropriate tubing based on your specific needs. You can also explore our other PEEK tubing products, such as Green Peek Tubing and Peek Capillary Tubing, to find the best fit for your project.
2. Gather the Necessary Tools: To bend Peeksil Tubing, you'll need a few essential tools, including a bending jig, a heat source (such as a heat gun or an oven), and a measuring tool. The bending jig should be designed to match the desired bend radius and angle of the tubing.
3. Clean the Tubing: Before bending, it's important to clean the tubing to remove any dirt, debris, or contaminants that may affect the bending process. You can use a mild detergent and water to clean the tubing, and then dry it thoroughly.

Bending Techniques

There are several methods for bending Peeksil Tubing, each with its own advantages and limitations. The most common methods include heat bending and cold bending.

Heat Bending

Heat bending is the most widely used method for bending Peeksil Tubing, as it allows for greater flexibility and precision. Here's a step-by-step guide on how to heat bend Peeksil Tubing:

1. Set Up the Bending Jig: Place the bending jig on a flat and stable surface, and adjust it to the desired bend radius and angle. Make sure the jig is securely fastened to prevent any movement during the bending process.
2. Preheat the Tubing: Use a heat source to preheat the tubing to the appropriate temperature. The recommended preheating temperature for Peeksil Tubing is typically between 150°C and 200°C, depending on the specific type and thickness of the tubing. You can use a heat gun or an oven to preheat the tubing, but make sure to monitor the temperature carefully to avoid overheating.
3. Insert the Tubing into the Bending Jig: Once the tubing is preheated, carefully insert it into the bending jig, making sure it is centered and aligned with the desired bend radius and angle.
4. Apply Heat and Bend the Tubing: Use the heat source to apply heat to the area of the tubing that needs to be bent. Move the heat source slowly and evenly along the length of the tubing to ensure uniform heating. As the tubing softens, gently bend it around the bending jig to the desired angle. Make sure to apply even pressure to avoid kinking or cracking the tubing.
5. Cool the Tubing: After bending the tubing, allow it to cool down slowly to room temperature. You can use a fan or air flow to speed up the cooling process, but avoid quenching the tubing in water, as this can cause stress and cracking.
6. Remove the Tubing from the Bending Jig: Once the tubing has cooled down completely, carefully remove it from the bending jig. Inspect the tubing for any signs of damage or deformation, and make any necessary adjustments.

Cold Bending

Cold bending is a simpler and more straightforward method for bending Peeksil Tubing, but it may not be suitable for all applications. Here's a step-by-step guide on how to cold bend Peeksil Tubing:

1. Set Up the Bending Jig: Place the bending jig on a flat and stable surface, and adjust it to the desired bend radius and angle. Make sure the jig is securely fastened to prevent any movement during the bending process.
2. Insert the Tubing into the Bending Jig: Carefully insert the tubing into the bending jig, making sure it is centered and aligned with the desired bend radius and angle.
3. Bend the Tubing: Use your hands or a bending tool to gently bend the tubing around the bending jig to the desired angle. Make sure to apply even pressure to avoid kinking or cracking the tubing.
4. Inspect the Tubing: After bending the tubing, inspect it for any signs of damage or deformation. If necessary, make any adjustments to the bend radius or angle.

Tips and Tricks

1. Use a Mandrel: If you need to bend the tubing at a sharp angle or with a small bend radius, you can use a mandrel to support the inside of the tubing and prevent it from collapsing or kinking. The mandrel should be made of a material that is compatible with the tubing, such as stainless steel or aluminum.
2. Avoid Overbending: Overbending the tubing can cause it to crack or break, which may affect the functionality of the tubing. Make sure to follow the recommended bend radius and angle specifications for the tubing, and avoid bending it beyond its limits.
3. Practice on Scrap Tubing: If you're new to bending Peeksil Tubing, it's a good idea to practice on some scrap tubing first to get a feel for the bending process and to familiarize yourself with the tools and techniques.
4. Seek Professional Advice: If you have any questions or concerns about bending Peeksil Tubing, don't hesitate to seek professional advice from our technical support team. We're always here to help you find the best solution for your specific needs.
