Plastic bending saves time and money

​Plastic bending occurs when thermoplastic tubing is heated and reshaped without the need for cutting, welding, or fittings. This process results in a single piece of bent plastic tubing that can feature multiple angles or bends, tailored to meet specific design requirements.

Plastic bending offers significant time and cost savings because it eliminates the need to purchase and install separate Ts, elbows, or joints in the system. It’s an ideal solution for manufacturing environments with limited space or those requiring customized tubing configurations.

The Plastic Bending Process

For successful plastic bending, the use of raw tubing is essential. Tubing that is professionally cleaned and bagged by trusted suppliers minimizes contamination risks and ensures a clean production environment, particularly when working in cleanrooms.

Thermoplastic materials such as Polytetrafluoroethylene (PTFE), Polypropylene (PP), and Polyvinyl Chloride (PVC) are excellent candidates for bending. These materials maintain their structural integrity during the bending process, making them suitable for applications that require durability and precision. Common sizes of tubing range from 1/16-inch to 2 inches in diameter.

Key considerations during the process include:

• Consistent heat application: Ensures smooth bends without kinking or collapsing the tubing.
• Custom tooling and proprietary techniques: Axenics’ specialized methods achieve tighter tolerances and unique bend configurations.
• Length flexibility: Any length of thermoplastic tubing can be bent to meet project requirements.

Applications of Plastic Bending in High-Purity Industries

Plastic bending is essential in industries like semiconductor manufacturing and alternative energy, where high-purity components are critical. To maintain this level of purity, bending often occurs in cleanrooms, ensuring no contaminants compromise the tubing or systems.

Advantages of plastic bending for high-purity applications include:

• Reduced risk of contamination compared to metal tubing, which may experience flaking or weld-related issues.
• Corrosion resistance, making it ideal for transporting volatile chemicals or corrosive liquids.
• Enhanced durability in environments subject to mechanical vibrations, minimizing the risk of fatigue or failure.

Innovations in Plastic Bending

Improved Heat Distribution

One of the challenges in plastic bending is maintaining consistent heat across the tubing to avoid kinks or irregular bends. Axenics has developed innovative methods for distributing heat evenly throughout the tubing. These techniques ensure that every section of the bend maintains its structural integrity, reducing the risk of flow disruptions caused by trapped liquids or congealed substances.

Automated Plastic Bending Systems

Automation is transforming the plastic bending process. Axenics now incorporates automated bending systems into some projects, increasing precision and repeatability. Automation also reduces production times, allowing manufacturers to scale operations without sacrificing quality.

Benefits of Plastic Bending for Manufacturers

• Reduced Material Costs: Plastic bending minimizes raw material usage, as fewer fittings and welds are required.
• Leak Prevention: Eliminating welded joints significantly decreases the likelihood of leaks, improving overall system reliability.
• Custom Integration: Bent plastic tubes seamlessly integrate into existing production machinery without compromising performance.
• Vibration Resistance: Plastic tubing is more resistant to vibration fatigue compared to metal tubing, making it a more durable option for systems with moving components.

Choosing the Right Plastic for Your Project

The performance of bent plastic tubing depends on the environmental conditions of your manufacturing system, particularly temperature fluctuations. While thermoplastics like PTFE and PP are highly versatile, extreme heat can cause relaxation or weakening of the material. Selecting the right plastic for your project ensures durability and consistent performance over time.
