Function:

1. Heat Transfer and Fusion:
   The mandrel heats the inner surface of plastic pipes to a precise temperature, allowing them to fuse seamlessly under pressure. It ensures uniform heat distribution, critical for forming a leak-proof, durable joint 

2. Non-Stick Performance:
   Coated with a non-stick material , it prevents molten plastic from adhering to the tool. This reduces cleanup time, avoids material residue buildup, and ensures consistent fusion quality 

3. Precision Alignment and Support:
   In processes like numerical control (NC) bending or pipe fusion, the mandrel maintains the pipe's internal diameter during heating and cooling, preventing deformities like wrinkling or collapse 

4. Enhanced Efficiency:
   The non-stick properties minimize downtime for cleaning and extend the tool's lifespan, making it ideal for high-volume industrial applications (e.g., plumbing, gas pipelines, or hydraulic systems) 

Structure:

1. Material Composition:

   • Core Material: Made of stainless steel (e.g., Grade 304 or 316) for high thermal conductivity, corrosion resistance, and structural durability 

   • Coating: Features a non-stick layer (e.g., PTFE) applied to the surface. This coating withstands high temperatures (typically 200-300°C) and reduces friction 

2. Design Features:

   • Cylindrical or Bulb Shape: Depending on the application, it may be cylindrical (for basic fusion) or bulb-shaped (for enhanced support in bending processes). Bulb mandrels are more effective in reducing cross-section deformation 

   • Heating Element Integration: Often includes embedded electric heating elements for uniform temperature control.

   • Mounting Mechanisms: Some designs allow screw-in or press-in installation for stability during operation 

3. Key Parameters:

   • Diameter and Length: Tailored to the pipe's inner diameter. For example, mandrels for small-diameter tubes (e.g., 2169 stainless steel tubes) prioritize precise extension length to minimize wall thinning 

   • Clamping Features: Advanced versions (e.g., centering clamping mandrels) include clamping screws to secure workpieces, achieving high holding forces (e.g., up to 8.5 kN) 

4. Specialized Variants:

   • Screw-In Mandrels: Used in fixture construction for exact positioning and repeatability 

   • Flexible Mandrels: For complex geometries, allowing adaptation to bore diameters via machining
