- Precision Engineering: Computer-aided design (CAD) and computer-aided manufacturing (CAM) techniques allow for the creation of highly accurate mandrels with intricate geometries. This precision ensures consistent expansion and minimizes the risk of damage to the tubing.
- Innovative Expansion Mechanisms: Beyond simple tapered cones, modern mandrels employ advanced mechanisms such as hydraulic or pneumatic expansion, offering greater control over the expansion process. This allows for precise adjustment of expansion force, crucial for delicate materials.
- Integrated Measurement and Control: Some advanced mandrels incorporate sensors and data acquisition systems. These systems monitor expansion force, tube diameter, and other parameters in real-time, providing valuable feedback for quality control and process optimization. This eliminates guesswork and ensures consistent results.
- Modular Design: Many modern mandrels are modular, allowing for easy adaptation to different tube sizes and materials. This flexibility reduces the need for a large inventory of mandrels and speeds up setup times.
