OMS shrinkless expander is such an expander that both tube ends are secured before expanding. The design saves copper tube by 2.5%-3% and power consumption by 50%.
It is a patented design of OMS, and has been highly regarded by our customers because of its help in reducing production cost. In 2011, it was accredited as “High Technology Product” by Chinese government.
If you are looking for cost savings, OMS shrinkless expander will be a great choice.
Features:
1. Tube expanding, end flaring and flanging are done in one process.
2. Shrinless expanding. Save tubes and energy.
3. Expanding rods can be secured quickly. A protection mechanism prevents damage to the expanding rod.
4. Highly automated, which reduces labor intensity.
5. The machine can run for 24 hours each day with sound performance. Its low failure rate allows for mass production.
6. The design takes ergonomics into consideration. The machine is easy to operate, requiring only low maintenance. The noise level is low.
7. In the case of failure, the control panel screen will display causes and provide solutions, to enhance efficiency.
