Tired of Vibration Marks Ruining Your High-Value Aluminum Profiles?

You’ve invested in a top-of-the-line extrusion press and premium dies. You’ve optimized your heating process and alloy composition. But when the profiles come off the line, they’re covered in faint but unmistakable vibration marks – defects that turn your high-value EV battery trays and architectural curtain walls into cheap scrap.

This is the silent frustration of every extrusion manufacturer. Traditional Double-Head Pullers create an unavoidable 2-3 second handover gap between cycles. When the second head slams into the hot profile to take over traction, it sends a shockwave through the entire length of the material. The result is a visible vibration pattern that cannot be removed by polishing or coating.

The solution is Tongzheng’s 2000T-7500T Three-Head Double-Rail Puller. Our innovative alternating traction design eliminates handover gaps entirely. While one head is pulling the profile, the second head is already in position, moving at exactly the same speed as the extrusion. When the synchronous saw cuts the profile, the second head takes over seamlessly with zero impact.

The results speak for themselves: 99% elimination of vibration marks, a 20% increase in finished product yield, and the ability to produce high-value profiles that command premium prices. One of our customers in the EV industry reported that after installing our puller, their scrap rate dropped from 18% to just 2%, saving them over $300,000 annually in material costs alone.

Additionally, the continuous operation allows your extrusion press to run at full speed 24/7, increasing overall production output by 30%. This means you can fulfill more orders in less time and take on larger contracts that were previously out of reach.

If vibration marks are eating into your profits, it’s time to stop treating the symptoms and fix the problem at the source. Contact Tongzheng today to schedule a free consultation and see how our three-head puller can transform your production quality.
