4 Head Aluminium Profile Corner Crimping Machine – High-Speed Precision for Aluminium Window & Door Manufacturing

Introduction: Why Corner Crimping Machines Are Crucial

In the manufacturing of aluminium windows, doors, facades, and curtain walls, one of the most important stages is the joining of frame profiles at the corners. Unlike PVC/uPVC frames, which are welded with heat, aluminium profiles are connected through mechanical crimping.

The 4 head aluminium profile corner crimping machine is designed to handle this task with maximum efficiency and precision. By simultaneously crimping all four corners of a frame in one cycle, this machine ensures perfect squareness, stability, and strength while dramatically reducing production time.

This makes it a must-have for medium to large-scale factories that want to meet the rising demand for aluminium-based architectural systems.

What Is a 4 Head Aluminium Profile Corner Crimping Machine?

A 4 head aluminium profile corner crimping machine is a heavy-duty, fully automatic industrial machine used to assemble aluminium window and door frames.

Instead of welding, the machine uses hydraulic or pneumatic pressure to press corner connectors into the aluminium profiles. The four heads operate simultaneously, joining all four corners of a frame at once.

This results in:

• Perfectly square frames without manual alignment.

• Stronger mechanical joints with consistent accuracy.

• Faster cycle times, ideal for industrial mass production.

  • Slow, labor-intensive.

• Double Head Machine:

  • Crimps two corners simultaneously.

  • Medium productivity.

  • Common in mid-sized factories.

• 4 Head Machine:

  • Crimps all four corners in one cycle.

  • Highest productivity and consistency.

  • Essential for industrial-scale production.
