Lock seam tube roll forming machine is a kind of metal coil forming equipment used to produce non-welded square tubes and rectangular hollow profiles. The equipment is continuously formed through multiple sets of rollers and uses mechanical locking process to close the metal edge, so there is no need for welding process in the whole production process.

This kind of roller forming production line is mainly used in the production of thin-walled hollow profiles, ceiling keels, gypsum board frames, metal linings, decorative pipes and light building profiles. For non-load-bearing or light metal profile manufacturers who need stable output, high production speed and low production costs, the lock seam tube roll forming machine is an economical and practical choice.

The main features of the lock seam tube roll forming machine

The lock seam tube forming machine adopts advanced technology to produce bite pipes that do not require welding efficiently and reliably. It is suitable for the manufacture of square and rectangular hollow profiles. It is specially designed for processing thin-walled metal coils using continuous cold roll forming roller pressing and forming technology. The equipment adopts customized roller design according to different product drawings to ensure accurate molding and form a stable and reliable bite structure. The lock seam tube roll forming machine is equipped with automatic fixed-length cutting function and PLC control system (including user-friendly touch screen operation interface), which realizes accurate and convenient production operation.

In addition, the equipment also provides optional functions such as punching, embossing, logo printing and online coding to meet diversified production needs. It supports a variety of materials, including galvanized steel, colored steel and aluminum, providing flexible solutions for different application scenarios.

The main applications of lock seam hollow profiles

Locked hollow profiles are usually used in scenarios that require lightweight, economical and easy installation.

1.Gypsum board ceiling system

Small-sized lock joint hollow profiles are often used for:

• Gypsum board ceiling system
• Ceiling support structure
• Indoor ceiling frame
• Used as a light support component.

It is especially suitable for some markets that prefer thin-walled hollow profiles.

2.Ceiling keel and metal frame

• Indoor ceiling project
• Decoration project

It can be used as a substitute for wooden keel.

3. Aluminum decorative pipe

• Decorative ceiling
• Wall decoration
• Interior decoration application

FAQ

1.What is the correct English name of the device?

The most accurate name is “Lock Seam Tube Roll Forming Machine”. If the finished product is a square or rectangular hollow profile, it can also be called a “lock seam square tube cold roll forming machine”.

2.Is this the same as the welding square pipe production line?

It’s different. The welded square pipe production line closes the pipe through welding process; while the bite-mouth pipe cold roll forming machine closes the profile by mechanical bite, so it is suitable for the production of non-welded hollow profiles.

3.Can this equipment produce suspended hollow profiles?

Yes. According to the profile drawings, the lock seam tube roll forming machine can be designed to produce ceiling hollow profiles, gypsum board ceiling keels, partition wall keels and metal ceiling hanging strips, etc.

4.Can aluminum coils be used as raw materials?

Yes, the premise is that the grade, hardness and thickness of the aluminum are suitable for cold roll forming and bite closure technology. In addition, the design of the roller must also match the materials used.

5.What information needs to be provided before the quotation?

Profile drawings or samples are the most important. In addition, we also need to know information such as material type, thickness, production speed requirements, cutting length and local voltage.
