Thermal Break Rolling Machine Models

All models use the same mechanical rolling process, with different levels of tool positioning and adjustment. Choose a configuration based on your profile range, changeover frequency and production requirements.

Every machine is evaluated against your profile drawings before the order is confirmed. If you have a special profile or need a configuration beyond the models shown, contact us for a technical assessment. See all 13 models in the range →

02 / Overview

Thermal Break Rolling Crimping Machines for Aluminum Profiles

After knurling and PA66 strip insertion, aluminum profiles pass through the rolling machine. Multiple rolling stations apply controlled pressure to secure the polyamide strips inside the aluminum profiles, forming a mechanically joined thermal break profile.

MAKERL offers conventional and CNC rolling configurations for different profile dimensions, strip designs and production requirements. CNC models are particularly suitable for manufacturers handling multiple profile specifications and frequent changeovers.

Looking for a suitable model?

Send us your aluminum profile drawings, cross-sections and production requirements. Our team can help assess the appropriate rolling configuration.

Rolling stations are configured for each profile family. New profile series may require different tooling, but not necessarily a new machine.

03 / Why MAKERL

Why Choose a MAKERL Thermal Break Rolling Machine?

Secure mechanical connection

Hardened rolling tools apply controlled pressure to lock the PA66 strip into the knurled aluminum profile. Proper roller positioning helps create a stable connection while minimizing profile deformation.

Adjustment for different profile designs

Different profile sections require different roller positions and pressure settings. Depending on the model, adjustable tooling and CNC positioning help accommodate different profile dimensions and thermal barrier designs.

CNC control for repeatable production

CNC models support stored processing parameters for compatible profile specifications. Operators can recall saved settings during changeovers, reducing repeated manual adjustments and helping maintain consistent production settings.

Configurations for different production needs

From conventional rolling machines to multi-axis CNC configurations, MAKERL provides options for manufacturers with different product ranges, changeover frequencies and automation requirements.

04 / Process

How the Thermal Break Rolling Process Works

The rolling machine completes the final mechanical assembly stage after profile knurling and PA66 strip insertion.

STEP 01

Profile Knurling

The inner grooves of aluminum profiles are knurled to create the required mechanical engagement surfaces.

STEP 02

PA66 Strip Insertion

Polyamide thermal barrier strips are inserted into the prepared profile grooves.

STEP 03

Rolling and Crimping

The assembled profiles pass through multiple rolling stations, where the tools apply controlled pressure to secure the strips inside the aluminum profiles.

STEP 04

Quality Inspection

Finished profiles are checked for dimensions, appearance and connection strength according to the manufacturer’s quality requirements.

Correct roller positioning and pressure settings are important. Excessive pressure may deform a profile, while insufficient pressure may result in an inadequate connection. Final settings should be established through profile trials and appropriate quality testing.

06 / Applications

Applications of Thermal Break Rolling Machines

The MAKERL Thermal Break Rolling Machine is used in the production of thermally broken aluminum profiles for different building and industrial applications.

Aluminum windows and doors

For casement, sliding and tilt-turn aluminum window and door profile systems.

Curtain wall systems

For facade mullions, transoms and larger aluminum sections requiring thermal insulation.

Skylights and roof glazing

For aluminum profiles used in roof glazing and daylighting systems.

Energy-efficient building envelopes

For thermal break profiles used in low-energy and passive building systems.

Other aluminum extrusion products

For aluminum extrusion products that use polyamide thermal barrier strips.

07 / How to choose

How to Select the Right Thermal Break Rolling Machine

Before choosing a machine, consider the following points:

1 · Profile dimensions and shape

Provide the maximum profile width and height, together with cross-sectional drawings. Profiles with offset surfaces or different strip heights may require additional adjustment functions.

2 · Product range

If your factory produces only a few stable profile designs, a conventional configuration may be sufficient. For frequent changeovers and a wider range of profiles, consider a suitable CNC model.

3 · Production requirements

Discuss your target output, feeding arrangement and existing knurling and strip insertion equipment. These factors help determine the appropriate rolling configuration.

4 · Connection quality

The rolling setup should be validated using actual aluminum profiles and thermal barrier strips. Dimensional inspection and suitable connection-strength testing help verify the finished product.

08 / FAQ

Frequently Asked Questions

What does a thermal break rolling machine do?

It uses rolling pressure to mechanically secure PA66 polyamide strips inside knurled aluminum profiles, forming thermal break profiles for windows, doors and curtain wall systems.

Is a rolling machine the same as a crimping machine?

In thermal break aluminum profile production, rolling and crimping generally refer to the process of pressing and securing the aluminum profiles around the polyamide strips.

Can one machine process different aluminum profiles?

Yes, depending on the machine’s adjustment range and tooling configuration. Profile dimensions and cross-sectional drawings should be reviewed before confirming compatibility.

Should I choose a CNC rolling machine?

A conventional machine may be suitable for stable product specifications. CNC models are worth considering when processing multiple profile designs or handling frequent changeovers.

How can I confirm whether the machine suits my profiles?

Send us your aluminum profile cross-section drawings, PA66 strip dimensions and production requirements. Our technical team can evaluate the tooling and machine configuration.
