Assembly line models in this range

Three platforms on one control architecture. Start with the model that matches your current output and add stations later without replacing the line. Each model has its own page with tooling, cycle time and layout details.

Every model is configured against your profile drawings before the order is confirmed. The 120–240 pcs/h and 2–3 operator figures refer to the typical 60–160 mm window and door profile range; wide curtain wall sections, frequent changeovers or manual loading will move the real number, so treat them as a starting point rather than a fixed rating. Missing a model you have seen elsewhere? Ask — most configurations are adaptations of these platforms.

02 / Overview

Automatic Thermal Break Profile Assembly Line

MAKERL provides automatic thermal break assembly lines for aluminum profiles, integrating profile knurling, polyamide strip insertion, rolling and crimping into one coordinated production process.

The line is designed for manufacturers producing thermally broken aluminum profiles for windows, doors, curtain walls and other applications. Machine configuration can be adjusted according to profile design, strip size, production capacity and factory layout.

A typical MAKERL configuration includes:

  • CNC profile knurling and strip insertion machine
  • Automatic profile transfer system
  • CNC rolling and crimping machine
  • Profile positioning and handling system
  • PLC control system
  • Touchscreen operation
  • Production parameter management

The actual configuration can be selected according to your profile dimensions, strip specifications, production target and available factory space.

Profile cross-sections the line supports: standard, misalignment-tolerant and curtain wall sections

Profile cross-section families the line is configured for. Send your drawings to confirm tooling.

03 / Process

How Does a Thermal Break Assembly Line Work?

A thermal break assembly line combines several processing stages to join aluminum profiles with a polyamide thermal barrier strip. The standard process includes three main stages.

STAGE 01

Profile Knurling

The aluminum profile is processed before strip insertion. Knurling creates the required mechanical engagement surface inside the profile grooves.

Parameters adjusted to profile design
STAGE 02

Polyamide Strip Insertion

The PA66 polyamide thermal barrier strip is inserted into the prepared aluminum profile grooves.

Profile positioning + strip feeding controlled
STAGE 03

Rolling and Crimping

Controlled rolling pressure deforms the aluminum profile around the thermal barrier strip and creates the required mechanical connection between the aluminum profile and PA66 strip.

Finished Thermal Break Profile

The finished profile leaves the crimping section ready for downstream fabrication.

04 / Applications

Applications

Thermal break assembly lines are used for the production of thermally broken aluminum profiles for:

Aluminum windows and doors

Casement, sliding and tilt-turn profile families

Curtain wall systems

Large-section mullions and transoms

Skylights

Roof glazing and daylighting profiles

Passive house & low-energy buildings

High-performance thermal barrier profiles

Rail transit windows

Rolling stock and coach glazing frames

Caravan & specialty vehicle frames

Lightweight insulated body profiles

Other aluminum profile applications requiring thermal insulation are also supported. The suitable machine configuration depends on the profile geometry, thermal barrier strip and production requirements.

05 / Machine or line

Thermal Break Assembly Machine or Complete Assembly Line?

A single thermal break assembly machine can be suitable for manufacturers with smaller production volumes or existing equipment. A complete assembly line is more suitable when the goal is continuous production with coordinated profile handling between different processes.

08 / FAQ

FAQ

What is a thermal break assembly line?

A thermal break assembly line is a production system used to combine aluminum profiles with a thermal barrier strip. The process typically includes profile knurling, polyamide strip insertion, rolling and crimping.

What processes are included in the assembly line?

A standard line includes profile knurling, PA66 polyamide strip insertion, profile transfer and rolling and crimping. The exact configuration can be adjusted according to production requirements.

How many operators are required?

A fully automatic thermal break assembly line can typically be operated by 2–3 people, depending on the line configuration and material handling method.

What is the production capacity?

The typical production capacity of the automatic line is approximately 120–240 pieces per hour. Actual output depends on profile length, processing parameters and production conditions.

Can the assembly line process different aluminum profiles?

Yes. The line can be configured for different thermal break aluminum profiles. Profile drawings and technical specifications should be provided before confirming the machine configuration.

Can MAKERL provide installation and training?

Yes. MAKERL can provide installation support, commissioning and operator training as part of the machine delivery and project setup.
