CNC Knurling and Strip Insertion Machine
Prepares the aluminum profile for thermal break assembly: CNC knurling creates the toothed groove surface, then the PA66 polyamide strip is inserted automatically.
Knurling & strip insertion models
Two machine platforms cover the knurling and insertion step — pick by groove geometry and how many profile series you change over in a shift. Both feed PA66 strip automatically.

Custom tooling for unusual grooves
Curtain-wall and wide-cavity profiles sometimes need dedicated knurl heads. Send the cross-section and we will confirm feasibility.

What Does the Machine Do?
Before the thermal barrier strip is inserted, the inner grooves of the aluminum profile are knurled to create a toothed surface. The PA66 strip is then inserted into the prepared grooves.
The processed profile can then move to the rolling and crimping stage, where the aluminum profile and thermal barrier strip are mechanically locked together.
Aluminum Profile → Knurling → PA66 Strip Insertion → Rolling & Crimping
Send us your aluminum profile drawings, thermal barrier strip specifications and production requirements. We can recommend a suitable knurling and strip insertion configuration for your application.
Machine settings are stored per profile series and recalled at changeover.
Key Features
Accurate knurling depth and consistent strip insertion maintain stable processing quality across batches.
Automatic profile positioning and strip feeding reduce repetitive manual work during production.
Servo-driven axes keep knurl depth and feed speed locked to the stored recipe.
Machine settings adjust to different thermal break profile designs and production requirements.
From Knurling to Finished Thermal Break Profile
The CNC Knurling and Strip Insertion Machine is one part of the complete thermal break profile assembly process.
Positioning
The aluminum profile is positioned automatically for processing.
Knurling
Inner grooves are knurled into a toothed surface with controlled depth.
Strip Insertion
PA66 polyamide strip is inserted continuously into both prepared grooves.
Why Knurling Matters
Knurling prepares the aluminum profile groove before strip insertion. The toothed surface improves the mechanical engagement between the aluminum profile and the polyamide thermal barrier strip during the following rolling and crimping process.
For manufacturers producing different thermal break profiles, stable knurling depth and positioning are important for maintaining consistent assembly quality.
Groove designs the machine supports. Send your cross-section drawings for tooling confirmation.

FAQ
What does a CNC knurling and strip insertion machine do?
It knurls the inner grooves of aluminum profiles and inserts PA66 polyamide thermal barrier strips before the rolling and crimping process.
What type of profiles can the machine process?
It is designed for thermal break aluminum profiles. The machine configuration can be adjusted according to profile dimensions and groove design.
What type of thermal barrier strips can be inserted?
The machine is mainly used with PA66 polyamide thermal barrier strips for thermal break aluminum profiles.
Can the machine process different profile designs?
Yes. Processing settings and machine configuration can be adjusted according to different profile designs and production requirements.
Can it be connected to a complete production line?
Yes. The knurling and strip insertion machine can be combined with rolling and crimping equipment and conveying systems for a complete thermal break profile assembly line.
