Dual-Motor Thermal Break Knurling Strip Insertion Machine

Features & Advantages

Product Summary

The Dual-Motor Thermal Break Knurling & Strip Inserting Machine integrates precision knurling and PA66 strip insertion into a single, high-efficiency process. Independent drive heads ensure synchronized operation and accurate profile positioning, while variable frequency control delivers consistent feed rates up to 70m/min. Engineered for aluminum window, door, and curtain wall manufacturers who demand high-shear strength thermal break profiles and reliable production output.

High-Precision Knurling Technology: Imported high-hardness knurling rollers ensure uniform and clear profile tooth patterns. The tight combination of thermal break strip and aluminum profile improves overall structural tightness and thermal insulation performance of finished products.

Automatic Integrated Operation: Realizes automatic feeding, knurling, positioning and strip inserting. Greatly reduces manual intervention, improves production efficiency and lowers labor operation errors.

Wide Compatibility: Supports processing of various specifications of aluminum thermal break profiles and PA66 thermal insulation strips. Adjustable processing parameters to meet customized production demands of different profile sizes.

Stable & Durable Structure: Thickened industrial machine body and anti-vibration structure design reduce operation vibration. Core components adopt wear-resistant materials, extending service life and reducing later maintenance costs.

Safe & Energy-Saving: Equipped with emergency stop protection, overload protection and anti-pinch safety devices. Optimized motor operation program reduces idle power consumption, achieving energy-saving and efficient production.

Technical Parameters

Working Principle

The machine adopts dual-motor synchronous linkage working mode. One motor controls the precision knurling roller to perform uniform tooth rolling on the aluminum profile groove, forming standard anti-slip tooth grooves. The other motor drives the automatic feeding and positioning mechanism to accurately deliver the PA66 thermal break strip into the profile groove. Through mechanical pressing and fitting, the thermal strip and aluminum profile are tightly combined as a whole. The whole process realizes one-time forming of knurling and strip inserting, ensuring stable product quality and high processing consistency.we are one manufacturer for OEM and ODM

Key Features

Dual-Motor Independent Drive — Separate motors control knurling and strip insertion heads, allowing independent adjustment of speed, pressure, and position for optimal process synchronization.

Integrated Knurling & Insertion — One machine performs both critical steps: precision tooth-rolling on the profile groove and accurate PA66 strip feeding, eliminating the need for two separate machines.

Variable Frequency Feed Control — Stepless speed adjustment from 0–70m/min ensures consistent feed rates across different profile sizes and thermal break strip specifications.

CNC-Adjustable Head Positioning — Electric adjustment of head height and horizontal position simplifies profile changeovers and reduces setup time between production runs.

Pneumatic Profile Clamping — Fast-acting pneumatic clamps secure the aluminum profile during processing, preventing slippage and ensuring repeatable accuracy.

High-Shear Strength Knurling — Precision knurling wheels create consistent micro-tooth patterns in the profile groove, maximizing mechanical bite and shear strength of the thermal break assembly.

User-Friendly Control Interface — Intuitive digital control panel with preset programs for common profile types. Operators can store and recall parameters for fast changeovers.

Heavy-Duty Frame Construction — Rigid welded steel frame and industrial-grade components ensure long-term stability and reliable performance in multi-shift production environments.

FAQ

Q: What is the difference between single-motor and dual-motor knurling & inserting machines?

A: Single-motor machines drive both knurling and insertion heads from one motor, limiting independent adjustment. Dual-motor machines provide separate control over each process, allowing optimal synchronization and better results across different profile shapes and strip types.

Q: What types of thermal break strips can this machine handle?

A: It is designed for PA66 GF25 strips (the industry standard), as well as PA6 and fiberglass-reinforced strips. Custom strip widths and profiles can be accommodated—please contact us with your specifications.

Q: How precise is the knurling process?

A: The machine creates consistent micro-tooth patterns with depth and spacing controlled by CNC-adjusted head positions. This ensures high-shear strength and reliable thermal break performance.

Q: How long does it take to change over to a different profile?

A: With CNC head positioning and stored parameters, most profile changeovers can be completed in 10–15 minutes by a trained operator.

Q: What after-sales support do you provide?

A: We offer installation guidance, operation training, spare parts supply, and remote technical support. On-site service is available depending on location.
