The Trend Toward Automation in Aluminum Windows and Doors

Article from “De Schrijnwerk”

The production of PVC windows and doors has been largely automated for quite some time at most joineries. In contrast, automation in aluminum window and door production has generally been limited to sawing and machining centers. However, it is clear that even after these production steps, there are numerous opportunities to further optimize and automate the remaining production processes.

Automated Corner Pressing for Higher Productivity

We can significantly increase productivity with a CNC-controlled 4-head corner press. Each window is assigned a specific barcode, which, once scanned, automatically adjusts the feed table to the correct dimensions. After assembling the element, the operator places it on the feed table, and the element is then automatically transported to the corner press.

The window is transported into the press, where the four press heads simultaneously press all four corners. A key feature is that this process is profile-independent. Two knives are CNC-configured for height and depth, allowing different profile types to be pressed consecutively using the same tools. The operator no longer needs to manually change press knives during a profile change.

While the machine presses automatically, the operator can already prepare the next element, as no adjustments are required. After pressing, the element is transported to an automatic output table, where the corners are exposed, allowing for easy cleaning.

Automatic Gasket Insertion

Inserting gaskets is a very labor-intensive and time-consuming task that can be perfectly automated. In addition to inserting gaskets into profiles, Tryma also offers a solution for automatically inserting gaskets continuously into already assembled windows and doors. A typical setup consists of a CNC-controlled 4-head corner press combined with an automatic gasket insertion machine for the pressed frames and sashes. The gaskets are inserted continuously around the perimeter and, if necessary, are processed in the corners.

Robotic Hardware Assembly

The assembly of hardware components can be automated using a robot. Elements are automatically fed via a vertical roller conveyor. The profile on which the hardware is to be mounted is first automatically clamped. The robot then performs the necessary operations, placing the hardware in the correct position and fastening it with screws.

A storage system is provided for the various hardware components. The hardware can be replenished from the back of the storage system without stopping the installation. Once all hardware components have been mounted, the finished element is transported to an automatic vertical roller conveyor combined with a buffering and sorting system.

Buffer and Sorting System

In a window and door factory, most time is lost on “handling”—picking up, transporting, turning, and storing products. Many companies face a shortage of staff, making it preferable to dedicate this time to actual production.

Increasingly, higher demands are also being placed on employee ergonomics. Colleagues often help each other lift products, which takes time that could be better spent elsewhere.

Tryma provides a fully automated buffering system that allows frames and sashes to be moved automatically throughout the factory. In addition, we optimize the workstations for the tasks performed there. With extensive experience, Tryma can assist you in developing a tailored plan to meet your specific needs.
