Better Quality Through Pressing, Not Nailing
Article from "De Schrijnwerk"
We often get asked by customers what the best method is: pressing or nailing. Here’s our advice.
Jasper Neirynck, Managing Director of Tryma, recommends pressing over the more commonly chosen nailing. “From a quality perspective, pressing the corners is always preferable. A corner press machine uses clamps to securely hold the corner in place before it is pressed. When the machine is properly set up, the result is a perfectly flat corner that doesn’t open up.”
What’s the Difference Between Pressing and Nailing?
With nailing, a hole is drilled, and a pin is inserted to fix the corner piece. Pressing, on the other hand, deforms the aluminum with a pressing tool, securing the corner firmly.
The main disadvantage of pressing is the setup time required for a corner press. Traditional corner presses need to be manually adjusted for each profile type. This setup can take considerable time, which is why nailing is often preferred for single units or small series, despite its negative impact on quality.
For window frames, CNC-controlled corner presses are available. The major advantage of these machines is that the tools automatically adjust for each profile, both in terms of tool position and pressing depth.
According to Jasper, the 4-head CNC corner press avoids the common drawbacks. “This advanced press clamps the entire window or door frame before pressing, ensuring perfect squareness and the best possible corner connection. Additionally, a CNC 4-head corner press significantly increases productivity and workflow efficiency.”
CNC corner presses are available in 1-head, 2-head, and 4-head configurations. For more information about these machines, please contact us or view the videos on our website.
