Innovation in Metal Door Frame Machine Technology: Width-Adjustable Solutions with Online Punching
In the fast-evolving world of metal forming machinery, adaptability and automation are no longer optional—they are essential. At Zhongtuo Roll Forming Machinery, we continue to lead the industry by introducing intelligent innovations that redefine production efficiency and product flexibility. Our latest advancement in metal door frame machine technology brings a game-changing feature to manufacturers: fully width-adjustable door frame production, controlled by PLC with online hinge hole punching capability.
This breakthrough allows manufacturers to switch between different door frame widths without changing the tooling, significantly reducing downtime and increasing overall productivity.
What Is a Metal Door Frame Machine?
A metal door frame machine is a specialized roll forming system used to produce high-strength, precisely profiled metal door frames for residential, commercial, and industrial applications. These frames serve as the structural skeleton around doors and must be accurate, cleanly cut, and punched to exact specifications.
Traditional metal door frame machines are often designed for fixed-width production, meaning any change in size requires manual tooling adjustments or entirely different molds. Our upgraded system eliminates this constraint through advanced PLC (Programmable Logic Controller) automation.
Key Features of the Width-Adjustable Door Frame Machine
1. PLC-Controlled Width Adjustability
The most significant innovation is the PLC-controlled width adjustment. By integrating a programmable system, operators can now change the frame width directly from the control panel. This eliminates the need for manual recalibration or physical repositioning of tooling components.
This feature is especially beneficial for manufacturers who serve multiple clients or projects requiring door frames of varying dimensions. It enhances production flexibility, shortens lead times, and reduces human error during setup.
2. Online Hinge Hole Punching System
Another standout feature is the online punching system for hinge holes and lock slots. Punching is carried out automatically while the sheet moves through the roll forming process—no need for offline or secondary punching operations. This not only saves time but also ensures perfect alignment between formed profiles and punch locations.
Our machines can also be customized for knock-down type hole punching or fixed-size punching, depending on the production requirements. The video demonstration attached to this release shows the machine operating in a fixed-size, non-knockdown punching configuration, delivering high consistency and precision in every piece.
3. Heavy-Duty Construction & Precision Engineering
Built for stability and longevity, the metal door frame machine features a solid steel frame, precision-ground rollers, and high-quality motors. These components ensure smooth operation and accurate profile shaping, even during continuous high-speed production.
Our engineers use advanced CAD/CAM modeling and precision machining tools to design and manufacture each forming roller, guaranteeing a perfect match to your door frame design.
