With abundant experience, we warmly welcome you to buy high quality door frame roll forming machine from our factory. Good service and reasonable price are available.
Multi-Stage Gradual Forming Technology
Our system utilizes a 18 to 22-station forming process that bends the metal strip incrementally. This "gradual stress" approach ensures the structural integrity of the metal is maintained, preventing cracking or warping even when producing complex profiles. The rollers are CNC-machined from Cr12MoV tool steel, heat-treated to HRC 58-62, and plated with 0.05mm hard chrome for maximum longevity.
Precision Hydraulic Pre-Punching
Efficiency is built into the line with an integrated multi-cylinder punching system. Before the profile is formed, the machine automatically punches holes for hinges, lock sets, and mitered corners.
- Spot-Welding Free: Pre-cut 45-degree miters allow for an accurate fit without the need for extensive manual grinding.
- Punch Material: SDK11 high-carbon steel dies ensure over 300,000 cycles of clean, burr-free holes.
Smart PLC Automation & Remote Diagnostics
Powered by a Siemens or Delta PLC control system, the machine offers a fully digitized production experience.
Touchscreen HMI: Operators can input length, quantity, and hole spacing in seconds.
Precision Measurement: A high-resolution rotary encoder guarantees a length tolerance of within ±0.5mm to ±1.0mm.
IoT Integration: Modern units support remote monitoring, allowing our engineers to provide software updates or diagnostics via the cloud.
Integrated Hydraulic "Stop-Cut" System
The final stage features a hydraulic guillotine shear that matches the exact cross-section of your door frame. This "Stop-to-Cut" mechanism ensures the profile ends are perfectly vertical and square, which is critical for the easy assembly of vertical and horizontal frame headers on-site.
Recommended Industrial Models
This versatile model is ideal for residential and business construction, capable of forming multi-width profiles ranging from 120mm to 250mm.
A high-end CNC-controlled unit specifically designed for hollow metal door frames, prioritizing speed and precision for large-scale manufacturing.
This premium automated line features gear and bearing drives for smoother operation and higher durability during continuous 24/7 production cycles.
FAQ
Q: Can one machine make both single and double-rebate frames?
A: Yes. While standard machines are fixed, we can design the rollers with removable sleeves or a cassette system that allows you to change between single and double-rebate profiles within about an hour.
Q: What is the typical production speed for a door frame?
A: Most industrial machines operate at 10–25 meters per minute. For a standard 2-meter vertical frame, the output is approximately 3 to 6 pieces per minute, depending on the complexity of the punching requirements.
Q: Is it possible to produce fire-rated frames on this machine?
A: Absolutely. By using thicker materials (1.5mm–2.0mm) and specific profile designs, these machines are widely used to manufacture fire-resistant metal frames that meet international safety standards.
Q: How do you ensure the mitered corners fit perfectly?
A: The machine uses a servo-driven pre-punching unit that cuts the 45-degree notches with extreme precision before the profile is rolled. This ensures that when the vertical and horizontal pieces are joined, the corner is tight and square.
Q: What power supply is required for this equipment?
A: Standard configurations are 380V/50Hz/3-Phase, but we can customize the motors and PLC to match your local voltage (e.g., 220V, 415V, or 460V) to ensure plug-and-play installation.
