Máquina perfiladora de marcos de puertas de acero

A máquina perfiladora de marcos de puertas produces steel door frames in custom sizes. It punches notches, hinge holes, and lock cutouts in one continuous line. The finished profile folds into a complete door frame.

This door frame roll former handles galvanized steel from 0.8 mm to 2.0 mm thick. With 22 forming stations and servo-controlled punching, it delivers consistent output at 15 to 20 meters per minute.

What a Door Frame Roll Forming Machine Does

A máquina perfiladora de marcos de puertas takes flat steel coil and turns it into finished door frame profiles. The line uncoils, levels, punches, forms, and cuts — all in one pass.

This isn’t just a bending machine. The punch unit cuts the miter notches that let you fold the frame at 90-degree corners. It also punches mounting holes, hinge slots, and lock prep. Everything the installer needs is already in the profile when it comes off the line.

Compared to traditional press-brake fabrication, a door frame roll former cuts labor by 60% or more. One operator runs the whole line from a touch screen.

Steel Door Frame Types

Two main door frame profiles dominate the market:

Single Rebate Door Frame. The door mounts on one side only. Common in residential and light commercial work. Thinner gauge steel, simpler tooling.
Double Rebate Door Frame. Doors can mount on either side. Standard for commercial, institutional, and fire-rated openings. Heavier gauge, wider profile — and the door frame machine needs adjustable tooling to handle both rebate depths.

Steel door frames beat timber on cost, speed, and durability. They install during framing or as retrofits. Galvanized coating means no rust, no warping, no callbacks. That’s why specifiers across Australia, the Middle East, and Africa keep choosing steel over wood — see the HMMA hollow metal standards for performance benchmarks.

Door Frame Corner Joints: 6 Methods

How the frame corners connect matters. Different markets need different joints. The self-joint (mitered fold) is the most advanced — no welding, no fasteners.

Butted knocked-down joint — basic, weld on site
Welded joint — shop-welded, ships as a rigid frame
Mitered joint — 45-degree cut, welded or screwed
Spot-welded joint — tack welds, assembles on site
Soldadura a inglete — full miter with continuous weld
Self-joint (mitered fold) — punch notches during roll forming, fold and lock on site. No welder needed. This is the standard for high-volume commercial door frame production.

The self-joint design requires precise notch geometry. A máquina perfiladora de marcos de puertas with servo punch control hits tolerances within ±0.3 mm, which manual fabrication can’t match.

Why This Door Frame Machine Over Manual Fabrication

A standalone press brake needs 5-6 separate operations per frame: shear, notch, punch hinges, punch lock, bend, weld. A máquina perfiladora de marcos de puertas does all this in one line.

Factor	Máquina perfiladora de marcos de puertas	Manual Press Brake
Operations	1 continuous line	5-6 separate stations
Output speed	15-20 m/min (6-8 frames/min)	1-2 frames/min
Mano de obra	1 operador	3-4 workers
Tolerancia	±0.3 mm (servo punch)	±1.5 mm (manual setup)
Material yield	98%+ (coil-fed, near-zero drop-off)	88-92% (sheet offcuts)
Self-joint ready	In-line notching, fold on site	Requires separate notching step
Changeover	30 min (die swap + stand adjust)	60-90 min (multiple tool changes)
Annual breakeven	~15,000 frames/year	N/A (labor scales linearly)
Per-frame cost at scale	$0.80-1.20	$3.50-5.00

Above 15,000-20,000 frames per year, the door frame roll former pays for itself. Per-unit cost drops 40-55% at scale compared to manual fabrication, according to Steel Door Institute benchmarks.

Preguntas frecuentes

What thickness can this door frame roll forming machine handle?

0.8 mm to 2.0 mm galvanized steel. The 22-station forming section and 75 mm shafts handle the full gauge range without deflection. For material above 2.0 mm, contact us for a custom configuration.

Can the machine switch between single and double rebate frames?

Yes. The roller tooling adjusts for both profiles. Changeover takes about 30 minutes — swap the punch die set and adjust the forming stands. Many customers run both profiles on the same door frame roll former.

What's the difference between hydraulic punch and servo punch?

Hydraulic punch uses a central power unit (11 kW, 20 MPa in our spec). Servo punch drives each axis independently with a Yaskawa motor. Servo is faster on position changes and uses less energy. Our máquina perfiladora de marcos de puertas uses servo for the notching and hydraulic for the heavier hole punching — best of both.

How fast does the line run?

15 to 20 meters per minute of finished profile. Actual output depends on frame size. A standard 2.1-meter door frame takes roughly 8-10 seconds per piece.

What power supply does it need?

Configured to client standard — 380V/50Hz, 440V/60Hz, or other. The PLC and inverter handle voltage conversion internally.

Is installation and training included?

Yes. We send an engineer for on-site setup and operator training. The door frame machine ships with English manuals, wiring diagrams, and a spare parts list. Remote support is available after commissioning.

How does this compare to buying from a local fabricator?

Local sheet metal shops use press brakes and turret punches. Per-frame labor is 3-5x higher. A máquina perfiladora de marcos de puertas pays for itself at roughly 15,000-20,000 frames per year. Above that volume, the margin difference is decisive. Steel Door Institute data shows automated roll forming cutting per-unit costs by 40-55% at scale.
