Steel Door Frame Roll Forming Machine (Metal Door Jamb & Casing Production Line)

Industrial high-precision cold roll forming production line engineered for manufacturing commercial steel door frames, fire-rated door jambs, security door casings, and architectural window buck framing profiles. Built for commercial interior fabricators, steel door manufacturing plants, and architectural hardware suppliers. Features heavy-duty structural steel foundation, premium GCr12MoV vacuum-quenched alloy tool steel roller dies, solid 45# heat-treated tempered shafts, high-precision hydraulic 45°/90° miter profile track cutting unit, and imported PLC digital touchscreen automation.

High-Precision Complex Asymmetrical Geometry: Expertly roll forms multi-bend intricate door jamb profiles with integral weatherstrip grooves, door stop rebates, and plaster flanges with ±0.5mm cross-sectional accuracy.
GCr12MoV Vacuum Quenched Roller Dies: Precision CNC-machined forming rollers forged from GCr12MoV alloy tool steel (HRC 58-62) prevent profile galling, surface scratching, and premature die wear across millions of meters.
Hydraulic Track Profile Miter Cutting: High-tonnage hydraulic track shear station equipped with Cr12 profile-contoured blades delivers clean, distortion-free 45° and 90° miter cuts ready for seamless jobsite corner interlocking and welding.
Solid 45# Shafts & Heavy-Duty Machine Bed: Robust 6,500kg normalized steel bed with individually numbered roll forming stands guarantees structural alignment, zero deflection, and low vibration during high-speed rolling.
High Productivity up to 30-50 m/min: Driven by a 15kW industrial power motor with closed-loop optical rotary encoder length feedback (±1mm accuracy) and multi-language touchscreen order scheduling.

Product Overview

The Steel Door Frame Roll Forming Machine is an essential production line for modern architectural construction, commercial office fit-outs, fire door engineering, and hospitality facility manufacturing. Compared to labor-intensive manual press brake bending, this continuous roll forming system dramatically slashes production time, guarantees micro-millimeter tolerance consistency across left/right jambs and header sections, and minimizes steel scrap.

Accommodating galvanized steel coils (GI), cold-rolled carbon steel (CRC), and prepainted steel (PPGI) with sheet thicknesses ranging from 0.4mm to 0.8mm (customizable up to 1.5mm/2.0mm for heavy bullet-proof/fire-rated specifications). The finished door frames feature crisp 90° corner folds, uniform rebate depths for rubber sealing gaskets, and pre-engineered mortise hinge recesses.

Key Technical Features

Multi-Stage Progressive Cold Rolling: Incorporates 16 to 22 forming passes with intermediate side-roll guide stands to gently form tight bends and multiple rebate lips without stress concentration or edge wave.
Wear-Resistant GCr12MoV Rollers: Hardened to HRC 58-62 through precision vacuum heat treatment and mirror polished, preserving the factory finish on pre-painted and galvanized coil stock.
Integrated Hydraulic Profile Shearing: Track-following hydraulic shear with full-perimeter Cr12 die blades prevents flange collapse, eliminating secondary deburring or saw cutting operations.
Heavy Welded Monoblock Chassis: Normalized heavy structural steel chassis with CNC-planed mounting pads maintains perfect axial alignment across all forming stations over decades of industrial use.
Intelligent Digital Control Desk: Multi-language PLC touch terminal allows rapid setup of production batches, cut lengths, quantity counts, and automated acceleration/deceleration curves.

Precision Numbered Forming Stands

Forming complex multi-step door frames requires precise angle distribution across progressive rolling stations. Each stand is clearly numbered and engineered to deliver uniform metal deformation:

Individually Numbered Stations: Stand numbers (1, 2, 3...) facilitate quick tooling calibration, roller clearance adjustment, and operator maintenance.
Side-Roll Calibrating Units: Vertical side-roll passes correct profile springback, ensuring vertical squareness between the jamb face and door stop.
Dual Lock-Nut Adjustment: Micrometer threaded adjusters provide micro-level roller nip setting to adapt across various metal thicknesses.

Broad Architectural Applications

Metal door frames produced on this line serve critical structural framing roles across global commercial and residential sectors:

Commercial Office & Hospital Doors: Fire-resistant and acoustic door frames for high-traffic public institutions.
Residential Security Entrance Doors: Heavy-gauge anti-theft security door jambs with multi-locking point cutouts.
Prefabricated Modular Buildings: Standardized knock-down (KD) door frames for rapid site assembly and container shipping.

Frequently Asked Questions (FAQ)

Q1: Can one machine produce different sizes of door frames?

A: Yes. With quick-change spacer sleeves or split-roll design, the wall throat depth and rebate width can be adjusted to cover multiple standard door jamb specifications.

Q2: What is the benefit of GCr12MoV roller material?

A: GCr12MoV is a premium alloy tool steel with superior toughness and hardness (HRC 58-62) that completely prevents galling and scratching when forming pre-painted or galvanized coil.

Q3: How are the 45-degree miter corner joints cut?

A: The line integrates an automatic hydraulic track shear equipped with combined 45° and 90° profile cut-off dies, providing seamless corner mitering for rapid jobsite frame assembly.

Q4: Can the machine operating voltage be configured for our factory?

A: Yes. Electrical systems and motors can be custom wired for 220V, 380V, 415V, or 440V (50Hz / 60Hz, 3-Phase).

Q5: What factory testing and warranty are provided?

A: We provide complete outgoing test-run videos, CE compliance documentation, formal inspection reports, and a 1-year warranty with lifetime technical support.
