Window Frame Roll Forming Machine

Hangzhou IUWON Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of window frame roll forming machine in China. With abundant experience, we warmly welcome you to buy custom made window frame roll forming machine from our factory. Good service and reasonable price are available.

Profile Engineering & Dimensional Control

A window frame is typically composed of several functional sections rather than a single flat bend. Depending on the system design, the profile may include glass-retaining edges, seal channels, screw flanges, reinforcing cavities, drainage paths, and interlocking sections.

The forming rolls are arranged so that these features are created progressively. Early stations establish the basic profile width, while subsequent stations develop smaller bends and functional edges. Final guide rollers correct the profile position before cutting, helping reduce twisting and dimensional variation.

The roller tooling can be manufactured according to a supplied CAD drawing or physical profile sample. Different tooling sets can be prepared for frame, sash, mullion, reinforcement, track, and other related profiles.

Technical Parameters

Built for Profiles with Functional Channels and Reinforcement

Window frame profiles often need internal cavities or channels to provide rigidity without unnecessarily increasing material consumption. These sections can be produced by carefully controlling the bending sequence and roller clearances.

For heavier steel profiles, the forming unit can use a reinforced machine base and higher-capacity transmission system. For thinner coated materials, the roller geometry and guide arrangement can be optimized to minimize scratches, edge distortion, and coating damage.

Additional processing can also be incorporated when the profile requires holes or slots for screws, drainage, locks, or assembly connections. Depending on the production sequence, punching may be carried out before roll forming or after the profile has been formed.

Machine Configuration

Window & Door System Applications

The finished profiles can be used in steel and metal window systems for residential buildings, commercial properties, industrial facilities, warehouses, workshops, and other construction projects. Different profile sections can serve different functions within the same window system.

Common production applications include:

Window frame profiles

Window sash profiles

Door frame sections

Mullion and transom profiles

Steel reinforcement sections

Sliding window tracks

Glass-retaining profiles

Corner and connection profiles

For a customized line, the profile drawing is the primary basis for roller design. The required material grade, thickness range, profile dimensions, punching pattern, cutting length, and production speed are then used to determine the forming stations, tooling dimensions, drive capacity, and auxiliary equipment.

A complete production solution can therefore be configured for either a single high-volume profile or several interchangeable profiles. When multiple sections are required, dedicated tooling sets can be supplied so that each profile retains its designed geometry rather than relying on excessive manual adjustment during production.
