Zhongtuo Steel Window Frame Profile Roll Forming Machine Metal Door Lame Roll Former

The Steel Window Frame Profile Roll Forming Machine Metal Door Lame Roll Former from ZHONGTUO is designed to produce accurate steel profiles for window frames, door frames, and related architectural framing systems. By continuously feeding galvanized steel through a series of precision forming rollers, the machine creates stable profiles with consistent dimensions and a smooth finished surface.

Unlike conventional bending equipment, this Steel Window Frame Roll Forming Machine performs continuous forming, allowing manufacturers to produce long sections efficiently and then cut them to the required length. In addition, ZHONGTUO can customize the roller tooling, punching system, cutting unit, and control configuration according to the customer’s profile drawing.

Steel Window and Door Frame Profile Forming

Steel window and door frames require accurate dimensions because even small profile deviations can affect installation and the final appearance. The ZHONGTUO roll forming system progressively shapes the metal strip through multiple roller stations. Consequently, each forming stage performs a controlled part of the bending process rather than forcing the entire profile into shape at once.

The reference machine is suitable for 0.4–0.8 mm galvanized steel, while other material thicknesses can be evaluated according to the profile structure and production requirements. The rollers use GCr12 material with heat and surface treatment, while the forming shafts use 45# steel to provide stable support during continuous operation.

Manufacturers can use the machine to produce different window and door frame sections, including customized profiles for residential, commercial, industrial, and interior construction projects. If you already have a profile drawing, ZHONGTUO engineers can design the forming stations around your required dimensions.

Metal Door Lame Roll Former with Flexible Profiles

The Metal Door Lame Roll Former provides a continuous solution for manufacturers that need to produce customized metal door frame sections. Instead of manually bending each section, the operator feeds the steel coil into the line and allows the forming stations to progressively create the required profile.

Depending on the application, the tooling can be developed for single-rebate, double-rebate, square-bend, split, flush-finish, drywall, shadow-line, mullion, transom, and other customized door frame profiles.

This flexibility also allows manufacturers to serve different construction markets without relying entirely on separate manual forming processes. Furthermore, when several related profiles are required, ZHONGTUO can evaluate a multi-size or multi-profile configuration based on the customer’s drawings.

Common profile applications include:

• Steel window frame profiles
• Metal door frame profiles
• Single rebate door frames
• Double rebate door frames
• Square bend door frames
• Split door frames
• Flush finish door frames
• Drywall door frames
• Mullion and transom profiles
• Customized architectural framing profiles

Automatic Punching, Forming and Cutting

A complete Window Door Frame Roll Forming Machine can integrate several production processes into one line. First, the decoiler supplies the coil to the feeding and guiding system. The material then enters the forming section, where multiple roller stations gradually shape the strip.

For door frame applications that require installation holes, ZHONGTUO can add an automatic punching system. The punching unit can be configured for hinge holes, lock openings, handle positions, or other specified patterns. The punching layout can also be designed for left-hand and right-hand door configurations.

After the forming process, the hydraulic cutting system automatically cuts the finished profile according to the programmed length. Therefore, manufacturers can reduce secondary cutting operations and maintain more consistent finished dimensions.

The PLC control system allows operators to set production quantity, cutting length, and machine speed through the touch screen. At the same time, the encoder provides length feedback to support accurate automatic cutting.

Technical Specifications

The specifications above represent a reference configuration. ZHONGTUO can customize the machine according to the required profile, material thickness, production speed, punching pattern, cutting length, and electrical standard.

Durable Machine Structure and Control System

Stable machine construction directly affects the accuracy of a roll formed profile. For this reason, the ZHONGTUO Steel Window Frame Profile Roll Forming Machine uses a rigid welded steel base and vertical forming structure to support the forming stations.

The forming shafts use 45# steel, while the GCr12 rollers receive appropriate heat and surface treatment. In addition, the gear transmission system synchronizes the forming rollers and supports continuous production.

The electrical system combines a Delta PLC and touch screen with an Omron encoder and Schneider low-voltage components. Operators can enter production orders, adjust the forming speed, and set the required cutting length through the control panel.

The hydraulic cutting system uses a dedicated hydraulic power unit. The hydraulic components and electrical wiring can be clearly identified during installation, which makes commissioning and future maintenance more convenient.

Customized Steel Window Frame Manufacturing Solution

Every window and door frame profile has its own dimensions and forming requirements. Therefore, ZHONGTUO does not rely on one fixed roller design for every project.

Customers can provide a CAD profile drawing, finished sample, or detailed profile dimensions. Our engineers can then evaluate the material thickness, profile geometry, forming sequence, punching requirements, and required production speed.

Based on this information, ZHONGTUO can develop a customized Steel Window Frame Roll Forming Machine for the customer’s production line. The machine can also be configured for related metal door frame applications when the profile is suitable for roll forming.

For manufacturers producing architectural metal framing, this continuous production method offers several practical benefits. It reduces repeated manual bending, improves profile consistency, integrates cutting and optional punching, and provides a more efficient workflow for long-run production.

Whether your application involves steel window frame profiles, metal door frames, galvanized frame sections, or customized architectural profiles, ZHONGTUO can develop the forming equipment around your actual product requirements.

FAQ

1. What material can this Steel Window Frame Profile Roll Forming Machine process?
The reference configuration is designed for galvanized steel and compatible carbon steel. The standard material thickness is 0.4–0.8 mm, while other thicknesses can be evaluated according to the profile.

2. What is a Metal Door Lame Roll Former used for?
A Metal Door Lame Roll Former continuously shapes metal strip into door frame and related architectural profiles. The final profile depends on the customer’s roller tooling and technical drawing.

3. Can the machine produce both window and door frame profiles?
Yes. ZHONGTUO can develop customized tooling for suitable steel window frame and metal door frame profiles. The actual profile range depends on the required dimensions and forming configuration.

4. Can hinge and lock holes be punched automatically?
Yes. An optional punching system can be integrated to produce hinge holes, lock openings, handle positions, and other customized holes during production.

5. Can ZHONGTUO manufacture the machine according to our profile drawing?
Yes. Customers can provide a CAD drawing, profile drawing, or finished sample. Our engineers will use the profile information to develop the appropriate forming and punching solution.

6. What is the forming speed?
The reference machine operates at approximately 0–12 m/min. The actual speed depends on material thickness, profile complexity, punching requirements, and the final machine configuration.
