In modern construction and manufacturing, the demand for metal edge strips, decorative profiles and structural connectors continues to grow. A high-performance trim roll forming machine can form galvanized steel, color-coated steel, aluminum-magnesium-manganese alloy and other metal coils into precision profiles of various cross-section shapes at one time through multi-channel progressive roller pressing process. As a core product in the field of roll forming machine, trim roll forming machine is widely used in many scenarios such as roof waterproofing, wall enclosure system, door and window frame, interior decoration lines, etc., providing high-efficiency, stable and high-precision automatic for metal building materials manufacturers.

Product Process

1.Decoiler： When production starts, the operator lifts the metal coil to the winding machine, and the inner diameter of the coil is fixed by a hydraulic or mechanical tightening mechanism. The decoiler ensures the stability of the strip tension through servo-driven active winding, avoids loose winding, deviation or surface scratches during the feeding process, and provides a flat and continuous strip supply for subsequent forming.

2.Feeding leveling system：After the coil is unfolded, it first enters the leveling mechanism, and the strip is repeatedly leveled through multiple sets of leveling rollers up and down to eliminate the inherent forming residue and plate defects of the coil.

3.Roller：This is the core milestone of the production process of trim roll forming machine. The metal strip is formed through the roller in turn. Each roller only applies a small and controllable forming deformation to the material, and the strip is gradually bent into the required cross-section at room temperature. Due to the uniform distribution of deformation, the molding process almost does not produce rebound and processing hardening residues. The straightness, angular accuracy and surface finish of the finished profile can be fully guaranteed, and there will be no scratches or plating peeling off.

4.Hydraulic shearing system：The formed continuous profile enters the cutting workstation, and the hydraulic shear or servo flying saw automatically completes the cutting according to the preset length. The servo flying saw can move synchronously with the profile to achieve non-stop online cutting. The incision is flat and burr-free, and the length error can be controlled within ±1 mm; the quantity, interval and cutting head waste of the ruler can be preset in the PLC system to achieve fully automated control.

5.Finished product collection table：The cut-off finished profiles are automatically transported to the receiving area through the discharge table, neatly coded with the stacking device, and waited for packaging and storage. The whole production line only needs 1 to 2 operators to monitor, which greatly saves labor costs.

Core technical characteristics

1.Multi-step gradual تشكيل, stable accuracy

ملكنا trim roll forming machine adopts a progressive forming design. Each roll only applies a small amount of deformation to the metal strip, which effectively avoids material rebound and surface scratches. The forming roller is made of high-quality alloy structural steel through precision processing, overall heat treatment and surface chrome plating. The hardness can reach HRC 58-62, the service life is long, the molding size tolerance can be controlled within ±0.5 mm, and the precision customized model can reach ±0.3 mm.

2. Fully automated PLC control, convenient operation

The trim roll forming machine is equipped with a high-performance PLC control system and a color touch screen human-machine interface. The operator can directly set the production length, production quantity, cutting method and other parameters on the interface. The system is equipped with functions such as automatic counting, ruler cutting, fault self-diagnosis and alarm. The whole process of production can be completed with one click, greatly reducing the dependence on the skill level of operators, and reducing the waste of materials caused by human errors.

3.Multi-material adaptation, flexible application

The trim roll forming machine can be processed including galvanized steel plate, aluminum-zinc steel plate, color-coated steel plate, stainless steel plate, aluminum plate and aluminum-magnesium-manganese alloy plate, etc. By replacing rollers or adjusting roller spacing, the same trim roll forming machine can produce a variety of profiles with different cross-sections, helping customers to cover a wider range of product categories with low equipment input and quickly respond to changes in market orders.

Main application fields

The profile products produced by trim roll forming machine play an important role in many industries:

• Building roof and wall system: The production of waterproof sealing profiles such as roof ridge covers, drip lines, flood boards, wall corner edges, door and window edges, etc. are indispensable supporting components of metal roof and wall enclosure systems.
• Interior decoration and decoration: production of U-shaped grooves, L-shaped corner lines, T-shaped keels, ceiling edge strips, background wall decorative lines, etc., which are widely used in interior decoration projects of commercial spaces, residences and public buildings.
• Doors, windows and curtain wall industry: Produce profiles such as door and window frames, curtain wall sub-frames, pressure strips and sealing grooves to meet the high-precision assembly requirements of building facades.
• Transportation and infrastructure: production of vehicle interior strips, road guardrail accessories, cable bridge cover plates and other industrial profiles.
• Household appliances and furniture manufacturing: production of refrigerator glass strips, furniture edge strips, cabinet decoration lines and other precision small profiles.
