Top 6 Solar Panel Frame Roll Forming Machines For PV Module Manufacturers(Listed in No Particular Order)

The aluminum frame around a photovoltaic module is more than a protective edge. It provides mechanical support for the glass and module laminate, maintains dimensional stability during transportation and installation, and creates the interface between the module and the mounting system.

As PV module manufacturers increase production capacity, the frame manufacturing process becomes an important part of overall module assembly efficiency. Traditional cutting, punching, bending, and manual assembly can involve multiple independent operations. A dedicated solar panel frame roll forming machine can combine continuous profile forming with cutting and other downstream processes, creating a more consistent production route for high-volume PV frame components.

However, buyers should make an important distinction before selecting equipment: a machine for solar mounting brackets is not necessarily a machine for PV module frames. Mounting structures are designed to support modules on roofs or ground structures, while module frames are directly integrated with the photovoltaic panel itself. The profile geometry, dimensional tolerance, material, joining method, and finishing requirements can therefore be substantially different.

The following six manufacturers are listed in no particular order. They represent different equipment approaches, from dedicated solar panel frame forming equipment to broader roll forming manufacturers that can engineer customized profile lines.

Hangzhou IUWON Technology Co., Ltd. is a China-based roll forming equipment manufacturer established in 2003, with more than 20 years of industry experience. Its current equipment portfolio includes solar mounting machinery, purlin machines, roofing equipment, cable tray systems, and customized profile roll forming solutions.

For PV module manufacturers, IUWON's relevant equipment includes its solar panel frame and strut roll forming machine, which is designed around the production of solar frame sections, strut channels, mounting rails, and customized profiles. The company states that its solar frame equipment can process galvanized steel, aluminum, and coated materials, with a typical material thickness range of approximately 1.0–3.0 mm depending on configuration.

One of the more important aspects of IUWON's approach is that the equipment can be configured around the customer's profile rather than relying exclusively on a fixed machine specification.

A PV module manufacturer may need a frame with:

A specific flange height

A customized glass-supporting channel

Drainage or ventilation features

Pre-punched holes

Specific corner-joining geometry

A particular aluminum or steel grade

Different profile lengths for different module dimensions

The forming rollers therefore need to progressively create the required cross-section without introducing excessive deformation to the material.

IUWON states that its machines can be customized according to profile drawings, material specifications, and production requirements. Its broader solar mounting solution also covers customized PV profiles and integrated punching.

Depending on the frame design, an IUWON production line can be arranged around:

Decoiler → Leveling → Feeding → Punching → Roll Forming → Cutting → Run-Out/Stacking

The exact process changes according to whether holes are required before forming, whether the profile is supplied as straight sections, and how the finished frame is assembled.

For a manufacturer producing multiple module formats, the engineering stage should also determine whether one tooling set can accommodate related profiles or whether separate roller tooling is necessary.

IUWON's broader manufacturing capability includes mechanical fabrication, precision machining, assembly, electrical integration, and testing. The company also states that its engineering team develops equipment according to users' specific technical requirements.

IUWON is particularly relevant when the project requires:

A customized module frame cross-section

Drawing-based roller tooling

Integrated punching and cutting

Different material specifications

Customized production-line layouts

Complete roll forming line integration

Factory testing before shipment

For OEM-oriented PV manufacturers, the ability to develop a line around the actual frame drawing can be more useful than selecting a generic machine based only on the phrase "solar panel frame."

Nantong Reliantt Machinery is one of the more directly relevant suppliers for this category because it specifically publishes a Solar Panel Frame Forming Machine.

According to the company's product information, the machine is designed to manufacture metal solar panel frames and uses a conventional continuous roll forming workflow consisting of an uncoiler, feeding system, forming section, cutting equipment, and run-out table.

The equipment is positioned as an alternative to traditional aluminum frame manufacturing by producing iron or steel frame sections. This can be relevant to PV module manufacturers investigating alternative frame materials or looking for a continuous forming process for steel-based frame components.

The published production flow is:

Decoiler → Feeding → Roll Forming → Cutting → Out Table

This relatively straightforward configuration can be advantageous when the finished frame profile does not require extensive inline punching or secondary processing.

The basic concept is different from a mounting bracket line. The machine's objective is to create the cross-sectional geometry of the module frame itself.

For a PV module factory, the critical evaluation points should therefore include:

Frame cross-section

Material thickness

Material grade

Profile straightness

Cut-length accuracy

Surface protection

Corner connection method

Compatibility with module assembly equipment

A manufacturer considering steel rather than aluminum should also evaluate corrosion protection, thermal expansion, weight, and the mechanical interface between the frame and the PV laminate.

Reliantt's dedicated solar panel frame machine makes it a relevant option for manufacturers specifically investigating metal frame production through continuous roll forming.

Wuxi Sunway Machinery is a Chinese roll forming equipment supplier with a broad portfolio covering construction and solar-related profiles.

Its solar equipment is more strongly associated with photovoltaic mounting and structural components than with a single standardized module-frame machine. However, this broader forming capability can be useful to PV manufacturers that operate vertically integrated production facilities.

The distinction matters because a large solar manufacturer may produce both:

PV Module Frames

and

PV Mounting Components

within the same industrial ecosystem.

A supplier capable of handling different profile geometries can potentially support several production lines rather than only one product.

For a solar frame project, the technical evaluation should focus on the machine's ability to maintain the required cross-sectional geometry throughout continuous production. The forming process should distribute deformation across multiple stations rather than relying on aggressive bending at a limited number of stands.

A PV manufacturer should provide:

Frame profile drawing

Material specification

Thickness range

Coil width

Finished length

Required output

Punching requirements

Cutting tolerance

Surface treatment

Automation requirements

The supplier can then determine the appropriate roller configuration, forming stations, drive system, cutting method, and auxiliary equipment.

This makes Sunway more relevant to manufacturers seeking a custom industrial roll forming solution rather than a simple off-the-shelf frame machine.

KINGREAL is a Chinese manufacturer with more than 20 years of experience in roll forming equipment. Its photovoltaic equipment portfolio includes PV support bracket machines, solar channel machines, and roll forming lines for C, U, Z, Ω, and Sigma structural profiles.

Its strongest relevance to PV module manufacturers is the company's emphasis on customized and automated profile production.

The published PV support bracket line, for example, combines decoiling, leveling, feeding, punching, forming, cutting, and receiving. KINGREAL also offers automatic packaging for certain configurations.

Although these machines are primarily described for PV support structures rather than the aluminum module frame surrounding a panel, the same engineering capabilities can become useful when a manufacturer needs customized steel PV frame or auxiliary profile production.

KINGREAL's photovoltaic equipment can be configured for multiple channel dimensions and structural geometries. Its published solar channel systems include sizes such as 41×21 mm, 41×41 mm, 41×62 mm, and 41×82 mm, while its PV structural equipment can produce C, U, Z, Ω, and Sigma profiles.

For a PV manufacturing group producing both module-support components and structural profiles, this flexibility can be valuable.

The company also states that customers can provide drawings for customized equipment and that different punching arrangements can be incorporated according to production requirements.

PV module manufacturers should not assume that a solar bracket machine can automatically manufacture their module frame.

The frame drawing must be evaluated first.

If the frame is aluminum, the forming characteristics will differ from galvanized steel. If the frame contains complicated grooves, clips, or assembly interfaces, the tooling design may also require a dedicated forming sequence.

KINGREAL is therefore more appropriately considered as a candidate for customized PV profile production, with the final machine configuration determined by the customer's frame design.

Samco Machinery is a Canadian roll forming equipment manufacturer serving industrial profile production applications.

Rather than focusing exclusively on photovoltaic products, Samco's relevance comes from its broader experience in engineered roll forming systems.

For large PV module manufacturers, this can be important because the frame production line may be integrated into a much larger factory automation system.

A high-volume PV manufacturing plant may require the forming machine to communicate with:

Coil handling equipment

Servo feeding systems

Punching systems

Cutting systems

Automated transfer equipment

Stacking units

Packaging equipment

Factory production-control systems

The machine therefore becomes one part of an automated manufacturing cell rather than an isolated piece of equipment.

A customized industrial roll former becomes particularly relevant when:

The customer has a proprietary frame profile

Multiple frame sizes are produced

Production runs continuously

Dimensional consistency is tightly controlled

Inline operations are required

The machine must interface with existing automation

The manufacturer expects long-term production expansion

Samco should consequently be evaluated based on its engineering response to the actual PV frame profile rather than simply comparing nominal forming speed.

For a large PV module producer, process integration can be more important than maximum machine speed. A fast forming machine that requires extensive manual handling may not deliver the same factory-level productivity as a moderately fast line integrated with automated feeding, cutting, transfer, and stacking.

The Bradbury Group is a US-based industrial equipment manufacturer with extensive roll forming and coil-processing capabilities.

Its published equipment portfolio includes panel roll forming lines and purlin roll forming systems, with configurations ranging from relatively simple production equipment to highly automated high-volume systems.

Bradbury is not positioned exclusively as a PV module frame manufacturer. Its relevance to this comparison is its broader industrial roll forming engineering capability.

For PV manufacturers operating at large production volumes, the important question is whether the machine architecture can support the required production environment.

The Bradbury Group states that its roll forming equipment can be configured for different production requirements and levels of automation, including flying and stop-to-cut systems in its panel equipment and automatic changeover capabilities for some purlin lines.

A PV manufacturer considering an industrial supplier such as Bradbury should evaluate:

Frame material and yield strength

Profile complexity

Number of forming stations

Drive configuration

Line speed

Cutting technology

Punching requirements

Changeover time

Automated material handling

Production monitoring

Maintenance access

The principal advantage of this type of supplier is not necessarily a dedicated "PV frame machine" product. Instead, it is the ability to engineer a roll forming system around a demanding industrial production environment.

Selecting the machine should begin with the PV frame itself, not with the machine catalog.

A photovoltaic module frame usually has a relatively complex cross-section because it needs to perform several functions simultaneously:

Hold the glass and laminate

Provide mechanical rigidity

Protect module edges

Provide drainage or clearance

Interface with mounting hardware

Support corner connections

Maintain dimensional consistency

These functions determine the roller tooling.

A typical forming sequence progressively changes the flat strip into the final frame geometry:

Flat Coil → Edge Forming → Sidewall Formation → Flange Formation → Groove Formation → Calibration → Cut-to-Length

The exact sequence depends entirely on the profile.

If the profile contains sharp internal bends, narrow lips, multiple channels, or asymmetric geometry, additional forming passes may be required.

Material selection is one of the first questions a machine supplier will ask.

Aluminum is widely used for PV module frames because of its low density and corrosion resistance. However, aluminum's forming behavior differs from steel, so the roller design and forming strategy need to account for the alloy and temper.

The supplier should evaluate:

Aluminum alloy

Temper condition

Thickness

Surface treatment

Minimum bend radius

Required dimensional tolerance

Steel frames can offer different cost and structural characteristics and can be processed through roll forming when the product design is suitable.

Reliantt, for example, explicitly describes its solar panel frame forming machine as a solution for producing iron frames as an alternative to aluminum material.

For steel frame production, the machine designer needs to consider yield strength, coating condition, thickness, and the required forming radius.

The important point is that a machine should not be selected simply because it is advertised as suitable for aluminum or steel. The exact material specification should be tested against the proposed tooling.

Not every frame requires punching during roll forming.

Some PV frames are cut to length and subsequently machined, while others require holes or slots for mounting, grounding, drainage, or assembly.

If punching is required, the buyer should specify:

Hole diameter

Hole shape

Hole position

Hole-to-hole pitch

Number of holes

Distance from the profile end

Required tolerance

For continuous production, servo-controlled punching can synchronize hole positions with the moving strip.

This is already common in solar structural roll forming. KINGREAL's PV support equipment, for example, combines feeding, punching, forming, and cutting in one automated process.

For a PV module frame, however, the punching solution must be designed around the frame geometry rather than copied directly from a mounting-channel machine.

After the cross-section is formed, the continuous profile must be divided into individual frame members.

The required cutting method depends on:

Material

Profile shape

Finished length

Production speed

End-face requirements

Downstream corner assembly

A frame manufacturer should determine whether the line requires:

Stop cutting

Flying cutting

Saw cutting

Hydraulic cutting

Specialized end cutting

The cut must not distort the profile, especially around thin lips or interlocking sections.

For module manufacturers using automated frame assembly, consistent finished lengths are particularly important because dimensional errors can accumulate when four frame members are joined into a rectangular module perimeter.

PV Manufacturer Type	Recommended Machine Focus	Key Requirement
Small/Medium Module Factory	Dedicated frame roll former	Simple operation and stable output
High-Volume Module Producer	Automated production line	Continuous operation and material handling
Steel Frame Manufacturer	Heavy-duty/custom roll former	Material strength and forming force
Aluminum Frame Producer	Aluminum-specific tooling	Alloy, temper and bend-radius control
OEM Frame Supplier	Customized profile line	Multiple frame drawings and quick changeover
Integrated PV Manufacturer	Multi-line engineering supplier	Frame + mounting profile production

This classification is more useful than selecting equipment according to machine price alone.

Among the six suppliers, IUWON's strongest positioning is its combination of solar profile experience, customized roll forming, and complete production-line engineering.

Its current solar equipment portfolio covers solar rails, C/U/Z/H profiles, strut channels, PV mounting brackets, support posts, purlins, and customized racking components.

Its dedicated solar panel frame and strut page also identifies solar panel frames as one of the profiles that can be produced and states that the equipment can support galvanized steel, aluminum, and coated materials.

The company reports:

20+ years of industry experience

50+ countries served

3M+ m² factory area

50M+ annual sales

and describes its business as integrating design, production, service, and global trade.

More importantly for a B2B PV manufacturer, IUWON emphasizes customized engineering based on customer drawings, production capacity, and application requirements.

This is relevant because PV module frames are rarely interchangeable products. The machine must be matched to the actual cross-section, material, dimensions, joining method, and production target.

Before asking a supplier for a quotation, a PV module manufacturer should prepare a technical package containing:

Complete frame cross-section drawing

Material type

Alloy or steel grade

Material thickness

Coil width

Required profile length

Hole and slot drawings

Corner connection method

Surface treatment

Required dimensional tolerance

Target production speed

Daily/monthly production volume

Required automation level

Factory power supply

Available installation area

The supplier should then provide a forming-line proposal that includes the forming sequence, roller design, machine configuration, punching system, cutting method, estimated output, and testing procedure.

The market for PV module manufacturing equipment includes both dedicated solar frame machinery and general industrial roll forming systems that can be customized for photovoltaic profiles. The six companies discussed above-IUWON, Nantong Reliantt Machinery, Wuxi Sunway Machinery, KINGREAL, Samco Machinery, and The Bradbury Group-represent different equipment strategies and should be viewed as options rather than a definitive ranking.

For manufacturers specifically producing module frames, the most important issue is whether the supplier can reproduce the exact frame profile with the required material, tolerance, length, and production rate.

A dedicated machine may be appropriate for a straightforward steel frame, while a highly customized production line may be necessary for an aluminum profile with multiple grooves, mounting interfaces, or special corner connections.

For international PV manufacturers, IUWON is particularly relevant when the project requires custom profile engineering rather than a standardized machine. Its solar portfolio covers a broad range of photovoltaic profiles, while its engineering model supports customized production lines based on drawings, materials, and production requirements.

The most effective next step is to provide the supplier with the frame drawing + material specification + finished length + required output + punching requirements. With those parameters, the machine can be engineered around the actual PV module rather than selected from a generic machine category.
