A panel manufacturer who has watched peel strength fall on a batch of A2 panels after a wet shipping season usually wants one thing from the next line: a core that does not take on moisture. That is the idea behind the Extrusion Type Zero Water Absorb A2 Noncombustible Metal (Aluminum) Composite Panel Production Line from Zhangjiagang Hongyang Machinery Equipment Co., Ltd. Instead of pressing mineral-filled sheets in a hot press, the line extrudes the A2 core continuously through a screw, then laminates it between aluminum skins.
The short answer for buyers is this. The line deserves a close look if your priorities are moisture stability, continuous output and in-house control of the core. The manufacturer reports near-zero water absorption for its extruded core, compared with 3 to 7 percent for conventional A2 cores. It also reports extrusion speeds above 3 m/min, panels classified A2-s1,d0 under both GB 8624-2012 and EN 13501-1, and a peel strength of at least 120 N/mm.
The line is described as a full-chain system with three possible outputs: finished A2 non-combustible aluminum composite panels, A2 core granules for factories that already run extrusion equipment, and A2 core rolls for panel makers who want to laminate without extruding in-house. The manufacturer states a panel output of 5,000 square meters per day. That flexibility matters because a buyer can enter at the stage that fits current capability and expand later.
This guide is written for factory owners, plant engineers and purchasing managers comparing an extrusion type A2 production line manufacturer, supplier or exporter. Here is what the sections below cover:
Choose this type of line when moisture stability and continuous production matter more than staying with a familiar hot-press process.
A2 panels get their fire performance from a core with very high mineral content. That mineral content is also what makes many conventional A2 cores porous. According to the manufacturer, these cores absorb roughly 3 to 7 percent moisture, and the absorption continues as long as humidity stays high. Once the core holds water, the adhesive bond between core and aluminum skin can weaken, and the manufacturer cites a peel strength loss of more than 20 percent after moisture exposure.
The effect is rarely visible on the factory floor. It appears later, in places a buyer cannot easily control. A pallet crosses an ocean in a container that sweats in the heat. A project warehouse near a port stores panels for several weeks before installation. A facade in a humid climate faces months of damp air before the sealant work is finished. In each case a core that takes on water can add weight, soften the bond line and raise the risk of edge delamination.
Transport adds a quieter issue. Moisture weight gain changes shipping weights, and damaged panels from wet storage can lead to rejected deliveries. The manufacturer lists lower logistics loss as a practical benefit of a core that does not gain moisture.
The chart below compares the figures the manufacturer gives for conventional A2 cores and its extruded core. Read it as a statement of design intent that buyers should confirm with their own humidity conditioning tests.
The grey columns show conventional A2 cores at the low and high ends of the stated 3 to 7 percent absorption range, followed by the reported peel strength loss of more than 20 percent after moisture exposure. The red columns show the extruded core at near-zero absorption with no reported peel loss. For a manufacturer in a humid region, this difference can change how much margin is needed in storage and shipping plans. The extrusion type line is built around this property, so buyers evaluating it should ask for moisture conditioning data that matches their own climate and project type.
Moisture behavior of the core is a quality factor that appears after delivery, so test it before you commit to a core technology.
Screw extrusion is a familiar process for plastics, but it has a practical limit: when the filler share climbs very high, the melt becomes hard to process. Mineral-filled A2 materials are exactly in that range. The manufacturer says its proprietary technology couples inorganic flame retardants with organic polymers at the molecular level, which is what lets the line extrude cores with at least 90 percent inorganic content.
A2 classification places strict limits on how much combustible material a panel may contain and how it behaves in a fire. A core with a very high inorganic share has little organic material available to burn. The challenge is to keep that core flexible enough to be processed and laminated. Coupling the two phases is the manufacturer's way to solve this.
| Item | Stated value |
|---|---|
| Composition | Inorganic content of at least 90 percent |
| Flame retardancy | A2 rated |
| Processing | Twin-screw or single-screw extrusion |
| Daily output | 200 tons across 8 production lines |
The chart below shows the stated composition of the granules as a progress ring. It makes the proportion easy to see and gives buyers a simple reference during technical discussions.
The red arc represents the inorganic share of at least 90 percent, and the small grey section shows the organic binder and additives. Because the inorganic share is so high, process control on the extruder matters more than on conventional plastic lines. Feed rate, screw speed and temperature profile all influence melt quality, and the supplier's experience with these settings is part of what a buyer is purchasing. Ask for a trial run on the granule type you plan to use, and ask how the control system records screw torque and melt temperature.
A high mineral share only delivers value if the extrusion process stays stable, so evaluate the supplier's process control, not just the recipe.
Most A2 composite panels on the market are made by forming mineral-filled cores in a hot press and then bonding the core to skins. That method is mature, but it is a stop-and-go process. The extrusion route is continuous: granules enter the extruder, the core leaves as a roll or sheet, and the lamination section bonds it to the aluminum skins with an adhesive film.
The manufacturer gives the extrusion speed as above 3 m/min, against below 2 m/min for conventional hot-press forming. Continuous running also supports batch consistency, because the process does not restart with each pressing cycle. Temperature and thickness settle into a steady state, and operators spend more time monitoring than loading.
To make the speed difference concrete, the area chart below converts the two stated speeds into the length of core produced over an 8-hour shift. The calculation uses the speed limits quoted by the manufacturer, so it shows the minimum extruded output against the maximum hot-press output.
At 3 m/min, a line running for 8 hours produces about 1,440 meters of core, while a hot-press process at 2 m/min produces about 960 meters over the same time. That is a difference of roughly 480 meters per shift, or about one half more output at the stated limits. In practice both processes have downtime, changeovers and width adjustments, so real numbers will differ. Still, a buyer planning to supply large facade projects can use this arithmetic to compare how much additional capacity an extrusion type A2 production line could add to a plant.
| Dimension | Conventional A2 ACP | Extruded A2 |
|---|---|---|
| Core process | Mineral-filled core with hot-press forming | Supramolecular coupling with screw extrusion |
| Water absorption | 3 to 7 percent, continuing in humidity | Near zero |
| Peel strength after moisture | Loss of more than 20 percent | No loss reported |
| Core flexibility | Brittle, may crack when bent | Good elongation, bendable |
| Bonding method | Hot press with adhesive film | Continuous hot lamination with adhesive film |
| Production speed | Below 2 m/min | Above 3 m/min |
| Batch consistency | Noticeable variation | High consistency in continuous running |
| Recyclability | Difficult | Designed for reuse of offcuts |
| Transport loss | Weight gain and damage from moisture | Lower loss, no moisture gain |
Core flexibility deserves a note of its own. A brittle core can crack when panels are routed and folded for facade cassettes. A core with better elongation is easier to fabricate, which reduces rework at the fabricator's workshop. That downstream benefit is easy to overlook when comparing equipment only on throughput.
Continuous extrusion changes both speed and consistency, so compare lines on output per shift and batch variation together.
Hongyang describes the line as a full-chain system from granules to finished panels. The practical meaning is that three different products can come out of the same technology, and a buyer can decide which one fits the business.
The finished panel uses an extruded A2 inorganic core between metal skins. The manufacturer states a capacity of 5,000 square meters per day and lists certification references under EN 13501-1, GB 8624-2012, BS 476 and ASTM E84. This is the route for a manufacturer that wants to run the entire process under one roof.
Granules are the raw form of the core. They are made for manufacturers who already have extrusion lines and want to produce A2 cores on equipment they own. The manufacturer states a granule output of 200 tons per day across 8 production lines.
Core rolls are continuously extruded core on a roll, ready for hot lamination with metal skins. They are meant for composite panel manufacturers who want to skip in-house extrusion. The stated output is 50 tons per day from one production line, and the rolls can also be used in other sandwich structures that need a non-combustible core.
| Output | Form | Stated capacity | Suited to |
|---|---|---|---|
| A2 composite panel | Finished panel, 2 to 6 mm thick | 5,000 square meters per day | Manufacturers seeking a complete line |
| Core granules | Extrusion-ready granules | 200 tons per day, 8 lines | Factories with existing extrusion lines |
| Core rolls | Continuous core on roll | 50 tons per day, 1 line | Panel makers who laminate only |
The company says that buyers can purchase any intermediate product as needed. This is useful for manufacturers who want to start with core rolls to test the market, then add granule and extrusion capacity when volumes justify it.
Start from the stage where your factory is strongest and add upstream capacity as demand grows.

As a factory-direct extrusion type A2 production line manufacturer and exporter, the company supports wholesale procurement, OEM project customization and long-term service. Owning the process from core granules to finished panels allows one counterpart to handle design, supply and training.
A manufacturer that controls granules, core rolls and finished panels in-house can support buyers at every stage of a line project.
Technical data tells buyers what the panel is meant to achieve and what their quality team will need to check. The manufacturer publishes the following values for its extrusion type A2 panel, reported as third-party test data under the stated standards.
| Property | Standard | Value |
|---|---|---|
| Total thickness | GB/T 17748-2008 | 2, 3, 4, 5 or 6 mm |
| Aluminum skin thickness | GB/T 17748-2008 | 0.2, 0.3, 0.4 or 0.5 mm |
| Width | Not specified | Up to 2000 mm, customizable |
| Fire classification | GB 8624-2012 | A2-s1,d0 |
| Fire classification | EN 13501-1 | A2-s1,d0 |
| Fire classification | BS 476 parts 6 and 7 | Class 0 and Class 1 |
| Surface burning | ASTM E84 | Class 1, flame spread 25 or below, smoke developed 50 or below |
| Facade full-scale fire | NFPA 285 | Recorded as a pass |
| Peel strength | GB/T 17748 | At least 120 N/mm |
| Flexural strength | GB/T 17748 | At least 150 MPa |
| Face coating | Not specified | PVDF, PE or custom |
In A2-s1,d0, the A2 part indicates limited contribution to fire, the s1 part indicates low smoke production, and d0 indicates no flaming droplets in the test. BS 476 Class 0 and Class 1 are references used in several markets that inherited British standards, and ASTM E84 is a surface burning test widely used in North America. NFPA 285 is a full-scale facade test that checks how a wall assembly behaves, not only the panel itself.
Fire test results apply to the configuration that was tested. A change in skin thickness, coating or adhesive film can matter for some tests, so buyers should line up the report list with their intended product range early in the project.
Match every report to the exact panel build-up you plan to sell before relying on a classification in a tender.
The manufacturer lists five scenarios for the panels made on this line. Each one connects to a different buyer concern, and each affects how a manufacturer plans its sales effort.
High-rise projects often require strict fire-rated materials, and specifiers look for classifications such as A2-s1,d0. A panel manufacturer serving this segment benefits from complete documentation and consistent batches, because a single project may need many thousands of square meters delivered over months.
These building types carry high occupancy and strict evacuation rules, so non-combustible cladding is frequently specified. In humid regions or coastal sites, a core that does not absorb moisture helps support the long-term appearance and bond of the panel.
Many renovation projects follow updated fire safety requirements and replace older cladding. Panels with good bendability are easier to fabricate into custom shapes for retrofit conditions, which can help installers when dimensions are not uniform.
Manufacturers selling in several regions need panels that can meet different classification systems. The manufacturer lists test references from China, the European Union, the United Kingdom and the United States, which supports conversations with buyers in those markets. Each market should still be checked for local approval rules.
Large projects need steady supply. Continuous extrusion and a vertically integrated chain help a factory plan lead times, because key materials come from the same source and the process does not depend on batch pressing cycles.
Match the panel's strengths to the scenario: moisture stability for humid sites, consistency for large projects and documented classification for export.
Material handling is part of any production line decision, and it affects how a factory manages waste and shipping. The manufacturer states that production offcuts can be processed and reused in core extrusion. This closes a loop that conventional hot-press cores are said to make difficult, since mineral-heavy pressed cores are hard to reprocess.
The manufacturer also notes that installation scrap at the customer's site has recycling value. For a fabricator that cuts panels into cassettes, offcuts are a real part of the material stream, and a take-back or reuse arrangement can reduce disposal volumes. The practical extent of this depends on collection systems and local rules, so buyers should discuss arrangements with the supplier directly.
On the logistics side, a core that does not gain moisture avoids the weight changes and damage that wet storage can cause. That makes shipping documentation simpler and can reduce disputes on delivery. These are benefits that rarely appear on a datasheet but show up in daily operations.
Ask for a clear offcut reuse procedure, because recycling benefits depend on process details and not only on material properties.
Technology decisions are easier when the trade-offs are visible. The matrix below groups six factors that buyers commonly weigh when they compare conventional hot-press A2 production with an extrusion type line. It uses the manufacturer's own comparison as its source and adds one factor where the conventional approach has an advantage.
Extrusion type A2 production scores higher on moisture stability, speed, consistency, flexibility and recyclability, according to the manufacturer's comparison. Conventional hot-press production keeps an advantage in market track record, since it has been used for longer and many fabricators are familiar with it. A buyer should weigh those factors against local conditions. In a humid market with large facade orders, the first five rows may carry more weight than familiarity. In a market where fabricators resist new materials, the sales effort for a newer core may need extra support, including training material and sample panels.
It is reasonable to ask the supplier for reference customers, sample panels and a visit to a running line. Seeing the process in operation gives more information than any table, and it lets your engineers check details such as edge quality and surface flatness.
Treat the matrix as a starting point and replace the ratings with your own after a factory visit and sample testing.
A production line only creates value when it reaches stable output. Hongyang offers project services, remote service and on-site service, and quotes a 48-hour global emergency response. The company also reports commissioning cycles about 30 percent shorter than industry standards and holds 70 core patents, ISO 9001 certification and CE certification. These are useful reference points, and buyers should confirm how they apply to their own project.
| Risk | What it looks like | How to reduce it |
|---|---|---|
| Mismatched test reports | Classification does not cover the product sold | Match each report to the exact panel build-up |
| Extruder instability | Variable core thickness or density | Review process control and run trial batches |
| Moisture exposure in transit | Weight gain or bond problems on arrival | Ask for conditioning data and packaging advice |
| Slow ramp-up | Output grows slowly after installation | Agree milestones and training plans in the contract |
| Unclear raw material route | Delays in granule or roll supply | Decide early between buying intermediates or producing them |
Many of these risks are cheaper to address at the planning stage, when the configuration is still flexible. Documenting expectations early also makes it easier to compare suppliers on equal terms.
Agree specifications, test evidence and commissioning milestones in writing before equipment ships.

Choosing an extrusion type A2 production line is a decision about material technology as much as machinery. A supplier that explains its core process, shares test references and offers structured commissioning support gives buyers the information they need to compare options with confidence.
Begin with your target market and panel specification, then bring a written requirement list to the first technical meeting.
A1. It is a manufacturing system that extrudes an A2 non-combustible core through a screw and laminates it between aluminum skins. The manufacturer describes it as a full-chain line that can produce core granules, core rolls and finished panels.
A2. It refers to a core that takes on very little moisture. The manufacturer states near-zero absorption for its extruded core, compared with 3 to 7 percent for conventional A2 cores, and reports no peel strength loss after moisture exposure. Buyers should confirm this with their own conditioning tests.
A3. The published data lists A2-s1,d0 under GB 8624-2012 and EN 13501-1, Class 0 and Class 1 under BS 476 parts 6 and 7, Class 1 under ASTM E84, and a recorded pass under NFPA 285. Check that each report matches the panel build-up you plan to sell.
A4. The manufacturer states an extrusion speed above 3 m/min, compared with below 2 m/min for conventional hot-press forming. Over an 8-hour shift this is about 1,440 meters against 960 meters at the stated limits, before downtime and changeovers.
