Three-quarter view of the drive side of the rock wool sandwich panel line: a bright red horizontal drive shaft runs along the frame through pillow-block bearings, driven by blue gearbox motors and a heavy-duty chain-and-sprocket system. Black spoked handwheels let operators adjust roller gaps for different core thicknesses, while the light green conveyor bed carries the rock wool core material toward the Z-Lock edge-forming stations.
Low-angle close-up of the laminating section of the rock wool sandwich panel line: the green pebbled conveyor belt moves the panel over white plastic roller beds, guided by an orange side rail, while two silver pneumatic cylinders on a black crossbar control the covered top roller pressure. The white-faced board seen here is bonded with its core so the Z-lock edges stay true through curing and cutting.
Close-up of the forming stage of the rock wool sandwich panel line: chrome-plated segmented rollers with profile grooves press the steel skin, with large coiled springs and heavy adjustment bolts on the blue bearing housings controlling gap and pressure. Orange guide rollers keep the sheet aligned before it enters the edge-locking stations that shape the Z-profile for fire-rated panels.
Low-angle interior view of the transport section of the rock wool sandwich panel line: heavy black-rubberized rollers grip the panel surface without damage, supported by long rows of small orange polymer guide rollers, while circular mounting flanges and large threaded bolts anchor the high-torque bearing assemblies. The deep-blue columns frame the line as the bonded board travels toward stacking, its Z-lock edges ready for installation.
Rock Wool Sandwich Panel Line - Built by XINNUO Since 1995
XINNUO has engineered cold roll forming equipment for the building industry since 1995, with more than 30 years of continuous manufacturing practice. Our factory is one of China's experienced producers of rock wool sandwich panel line equipment, including Z-Lock (S-type interlock) configurations dedicated to A-grade fire-rated panels.
The rock wool sandwich panel line feeds mineral wool slabs continuously into the lamination zone between the two profiled steel skins, bonds the three layers under controlled pressure, forms the interlocking Z-edges at dedicated edge-locking stations and cuts panels to length in one continuous flow. The full S-type configuration runs approximately 65 meters and delivers fastener-free panels with tight seam tolerances - the specification demanded by cold storage, cleanroom, food processing and plant building projects in fire-code-strict markets.
We also supply standard lap-joint composite panel lines, EPS/PU core lines, single and double-layer forming machines, purlin lines, floor deck lines and custom special profiles. Every line is designed, welded, assembled and test-run in our own workshop, and we have served more than 150 countries with installation guidance, operator training and dependable after-sales support.
FAQ
Q1: What is a rock wool sandwich panel line?
A: A rock wool sandwich panel line profiles two steel skins, feeds mineral wool slabs between them, bonds the layers under controlled pressure and cuts panels to length - producing A-grade fire-rated insulated panels in one continuous process.
Q2: Why choose rock wool as the core material?
A: Rock wool is non-combustible (A-grade), provides excellent sound insulation and withstands high temperatures, making it the required core in fire-code-strict markets such as the Middle East, Europe and Australia.
Q3: How is the rock wool fed into the line?
A: Mineral wool slabs are fed continuously on the conveyor bed into the lamination zone, where the profiled steel skins and the core are brought together under the pressure rollers - no glue injection is needed for rock wool cores.
Q4: Can this line form Z-Lock edges?
A: Yes. Dedicated edge-locking stations with precision rollers shape the S-type interlocking Z-profile on both edges during the same continuous pass, producing fastener-free panels with tight, consistent seam tolerances.
Q5: What panel widths and core thicknesses can it produce?
A: Common effective widths are 950mm, 970mm, 1000mm, 1050mm and 1120mm. Roller gaps are adjustable with handwheels and adjustment bolts, so different core thicknesses can be run on the same line.
Q6: Where are rock wool Z-Lock panels used?
A: Cold storage rooms, cleanrooms, food processing plants, pharmaceutical facilities, plant buildings and any project requiring fire-rated, airtight insulated panels without exposed fasteners.
Q7: What fire rating do the finished panels achieve?
A: With a rock wool core and A-grade adhesive systems, the panels meet A-class (non-combustible) fire performance requirements common in international building codes.
Q8: How do I get a quotation?
A: Send your panel drawing or sample, core material, width and daily output target via WhatsApp/Wechat +86 188 0307 8605 or email sara@xinnuomachine.com. We reply within 24 hours.
