Looking for top Rockwool sandwich panel machine manufacturers? The best ones do way more than just sell you a laminating line.
They design the whole production flow from start to finish. That includes sheet feeding, profiling, mineral wool prep, adhesive spraying, pressing, cutting, and automated stacking. They also handle the control systems, safety setups, and final commissioning so your plant runs smoothly from day one.
This 2026 shortlist helps panel producers compare ten verified equipment companies. Every manufacturer below publishes an official mineral-wool, rock-wool, or combined sandwich-panel line. The list is an editorial procurement guide, not an audited market-share ranking.
How We Ranked Rockwool Sandwich Panel Machine Manufacturers
We reviewed current manufacturer websites and official equipment documents available in August 2026. Selection favored companies that clearly document rock-wool or mineral-wool panel machinery, explain the complete line or a specialist section, support more than one panel format, and publish evidence of engineering, installation, customization, or after-sales capability.
Buyers should still complete their own technical and commercial due diligence. A place on this list does not certify a supplier, guarantee regional support, or prove that one standard line will produce every roof and wall panel specification.
Top 10 Rockwool Sandwich Panel Machine Manufacturers in 2026
1. YZ Welding – China
YZ Welding offers a multi-use polyurethane and rockwool panel production line for buyers who want to discuss more than one insulated-panel core. Its value is the ability to develop the configuration around the buyer’s panel width, thickness, length, facing material, factory space, and handling requirements. Ask YZ to separate the included rock-wool modules from optional PU/PIR equipment in the quotation.
2. Zhejiang Jinggong Science & Technology – China
Jinggong publishes one of the clearest complete-line descriptions in this group. Its rockwool continuous line can include coiling, filming, cutting and slitting, roll forming, preheating, rock-wool handling, adhesive spraying, side-seal foaming, double-belt pressing, band-saw cutting, stacking, and packing. It is a strong comparison point for buyers planning a highly integrated continuous plant.
3. KINDUS – South Korea
KINDUS documents a continuous mineral-, rock-, and glass-wool sandwich panel line for wall, roof, and other metal-faced products. Its published system scope covers decoiling, roll forming, mineral-wool board feeding, adhesive application, side PU injection, lamination, cutting, stacking, and wrapping. Buyers comparing automation and downstream packaging should place KINDUS on the technical shortlist.
4. IL KWANG Metal Forming – South Korea
IL KWANG lists dedicated polyurethane, mineral-wool, and EPS sandwich panel production equipment. The company describes its mineral- or glass-wool line as continuous automated equipment for producing different panel shapes. Its official catalog and published equipment documentation make it easier for procurement teams to review machine scope before requesting a detailed proposal.
5. SAIP Equipment – Italy
SAIP designs continuous and discontinuous sandwich-panel plants for polyurethane or mineral-wool cores. Its official material distinguishes mineral-wool panel lines and MIWO lines while also explaining continuous and lower-volume discontinuous production. SAIP is particularly relevant when buyers need process engineering and want to compare alternative production methods before fixing the final layout.
6. Olivotto Glass Technologies (OGT) – Italy
OGT supplies continuous or discontinuous rock-wool sandwich-panel plants and specialist Side Leg Mineral Wool systems. The company states that its mineral-wool sections can be integrated into an existing panel line or supplied within a new project. This makes OGT worth evaluating for both greenfield plants and targeted upgrades to wall or roof panel production.
7. ROBOR – Italy
ROBOR offers a mineral-wool section for continuous sandwich-panel lines. Its published process includes automatic board loading, strip cutting with circular discs, strip orientation, adhesive distribution, and dedicated trapezoidal-strip handling for roof panels. Buyers who already understand their main line but need detailed core-preparation engineering should review ROBOR’s modular approach.
8. GXTECH – China
GXTECH identifies itself as a manufacturer of PU/PIR and rockwool sandwich-panel lines as well as rock-wool insulation production lines. Its official website publishes manufacturing information and international project examples. The company is relevant for buyers who want to discuss both the panel-lamination process and upstream rock-wool production within a broader equipment project.
9. Shanghai Zhongji Machinery – China
Zhongji publishes mineral-wool and combined mineral-wool/EPS sandwich-panel equipment, including its SP-7 production-line family. Its portfolio also covers PU and other panel-machinery categories. Buyers considering several insulation products can use Zhongji as a comparison for multi-product factory planning, installation, training, and maintenance support.
10. Sinowa – China
Sinowa publishes a dedicated continuous rockwool sandwich-panel line. The stated process scope includes uncoiling, lamination and cutting, core-material processing, composite forming, curing, quality control, and automation. It is a practical supplier to compare when a buyer wants a continuous line specification and customized integration from one equipment source.

How to Choose a Rockwool Sandwich Panel Machine Manufacturer
Confirm the Panel Specification and Product Mix
Send every bidder the same panel schedule: wall or roof profile, finished width and thickness, facing material, mineral-wool density and lamella orientation, joint design, cut lengths, shift output, and required packaging. State whether the factory will produce only rock wool or also PU, PIR, EPS, or glass-wool panels.
Compare the Complete Line Scope
Normalize each quotation line by line. Check decoilers, roll formers, core cutting and turning, glue or side sealing, laminating and pressing, curing, cutting, cooling, stacking, wrapping, dust control, safety guarding, controls, and factory utilities. Our guides to combined PU/PIR/rockwool lines, continuous versus discontinuous production, and sandwich-panel factory layout can help define that scope.
Verify the FAT, Installation, and Support
Agree on a factory acceptance test using your facing sheets, mineral-wool boards, adhesive system, profiles, and panel sizes. Define measurable acceptance criteria for dimensions, bonding, surface quality, cutting, changeover, alarms, and continuous running. Also confirm installation supervision, operator training, documentation, PLC backup, remote support, warranty, and critical spare parts.
For a project-specific comparison, send YZ Welding your panel drawings, target output, core materials, and factory layout. We can prepare a rockwool sandwich panel machine configuration and a quotation checklist for your procurement team.
FAQ
Who makes complete rockwool sandwich panel production lines?
Manufacturers on this 2026 shortlist with documented complete-line capability include YZ Welding, Jinggong, KINDUS, IL KWANG, SAIP, GXTECH, Zhongji, and Sinowa. OGT and ROBOR also provide complete-project or specialist mineral-wool sections.
Can one line produce PU, PIR, and rockwool sandwich panels?
A combined line can be engineered for multiple cores, but rock-wool handling and bonding differ from foam processing. Confirm which modules are shared, which are separate, the changeover procedure, and the realistic output for each product.
What should I send manufacturers before requesting a quote?
Send panel drawings, core specifications, facing materials, production targets, product mix, available building dimensions, utilities, automation expectations, applicable standards, and your required factory acceptance test.
How should I compare rockwool sandwich panel machine prices?
Compare the delivered project scope rather than the headline price. Include freight, installation, utilities, tooling, adhesive and core systems, safety equipment, testing, training, spare parts, warranty, and the cost of reaching stable commercial production.
