Qatar Marine Rock Wool Panel Automatic Hot Press Production Line Case: Supporting Automated and Continuous Manufacturing

The rapid development of LNG carriers, offshore engineering equipment, and commercial shipbuilding projects across the Middle East has significantly increased the demand for marine rock wool insulation panels and fire-rated sandwich panels. Shipbuilders require insulation products that not only meet fire protection and thermal insulation standards but also maintain consistent bonding quality, dimensional accuracy, and reliable delivery schedules.

Traditional production methods often rely on multiple standalone machines and manual material handling. This approach can lead to workflow interruptions, inconsistent panel positioning, higher labor requirements, and variations in hot pressing quality. As manufacturers begin serving international shipyards, production automation and process consistency become increasingly important.

The customer, located in Qatar, specializes in manufacturing marine rock wool insulation panels and fire-resistant sandwich panels for commercial vessels, offshore engineering projects, and marine interior systems.

To support growing international demand, the customer required a fully integrated production line capable of connecting every manufacturing stage—from material feeding to finished product palletizing—while supporting continuous production and improving factory management efficiency.

Foshan Henglihao Machinery Co., Ltd. designed and delivered one complete Marine Rock Wool Panel Automatic Hot Press Conveying Production Line within a 50-day delivery schedule.

The integrated production line includes:

• Automatic Feeding Machine
• Automatic Glue Spreading Machine
• Automatic Flipping Machine
• Three-layer Automatic Hot Press Machine
• Cylinder-type Automatic Turning Machine
• Gantry Automatic Palletizing Machine

The automatic conveying system connects each production stage, reducing manual handling and supporting a smoother manufacturing workflow. The automatic glue spreading system provides more uniform adhesive application before hot pressing, while the three-layer hot press structure enables flexible production scheduling. Automatic turning and gantry palletizing further streamline finished product handling.

According to the equipment specifications, the production line features a three-layer hot press structure, a 30-ton hydraulic pressing system, 2700 * 1100 mm hot press platens, and an electric thermal oil circulation heating system with temperatures up to 100°C, providing stable conditions for continuous lamination of marine rock wool panels. These technical specifications are taken directly from the product documentation.

After commissioning, the customer reported that the automated production process significantly improved workflow coordination between production stages, making daily operations more organized and supporting the continuous manufacturing requirements of international shipbuilding projects.

The customer commented:

"This production line has become a key competitive advantage for winning international shipyard projects. Visitors from Saudi Aramco and CMA CGM highly recognized our manufacturing capabilities during factory visits. We are now planning to expand our second production line and will prioritize further cooperation with Henglihao."

This feedback demonstrates that an integrated automated production line not only improves manufacturing organization but also strengthens a factory's capability when serving international customers.

Key technical features of this production line include:

• Three-layer hot press structure supporting flexible production scheduling.
• 30-ton hydraulic pressing system providing stable pressing conditions for marine rock wool panel lamination.
• 2700 * 1100 mm hot press platens suitable for large-format insulation panels.
• Electric thermal oil circulation heating system with temperatures up to 100°C to support stable curing conditions.
• Integrated automatic feeding, glue spreading, flipping, hot pressing, and palletizing process for continuous production.

For manufacturers producing marine insulation panels and fire-resistant rock wool sandwich panels, integrated automation is becoming an important factor in meeting international shipbuilding requirements.

The Marine Rock Wool Panel Automatic Hot Press Conveying Production Line from Foshan Henglihao Machinery Co., Ltd. combines automatic feeding, glue spreading, three-layer hot pressing, panel turning, and gantry palletizing into one continuous production solution. This integrated approach helps manufacturers establish stable production workflows, improve manufacturing organization, and prepare for future capacity expansion while supporting international marine projects.
