Haifeng successfully installed and commissioned an automated continuous cleanroom sandwich panel line for a major pharmaceutical engineering contractor in Russia, achieving ultra-flat wall and ceiling panels configured for the specified cleanroom panel application. The project featured specialized roll formers for flush joints, a 30m continuous double-belt laminator, and high-precision rock wool/polyurethane composite injection modules.

Prior to commissioning, the customer utilized manual batch presses that produced uneven, wavy panels with rough joint seams. These defects trapped airborne dust and failed pressure-decay audits in ISO Class 5 vaccine facilities. The client required an automated continuous lamination line capable of processing medical-grade anti-static steel sheets, holding tight surface tolerances of ≤0.3 mm over a 1 m measurement length, and embedding elastomeric sealant channels seamlessly.

Operational since April 2021 on a two-shift daily schedule across a 1,600 m² workshop, the installation provides stable output of 3,500 m² of high-grade cleanroom panels per shift. By deploying Haifeng's high-rigidity 30m double belt and dust-free tracking saws, the client manufactures wall and ceiling systems intended for the specified controlled-environment application for pharmaceutical facilities across the CIS region.

Area output per shift is a supplied project reference. Effective width, shift duration, running time, changeovers and accepted-panel yield must be specified before deriving or comparing area capacity.

Haifeng deployed an ultra-precision continuous sandwich panel lamination line optimized for pharmaceutical and electronic cleanroom specifications, controlling surface variation and achieving flush joint air-tightness:

1. High-Precision Sheet Roll Forming & Leveling: Cold roll forming stands feature micro-adjustable rolls to produce flush cleanroom tongue-and-groove profiles with integrated silicone gasket channels, ensuring a flat surface without edge curl.
2. Rock Wool Fiber Orientation & Dynamic Gluing: Raw rock wool slabs are automatically slit and turned 90 degrees vertically to maximize compression stiffness, followed by dual-component polyurethane adhesive spraying for total bonding.
3. Polyurethane Edge Foaming & Metering: High-pressure metering heads inject polyurethane foam into panel edges simultaneously, providing structural edge sealing and preventing moisture penetration.
4. 30m Precision Heated Double Belt: The heavy-duty continuous double belt applies calibrated, uniform pressure at 60°C across the 30-meter track, holding panel thickness variance within ±0.3mm.
5. Dust-Free Synchronous Cutting: A customized disc-saw unit tracks panel linear velocity in real-time, executing high-speed, dust-controlled transverse cuts with integrated HEPA vacuum extraction.
