Clean Room PU Sandwich Panel Machine

The cleanroom polyurethane sandwich panel machine is a core equipment system specifically designed for manufacturing wall panels and ceiling panels required for high cleanliness environments. This type of equipment integrates multiple functions such as material conveying, foaming molding, compression molding, and cutting and trimming, and can produce sandwich panels with excellent insulation and sound insulation performance and extremely high surface flatness.

Equipment selection suggestions:

• Select appropriate specifications based on annual production demand. For small-scale production, a semi-automatic sandwich panel production line can be selected, while for large-scale production, a fully automatic sandwich panel production line is recommended

• Considering the demand for product diversity, choose a multifunctional model that can quickly change molds

• Prioritize selecting manufacturers with a comprehensive after-sales service system

Key daily maintenance:

• Regularly inspect the mixing head of the foaming machine and recommend comprehensive maintenance every 500 hours

• Keep the press guide rails clean and lubricate them once a week

• Cutting tools need to be ground after producing 2000 square meters of boards

• The electrical system undergoes comprehensive testing every quarter

• Establish complete equipment operation records to achieve preventive maintenance

The technological advancement of pu sandwich panel machines in cleanrooms is driving the cleanroom construction industry towards higher efficiency, environmental friendliness, and intelligence, providing better purification environmental solutions for fields such as semiconductors, pharmaceuticals, and biotechnology.
