Serving a passive house insulation board enterprise in Jiangsu - High-pressure polyurethane foaming production line solves the challenges of \"foam cell uniformity and thickness accuracy\".

Customer Background: A building materials enterprise in Jiangsu, specializing in polyurethane insulation boards for passive houses. Traditional production lines used low-pressure foaming technology, resulting in coarse foam cell diameter (0.5-1mm), board thickness deviation of ±3mm, and thermal conductivity exceeding standards (0.026W/(m·K), national standard 0.024), failing to meet the high energy-saving requirements of passive houses.

Challenges Faced:

Uneven foam cells led to unstable insulation performance, with a customer complaint rate of 15%;

Large thickness deviation required secondary cutting correction, resulting in an 8% scrap rate;

High energy consumption (1200 kWh per ton of product), keeping production costs high.

Aipake Solution:

Provided PF-H series high-pressure polyurethane foaming production line (dual-component high-pressure impingement mixing system) + laser online thickness measurement + closed-loop feedback system:

High-pressure mixing (200bar pressure) enables more uniform atomization of raw materials, foam cell diameter ≤0.2mm, thermal conductivity reduced to 0.022W/(m·K), meeting passive house standards;

Laser thickness gauge monitors board thickness in real-time, automatically adjusting the die head linkage, controlling thickness deviation within ±0.8mm, reducing scrap rate to 1%;

Waste heat recovery system + intelligent temperature control reduces electricity consumption per ton of product to 850 kWh, lowering energy consumption by 29%.

Results Achieved:

Became a certified supplier for the German Passive House Institute (PHI), won the bid for the Xiong'an New Area passive house project;

Annual reduction in scrap loss of 600,000 RMB, energy cost savings of 3.6 million RMB, new overseas orders accounting for 40%.
