Product details

Traditional phenolic foaming relies on thermal conduction heating, requiring the entire mold to reach 180°C+ over 20–30 minutes, with energy costs of ¥300–400 per cubic meter and a pass rate of only 85%–90%. Shijiazhuang Hongtao Technology Co., Ltd. breaks through with microwave energy technology, introducing the Phenolic Foam Microwave Rapid Expansion & Drying Equipment (QW-35, 35kW). It compresses the foaming cycle from 30 minutes to just 5–8 minutes, boosting single-line daily output from under 100 m³ to 200–300 m³.

The equipment features a multi-mode resonant cavity design with infrared temperature sensing and PLC closed-loop control, delivering "gradient-free" uniform heating. This eliminates the persistent problem of traditional processes—incomplete internal foaming with surface overburning. Tested data shows electricity consumption of just 150–200 kWh per cubic meter, reducing costs from ¥300 to approximately ¥160, saving over ¥1.4 million in annual electricity costs. Products achieve A2-grade fire rating with a pass rate soaring to 98%+, giving companies a competitive edge in engineering bids.

The factory-direct model eliminates 30%–50% middleman markups. The QW-35 is priced at just ¥286,000, 20%–30% lower than dealer channels. The company offers a 3-year full warranty, lifetime free technical upgrades, turnkey installation and commissioning, with stable production achievable within 24 hours. The modular production line occupies only 60% of the floor space of traditional lines—just 80 m² is enough to start production, ideal for factory retrofits.

The Hebei Provincial Quality Inspection Institute reports that the A2-grade fire rating pass rate for microwave-processed phenolic products is 15 percentage points higher than traditional methods. Whoever masters the "fast, uniform, economical" microwave foaming technology first wins the next decade.
