High-Flow PU Foam Machine for Box Foam Blocks | Haifeng

This high‑flow polyurethane foaming machine is specially designed for manufacturing polyurethane solid tires, matching supporting demands of AGV trolleys, electric forklifts, automobile spare tires, airport baggage trailers, and flatbed transport vehicles—covering light‑load to medium‑heavy load tires of various specifications with wide applicability. The machine features a 200L tank system, discharge flow customizable from 1‑30 kg/min, a fixed A:B ratio of 1:1, and a mixing head speed of 4,000‑6,000 r/min. High‑temperature resistant, low‑speed, high‑precision metering pumps achieve ≤0.3% accuracy, ensuring stable mixing ratios and eliminating defects such as material shortage and uneven hardness. The optional vacuum degassing modules for raw material tanks and negative‑pressure auxiliary defoaming for mixing heads drastically reduce air content inside mixed materials—molded tire cross‑sections show no visible pores, effectively boosting yield. The machine features a full closed‑loop temperature management system from raw material storage to pouring outlet: each tank has independent circulating temperature adjustment; heat‑preserving water jackets wrap delivery pipelines; dedicated temperature control channels inside mixing heads dissipate frictional heat and actively heat in cold environments. Temperature deviation is limited within ±1°C, ensuring consistent quality across every batch. The PLC controller supports optional remote network access for fast fault diagnosis, automatically monitoring and triggering alarms when abnormalities occur.
