When procuring a foam mattress machine, you must prioritize foaming density control accuracy and cutting precision. Look for machines equipped with PLC control systems (such as Siemens or Mitsubishi) to ensure stable chemical ratios. Key specs include a foaming width of 1.5m to 2.4m, a production speed of 2-7 meters per minute, and high-precision horizontal/vertical cutting blades with a tolerance of less than ±1mm. Ensure the machine supports multi-density foaming to produce memory foam, high-resilience foam, and standard PU foam on a single line.
