Core Module

• Raw material processing system
  Uncoiler and steel plate feeding device: high-precision servo control is adopted to ensure the smooth transportation of metal coils (color steel, aluminum foil) or soft substrates (non-woven fabric, cement cloth).
  Automatic docking technology: Seamless connection of rolls is achieved through laser positioning, reducing downtime.

• Forming and foaming system
  High pressure foaming unit: Multi component (2-9 group distribution ratio optional) polyurethane high-pressure foaming technology, with a mixing head atomization accuracy of ± 1%, supporting environmentally friendly foaming agents such as pentane.
  Double track laminating machine: designed with a length of 24-36 meters, equipped with hydraulic lifting and hot air circulation system (temperature control ± 2 ℃) to ensure uniform foaming and curing of the core material.

• Intelligent cutting and post-processing
  Follow up cutting saw: Integrated visual recognition system, can automatically track board joints or preset marks, with a cutting accuracy of ± 0.5mm.
  Automatic palletizing robot: Load capacity ≥ 500kg, supports layered stacking of soft/hard decorative panels.

Sinowa's modular assembly concept enables quick replacement of key components such as molding stations and mixing heads, reducing production line switching time to 30 minutes. It is compatible with various core materials such as polyurethane (PU), rock wool, and glass wool.

Typical Ccenario
