Preparation work

• Check equipment:
  Before using the PU Sandwich Panel Machine, a comprehensive inspection of the equipment should be conducted, including whether the power, air pressure, hydraulic and other systems are normal.
  Confirm that all fasteners are secure and that the transmission components are well lubricated.

• Preparation materials:
  Prepare an appropriate amount of polyurethane raw materials, sandwich panel materials, and other auxiliary materials according to production needs.
  Ensure that material quality meets production requirements and avoid using expired or substandard materials.

Startup and Debugging

• Start device:
  According to the instructions in the equipment operation manual, start the power, pneumatic, hydraulic and other systems in sequence.
  Observe the operation status of the equipment to ensure that there are no abnormal sounds or vibrations.

• Debugging parameters:
  Adjust various parameters of the equipment, such as temperature, pressure, speed, etc., according to production requirements.
  Conduct no-load trial operation to check whether the equipment actions are coordinated and accurate.

Mold assembly and pouring

• Mold assembly:
  Assemble the sandwich panel mold on the workbench, ensuring that the mold is flat and undamaged.
  Select the appropriate mold size and shape based on production requirements.

• Polyurethane infusion:
  After mixing the polyurethane raw materials evenly in a certain proportion, they are injected into the mold through a pouring device.
  Control the infusion speed and pressure to ensure even distribution and filling of the mold with polyurethane.

Foaming and shaping

• Foaming:
  The polyurethane raw material in the mold begins to foam, forming the core layer of the sandwich panel.
  Observe the foaming process to ensure even and normal foaming.

• Stereotyping:
  After foaming is completed, the mold is pressurized and heated using equipment to shape the polyurethane sandwich panel.
  Control the shaping time and temperature to ensure that the sandwich panel achieves the required hardness and strength.

Demoulding and subsequent processing

• Demoulding:
  After the shaping is completed, open the mold and remove the polyurethane sandwich panel.
  Check the surface quality of the sandwich panel and promptly address any defects.

• Subsequent processing:
  Cut and trim the extracted sandwich panels for subsequent processing to meet production requirements.
  Pack, store or transport the processed sandwich panels.

Precautions

• Safe operation:
  When operating the PU Sandwich Panel Machine, it is necessary to strictly follow the safety operating procedures and wear personal protective equipment.
  Avoid conducting maintenance or adjusting parameters while the equipment is running.

• Maintenance and upkeep:
  Regularly clean, lubricate, and inspect equipment to ensure that it is in good working condition.
  If any equipment malfunction or abnormality is found, the machine should be stopped in a timely manner and professional personnel should be contacted for maintenance.

• Quality control:
  Strictly control the quality of raw materials and production process parameters to ensure that the produced polyurethane sandwich panels meet quality standards.
  Strictly control every step of the production process to ensure stable and reliable product quality.

By following the above steps, the PU Sandwich Panel Machine can be effectively used for production. However, please note that there may be differences in PU Sandwich Panel Machines of different brands and models, so in actual operation, specific equipment operation manuals and instructions should be referred to.
