Sandwich panels are construction material, metal sandwich panels production needs sandwich panel machines. Sandwich panel machines are divided into pu and rock wool according to the different materials in the middle of the metal plate. Polyurethane (PU) sandwich panel machinery also called PU sandwich panel production lines. PU sandwich panel production lines can be divided into continuous and discontinuous production. Weihua is a technology researcher and solution manufacturer for continuous production lines. With 15 years of hard work, Wuxi Weihua Machinery is a continuous sandwich panel production line manufacturer. It has completed the entire PU sandwich panel production line by itself and has obtained a number of patents, especially foaming machines and flat PU pannels.
Hydraulic uncoiler, Filming machine, steel panel lifting device, Cutting machine / cutting edge recycling device, Ribbing Roller, forming machine, steel panel pre-heat machine, high pressure foaming machine, PU pouring machine, side seal device, double-belt conveyor machine , heating device of double-belt conveyor, automatic tracking band-saw, output roller path, panel cooling system, automatic stacker, wrapping machine and so on.
Hydraulic uncoiler: steel coil feeding, recycled metal sheet
Filming machine: protect the surface of the steel plate, transport the steel plate, plastic film can protect the surface of the steel plate and avoid scratches and ensure that the steel plate is pasted without bubbles
Cutting machine / cutting edge recycling device: horizontal cutting ends the order to reduce waste (linear guide track cutting), vertical cutting meets the requirements of multiple versions, cutting edge grab is to cut the excess sheet to meet the required width
Up and down pressing equipment: Rolled sandwich panel side connection part and corrugated rib of panel
Forming machine: It is used to form the outer panel, which affects the surface quality of the sandwich panel.
Pre-heating device: Pre-heating drying room, pre-heating the base material, so that the polyurethane foam reaches the best conditions, electric heating method
Polyurethane high-pressure foaming machine: Continuous high-pressure foaming machine system, automatic production line, high continuous injection accuracy, online adjustment of various material ratios
Polyurethane pouring equipment: high precision, flexible adjustment, computer controlled mixture uniform pouring
Double-track laminating machine: The core material of the sandwich panel is foamed in the machine, and it is cured and shaped in the laminated state.
Side seal machine: reduce the waste of the chemical material and break the traditional side sealing technology
Double track temperature control heating system: track heating, electric heating, oil heating, gas heating, steam heating
Band Saw Cutting Machine: Online fixed length cutting to meet order requirements
Cooling flip system: uniformly dissipate the pu sanwitch panels to prevent defects caused by uneven heat dissipation immediately after the pu sanwitch panels are stacked.
Vacuum Absorbing Stacker: complete automatic stacking of sandwitch panels
Packing machine: Plastic-seal packaging of the stacked cost plates, automatic placement of pads, and automatic sealing of both ends. Integrated packaging, good plasticity and high degree of automation
