Heat Preservation And Flame Retardant Metal Panel PU Sandwich Panel
Continuous Production Line
PU sandwich panels are the new generation of decorative wall and
roofing materials, highly favored for use in steel structure
buildings. These panels not only have the role of heat
preservation, but also offer an aesthetic appeal, making them the
only new wall construction material that integrates protection,
decoration, and insulation in one.
PU sandwich panel production line integrates multiple technologies,
including mechanical, chemical, electrical control, hydraulic,
pneumatic, and temperature control systems. It is a multifunctional
fully automated production line that combines uncoiling, film
coating, cutting, forming, preheating, foaming, curing, cutting,
stacking, conveying, and packaging processes into one seamless
operation.

Uncoiler System
The adjustment of the uncoiler is completed by pushing and pulling
the hydraulic cylinder and moving it in a straight line on the
guide rail. This function is used in the production line center
adjustment and change of plate type specifications.
Loading Cart
The loading cart can stop at any time when moving laterally and
lifting up and down, and it has self-locking position protection
when parking.
Forming System
The forming machine system consists of an upper forming machine, a
lower forming machine, a pressing machine platform placed on the
upper pressing machine, and an upper and lower interface track
connecting the forming machine with the preheating furnace.
Plate Preheating Furnace
The heating method of preheating a furnace is heating tube heating.
The heat source heats the air through the heating tube, and this
hot air uniformly heats the steel plate. The hot air in the
preheating furnace establishes a heat cycle by itself, and the
temperature of the hot air can be adjusted.
Double Crawler System
The function of the upper and lower crawler is mainly to overcome
the foaming pressure generated by polyurethane foam to cure and
form, and determine the thickness of the composite plate and the
speed of the production line; The function of the sideband is to
overcome the transverse expansion force generated by polyurethane
foam, determine the width of the composite plate, and play a
precise guiding role in the production process of the composite
plate; As an active mold for continuous operation, the double track
needs to avoid plate deformities and surface scratches to ensure
high-quality composite plates.
Cutting System
The main function of the band saw machine is to automatically
measure the length of the board according to the required board
length and set the corresponding parameters by the user. The band
saw machine automatically cuts the continuous finished board
without stopping the production line. It also absorbs the dust
generated during cutting.
