Selection of polyurethane equipment

Batch cold storage board production can choose polyurethane two-component high-pressure foaming machine and batch cold storage board laminating machine, the machine picture is as follows:

Two component high pressure foam machine with laminating machine to produce polyurethane cold storage board, this machine has the characteristics of high repeat injection accuracy, even mixing, stable performance, simple operation and high production efficiency. The laminating machine steel plate is made of 16mm Q345B low-alloy steel plate connected with the welded frame of rectangular steel pipe by bolts. The upper and lower formwork of laminating machine can be heated by carbon crystal electric heating plate, and the pre-heating temperature (30-60°) can be freely set by electric control. The upper die adopts gearbox lifting screw (T36*6), a motor, transmission shaft and other mechanisms to achieve synchronous lifting, with the highest height of 600mm. The four peripheral blocks of bottom mold are reinforced by steel plate, and the height can be adjusted up and down (100-200). The clamping screw rod vauling is processed by 45# steel truck, and the plane bearing is installed at the bottom of vauling to reduce the friction resistance. The overall installation Angle of the equipment can be tilted 5° to meet the requirements of foaming process.

Application: this equipment is specially used for foam production of PU polyurethane foam sandwich sheet in the middle of the panel of polyurethane cold storage board or other materials.
