Instruction

If you are looking for the manufacturer of PU and rockwool (mineral wool) sandwich panel production line, YONGMING is always at your service.

Our Advantages
YONGMING takes pride in manufacturing and selling sandwich panel machinery for 16 years, and our products have been highly praised by customers from Russia, Spain, Italy and other countries.

To cater for great market demand, we developed this PU and mineral wool sandwich panel production line in 2012 through applying special crafts. Different from common machines, our line boasts high automaticity and enables to produce sandwich panel of 300mm thick and with excellent heat insulation effect.

In contrast, the line manufactured by competitors from European countries only can produce panel of 150mm thick. Hence, it is apparent that YONGMING has absolute predominance in this industry, and our PU and rockwool sandwich panel production line is more preferred by countries located in low-temperature regions, such as Russia, Finland, etc. In addition, it brings you high production efficiency which is 3 times more than common lines, thus saving production time and cost for you. For large-scale manufacturers, this machine is strongly recommended.

Work Flow
This building material manufacturing equipment accommodates 3 types of work flow as below:

1. Liquid PU is poured between top and bottom steel sheets, and PU foaming takes place when the liquid PU is processed by PU foaming system and caterpillar laminating machine. Finally, solidified steel sheets are cut by cut-to-length band saw.

2. Rock wool or mineral wool is padded between top and bottom steel sheets by our PU and rockwool sandwich panel production line. After glue coating and laminating, core material is adhered to steel sheets. Finally, sandwich panel with required size is obtained after cutting and solidifying.

3. After padding top and bottom steel sheets with rock wool or mineral wool, glue coating, PU foaming and laminating are performed by sandwich panel line. Then, cut-to-length band saw is used to cut solidified steel sheets.

Technical Parameters
1. Running speed: 0-8m/min. (stepless variable-frequency speed regulation)
2. Overall dimension: 110m×16m×6.5m (customizable)
3. Installed power: 350KW
4. Production capacity:
a. Theoretical production capacity: 360m2 (M=KTV=1×60×6=360m2, 1000mm wide, 50mm thick)
b. Actual production capacity per hour depends on PU pouring volume as well as PU foaming and solidifying time. Generally, the production capacity of our PU and rockwool sandwich panel production line is 2-6m per minute.
