Polyurethane sandwich panel production line made by korea Hi-tech.Factory area is 70,000 ㎡ with more than 600 staffs and ten overseas branch offices. As part of the Hennecke GROUP, HENNECKE-OMS offers the largest worldwide range of sandwich panel plants for manufacturing components and insulating panels with a sandwich-like structure and helps to realize numerous product variations for a wide range of applications.
2. Hot air circulation furnace strictly controls PU foaming and solidification temperature in suitable range. We can therefore say that the production process of sandwich panels is multi-parametrical pu sandwich panel line and multi-dimensional. EPS Forming machine adopts PLC and touch screen control, automatic filling, electronic weighing, temperature control, material level to realize automatic production.

Established in 1990, Hongfa Heavy Machinery Co., Ltd has made a number of milestones in R&D construction machines for building materials processing and manufactured many reliable and cutting edge machines, such as cement block making machines, concrete ready mix plant, AAC block production line, concrete pipe machine, automatic block cuber, terrazzo tile making machine and concrete light weight sandwich wall panel making machines and production line.

High precise guiding pressure reducing valve controls the temperature and steam pressure of the closed barrel, ensuring the outcome pressure of the valve constant and the inner temperature controlled within ±1%, which keeps the foamed material equal and prevents the bead agglomerate because of the bad temperature control.
According to different usage of insulated panels, PU Sandwich Panel can be divided into three typesWall panel, Roof panel, Cold Store Sandwich Panel. Click the button below to add the CONTINUOUS PRODUCTION LINES FOR SANDWICH PANELS to your wish list. Within 15 years hard working, Wuxi Weihua Machinery has finished the whole PU sandwich panel production line by ourselves and got several patents, especially the foaming machine and flat PU sheet are superior of the field.

Our PU sandwich panel has high strength and durability of insulating ability. To have the best foaming result, FIRST offer a whole kit for the high pressure thermoregulation for each chemical material. Values of 40mm thickness of sandwich Panel production is given for the condition.
Hongfa integrate the design, development, manufacturing, and sales of the lightweight EPS wall panel machinery. 4. The sandwich panel laminator uses rubber-coated roller type laminator to protect the color paint on the colored steel as well as during the pressurizing of the sandwich panel.

The panel line includes machinery part electrical control system part and additional machine for panel. sandwich panel laminator has a high quality and thick wall rectangular steel welding method, and to get rid of the rust, polishing, smoothing and aging treament.
