The PU sandwich panel machine is welded by strong steel plates which ensure high strength.Machine frame adopts heat – treatment which help release the welding stress and ensure machine non – deformation. Sand blasting treatment will keep the rust away. Carefully special bottom painting and surface – painting greatly improve anti – corrosion performance and ensure machine long life used. Adopt world – first – class branded spare parts. Quality is further guaranteed.Each machine goes a number of inspection of quality by Guangxing Technical Team before delivery.
The steel plates of Double – belt system adopt multiple time heat treatment with stress relief annealing techinque, then multiple – time rough machining and grinding process by Numerical vertical machining centre, to guarantee the surface with high flatness. Thus it will achieve perfect flatness of the final sandwich panel.
