Application of water jet in pet aluminum-plastic composite

PET composite material is a new type of structural composite plate product.It is made of metal sheet as the panel and pet invoice material as the core material, and is continuously compounded online at high temperature. Due to the inconsistent thermal melting points of the materials in the composite layer, it is obviously not suitable to use the processing method of thermal cutting. The traditional processing method is usually mechanical cutting, that is, cutting with grinding wheel or saw blade. This method is easy to produce two kinds of defects: first, notch damage, that is, notch delamination, tearing, burr, wire drawing and other phenomena near the edge of the notch.The second is interlaminar delamination, that is the separation between composite layers makes the internal structure of the component loose and reduces the strength of the component. Because ultra-high pressure water jet cutting belongs to non-contact cold processing technology, there is no delamination in processing, and the material will not appear coking and hot cracking. The water jet cutting speed is fast, and the fine sand in sanding cutting also has the effect of grinding, making the cutting surface smooth, smooth and accurate.

Our company adopts a dual-intensifier design intensifier pump (ww60jet) for the working conditions of assembly line, which has the ability to work independently with single and dual cores. The ability of independent communication can quickly and simply connect the general control system of the assembly line, so that it can be opened and used immediately. The design of water jet cutting system can solve the problem of the service life of nozzles and sandblasting pipes. With the dual intensifier design, one for standby and one for use, it can meet the never-stop maintenance.
