Door panel

Customer's Expectations

Interior parts as door panel obviously require very high cosmetic standard and perfect surface quality. The customer’s target for this application was to avoid also the most challenging defetcs such as pressure lines and a more accurate control of deformation.   

 

Our Solution

With the traditional sequential opening, an important pressure line appeared in the lower central area. Thanks to FLEXflow Evo solution it has been possible to improve the aesthetical appearance by setting a customized opening profile for each drop. The pressure line was definitely removed. This has also allowed, by controlling the pressure in the cavity during the holding phase, to reduce the overall deformation.
