(1) PC/ABS enables functional spoiler struts to achieve weight reduction of 86%


The PC/ABS function spoiler strut not only has a stylish shape, good aerodynamic performance, but also has a weight reduction of 86% while meeting the strength/stiffness requirements.

In addition, an innovative connection scheme is used to connect the struts to the spoiler and the vehicle without exposing the long bolts and compression stops of the fixture. This uniquely designed mold core puller enables hollow pillars.



(2) Glass fiber reinforced PA reduces the intake grille by 20%


The PA6+35%GF injection molded plastic metal composite is suitable for the intake grille, replacing two separate systemsreducing 20 individual components, reducing weight by 1.76 pounds and saving approximately $8.


The process also improves the sealing effect, which improves the performance of the heat exchanger. This process can also be extended to other OEMs or vehicles.


(3) PP honeycomb panel reduces door weight by 24%

Traditional wooden door trim components are multi-layered structures made from multiple layers of wood veneers that require 20 complex forming and machining operations, including milling.


The PP honeycomb panel is made of molding equipment and the parts are processed by insert molding. Compared with traditional wood products, the weight is reduced he PP honeycomb panel is made of molding equipment and the parts are processed by insert molding. Compared with traditional wood products, the weight is reduced by 24% and the cost is reduced by 65%. The PP honeycomb structure imparts better flexibility, thermal insulation and sound insulation.
