REAL FACTORY · DONGGUAN, CHINAOUR CORE PROCESS
Designed for the mold.
Made for the application.
Compression molding is at the core of our carbon fiber manufacturing approach. We also use autoclave processing for selected automotive components, depending on the part design and agreed manufacturing requirements.
01 Reverse engineering & 3D development
02 Mold design & manufacturing
03 Layup, molding & finishing
WHY JOHHAR
More than a finished part.
Our OEM approach starts with the design and continues through engineering review, tooling, production and inspection.
