The activities of Four Process Ltd. started in 1974 and situated in Valley Park, Missouri. This company is an esteemed supplier in the plastic injection molding industry and is woman-owned and family-run.

KURZ has developed this world first together with its subsidiary SCHÖFER. SCHÖFER’s Spinstack Mold tool technology is ideal for manufacturing 2K components using the In-Mold Decoration process (IMD). This composition of the materials ABS/PC and the transparent PMMA enables precisely defined backlighting without undesired light diffusion. As a result, both three-dimensional component geometries and structures for 3D light effects and light barriers can be implemented in a single work step. Deformation, contouring, and decoration are all done in one step. Finishing via hot stamping, digital printing, or the integration of touch sensors are also possible. There are solutions for all customer-specific requirements. This is more than 2K plastic injection molding, this is the highly efficient 2K-IMD-process!

There are approximately 1,200 to 1,500 injection molding companies operating in the United States. These companies range from small businesses to large manufacturers serving diverse markets.
