An optical image measuring device 1 splits low-coherence light L0 into signal light LS and reference light LR, and splits an optical path of the reference light LR into two optical paths having different optical path lengths to split the reference light LR into two reference lights LRa, LRb. The method is particularly suitable for long-off-set data, since the first arrival will be a critical refraction event and an automatic picking method may be used. A bottom contact surface of the film sheet bonds with a front contact surface of the structural carrier by diffusion between the contact surfaces thereof within a mold cavity of an injection mold separate from the mold cavity of a vacuum mold which is utilized to vacuum-mold the film sheet to form the desired painted plastic component. The pour chamber has a pour inlet for receiving fluid, and an outlet in fluid communication with the pour inlet.
