  • Patent number: 7736567
    Abstract: The present invention provides a die with a first die member, a second die member and a holder device between the first die member and the second die member. A film is sent to the die between the holder device and the second die member. And then, operating the holder device toward the second die member to press the film on the second die member, and softening and molding the film in the second die member. Next, moving the first die member toward the second die member to close the die, and then performing an injection molding process to inject a molten material into the die. The molten material is combined with the film to form a product with the film on a surface thereof.
