System for injection molding
A method of and system for injection molding is shown. The method can include the positioning one or more metal components in a mold, aligning a film for transferring an image from the film onto a surface of a plastic component, injecting a material into the mold to form the plastic component such that the metal component will be embedded in the plastic component and transferring the image from the film onto the surface of the plastic component that has the embedded metal component. The method can also include the removing the transferred image from the metal component if at least a portion of the transferred image adheres to the metal component.
1. A system for injection molding, comprising:
a mold that includes a first mold block and a second mold block;
a support structure provided in the first mold block to fixedly secure a metal component;
a positioning machine that affixes the metal component onto the support structure;
a nozzle that is configured to inject a material into the mold to form a plastic component having a plastic surface such that the metal component is integrated with the plastic surface; and
a film feeder that is configured to feed film through the mold, wherein the film contains one or more images that adhere to the plastic surface formed from the material injected into the mold and wherein the one or more images extend over the metal component integrated with the plastic surface.
2. The system according to claim 1 , wherein the mold has an ejection mechanism that is configured to remove the plastic component from the mold once the plastic component has been cured.
3. The system according to claim 1 , wherein one of or both of the first mold block and the second mold block has a mold cavity for receiving the material from the nozzle.
4. The system according to claim 3 , wherein the film feeder includes one or more spools to which the film is attached, and the film feeder is further configured to feed the film through the mold by passing the film between the first mold block and the second mold block when the first mold block and the second mold block are separated from one another.
5. The system according to claim 1 , wherein the metal component is a mesh designed to cover an audio port, a logo, a charger interface or a camera interface.
6. The system according to claim 1 , wherein the material injected into the mold is a thermoplastic or thermosetting plastic material.
7. The system according to claim 3 , further comprising a pressing mechanism that is operable to bring the first mold block and the second mold block into sealed contact with one another prior to the material being injected into the mold and to subsequently separate the first mold block and the second mold block.
8. The system according to claim 1 , further comprising a heating element that is configured to heat the material prior to entering the nozzle.
9. The system according to claim 1 , wherein the film feeder is configured to advance the film each time an image is transferred onto the plastic surface.
10. The system according to claim 1 , wherein the film feeder is configured to push film through the mold.
11. The system according to claim 1 , wherein the film feeder comprises supports and spools.
12. The system according to claim 3 , wherein a partial vacuum is created in the second mold block.
13. The system according to claim 1 , wherein the film feeder is capable of feeding film having a texture.
14. The system according to claim 1 , wherein the film has a pre-printed texture.
15. The system according to claim 1 , further comprising an ejector mechanism including ejector pins.
16. The system according to claim 4 , further comprising a pressing mechanism that is operable to bring the first mold block and the second mold block into sealed contact with one another prior to the material being injected into the mold and to subsequently separate the first mold block and the second mold block.
17. The system according to claim 16 , further comprising a heating element that is configured to heat the material prior to entering the nozzle.
18. The system according to claim 17 , wherein a partial vacuum is created in the second mold block.
19. The system according to claim 1 , further comprising an image remover configured to remove a portion of the transferred image that adheres to the metal component.
