Processing machine and methods for processing dip-molded articles
Processes for the manufacturing of dip-molded articles can include the application of compression to remove molding materials from within the dip-molded articles. In some embodiments, inflatable implantable medical devices are dip-molded and can be manufactured using such compression processes.
1. A dip-molded article processing machine comprising:
a first conveyor assembly defining a first conveyor surface;
a first compression section comprising one or more compression rollers with an outer peripheral surface spaced apart from the first conveyor surface by a first gap distance, the compression rollers configured to directly contact the dip-molded article;
a second compression section comprising a second conveyor assembly defining a second conveyor surface, the second conveyor surface facing the first conveyor surface and spaced apart from the first conveyor surface by a second gap distance, wherein the first gap distance is greater than a minimum gap distance of the second gap distance; and at least one an electric motor that, when actuated, concurrently drives the first conveyor assembly, the one or more compression rollers, and the second conveyor assembly.
2. The machine of claim 1 , wherein the first conveyor surface and the second conveyor surface are generally planar, non-parallel surfaces.
3. The machine of claim 1 , wherein the second gap distance decreases along the longitudinal length of the second conveyor surface.
4. The machine of claim 1 , wherein the second gap distance monotonically decreases along the longitudinal length of the second conveyor surface.
5. The machine of claim 1 , further comprising a power source configured to concurrently drive the first conveyor assembly, the one or more compression rollers, and the second conveyor assembly at a substantially equal linear speed.
6. The machine of claim 1 , wherein at least one of the first gap distance and the second gap distance are adjustable.
7. The machine of claim 1 , wherein the second gap distance differs along a longitudinal length of the second conveyor surface.
8. The machine of claim 1 , further comprising one or more additional conveyor surfaces facing the first conveyor surface.
9. The machine of claim 8 , wherein the first conveyor surface is longer than a combined length of the second conveyor surface and the one or more additional conveyor surfaces.
10. A dip-molded article processing machine comprising:
a first conveyor assembly defining a first conveyor surface; a first compression section comprising one or more compression rollers with an outer peripheral surface spaced apart from the first conveyor surface by a first gap distance; the compression rollers configured to directly contact the dip-molded article;
a second compression section comprising a second conveyor assembly defining a second conveyor surface, the second conveyor surface facing the first conveyor surface and spaced apart from the first conveyor surface by a second gap distance, wherein the first conveyor surface is longer than the second conveyor surface; and at least one an electric motor that, when actuated, concurrently drives the first conveyor assembly, the one or more compression rollers, and the second conveyor assembly.
11. The machine of claim 10 , wherein the first conveyor surface and the second conveyor surface are generally planar, non-parallel surfaces.
12. The machine of claim 10 , wherein the second gap distance decreases along the longitudinal length of the second conveyor surface.
13. The machine of claim 10 , wherein the second gap distance monotonically decreases along the longitudinal length of the second conveyor surface.
14. The machine of claim 10 , further comprising a power source configured to concurrently drive the first conveyor assembly, the one or more rollers, and the second conveyor assembly at a substantially equal linear speed.
15. The machine of claim 10 , wherein at least one of the first gap distance and the second gap distance are adjustable.
16. The machine of claim 10 , wherein the second gap distance differs along a longitudinal length of the second conveyor surface.
17. The machine of claim 10 , further comprising one or more additional conveyor surfaces facing the first conveyor surface.
18. A dip-molded article processing machine comprising:
a first conveyor assembly defining a first conveyor surface;
a first compression section comprising one or more compression rollers with an outer peripheral surface spaced apart from the first conveyor surface by a first gap distance, the compression rollers configured to directly contact the dip-molded article;
a second compression section comprising a second conveyor assembly defining a second conveyor surface, the second conveyor surface facing the first conveyor surface and spaced apart from the first conveyor surface by a second gap distance; and
at least one manual crank mechanism that, when rotated, concurrently drives the first conveyor assembly, the one or more rollers, and the second conveyor assembly.
