Abstract
An injection molding method is provided. A molding device is provided and includes a first mold, a second mold over the first mold and a mold cavity defined by the first mold and the second mold. A first mixture is injected into the mold cavity through a first feeding port. A first component is formed from the first mixture. A second mixture is injected into the mold cavity through a second feeding port. A second component is formed from the second mixture. The second component is at least partially contact with the first component, and the first component and the second component have different physical properties.

An injection molding method, comprising:
- providing a molding device including a first mold, a second mold over the first mold and a mold cavity defined by the first mold and the second mold;
- injecting a first mixture into the mold cavity through a first feeding port;
- forming a first component from the first mixture;
- injecting a second mixture into the mold cavity through a second feeding port;
- and
- forming a second component from the second mixture,
- wherein the second component is at least partially contact with the first component, and the first component and the second component have different physical properties.
