Background Technology
[0002] Foamed polymer materials offer numerous advantages, such as high strength, light weight, impact resistance, and thermal insulation. Foamed articles can be manufactured through injection molding or extrusion molding. For example, after melting a polymer material and mixing it with a foaming agent to form a mixture, force or pressure is applied to the mixture to inject or extrude it into the cavity of a mold, where the mixture is allowed to foam and cool to form the foamed article.
[0003] However, it is necessary to improve the properties of foamed products manufactured by injection molding systems, for example, to give different parts of the foamed product different properties. Therefore, improvements are still needed in the structure of the molding apparatus, the injection molding system, and the methods for manufacturing foamed products. Summary of the Invention

[0006] According to a specific embodiment of the present invention, a molding method is provided. The molding method includes: providing a molding apparatus including a first mold, a second mold having a base and a peripheral portion disposed around or above the base, and a third mold; providing a first carrier that can be attached to and detached from the base or the peripheral portion; disposing of a first layer on the first carrier, the first layer comprising a first polymer material; engaging the first carrier to the second mold; engaging the first mold to the second mold to form a first mold cavity, wherein the first carrier and the first layer contained therein are disposed within the first mold cavity; injecting a second polymer material from an injection unit into the first mold cavity to form a second layer and an article comprising the first layer and the second layer made of the second polymer material; and removing the article from the molding apparatus.

The first layer M1 is placed into the first mold cavity 19a before the third polymer material is injected. After the third polymer material is injected from the injection unit 202 into the first mold cavity 19a and forms a third layer M3 from the third polymer material, an article 178 comprising the first layer M1 and the third layer M3 is obtained, and the first carrier 132 may be replaced by another carrier 132a configured to accommodate another layer M4. In some specific embodiments, the first layer M1 and the layer M4 have the same or different patterns or structures, and the pattern formed on the article 178 by the first layer M1 and the pattern formed on the article 178 by the layer M4 may be the same or different.
