摘要:
A method of injection molding at least one part in a single mold having therein at least one cavity, the method comprising providing first and second injection molding devices, using the first injection molding device to inject material into the single mold, and thereafter using the second injection molding device to inject material into the single mold.
摘要:
The invention provides a method of co-injection molding. The method includes mixing a plastic inner material and an endothermic-blowing agent to form a core mixture. A plastic outer material is injected from a first injection unit into a co-injection manifold to create a flow of outer material therethrough. The core mixture is injected from a second injection unit into the co-injection manifold to create a flow of core mixture therethrough. The flow of the outer material and the flow of the core mixture are then controlled through the co-injection manifold and into a mold cavity. The core mixture expands as heat is provided for the endothermic-blowing agent to absorb.
