Method and apparatus for molding resin foam product |
摘要 |
An example molding method includes: feeding a molten foamable resin by injection in a cavity formed in a molding die; allowing the molten foamable resin to flow in the cavity; and foaming and solidifying the molten foamable resin to mold a resin foam product. The example molding method performs flow rate control by controlling a flow rate of the molten foamable resin at a welding portion to be equal to or higher than a flow rate of the molten foamable resin at an upstream portion adjacent to the welding portion. |
