Method for injection molding |
摘要 |
A process for producing an injection molded product includes the step of introducing an amount of a molten thermoplastic sufficient for the preparation of the injection molded product into a mold cavity. A quantity of heated gas is introduced into the mold cavity, the molten thermoplastic in the mold cavity thereby forming a gas cavity in the molten thermoplastic. The heated gas is then vented from the gas cavity and a cooling gas is introduced into the gas cavity. The injection molded product is cooled and then the cooling gas is vented from the gas cavity.
