| 摘要 |
A material feeding hole having an open flow path of the present invention can be disposed to be able to move between one material outlet of a polymer heating and discharging container and one material inlet of a mold and can be disposed between the mold and a mold clamping tool for opening and closing the mold. The same can be used during a polymer processing and producing step. Fed materials can be discharged to the outside by means of a flow path where smelted polymer raw ingredients can be flowed, and a worker can directly take out solidified polymer raw ingredients from the flow path and can more conveniently perform a post-treatment. |
