Remarks (1)Resin need to 150℃ dry 2~4 hours before use.
(2)This process conditions only for reference data, production need according to processing conditions appropriate adjustments.
(3)Production materials don’t in the screw retention time more than 10 minutes, the production after need crowded empty in the machine, and cleaning material feeding cleaning nitrogen-treated barrel.
(4)Because of polyimide matrix harmony refers to the low flow, it is recommended to use a shorter, sprue older (flat gate) injection mold.
(5)Suggest products heat treatment in oven with 160~180℃ 2 hours before use.
