An injection molding device and related method includes a mold plate with at least one pocket having at least one discharge opening to discharge melted plastic from the pocket into at least one mold cavity interconnected to the pocket and a nozzle including a housing, which during operation is interconnected to the pocket. Per discharge opening a needle is arranged displaceable in an axial direction in the housing between a closed position and an open position. In the closed position the needle closes the thereto related discharge opening and is thereby preventing melted plastic from flowing from the pocket into the at least one mold cavity. In the open position, the needle releases the discharge opening such that melted plastic flows from the pocket into the at least one mold cavity. Furthermore, a melt channel is discharging into the pocket to supply melted plastic into the pocket.

A molding system and a method for operation of the molding system are provided. The method includes flowing a molten polymeric material into a shot tuning chamber from an upstream device, adjusting a temperature of and/or pressure applied to the molten polymeric material in the shot tuning chamber, and flowing the molten polymeric material from the shot tuning chamber into a mold cavity.

A molded circuit board (10) of a camera module (100), manufacturing equipment (200) and a manufacturing method for the molded circuit board. The manufacturing equipment (200) comprises a forming mold (210), which comprises a first mold (211) and a second mold (212) that can be opened or closed, where the first mold (211) and the second mold (212) form a forming cavity (213) when closed. Also, a light window forming block (214) and a base forming guide groove (215) located at the periphery of the light window forming block (214) are provided within the forming cavity (213). When a circuit board is mounted in the forming cavity (213), once a molding material (13) filled into the base forming guide groove (215) is solidified into form by undergoing a transition process from a liquid state to a solid state, a molded base (12) is formed at the position corresponding to the base forming guide groove (215), a through hole of the molded base (12) is formed at the position corresponding to the light window forming block (214), where the molded base (12) is integrally formed on the circuit board so as to form the molded circuit board (10) of the camera module (100). The through hole is used for providing the camera module (100) with an optical path. The molded base (12) can serve as a frame for the camera module (100).
