Molding device with self-blocking feed channel

A method of producing a molded module using a plastics die-casting method performed with a molding device that comprises a tool part and a further tool part, which together enclose a cavity, the tool part having at least one dividing wall which is arranged and configured to subdivide the cavity into at least two sub-cavities including a low-pressure sub-cavity and a high-pressure sub-cavity, the tool part having at least two feed channels including a low-pressure-feed channel and a high-pressure feed channel, the low-pressure feed channel opening into the low-pressure sub-cavity and having a smaller cross-section at least over a longitudinal portion than the high-pressure feed channel that opens into the high-pressure sub-cavity, the low-pressure-feed channel being configured to be pressure-resistantly blocked by hardening molding compound during a predetermined time interval, while the high-pressure feed channel is configured to conduct a molding pressure into the cavity for a longer time interval than the low-pressure feed channel, the method comprising:

• introducing a circuit carrier with electronic components into the cavity;
• filling the low-pressure sub-cavity with molding compound via the low-pressure feed channel;
• filling the high-pressure sub-cavity with molding compound via the high-pressure feed channel;
• increasing the molding pressure up to a predetermined low-pressure value, and increasing the molding pressure further up to a high-pressure value after the predetermined time interval after the blocking of the low-pressure feed channel.
