Methods and systems of delivering liquid additives in a molding system are provided. A charging sensor is provided to monitor the status of the injection charging mechanism of the molding system which charges, meters or doses an injection volume of molding material. A dosing instruction is generated based on the charging status signal. The additive pump controls the delivering of the liquid additives into the injection unit based on the dosing instruction, while the injection charging mechanism is charging the injection volume of molding material.

An LED luminaire and potting method having the following steps: introducing a configured luminaire into an at least partly optically transparent potting mold (16), such that the luminaire does not come into contact with the walls of the potting mold; introducing an optically transparent potting compound (18) into the potting mold (16) until at least the luminaire is surrounded; and detecting a quantity of bubbles by an optical sensor or image detector (14), wherein the pressure in the vacuum chamber (11) is controlled in order to influence the bubbles and/or a pivot/inclination device (12) is controlled in order to move the vacuum chamber (11) and/or the potting mold (16) in order to expel detected gas/air bubbles (19) out of the optically transparent potting compound (18).

A controller for an injection molding system is in communication with a melt flow control unit, a gas assist control unit, and a gas counter pressure control unit. The controller can effect real-time adjustments to gas assist pressure and/or gas counter pressure as a function of melt pressure or flow front position.

A temperature control apparatus includes a temperature control branch connected to a feed line for a temperature control medium, a pump system including a pump for conveying the medium, a pump open-loop or closed-loop control device for controlling the output of the pump system, a throttle device having a variable degree of opening for throttling a quantitative through-flow of the medium in the temperature control branch, and an open-loop or closed-loop control device with the degree of opening of the throttle device as a setting value and with a control variable from the group: degree of opening of the throttle device, temperature, temperature difference, through-flow, pressure or a physical value to be derived from that group. The pump open-loop or closed-loop control device is configured to control an operation of the pump to adjust the delivery output of the pump system depending on the degree of opening of the throttle device.
