A cavity is filled with a foam-in-place insulation by a self-contained dispensing system for which precursor vessel pressures and precursor flow rates decrease as the precursors are dispensed. Flow rate functions for the precursors are pre-calibrated as a function of vessel pressures and / or related parameters such as vessel weights, precursor levels in the vessels, and total volumes dispensed. The cavity is filled by at least one shot of the precursors, each shot comprising a plurality of counts that are announced to a user during the shot. The length of each count and / or the number of counts is / are adjusted according to the flow rate functions in compensation for the decreasing vessel pressures. Embodiments further adjust the count durations for reduced start-up flow at the start of a shot and / or extended flow at the end of a shot, due to mechanical properties and / or user reaction times.

The utility model discloses a double-color watchband forming mold assembly. The double-color watchband forming mold assembly comprises a first mold core, a middle plate matched with the first mold core for use and a second mold core matched with the middle plate for use, the middle plate is buckled with the first mold core for use, and a cavity matched with a first injection product is defined by the middle plate and the first mold core; a cavity which is integrally matched with the watchband is defined between the second mold cavity and the middle plate; when the double-color watchband is formed, a first injection semi-finished product can be formed through the cooperation of the middle plate and the first mold core, then the first injection semi-finished product and the middle plate are taken down together, and a finished product is formed through the cooperation of the middle plate and the second mold core. In the forming process, the semi-finished product does not need to be taken down and placed again, the situation that the semi-finished product shifts is avoided, the position precision is guaranteed, the situation that color crossing occurs in the two-shot forming process is avoided, and the overall machining quality and the qualified rate of products are guaranteed.
