摘要： In an injection molding process, it can be difficult to detect, in real time, process control variables such as pressure and temperature. Traditional temperature detectors and pressure sensors can be difficult to place in or near a mold cavity. An example embodiment of the present invention includes a self-powered multivariate sensor and uses acoustic transmission. The sensor may employ an infra-red thermal detector and pressure sensor and transmit coded representations of measurements acoustically via a body of the mold. From the temperature and pressure, melt velocity and melt viscosity of a compound in the mold can be determined with a high degree of accuracy by a processor internal to or external from the sensor. The example embodiment maintains structural integrity of the mold, provides a wireless self-powered sensor, and makes available sensing of properties of the viscous compound to enable injection molded parts production at a success rate exceeding 90%.

摘要： Methods and devices are provided for controlling melt pressure in an apparatus that processes molten material. In one exemplary embodiment, the methods and devices utilize a self-regulating valve (10) that is effective to regulate a melt pressure through a melt flow channel (14). In particular, the valve can be adapted to maintain an equilibrium between a control force applied to a control member (16) and a dynamic force applied to the control member by the melt pressure of a melt flowing through a melt flow channel.
