AI Technical Summary
In injection molding, the differences in PVT properties of resin materials lead to unstable molding quality. In particular, recycled materials have large deviations in PVT properties. Existing technologies require multiple experiments and are costly, making it difficult to build a low-cost PVT property calculation model.
The PVT property calculation model estimation system uses known material PVT property calculation models and sensor data to generate predetermined relationships, thereby estimating the PVT property calculation model for unknown materials, reducing the number of experiments and costs.
It enables rapid and low-cost estimation of the PVT characteristics of resin materials, improving the stability of the molding quality of recycled materials and the accuracy of molding condition adjustment.
