Analytical product: Car bumper

Summary of analysis content: Predict and evaluate the position and appearance of hot nozzle glue before mold opening.

Product materials:PP+T20

Analysis and summary:
●There are great differences between the analyzed materials and the actual materials and the relevant parameters of the injection molding machine, and the parameter values such as deformation and pressure are only for optimization and reference, and cannot be quantified. In the analysis, the holding pressure is 80% of the shot pressure, and the optimization of the relevant parameters (with the test mold) can reduce the deformation, the purpose is to correctly evaluate and provide a wide space for forming optimization to improve the quality and mass production of the product.
● Sequence valve opening sequence: the middle gate is opened first, and the remaining four gates are all opened to G4G5, and the filling pressure is not much different.

●There are 5 fuse lines, in which the confluence Angle of 2 and 4 is increased, and the length is shortened; The actual binding lines at marks 1 and 5 are longer than those analyzed, and the overall appearance is still ideal.
