Analytical product: Car front bumper

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

Product materials:PP+T20

Analysis of the total knot

●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: middle gate opening first, to G2G3 gate opening, G4G5 the same. The maximum filling pressure is 75Mpa from G1 to G2G3. It is recommended to increase the size of fan gate and middle hot nozzle as much as possible to reduce the pressure and mold locking force.

●There are three weld lines in appearance, among which marks 2 and 4 are at the gate, so they are not obvious; Mark 1 and 5 there is no fuse wire, but the actual effect of many factors may exist, the overall appearance is still relatively ideal.
