Cause analysis of brittle transparent products
Bemould injection mold manufacturer manufactures transparent PC molds, electronic product shell plastic molds and new energy battery box molds..., During the production of transparent products, the products are often brittle and easy to break. We carefully sort out the reasons, including the following aspects:
1.Insufficient
injection and pressure holding pressure of injection molding machine;
2.If the
back pressure is too large, the heat of shear and friction increases;
3.The material
test is too high, and the raw materials undergo continuous shear, decomposition
and deterioration;
4.Insufficient injection
and pressure holding time;
5.The shutdown
time of injection molding machine is too long and the injection molding cycle
is too long;
6.Some
parts of the internal structure of the product are too thick, some parts are
too thin and uneven, the consideration of the feeding place is unreasonable,
and the final confluence position of the material flow is at the weak position
of the product structure，
7.Uneven
injection gate feeding and insufficient cold
well;
Knowing the above reasons, we will make a detailed preliminary analysis in the mold design stage to predict possible problems in actual production and optimize in the preliminary stage.
