Effect of material properties for injection molding shrinkage
(1) the impact on the type of plastic resin shrinkage of different materials of different size shrinkage, even of the same species resin material, different manufacturers or the same manufacturer different batches of the same material, the shrinkage is different. Moreover, since the inherent characteristics of the resin shrinkage range has a narrow width.
(2) the impact of shrinkage glass content
The same plastic shrinkage due to different varieties glass content varies. When increasing the glass fiber content, shrinkage is reduced,
Usually mass fraction in the thermoplastic resin is 20% to 40% of the glass, the shrinkage rate can be reduced 1/4 to 1/2.
But derived from the practice of injection molding, on the stream flow direction, this is almost not affect the thickness of the plastic parts. In the stream in a vertical direction, in the case of constant wall thickness, shrinkage with increasing glass content decreases; in the case of thin-walled plastic parts shrinkage almost independent of glass content Impact.
