H.Vet depressions and holes (puffiness):
Dents and holes occurs when there is uneven shrinkage between the material
- Fix: Products: reduced product thickness occurs in places indentations and design of lugs protruding ribs and hard evidence reasonably On site: - Increasing the size and vents to channel from cooling vents soon - Add or large vents vents reasonable Order: Ensure direction flow from region to region thick thin injection molding machines: - Increase the buffer at the end of the period to offset raw spray tot.Khoang this way about 3mm - Increase injection pressure and hold time - Increases the duration of the process and reduction screw injection speed - Reduce heat and energy plasticized mold - Increase cooling time - Check valves open in order to ensure no leakage of material behind
