The rotation rate is inadequate. Boost the rate of rotation of this thread. The filling rate is quick. Reduce the injection rate. Injection shaped face peeling happening, the reason is that the recipe for injection moulded components (like additives and color powder) Incomplete mix or exception following fragmentation. Color particles or exclude or additives cannot completely be incorporated. Gate and mould The runner is tiny. Change the gate place or boost the barrier. If necessary, to raise width and the runner diameter. Boost the rear strain. Boost the mould temperature. Mould fever is inadequate. Injection moulding machine. The temperature is large. Reduce. Injection moulding machines’ capacity is inadequate.
