    Injection mold: To do well, you must master five injection molding progress

    Under the premise of ensuring product quality, the shorter the cycle time, the better. The cycle time includes the following items: injection time, pressure holding time, melting time, cooling time, ejection time, mold clamping low pressure time, and even time factors. Clamping and ejection speed.

    1. Injection time

    Including the holding time, it generally seems that the longer the injection time, the more saturated the product is, but while we pay attention to quality, we must also consider production capacity. More importantly, if the injection time is too long, it may lead to a series of problems such as overfilling the product and causing a large size of sticky mold release deformation. Therefore, we should consider comprehensively when setting the injection time, and try our best to meet the quality requirements. Shorten injection time.

    2. Melting time

    The length depends on the solidification speed of the melt and the size of the back pressure setting, but one thing, the length of the melt time control must be shorter than the cooling time.

    3. Cooling time

    The length of cooling time directly affects the molding cycle. The longer the cooling time, the longer the molding time and the lower the production capacity. Therefore, when we set the high-pressure cooling time, as long as the product can be formed smoothly and will not directly affect problems such as deformation, the shorter the setting time, the better.

    4. Injection time

    The ejection time is generally appropriate to cooperate with the manipulator. When the manipulator is fully automatic, the ejection residence time is generally maintained at 1.5-2 seconds. For semi-automatic production, if the product falls or gets stuck due to the return of the thimble, and the product cannot be taken out, the holding time should be kept for about 5 seconds.

    5. Low voltage protection time

    It has played a great role in protecting our personal safety and mold safety. Cooperate with mold low pressure position and pressure adjustment. The low voltage protection time should be 1-3 seconds. The shorter the protection time, the less possible damage.
