Five Injection Molding Schedules

Injection Mold: If you want to do well, you have to grasp five injection molding schedules

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, clamping low pressure time, and even Also related to time factors are mold opening and clamping, and the speed of ejection.

1. Injection time

Including the holding time, it generally seems that the longer the injection time, the more saturated the product, but when we pay attention to quality, we must also consider the production capacity. What's more, if the injection time is too long, the product may be too full and cause There are a series of problems such as large ejection deformation size of the sticky mold, so we should comprehensively consider when setting the injection time, and try to shorten the injection time when the quality requirements are met.

2. Melting time

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

3. Cooling time

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

4. Ejection time

The ejection time is generally appropriate to cooperate with the manipulator. When using the manipulator fully automatically, the ejection dwell time is generally kept for 1.5-2 seconds. For semi-automatic production, if the product is dropped or jammed due to the return of the thimble, and the product cannot be removed, the dwell time It should be kept for about 5 seconds.

5. Low voltage protection time

It plays a big role in protecting our personal safety and mold safety. Cooperate with the adjustment of the low pressure position and pressure of the mold. The low pressure protection time should be 1-3 seconds. The shorter the protection time, the smaller the possible harm.
