Four Stages And Precautions Of Injection Mold Opening Process

1. What are the four stages of the injection mold opening process?

Usually refers to the following 4 steps:

1. Mold loading: Load the mold and required raw materials on the injection molding machine to ensure that the machine is in the correct temperature range.

2. Injection: inject the molten plastic into the mold through the screw. Injection pressure and speed are critical to the quality of molded parts.

3. Pressure storage: After injection molding is completed, it is necessary to maintain a certain pressure storage time to ensure that the plastic fully fills the mold cavity and eliminate possible voids or air bubbles.

4. Mold opening: After a certain period of pressure storage, the mold opening operation can be performed. At this time, the machine will open the mold and eject the product at the same time, so as to cut off the connection between the formed object and the remaining material.

2. Matters needing attention in the process of plastic mold opening

1. During the injection process, it is necessary to master the appropriate injection parameters, such as temperature, speed, pressure, etc., to adjust the influencing factors such as plastic flow status, filling status and smoothness.

2. In the mold opening operation, the motor or oil cylinder is driven by the hydraulic pump, so that the mold is separated from the center line and the molded object is ejected. It is usually necessary to control important parameters such as mold opening force, temperature and time.

3. In the injection molding process, it is necessary to strictly control the operation method and its effect at each stage, and timely check whether the machine, mold, raw material or finished product are compliant.

In general, the four stages of plastic injection mould opening process are closely connected, and excellent stamping mold design, precise production management and experienced staff are the key factors to ensure excellent quality of injection molding one.
