What are the Injection Mold Opening Process and Precautions?

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 the required raw materials on the injection molding machine and 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 crucial to the quality of the molded parts.

(3) Pressure storage: After the 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 eliminates possible gaps or 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 to cut off the connection between the molded object and the remaining material.

2. What are the precautions for the plastic mold opening process?

(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, filling state and finish.

(2) During the mold opening operation, the motor or cylinder is driven by a hydraulic pump to separate the mold from the center line and eject the molded object. It is usually necessary to control important parameters such as mold opening force, temperature and time.

(3) During the injection molding process, it is necessary to strictly control the operation methods and effects of each stage, and check whether the machine, mold, raw materials or finished products are compliant in a timely manner.

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