What do you need to pay attention to when closing the mold in glasses factory?
Attention should be paid to the following items when closing the mold in the glasses factory:

Mold opening control: when the molten plastic is injected into the mold cavity and cooled, the product is taken out with the mold opening action.

The mold opening process is also divided into three stages.

In the first stage, the mold is slowly opened to prevent the parts from tearing in the mold cavity.

In the second stage, the mold is opened quickly to shorten the mold opening time.

In the third stage, slowly open the mold to reduce the impact and vibration caused by the inertia of opening the mold.

Mold closing control: mold closing is to close the mold with great mechanical thrust to resist the huge mold opening force caused by high-pressure injection of molten plastic and mold filling during injection molding.
